# 3.1. abort_noattach
# 
# Type: quadoption
# Default: no
# 
# When the body of the message matches $abort_noattach_regexp and there are no
# attachments, this quadoption controls whether to abort sending the message.
# 
set abort_noattach=ask-yes


# 3.2. abort_noattach_regexp
# 
# Type: regular expression
# Default: “attach”
# 
# Specifies a regular expression to match against the body of the message, to
# determine if an attachment was mentioned but mistakenly forgotten. If it
# matches, $abort_noattach will be consulted to determine if message sending will
# be aborted.
# 
# Like other regular expressions in Mutt, the search is case sensitive if the
# pattern contains at least one upper case letter, and case insensitive
# otherwise.

# 3.3. abort_nosubject
# 
# Type: quadoption
# Default: ask-yes
# 
# If set to yes, when composing messages and no subject is given at the subject
# prompt, composition will be aborted. If set to no, composing messages with no
# subject given at the subject prompt will never be aborted.
# 


# 3.4. abort_unmodified
# 
# Type: quadoption
# Default: yes
# 
# If set to yes, composition will automatically abort after editing the message
# body if no changes are made to the file (this check only happens after the
# first edit of the file). When set to no, composition will never be aborted.
# 


# 3.5. alias_file
# 
# Type: path
# Default: “~/.muttrc”
# 
# The default file in which to save aliases created by the <create-alias>
# function. Entries added to this file are encoded in the character set specified
# by $config_charset if it is set or the current character set otherwise.
# 
# Note: Mutt will not automatically source this file; you must explicitly use the
# “source” command for it to be executed in case this option points to a
# dedicated alias file.
# 
# The default for this option is the currently used muttrc file, or “~/.muttrc”
# if no user muttrc was found.
# 
set alias_file="$my_confdir/aliases"


# 3.6. alias_format
# 
# Type: string
# Default: “%4n %2f %t %-10a   %r”
# 
# Specifies the format of the data displayed for the “alias” menu. The following
# printf(3)-style sequences are available:
# 
# ┌──┬──────────────────────────────────────────────────────────────┐ 
# │%a│alias name                                                    │

# ├──┼──────────────────────────────────────────────────────────────┤ 
# │%t│character which indicates if the alias is tagged for inclusion│
# └──┴──────────────────────────────────────────────────────────────┘ 
# 


# 3.7. allow_8bit
# 
# Type: boolean
# Default: yes
# 
# Controls whether 8-bit data is converted to 7-bit using either Quoted-
# Printable or Base64 encoding when sending mail.
# 


# 3.8. allow_ansi
# 
# Type: boolean
# Default: no
# 
# Controls whether ANSI color codes in messages (and color tags in rich text
# messages) are to be interpreted. Messages containing these codes are rare, but
# if this option is set, their text will be colored accordingly. Note that this
# may override your color choices, and even present a security problem, since a
# message could include a line like
# 
# [-- PGP output follows ...
# 
# and give it the same color as your attachment color (see also $crypt_timestamp
# ). 
# 


# 3.9. arrow_cursor
# 
# Type: boolean
# Default: no
# 
# When set, an arrow (“->”) will be used to indicate the current entry in menus
# instead of highlighting the whole line. On slow network or modem links this
# will make response faster because there is less that has to be redrawn on the
# screen when moving to the next or previous entries in the menu.
# 


# 3.10. ascii_chars
# 
# Type: boolean
# Default: no
# 
# If set, Mutt will use plain ASCII characters when displaying thread and
# attachment trees, instead of the default ACS characters.
# 


# 3.11. askbcc
# 
# Type: boolean
# Default: no
# 
# If set, Mutt will prompt you for blind-carbon-copy (Bcc) recipients before
# editing an outgoing message.
# 


# 3.12. askcc
# 
# Type: boolean
# Default: no
# 
# If set, Mutt will prompt you for carbon-copy (Cc) recipients before editing the
# body of an outgoing message.
# 


# 3.13. assumed_charset
# 
# Type: string
# Default: (empty)
# 
# This variable is a colon-separated list of character encoding schemes for
# messages without character encoding indication. Header field values and message
# body content without character encoding indication would be assumed that they
# are written in one of this list. By default, all the header fields and message
# body without any charset indication are assumed to be in “us-ascii”.
# 
# For example, Japanese users might prefer this:
# 
# set assumed_charset="iso-2022-jp:euc-jp:shift_jis:utf-8"
# 
# However, only the first content is valid for the message body.
# 


# 3.14. attach_charset
# 
# Type: string
# Default: (empty)
# 
# This variable is a colon-separated list of character encoding schemes for text
# file attachments. Mutt uses this setting to guess which encoding files being
# attached are encoded in to convert them to a proper character set given in
# $send_charset. 
# 
# If unset, the value of $charset will be used instead. For example, the
# following configuration would work for Japanese text handling:
# 
# set attach_charset="iso-2022-jp:euc-jp:shift_jis:utf-8"
# 
# Note: for Japanese users, “iso-2022-*” must be put at the head of the value as
# shown above if included.
# 


# 3.15. attach_format
# 
# Type: string
# Default: “%u%D%I %t%4n %T%.40d%> [%.7m/%.10M, %.6e%?C?, %C?, %s] ”
# 
# This variable describes the format of the “attachment” menu. The following

# For an explanation of “soft-fill”, see the $index_format documentation.
# 


# 3.16. attach_save_dir
# 
# Type: path
# Default: (empty)
# 
# The default directory to save attachments from the “attachment” menu. If it
# doesn't exist, Mutt will prompt to create the directory before saving.
# 
# If the path is invalid (e.g. not a directory, or cannot be chdir'ed to), Mutt
# will fall back to using the current directory.
# 
set attach_save_dir=$tmpdir


# 3.17. attach_sep
# 
# Type: string
# Default: “n”
# 
# The separator to add between attachments when operating (saving, printing,
# piping, etc) on a list of tagged attachments.
# 


# 3.18. attach_split
# 
# Type: boolean
# Default: yes
# 
# If this variable is unset, when operating (saving, printing, piping, etc) on a
# list of tagged attachments, Mutt will concatenate the attachments and will
# operate on them as a single attachment. The $attach_sep separator is added
# after each attachment. When set, Mutt will operate on the attachments one by
# one. 
# 


# 3.19. attribution
# 
# Type: string (localized)
# Default: “On %d, %n wrote:”
# 
# This is the string that will precede a message which has been included in a
# reply. For a full listing of defined printf(3)-like sequences see the section
# on $index_format.
# 
set attribution="$my_attribution_en"


# 3.20. attribution_locale
# 
# Type: string
# Default: (empty)
# 
# The locale used by strftime(3) to format dates in the attribution string. Legal
# values are the strings your system accepts for the locale environment variable
# $LC_TIME. 
# 
# This variable is to allow the attribution date format to be customized by
# recipient or folder using hooks. By default, Mutt will use your locale
# environment, so there is no need to set this except to override that default.
# 


# 3.21. auto_subscribe
# 
# Type: boolean
# Default: no
# 
# When set, Mutt assumes the presence of a List-Post header means the recipient
# is subscribed to the list. Unless the mailing list is in the “unsubscribe” or “
# unlist” lists, it will be added to the “subscribe” list. Parsing and checking
# these things slows header reading down, so this option is disabled by default.
# 


# 3.22. auto_tag
# 
# Type: boolean
# Default: no
# 
# When set, functions in the index menu which affect a message will be applied to
# all tagged messages (if there are any). When unset, you must first use the
# <tag-prefix> function (bound to “;” by default) to make the next function apply
# to all tagged messages.
# 


# 3.23. autocrypt
# 
# Type: boolean
# Default: no
# 
# When set, enables autocrypt, which provides passive encryption protection with
# keys exchanged via headers. See “autocryptdoc” for more details. (Autocrypt
# only) 
# 


# 3.24. autocrypt_acct_format
# 
# Type: string
# Default: “%4n %-30a %20p %10s”
# 
# This variable describes the format of the “autocrypt account” menu. The
# following printf(3)-style sequences are understood
# 
# ┌──┬─────────────────────────────┐ 
# │%a│email address                │

# 
# (Autocrypt only)
# 


# 3.25. autocrypt_dir
# 
# Type: path
# Default: “~/.mutt/autocrypt”
# 
# This variable sets where autocrypt files are stored, including the GPG keyring
# and sqlite database. See “autocryptdoc” for more details. (Autocrypt only)
# 


# 3.26. autocrypt_reply
# 
# Type: boolean
# Default: yes
# 
# When set, replying to an autocrypt email automatically enables autocrypt in the
# reply. You may want to unset this if you're using the same key for autocrypt as
# normal web-of-trust, so that autocrypt isn't forced on for all encrypted
# replies. (Autocrypt only)
# 


# 3.27. autoedit
# 
# Type: boolean
# Default: no
# 
# When set along with $edit_headers, Mutt will skip the initial send-menu
# (prompting for subject and recipients) and allow you to immediately begin
# editing the body of your message. The send-menu may still be accessed once you
# have finished editing the body of your message.
# 
# Note: when this option is set, you cannot use send-hooks that depend on the
# recipients when composing a new (non-reply) message, as the initial list of
# recipients is empty.
# 
# Also see $fast_reply.
# 
set autoedit=yes


# 3.28. background_edit
# 
# Type: boolean
# Default: no
# 
# When set, Mutt will run $editor in the background during message composition. A
# landing page will display, waiting for the $editor to exit. The landing page
# may be exited, allowing perusal of the mailbox, or even for other messages to
# be composed. Backgrounded sessions may be returned to via the
# <background-compose-menu> function.
# 
# For background editing to work properly, $editor must be set to an editor that
# does not try to use the Mutt terminal: for example a graphical editor, or a
# script launching (and waiting for) the editor in another Gnu Screen window.
# 
# For more details, see “bgedit” ("Background Editing" in the manual).
# 


# 3.29. background_confirm_quit
# 
# Type: boolean
# Default: yes
# 
# When set, if there are any background edit sessions, you will be prompted to
# confirm exiting Mutt, in addition to the $quit prompt.
# 


# 3.30. background_format
# 
# Type: string
# Default: “%10S %7p %s”
# 
# This variable describes the format of the “background compose” menu. The
# following printf(3)-style sequences are understood:
# 
# ┌──┬──────────────────────────────────────────────────────┐ 
# │%i│parent message id (for replies and forwarded messages)│

# 


# 3.31. beep
# 
# Type: boolean
# Default: yes
# 
# When this variable is set, mutt will beep when an error occurs.
# 
set beep=no


# 3.32. beep_new
# 
# Type: boolean
# Default: no
# 
# When this variable is set, mutt will beep whenever it prints a message
# notifying you of new mail. This is independent of the setting of the $beep
# variable. 
# 


# 3.33. bounce
# 
# Type: quadoption
# Default: ask-yes
# 
# Controls whether you will be asked to confirm bouncing messages. If set to yes
# you don't get asked if you want to bounce a message. Setting this variable to
# no is not generally useful, and thus not recommended, because you are unable to
# bounce messages.
# 


# 3.34. bounce_delivered
# 
# Type: boolean
# Default: yes
# 
# When this variable is set, mutt will include Delivered-To headers when bouncing
# messages. Postfix users may wish to unset this variable.
# 
set bounce_delivered=no


# 3.35. braille_friendly
# 
# Type: boolean
# Default: no
# 
# When this variable is set, mutt will place the cursor at the beginning of the
# current line in menus, even when the $arrow_cursor variable is unset, making it
# easier for blind persons using Braille displays to follow these menus. The
# option is unset by default because many visual terminals don't permit making
# the cursor invisible.
# 


# 3.36. browser_abbreviate_mailboxes
# 
# Type: boolean
# Default: yes
# 
# When this variable is set, mutt will abbreviate mailbox names in the browser
# mailbox list, using '~' and '=' shortcuts.
# 
# The default "alpha" setting of $sort_browser uses locale-based sorting (using
# strcoll(3)), which ignores some punctuation. This can lead to some situations
# where the order doesn't make intuitive sense. In those cases, it may be
# desirable to unset this variable.
# 


# 3.37. browser_sticky_cursor
# 
# Type: boolean
# Default: yes
# 
# When this variable is set, the browser will attempt to keep the cursor on the
# same mailbox when performing various functions. These include moving up a
# directory, toggling between mailboxes and directory listing, creating/renaming
# a mailbox, toggling subscribed mailboxes, and entering a new mask.
# 


# 3.38. certificate_file
# 
# Type: path
# Default: “~/.mutt_certificates”
# 
# This variable specifies the file where the certificates you trust are saved.
# When an unknown certificate is encountered, you are asked if you accept it or
# not. If you accept it, the certificate can also be saved in this file and
# further connections are automatically accepted.
# 
# You can also manually add CA certificates in this file. Any server certificate
# that is signed with one of these CA certificates is also automatically
# accepted. 
# 
# Example: 
# 
# set certificate_file=~/.mutt/certificates
# 


# 3.39. change_folder_next
# 
# Type: boolean
# Default: no
# 
# When this variable is set, the <change-folder> function mailbox suggestion will
# start at the next folder in your “mailboxes” list, instead of starting at the
# first folder in the list.
# 


# 3.40. charset
# 
# Type: string
# Default: (empty)
# 
# Character set your terminal uses to display and enter textual data. It is also
# the fallback for $send_charset.
# 
# Upon startup Mutt tries to derive this value from environment variables such as
# $LC_CTYPE or $LANG.
# 
# Note: It should only be set in case Mutt isn't able to determine the character
# set used correctly.
# 


# 3.41. check_mbox_size
# 
# Type: boolean
# Default: no
# 
# When this variable is set, mutt will use file size attribute instead of access
# time when checking for new mail in mbox and mmdf folders.
# 
# This variable is unset by default and should only be enabled when new mail
# detection for these folder types is unreliable or doesn't work.
# 
# Note that enabling this variable should happen before any “mailboxes”
# directives occur in configuration files regarding mbox or mmdf folders because
# mutt needs to determine the initial new mail status of such a mailbox by
# performing a fast mailbox scan when it is defined. Afterwards the new mail
# status is tracked by file size changes.
# 


# 3.42. check_new
# 
# Type: boolean
# Default: yes
# 
# Note: this option only affects maildir and MH style mailboxes.
# 
# When set, Mutt will check for new mail delivered while the mailbox is open.
# Especially with MH mailboxes, this operation can take quite some time since it
# involves scanning the directory and checking each file to see if it has already
# been looked at. If this variable is unset, no check for new mail is performed
# while the mailbox is open.
# 


# 3.43. collapse_unread
# 
# Type: boolean
# Default: yes
# 
# When unset, Mutt will not collapse a thread if it contains any unread messages.
# 


# 3.44. compose_format
# 
# Type: string (localized)
# Default: “-- Mutt: Compose  [Approx. msg size: %l   Atts: %a]%>-”
# 
# Controls the format of the status line displayed in the “compose” menu. This
# string is similar to $status_format, but has its own set of printf(3)-like
# sequences: 
# 
# ┌──┬──────────────────────────────────────────────────────────────────────────┐

# Please note that if setting $charset it must be done before setting
# $config_charset. 
# 
# Recoding should be avoided as it may render unconvertable characters as
# question marks which can lead to undesired side effects (for example in regular
# expressions). 
# 


# 3.46. confirmappend
# 
# Type: boolean
# Default: yes
# 
# When set, Mutt will prompt for confirmation when appending messages to an
# existing mailbox.
# 
set confirmappend=no


# 3.47. confirmcreate
# 
# Type: boolean
# Default: yes
# 
# When set, Mutt will prompt for confirmation when saving messages to a mailbox
# which does not yet exist before creating it.
# 


# 3.48. connect_timeout
# 
# Type: number
# Default: 30
# 
# Causes Mutt to timeout a network connection (for IMAP, POP or SMTP) after this
# many seconds if the connection is not able to be established. A negative value
# causes Mutt to wait indefinitely for the connection attempt to succeed.
# 


# 3.49. content_type
# 
# Type: string
# Default: “text/plain”
# 
# Sets the default Content-Type for the body of newly composed messages.
# 
set content_type="text/plain; markup=markdown"


# 3.50. copy
# 
# Type: quadoption
# Default: yes
# 
# This variable controls whether or not copies of your outgoing messages will be
# saved for later references. Also see $record, $save_name, $force_name and “
# fcc-hook”. 
# 
set copy=yes


# 3.51. copy_decode_weed
# 
# Type: boolean
# Default: no
# 
# Controls whether Mutt will weed headers when invoking the <decode-copy> or
# <decode-save> functions.
# 


# 3.52. count_alternatives
# 
# Type: boolean
# Default: no
# 
# When set, Mutt will recurse inside multipart/alternatives while performing
# attachment searching and counting (see attachments).
# 
# Traditionally, multipart/alternative parts have simply represented different
# encodings of the main content of the email. Unfortunately, some mail clients
# have started to place email attachments inside one of alternatives. Setting
# this will allow Mutt to find and count matching attachments hidden there, and
# include them in the index via %X or through ~X pattern matching.
# 


# 3.53. cursor_overlay
# 
# Type: boolean
# Default: no
# 
# When set, Mutt will overlay the indicator, tree, sidebar_highlight, and
# sidebar_indicator colors onto the currently selected line. This will allow
# default colors in those to be overridden, and for attributes to be merged
# between the layers.
# 


# 3.54. crypt_autoencrypt
# 
# Type: boolean
# Default: no
# 
# Setting this variable will cause Mutt to always attempt to PGP encrypt outgoing
# messages. This is probably only useful in connection to the “send-hook”
# command. It can be overridden by use of the pgp menu, when encryption is not
# required or signing is requested as well. If $smime_is_default is set, then
# OpenSSL is used instead to create S/MIME messages and settings can be
# overridden by use of the smime menu instead. (Crypto only)
# 


# 3.55. crypt_autopgp
# 
# Type: boolean
# Default: yes
# 
# This variable controls whether or not mutt may automatically enable PGP
# encryption/signing for messages. See also $crypt_autoencrypt,
# $crypt_replyencrypt, $crypt_autosign, $crypt_replysign and $smime_is_default.
# 


# 3.56. crypt_autosign
# 
# Type: boolean
# Default: no
# 
# Setting this variable will cause Mutt to always attempt to cryptographically
# sign outgoing messages. This can be overridden by use of the pgp menu, when
# signing is not required or encryption is requested as well. If
# $smime_is_default is set, then OpenSSL is used instead to create S/MIME
# messages and settings can be overridden by use of the smime menu instead of the
# pgp menu. (Crypto only)
# 
set crypt_autosign=no


# 3.57. crypt_autosmime
# 
# Type: boolean
# Default: yes
# 
# This variable controls whether or not mutt may automatically enable S/MIME
# encryption/signing for messages. See also $crypt_autoencrypt,
# $crypt_replyencrypt, $crypt_autosign, $crypt_replysign and $smime_is_default.
# 
set crypt_autosmime=no


# 3.58. crypt_confirmhook
# 
# Type: boolean
# Default: yes
# 
# If set, then you will be prompted for confirmation of keys when using the
# crypt-hook command. If unset, no such confirmation prompt will be presented.
# This is generally considered unsafe, especially where typos are concerned.
# 


# 3.59. crypt_opportunistic_encrypt
# 
# Type: boolean
# Default: no
# 
# Setting this variable will cause Mutt to automatically enable and disable
# encryption, based on whether all message recipient keys can be located by Mutt.
# 
# When this option is enabled, Mutt will enable/disable encryption each time the
# TO, CC, and BCC lists are edited. If $edit_headers is set, Mutt will also do so
# each time the message is edited.
# 
# While this is set, encryption can't be manually enabled/disabled. The pgp or
# smime menus provide a selection to temporarily disable this option for the
# current message.
# 
# If $crypt_autoencrypt or $crypt_replyencrypt enable encryption for a message,
# this option will be disabled for that message. It can be manually re-enabled in
# the pgp or smime menus. (Crypto only)
# 
set crypt_opportunistic_encrypt=no


# 3.60. crypt_opportunistic_encrypt_strong_keys
# 
# Type: boolean
# Default: no
# 
# When set, this modifies the behavior of $crypt_opportunistic_encrypt to only
# search for "strong keys", that is, keys with full validity according to the
# web-of-trust algorithm. A key with marginal or no validity will not enable
# opportunistic encryption.
# 
# For S/MIME, the behavior depends on the backend. Classic S/MIME will filter for
# certificates with the 't' (trusted) flag in the .index file. The GPGME backend
# will use the same filters as with OpenPGP, and depends on GPGME's logic for
# assigning the GPGME_VALIDITY_FULL and GPGME_VALIDITY_ULTIMATE validity flag.
# 


# 3.61. crypt_protected_headers_read
# 
# Type: boolean
# Default: yes
# 
# When set, Mutt will display protected headers in the pager, and will update the
# index and header cache with revised headers. Protected headers are stored
# inside the encrypted or signed part of an an email, to prevent disclosure or
# tampering. For more information see https://github.com/autocrypt/
# protected-headers. Currently Mutt only supports the Subject header.
# 
# Encrypted messages using protected headers often substitute the exposed Subject
# header with a dummy value (see $crypt_protected_headers_subject). Mutt will
# update its concept of the correct subject after the message is opened, i.e. via
# the <display-message> function. If you reply to a message before opening it,
# Mutt will end up using the dummy Subject header, so be sure to open such a
# message first. (Crypto only)
# 


# 3.62. crypt_protected_headers_save
# 
# Type: boolean
# Default: no
# 
# When $crypt_protected_headers_read is set, and a message with a protected
# Subject is opened, Mutt will save the updated Subject into the header cache by
# default. This allows searching/limiting based on the protected Subject header
# if the mailbox is re-opened, without having to re-open the message each time.
# However, for mbox/mh mailbox types, or if header caching is not set up, you
# would need to re-open the message each time the mailbox was reopened before you
# could see or search/limit on the protected subject again.
# 
# When this variable is set, Mutt additionally saves the protected Subject back
# in the clear-text message headers. This provides better usability, but with the
# tradeoff of reduced security. The protected Subject header, which may have
# previously been encrypted, is now stored in clear-text in the message headers.
# Copying the message elsewhere, via Mutt or external tools, could expose this
# previously encrypted data. Please make sure you understand the consequences of
# this before you enable this variable. (Crypto only)
# 


# 3.63. crypt_protected_headers_subject
# 
# Type: string
# Default: “...”
# 
# When $crypt_protected_headers_write is set, and the message is marked for
# encryption, this will be substituted into the Subject field in the message
# headers. To prevent a subject from being substituted, unset this variable, or
# set it to the empty string. (Crypto only)
# 


# 3.64. crypt_protected_headers_write
# 
# Type: boolean
# Default: no
# 
# When set, Mutt will generate protected headers for signed and encrypted emails.
# Protected headers are stored inside the encrypted or signed part of an an
# email, to prevent disclosure or tampering. For more information see https://
# github.com/autocrypt/protected-headers. Currently Mutt only supports the
# Subject header. (Crypto only)
# 


# 3.65. crypt_replyencrypt
# 
# Type: boolean
# Default: yes
# 
# If set, automatically PGP or OpenSSL encrypt replies to messages which are
# encrypted. (Crypto only)
# 


# 3.66. crypt_replysign
# 
# Type: boolean
# Default: no
# 
# If set, automatically PGP or OpenSSL sign replies to messages which are signed.
# 
# Note: this does not work on messages that are encrypted and signed! (Crypto
# only) 
# 
set crypt_replysign=yes


# 3.67. crypt_replysignencrypted
# 
# Type: boolean
# Default: no
# 
# If set, automatically PGP or OpenSSL sign replies to messages which are
# encrypted. This makes sense in combination with $crypt_replyencrypt, because it
# allows you to sign all messages which are automatically encrypted. This works
# around the problem noted in $crypt_replysign, that mutt is not able to find out
# whether an encrypted message is also signed. (Crypto only)
# 
set crypt_replysignencrypted=yes


# 3.68. crypt_timestamp
# 
# Type: boolean
# Default: yes
# 
# If set, mutt will include a time stamp in the lines surrounding PGP or S/MIME
# output, so spoofing such lines is more difficult. If you are using colors to
# mark these lines, and rely on these, you may unset this setting. (Crypto only)
# 


# 3.69. crypt_use_gpgme
# 
# Type: boolean
# Default: no
# 
# This variable controls the use of the GPGME-enabled crypto backends. If it is
# set and Mutt was built with gpgme support, the gpgme code for S/MIME and PGP
# will be used instead of the classic code. Note that you need to set this option
# in .muttrc; it won't have any effect when used interactively.
# 
# Note that the GPGME backend does not support creating old-style inline
# (traditional) PGP encrypted or signed messages (see $pgp_autoinline).
# 


# 3.70. crypt_use_pka
# 
# Type: boolean
# Default: no
# 
# Controls whether mutt uses PKA (see http://www.g10code.de/docs/
# pka-intro.de.pdf) during signature verification (only supported by the GPGME
# backend). 
# 
set crypt_use_pka=yes


# 3.71. crypt_verify_sig
# 
# Type: quadoption
# Default: yes
# 
# If “yes”, always attempt to verify PGP or S/MIME signatures. If “ask-*”, ask
# whether or not to verify the signature. If “no”, never attempt to verify
# cryptographic signatures. (Crypto only)
# 


# 3.72. date_format
# 
# Type: string
# Default: “!%a, %b %d, %Y at %I:%M:%S%p %Z”
# 
# This variable controls the format of the date printed by the “%d” sequence in
# $index_format. This is passed to the strftime(3) function to process the date,
# see the man page for the proper syntax.
# 
# Unless the first character in the string is a bang (“!”), the month and week
# day names are expanded according to the locale. If the first character in the
# string is a bang, the bang is discarded, and the month and week day names in
# the rest of the string are expanded in the C locale (that is in US English).
# 
set date_format="%F"


# 3.73. default_hook
# 
# Type: string
# Default: “~f %s !~P | (~P ~C %s)”
# 
# This variable controls how “message-hook”, “reply-hook”, “send-hook”, “
# send2-hook”, “save-hook”, and “fcc-hook” will be interpreted if they are
# specified with only a simple regexp, instead of a matching pattern. The hooks
# are expanded when they are declared, so a hook will be interpreted according to
# the value of this variable at the time the hook is declared.
# 
# The default value matches if the message is either from a user matching the
# regular expression given, or if it is from you (if the from address matches “
# alternates”) and is to or cc'ed to a user matching the given regular
# expression. 
# 


# 3.74. delete
# 
# Type: quadoption
# Default: ask-yes
# 
# Controls whether or not messages are really deleted when closing or
# synchronizing a mailbox. If set to yes, messages marked for deleting will
# automatically be purged without prompting. If set to no, messages marked for
# deletion will be kept in the mailbox.
# 
set delete=yes


# 3.75. delete_untag
# 
# Type: boolean
# Default: yes
# 
# If this option is set, mutt will untag messages when marking them for deletion.
# This applies when you either explicitly delete a message, or when you save it
# to another folder.
# 


# 3.76. digest_collapse
# 
# Type: boolean
# Default: yes
# 
# If this option is set, mutt's received-attachments menu will not show the
# subparts of individual messages in a multipart/digest. To see these subparts,
# press “v” on that menu.
# 


# 3.77. display_filter
# 
# Type: path
# Default: (empty)
# 
# When set, specifies a command used to filter messages. When a message is viewed
# it is passed as standard input to $display_filter, and the filtered message is
# read from the standard output.
# 


# 3.78. dotlock_program
# 
# Type: path
# Default: “/usr/bin/mutt_dotlock”
# 
# Contains the path of the mutt_dotlock(1) binary to be used by mutt.
# 


# 3.79. dsn_notify
# 
# Type: string
# Default: (empty)
# 
# This variable sets the request for when notification is returned. The string
# consists of a comma separated list (no spaces!) of one or more of the
# following: never, to never request notification, failure, to request
# notification on transmission failure, delay, to be notified of message delays,
# success, to be notified of successful transmission.
# 
# Example: 
# 
# set dsn_notify="failure,delay"
# 
# Note: when using $sendmail for delivery, you should not enable this unless you
# are either using Sendmail 8.8.x or greater or a MTA providing a sendmail(1)
# -compatible interface supporting the -N option for DSN. For SMTP delivery, DSN
# support is auto-detected so that it depends on the server whether DSN will be
# used or not.
# 


# 3.80. dsn_return
# 
# Type: string
# Default: (empty)
# 
# This variable controls how much of your message is returned in DSN messages. It
# may be set to either hdrs to return just the message header, or full to return
# the full message.
# 
# Example: 
# 
# set dsn_return=hdrs
# 
# Note: when using $sendmail for delivery, you should not enable this unless you
# are either using Sendmail 8.8.x or greater or a MTA providing a sendmail(1)
# -compatible interface supporting the -R option for DSN. For SMTP delivery, DSN
# support is auto-detected so that it depends on the server whether DSN will be
# used or not.
# 


# 3.81. duplicate_threads
# 
# Type: boolean
# Default: yes
# 
# This variable controls whether mutt, when $sort is set to threads, threads
# messages with the same Message-Id together. If it is set, it will indicate that
# it thinks they are duplicates of each other with an equals sign in the thread
# tree. 
# 


# 3.82. edit_headers
# 
# Type: boolean
# Default: no
# 
# This option allows you to edit the header of your outgoing messages along with
# the body of your message.
# 
# Although the compose menu may have localized header labels, the labels passed
# to your editor will be standard RFC 2822 headers, (e.g. To:, Cc:, Subject:).
# Headers added in your editor must also be RFC 2822 headers, or one of the
# pseudo headers listed in “edit-header”. Mutt will not understand localized
# header labels, just as it would not when parsing an actual email.
# 
# Note that changes made to the References: and Date: headers are ignored for
# interoperability reasons.
# 
set edit_headers=yes


# 3.83. editor
# 
# Type: path
# Default: (empty)
# 
# This variable specifies which editor is used by mutt. It defaults to the value
# of the $VISUAL, or $EDITOR, environment variable, or to the string “vi” if
# neither of those are set.
# 
# The $editor string may contain a %s escape, which will be replaced by the name
# of the file to be edited. If the %s escape does not appear in $editor, a space
# and the name to be edited are appended.
# 
# The resulting string is then executed by running
# 
# sh -c 'string'
# 
# where string is the expansion of $editor described above.
# 
set editor="mailplate --edit --auto --keep-unknown"


# 3.84. encode_from
# 
# Type: boolean
# Default: no
# 
# When set, mutt will quoted-printable encode messages when they contain the
# string “From ” (note the trailing space) in the beginning of a line. This is
# useful to avoid the tampering certain mail delivery and transport agents tend
# to do with messages (in order to prevent tools from misinterpreting the line as
# a mbox message separator).
# 


# 3.85. entropy_file
# 
# Type: path
# Default: (empty)
# 
# The file which includes random data that is used to initialize SSL library
# functions. 
# 


# 3.86. envelope_from_address
# 
# Type: e-mail address
# Default: (empty)
# 
# Manually sets the envelope sender for outgoing messages. This value is ignored
# if $use_envelope_from is unset.
# 


# 3.87. error_history
# 
# Type: number
# Default: 30
# 
# This variable controls the size (in number of strings remembered) of the error
# messages displayed by mutt. These can be shown with the <error-history>
# function. The history is cleared each time this variable is set.
# 


# 3.88. escape
# 
# Type: string
# Default: “~”
# 
# Escape character to use for functions in the built-in editor.
# 


# 3.89. fast_reply
# 
# Type: boolean
# Default: no
# 
# When set, the initial prompt for recipients and subject are skipped when
# replying to messages, and the initial prompt for subject is skipped when
# forwarding messages.
# 
# Note: this variable has no effect when the $autoedit variable is set.
# 


# 3.90. fcc_attach
# 
# Type: quadoption
# Default: yes
# 
# This variable controls whether or not attachments on outgoing messages are
# saved along with the main body of your message.
# 
# Note: $fcc_before_send forces the default (set) behavior of this option.
# 
set fcc_attach=yes


# 3.91. fcc_before_send
# 
# Type: boolean
# Default: no
# 
# When this variable is set, FCCs will occur before sending the message. Before
# sending, the message cannot be manipulated, so it will be stored the exact same
# as sent: $fcc_attach and $fcc_clear will be ignored (using their default
# values). 
# 
# When unset, the default, FCCs will occur after sending. Variables $fcc_attach
# and $fcc_clear will be respected, allowing it to be stored without attachments
# or encryption/signing if desired.
# 


# 3.92. fcc_clear
# 
# Type: boolean
# Default: no
# 
# When this variable is set, FCCs will be stored unencrypted and unsigned, even
# when the actual message is encrypted and/or signed.
# 
# Note: $fcc_before_send forces the default (unset) behavior of this option. (PGP
# only) 
# 
# See also $pgp_self_encrypt, $smime_self_encrypt.
# 


# 3.93. fcc_delimiter
# 
# Type: string
# Default: (empty)
# 
# When specified, this allows the ability to Fcc to more than one mailbox. The
# fcc value will be split by this delimiter and Mutt will evaluate each part as a
# mailbox separately.
# 
# See $record, “fcc-hook”, and “fcc-save-hook”.
# 


# 3.94. flag_safe
# 
# Type: boolean
# Default: no
# 
# If set, flagged messages cannot be deleted.
# 


# 3.95. folder
# 
# Type: path
# Default: “~/Mail”
# 
# Specifies the default location of your mailboxes. A “+” or “=” at the beginning
# of a pathname will be expanded to the value of this variable. Note that if you
# change this variable (from the default) value you need to make sure that the
# assignment occurs before you use “+” or “=” for any other variables since
# expansion takes place when handling the “mailboxes” command.
# 
set folder="~/mail"


# 3.96. folder_format
# 
# Type: string
# Default: “%2C %t %N %F %2l %-8.8u %-8.8g %8s %d %f”
# 
# This variable allows you to customize the file browser display to your personal
# taste. This string is similar to $index_format, but has its own set of printf
# (3)-like sequences:
#

# 
set folder_format='%t%N%2C  %D  %4s  %f'


# 3.97. followup_to
# 
# Type: boolean
# Default: yes
# 
# Controls whether or not the “Mail-Followup-To:” header field is generated when
# sending mail. When set, Mutt will generate this field when you are replying to
# a known mailing list, specified with the “subscribe” or “lists” commands.
# 
# This field has two purposes. First, preventing you from receiving duplicate
# copies of replies to messages which you send to mailing lists, and second,
# ensuring that you do get a reply separately for any messages sent to known
# lists to which you are not subscribed.
# 
# The header will contain only the list's address for subscribed lists, and both
# the list address and your own email address for unsubscribed lists. Without
# this header, a group reply to your message sent to a subscribed list will be
# sent to both the list and your address, resulting in two copies of the same
# email for you.
# 


# 3.98. force_name
# 
# Type: boolean
# Default: no
# 
# This variable is similar to $save_name, except that Mutt will store a copy of
# your outgoing message by the username of the address you are sending to even if
# that mailbox does not exist.
# 
# Also see the $record variable.
# 


# 3.99. forward_attachments
# 
# Type: quadoption
# Default: ask-yes
# 
# When forwarding inline (i.e. $mime_forward unset or answered with “no” and
# $forward_decode set), attachments which cannot be decoded in a reasonable
# manner will be attached to the newly composed message if this quadoption is set
# or answered with “yes”.
# 


# 3.100. forward_attribution_intro
# 
# Type: string (localized)
# Default: “----- Forwarded message from %f -----”
# 
# This is the string that will precede a message which has been forwarded in the
# main body of a message (when $mime_forward is unset). For a full listing of
# defined printf(3)-like sequences see the section on $index_format. See also
# $attribution_locale. 
# 


# 3.101. forward_attribution_trailer
# 
# Type: string (localized)
# Default: “----- End forwarded message -----”
# 
# This is the string that will follow a message which has been forwarded in the
# main body of a message (when $mime_forward is unset). For a full listing of
# defined printf(3)-like sequences see the section on $index_format. See also
# $attribution_locale. 
# 


# 3.102. forward_decode
# 
# Type: boolean
# Default: yes
# 
# Controls the decoding of complex MIME messages into text/plain when forwarding
# a message. The message header is also RFC2047 decoded. This variable is only
# used, if $mime_forward is unset, otherwise $mime_forward_decode is used
# instead. 
# 


# 3.103. forward_decrypt
# 
# Type: quadoption
# Default: yes
# 
# This quadoption controls the handling of encrypted messages when forwarding or
# attaching a message. When set to or answered “yes”, the outer layer of
# encryption is stripped off.
# 
# This variable is used if $mime_forward is set and $mime_forward_decode is unset
# . It is also used when attaching a message via <attach-message> in the compose
# menu. (PGP only)
# 


# 3.104. forward_edit
# 
# Type: quadoption
# Default: yes
# 
# This quadoption controls whether or not the user is automatically placed in the
# editor when forwarding messages. For those who always want to forward with no
# modification, use a setting of “no”.
# 


# 3.105. forward_format
# 
# Type: string
# Default: “[%a: %s]”
# 
# This variable controls the default subject when forwarding a message. It uses
# the same format sequences as the $index_format variable.
# 
set forward_format="(fwd) %s"


# 3.106. forward_quote
# 
# Type: boolean
# Default: no
# 
# When set, forwarded messages included in the main body of the message (when
# $mime_forward is unset) will be quoted using $indent_string.
# 


# 3.107. from
# 
# Type: e-mail address
# Default: (empty)
# 
# When set, this variable contains a default from address. It can be overridden
# using “my_hdr” (including from a “send-hook”) and $reverse_name. This variable
# is ignored if $use_from is unset.
# 
# This setting defaults to the contents of the environment variable $EMAIL.
# 
set from='martin f krafft <madduck@madduck.net>'


# 3.108. gecos_mask
# 
# Type: regular expression
# Default: “^[^,]*”
# 
# A regular expression used by mutt to parse the GECOS field of a password entry
# when expanding the alias. The default value will return the string up to the
# first “,” encountered. If the GECOS field contains a string like “lastname,
# firstname” then you should set it to “.*”.
# 
# This can be useful if you see the following behavior: you address an e-mail to
# user ID “stevef” whose full name is “Steve Franklin”. If mutt expands “stevef”
# to “"Franklin" stevef@foo.bar” then you should set the $gecos_mask to a regular
# expression that will match the whole name so mutt will expand “Franklin” to “
# Franklin, Steve”.
# 


# 3.109. hdrs
# 
# Type: boolean
# Default: yes
# 
# When unset, the header fields normally added by the “my_hdr” command are not
# created. This variable must be unset before composing a new message or replying
# in order to take effect. If set, the user defined header fields are added to
# every new message.
# 


# 3.110. header
# 
# Type: boolean
# Default: no
# 
# When set, this variable causes Mutt to include the header of the message you
# are replying to into the edit buffer. The $weed setting applies.
# 


# 3.111. header_cache
# 
# Type: path
# Default: (empty)
# 
# This variable points to the header cache database. If pointing to a directory
# Mutt will contain a header cache database file per folder, if pointing to a
# file that file will be a single global header cache. By default it is unset so
# no header caching will be used.
# 
# Header caching can greatly improve speed when opening POP, IMAP MH or Maildir
# folders, see “caching” for details.
# 
set header_cache="~/.var/mutt/header_cache"


# 3.112. header_cache_compress
# 
# Type: boolean
# Default: yes
# 
# When mutt is compiled with qdbm, tokyocabinet, or kyotocabinet as header cache
# backend, this option determines whether the database will be compressed.
# Compression results in database files roughly being one fifth of the usual
# diskspace, but the decompression can result in a slower opening of cached
# folder(s) which in general is still much faster than opening non header cached
# folders. 
# 
set header_cache_compress=no


# 3.113. header_cache_pagesize
# 
# Type: number (long)
# Default: 16384
# 
# When mutt is compiled with either gdbm or bdb4 as the header cache backend,
# this option changes the database page size. Too large or too small values can
# waste space, memory, or CPU time. The default should be more or less optimal
# for most use cases.
# 


# 3.114. header_color_partial
# 
# Type: boolean
# Default: no
# 
# When set, color header regexps behave like color body regexps: color is applied
# to the exact text matched by the regexp. When unset, color is applied to the
# entire header.
# 
# One use of this option might be to apply color to just the header labels.
# 
# See “color” for more details.
# 


# 3.115. help
# 
# Type: boolean
# Default: yes
# 
# When set, help lines describing the bindings for the major functions provided
# by each menu are displayed on the first line of the screen.
# 
# Note: The binding will not be displayed correctly if the function is bound to a
# sequence rather than a single keystroke. Also, the help line may not be updated
# if a binding is changed while Mutt is running. Since this variable is primarily
# aimed at new users, neither of these should present a major problem.
# 


# 3.116. hidden_host
# 
# Type: boolean
# Default: no
# 
# When set, mutt will skip the host name part of $hostname variable when adding
# the domain part to addresses. This variable does not affect the generation of
# Message-IDs, and it will not lead to the cut-off of first-level domains.
# 


# 3.117. hide_limited
# 
# Type: boolean
# Default: no
# 
# When set, mutt will not show the presence of messages that are hidden by
# limiting, in the thread tree.
# 


# 3.118. hide_missing
# 
# Type: boolean
# Default: yes
# 
# When set, mutt will not show the presence of missing messages in the thread
# tree. 
# 


# 3.119. hide_thread_subject
# 
# Type: boolean
# Default: yes
# 
# When set, mutt will not show the subject of messages in the thread tree that
# have the same subject as their parent or closest previously displayed sibling.
# 


# 3.120. hide_top_limited
# 
# Type: boolean
# Default: no
# 
# When set, mutt will not show the presence of messages that are hidden by
# limiting, at the top of threads in the thread tree. Note that when
# $hide_limited is set, this option will have no effect.
# 


# 3.121. hide_top_missing
# 
# Type: boolean
# Default: yes
# 
# When set, mutt will not show the presence of missing messages at the top of
# threads in the thread tree. Note that when $hide_missing is set, this option
# will have no effect.
# 


# 3.122. history
# 
# Type: number
# Default: 10
# 
# This variable controls the size (in number of strings remembered) of the string
# history buffer per category. The buffer is cleared each time the variable is
# set. 
# 


# 3.123. history_file
# 
# Type: path
# Default: “~/.mutthistory”
# 
# The file in which Mutt will save its history.
# 
# Also see $save_history.
# 
set history_file="~/.var/mutt/history"


# 3.124. history_remove_dups
# 
# Type: boolean
# Default: no
# 
# When set, all of the string history will be scanned for duplicates when a new
# entry is added. Duplicate entries in the $history_file will also be removed
# when it is periodically compacted.
# 


# 3.125. honor_disposition
# 
# Type: boolean
# Default: no
# 
# When set, Mutt will not display attachments with a disposition of “attachment”
# inline even if it could render the part to plain text. These MIME parts can
# only be viewed from the attachment menu.
# 
# If unset, Mutt will render all MIME parts it can properly transform to plain
# text. 
# 


# 3.126. honor_followup_to
# 
# Type: quadoption
# Default: yes
# 
# This variable controls whether or not a Mail-Followup-To header is honored when
# group-replying to a message.
# 


# 3.127. hostname
# 
# Type: string
# Default: (empty)
# 
# Specifies the fully-qualified hostname of the system mutt is running on
# containing the host's name and the DNS domain it belongs to. It is used as the
# domain part (after “@”) for local email addresses as well as Message-Id
# headers. 
# 
# Its value is determined at startup as follows: the node's hostname is first
# determined by the uname(3) function. The domain is then looked up using the
# gethostname(2) and getaddrinfo(3) functions. If those calls are unable to
# determine the domain, the full value returned by uname is used. Optionally,
# Mutt can be compiled with a fixed domain name in which case a detected one is
# not used.
# 
# Starting in Mutt 2.0, the operations described in the previous paragraph are
# performed after the muttrc is processed, instead of beforehand. This way, if
# the DNS operations are creating delays at startup, you can avoid those by
# manually setting the value in your muttrc.
# 
# Also see $use_domain and $hidden_host.
# 


# 3.128. idn_decode
# 
# Type: boolean
# Default: yes
# 
# When set, Mutt will show you international domain names decoded. Note: You can
# use IDNs for addresses even if this is unset. This variable only affects
# decoding. (IDN only)
# 


# 3.129. idn_encode
# 
# Type: boolean
# Default: yes
# 
# When set, Mutt will encode international domain names using IDN. Unset this if
# your SMTP server can handle newer (RFC 6531) UTF-8 encoded domains. (IDN only)
# 


# 3.130. ignore_linear_white_space
# 
# Type: boolean
# Default: no
# 
# This option replaces linear-white-space between encoded-word and text to a
# single space to prevent the display of MIME-encoded “Subject:” field from being
# divided into multiple lines.
# 


# 3.131. ignore_list_reply_to
# 
# Type: boolean
# Default: no
# 
# Affects the behavior of the <reply> function when replying to messages from
# mailing lists (as defined by the “subscribe” or “lists” commands). When set, if
# the “Reply-To:” field is set to the same value as the “To:” field, Mutt assumes
# that the “Reply-To:” field was set by the mailing list to automate responses to
# the list, and will ignore this field. To direct a response to the mailing list
# when this option is set, use the <list-reply> function; <group-reply> will
# reply to both the sender and the list.
# 
set ignore_list_reply_to=yes


# 3.132. imap_authenticators
# 
# Type: string
# Default: (empty)
# 
# This is a colon-delimited list of authentication methods mutt may attempt to
# use to log in to an IMAP server, in the order mutt should try them.
# Authentication methods are either “login” or the right side of an IMAP “AUTH=
# xxx” capability string, e.g. “digest-md5”, “gssapi” or “cram-md5”. This option
# is case-insensitive. If it's unset (the default) mutt will try all available
# methods, in order from most-secure to least-secure.
# 
# Example: 
# 
# set imap_authenticators="gssapi:cram-md5:login"
# 
# Note: Mutt will only fall back to other authentication methods if the previous
# methods are unavailable. If a method is available but authentication fails,
# mutt will not connect to the IMAP server.
# 


# 3.133. imap_check_subscribed
# 
# Type: boolean
# Default: no
# 
# When set, mutt will fetch the set of subscribed folders from your server on
# connection, and add them to the set of mailboxes it polls for new mail just as
# if you had issued individual “mailboxes” commands.
# 


# 3.134. imap_condstore
# 
# Type: boolean
# Default: no
# 
# When set, mutt will use the CONDSTORE extension (RFC 7162) if advertised by the
# server. Mutt's current implementation is basic, used only for initial message
# fetching and flag updates.
# 
# For some IMAP servers, enabling this will slightly speed up downloading initial
# messages. Unfortunately, Gmail is not one those, and displays worse performance
# when enabled. Your mileage may vary.
# 


# 3.135. imap_deflate
# 
# Type: boolean
# Default: no
# 
# When set, mutt will use the COMPRESS=DEFLATE extension (RFC 4978) if advertised
# by the server.
# 
# In general a good compression efficiency can be achieved, which speeds up
# reading large mailboxes also on fairly good connections.
# 


# 3.136. imap_delim_chars
# 
# Type: string
# Default: “/.”
# 
# This contains the list of characters which you would like to treat as folder
# separators for displaying IMAP paths. In particular it helps in using the “=”
# shortcut for your folder variable.
# 


# 3.137. imap_fetch_chunk_size
# 
# Type: number (long)
# Default: 0
# 
# When set to a value greater than 0, new headers will be downloaded in groups of
# this many headers per request. If you have a very large mailbox, this might
# prevent a timeout and disconnect when opening the mailbox, by sending a FETCH
# per set of this many headers, instead of a single FETCH for all new headers.
# 


# 3.138. imap_headers
# 
# Type: string
# Default: (empty)
# 
# Mutt requests these header fields in addition to the default headers (“Date:”,
# “From:”, “Sender:”, “Subject:”, “To:”, “Cc:”, “Message-Id:”, “References:”, “
# Content-Type:”, “Content-Description:”, “In-Reply-To:”, “Reply-To:”, “Lines:”,
# “List-Post:”, “X-Label:”) from IMAP servers before displaying the index menu.
# You may want to add more headers for spam detection.
# 
# Note: This is a space separated list, items should be uppercase and not contain
# the colon, e.g. “X-BOGOSITY X-SPAM-STATUS” for the “X-Bogosity:” and “
# X-Spam-Status:” header fields.
# 


# 3.139. imap_idle
# 
# Type: boolean
# Default: no
# 
# When set, mutt will attempt to use the IMAP IDLE extension to check for new
# mail in the current mailbox. Some servers (dovecot was the inspiration for this
# option) react badly to mutt's implementation. If your connection seems to
# freeze up periodically, try unsetting this.
# 


# 3.140. imap_keepalive
# 
# Type: number
# Default: 300
# 
# This variable specifies the maximum amount of time in seconds that mutt will
# wait before polling open IMAP connections, to prevent the server from closing
# them before mutt has finished with them. The default is well within the
# RFC-specified minimum amount of time (30 minutes) before a server is allowed to
# do this, but in practice the RFC does get violated every now and then. Reduce
# this number if you find yourself getting disconnected from your IMAP server due
# to inactivity.
# 


# 3.141. imap_list_subscribed
# 
# Type: boolean
# Default: no
# 
# This variable configures whether IMAP folder browsing will look for only
# subscribed folders or all folders. This can be toggled in the IMAP browser with
# the <toggle-subscribed> function.
# 


# 3.142. imap_login
# 
# Type: string
# Default: (empty)
# 
# Your login name on the IMAP server.
# 
# This variable defaults to the value of $imap_user.
# 


# 3.143. imap_oauth_refresh_command
# 
# Type: string
# Default: (empty)
# 
# The command to run to generate an OAUTH refresh token for authorizing your
# connection to your IMAP server. This command will be run on every connection
# attempt that uses the OAUTHBEARER authentication mechanism. See “oauth” for
# details. 
# 


# 3.144. imap_pass
# 
# Type: string
# Default: (empty)
# 
# Specifies the password for your IMAP account. If unset, Mutt will prompt you
# for your password when you invoke the <imap-fetch-mail> function or try to open
# an IMAP folder.
# 
# Warning: you should only use this option when you are on a fairly secure
# machine, because the superuser can read your muttrc even if you are the only
# one who can read the file.
# 


# 3.145. imap_passive
# 
# Type: boolean
# Default: yes
# 
# When set, mutt will not open new IMAP connections to check for new mail. Mutt
# will only check for new mail over existing IMAP connections. This is useful if
# you don't want to be prompted for user/password pairs on mutt invocation, or if
# opening the connection is slow.
# 


# 3.146. imap_peek
# 
# Type: boolean
# Default: yes
# 
# When set, mutt will avoid implicitly marking your mail as read whenever you
# fetch a message from the server. This is generally a good thing, but can make
# closing an IMAP folder somewhat slower. This option exists to appease speed
# freaks. 
# 


# 3.147. imap_pipeline_depth
# 
# Type: number
# Default: 15
# 
# Controls the number of IMAP commands that may be queued up before they are sent
# to the server. A deeper pipeline reduces the amount of time mutt must wait for
# the server, and can make IMAP servers feel much more responsive. But not all
# servers correctly handle pipelined commands, so if you have problems you might
# want to try setting this variable to 0.
# 
# Note: Changes to this variable have no effect on open connections.
# 


# 3.148. imap_poll_timeout
# 
# Type: number
# Default: 15
# 
# This variable specifies the maximum amount of time in seconds that mutt will
# wait for a response when polling IMAP connections for new mail, before timing
# out and closing the connection. Set to 0 to disable timing out.
# 


# 3.149. imap_qresync
# 
# Type: boolean
# Default: no
# 
# When set, mutt will use the QRESYNC extension (RFC 7162) if advertised by the
# server. Mutt's current implementation is basic, used only for initial message
# fetching and flag updates.
# 
# Note: this feature is currently experimental. If you experience strange
# behavior, such as duplicate or missing messages please file a bug report to let
# us know.
# 


# 3.150. imap_servernoise
# 
# Type: boolean
# Default: yes
# 
# When set, mutt will display warning messages from the IMAP server as error
# messages. Since these messages are often harmless, or generated due to
# configuration problems on the server which are out of the users' hands, you may
# wish to suppress them at some point.
# 


# 3.151. imap_user
# 
# Type: string
# Default: (empty)
# 
# The name of the user whose mail you intend to access on the IMAP server.
# 
# This variable defaults to your user name on the local machine.
# 


# 3.152. implicit_autoview
# 
# Type: boolean
# Default: no
# 
# If set to “yes”, mutt will look for a mailcap entry with the “copiousoutput”
# flag set for every MIME attachment it doesn't have an internal viewer defined
# for. If such an entry is found, mutt will use the viewer defined in that entry
# to convert the body part to text form.
# 
set implicit_autoview=no


# 3.153. include
# 
# Type: quadoption
# Default: ask-yes
# 
# Controls whether or not a copy of the message(s) you are replying to is
# included in your reply.
# 
set include=yes


# 3.154. include_encrypted
# 
# Type: boolean
# Default: no
# 
# Controls whether or not Mutt includes separately encrypted attachment contents
# when replying.
# 
# This variable was added to prevent accidental exposure of encrypted contents
# when replying to an attacker. If a previously encrypted message were attached
# by the attacker, they could trick an unwary recipient into decrypting and
# including the message in their reply.
# 


# 3.155. include_onlyfirst
# 
# Type: boolean
# Default: no
# 
# Controls whether or not Mutt includes only the first attachment of the message
# you are replying.
# 


# 3.156. indent_string
# 
# Type: string
# Default: “> ”
# 
# Specifies the string to prepend to each line of text quoted in a message to
# which you are replying. You are strongly encouraged not to change this value,
# as it tends to agitate the more fanatical netizens.
# 
# The value of this option is ignored if $text_flowed is set, because the quoting
# mechanism is strictly defined for format=flowed.
# 
# This option is a format string, please see the description of $index_format for
# supported printf(3)-style sequences.
# 


# 3.157. index_format
# 
# Type: string
# Default: “%4C %Z %{%b %d} %-15.15L (%?l?%4l&%4c?) %s”
# 
# This variable allows you to customize the message index display to your
# personal taste.
# 
# “Format strings” are similar to the strings used in the C function printf(3) to
# format output (see the man page for more details). For an explanation of the %?
# construct, see the $status_format description. The following sequences are
# defined in Mutt:
# 
# ┌───────┬─────────────────────────────────────────────────────────────────────┐ 
# │%a │address of the author                                                │

# ├───────┼─────────────────────────────────────────────────────────────────────┤ 
# │ │If an address in the “To:” or “Cc:” header field matches an address  │

# the different parts of the message and has little meaning in practice.
# 
# “Soft-fill” deserves some explanation: Normal right-justification will print
# everything to the left of the “%>”, displaying padding and whatever lies to the
# right only if there's room. By contrast, soft-fill gives priority to the
# right-hand side, guaranteeing space to display it and showing padding only if
# there's still room. If necessary, soft-fill will eat text leftwards to make
# room for rightward text.

# 


# 3.158. ispell
# 
# Type: path
# Default: “ispell”
# 
# How to invoke ispell (GNU's spell-checking software).
# 


# 3.159. keep_flagged
# 
# Type: boolean
# Default: no
# 
# If set, read messages marked as flagged will not be moved from your spool
# mailbox to your $mbox mailbox, or as a result of a “mbox-hook” command.
# 


# 3.160. local_date_header
# 
# Type: boolean
# Default: yes
# 
# If set, convert the date in the Date header of sent emails into local
# (sender's) timezone.
# 


# 3.161. mail_check
# 
# Type: number
# Default: 5
# 
# This variable configures how often (in seconds) mutt should look for new mail.
# Also see the $timeout variable.
# 


# 3.162. mail_check_recent
# 
# Type: boolean
# Default: yes
# 
# When set, Mutt will only notify you about new mail that has been received since
# the last time you opened the mailbox. When unset, Mutt will notify you if any
# new mail exists in the mailbox, regardless of whether you have visited it
# recently. 
# 
# When $mark_old is set, Mutt does not consider the mailbox to contain new mail
# if only old messages exist.
# 


# 3.163. mail_check_stats
# 
# Type: boolean
# Default: no
# 
# When set, mutt will periodically calculate message statistics of a mailbox
# while polling for new mail. It will check for unread, flagged, and total
# message counts. Because this operation is more performance intensive, it
# defaults to unset, and has a separate option, $mail_check_stats_interval, to
# control how often to update these counts.
# 
# Message statistics can also be explicitly calculated by invoking the
# <check-stats> function.
# 
set mail_check_stats=yes


# 3.164. mail_check_stats_interval
# 
# Type: number
# Default: 60
# 
# When $mail_check_stats is set, this variable configures how often (in seconds)
# mutt will update message counts.
# 


# 3.165. mailcap_path
# 
# Type: string
# Default: (empty)
# 
# This variable specifies which files to consult when attempting to display MIME
# bodies not directly supported by Mutt. The default value is generated during
# startup: see the “mailcap” section of the manual.
# 
set mailcap_path="$my_confdir/mailcap.containers:$my_confdir/mailcap.icalendar:$my_confdir/mailcap.backgrounding:$my_confdir/mailcap.htmldump"


# 3.166. mailcap_sanitize
# 
# Type: boolean
# Default: yes
# 
# If set, mutt will restrict possible characters in mailcap % expandos to a
# well-defined set of safe characters. This is the safe setting, but we are not
# sure it doesn't break some more advanced MIME stuff.
# 
# DON'T CHANGE THIS SETTING UNLESS YOU ARE REALLY SURE WHAT YOU ARE DOING!
# 


# 3.167. maildir_header_cache_verify
# 
# Type: boolean
# Default: yes
# 
# Check for Maildir unaware programs other than mutt having modified maildir
# files when the header cache is in use. This incurs one stat(2) per message
# every time the folder is opened (which can be very slow for NFS folders).
# 
set maildir_header_cache_verify=no


# 3.168. maildir_trash
# 
# Type: boolean
# Default: no
# 
# If set, messages marked as deleted will be saved with the maildir trashed flag
# instead of unlinked. Note: this only applies to maildir-style mailboxes.
# Setting it will have no effect on other mailbox types.
# 


# 3.169. maildir_check_cur
# 
# Type: boolean
# Default: no
# 
# If set, mutt will poll both the new and cur directories of a maildir folder for
# new messages. This might be useful if other programs interacting with the
# folder (e.g. dovecot) are moving new messages to the cur directory. Note that
# setting this option may slow down polling for new messages in large folders,
# since mutt has to scan all cur messages.
# 


# 3.170. mark_macro_prefix
# 
# Type: string
# Default: “'”
# 
# Prefix for macros created using mark-message. A new macro automatically
# generated with <mark-message>a will be composed from this prefix and the letter
# a. 
# 


# 3.171. mark_old
# 
# Type: boolean
# Default: yes
# 
# Controls whether or not mutt marks new unread messages as old if you exit a
# mailbox without reading them. With this option set, the next time you start
# mutt, the messages will show up with an “O” next to them in the index menu,
# indicating that they are old.
# 
set mark_old=no


# 3.172. markers
# 
# Type: boolean
# Default: yes
# 
# Controls the display of wrapped lines in the internal pager. If set, a “+”
# marker is displayed at the beginning of wrapped lines.
# 
# Also see the $smart_wrap variable.
# 
set markers=no


# 3.173. mask
# 
# Type: regular expression
# Default: “!^.[^.]”
# 
# A regular expression used in the file browser, optionally preceded by the not
# operator “!”. Only files whose names match this mask will be shown. The match
# is always case-sensitive.
# 


# 3.174. mbox
# 
# Type: path
# Default: “~/mbox”
# 
# This specifies the folder into which read mail in your $spoolfile folder will
# be appended.
# 
# Also see the $move variable.
# 
set mbox="=spool"


# 3.175. mbox_type
# 
# Type: folder magic
# Default: mbox
# 
# The default mailbox type used when creating new folders. May be any of “mbox”,
# “MMDF”, “MH” and “Maildir”. This is overridden by the -m command-line option.
# 
set mbox_type=Maildir


# 3.176. menu_context
# 
# Type: number
# Default: 0
# 
# This variable controls the number of lines of context that are given when
# scrolling through menus. (Similar to $pager_context.)
# 
set menu_context=5


# 3.177. menu_move_off
# 
# Type: boolean
# Default: yes
# 
# When unset, the bottom entry of menus will never scroll up past the bottom of
# the screen, unless there are less entries than lines. When set, the bottom
# entry may move off the bottom.
# 


# 3.178. menu_scroll
# 
# Type: boolean
# Default: no
# 
# When set, menus will be scrolled up or down one line when you attempt to move
# across a screen boundary. If unset, the screen is cleared and the next or
# previous page of the menu is displayed (useful for slow links to avoid many
# redraws). 
# 
set menu_scroll=yes


# 3.179. message_cache_clean
# 
# Type: boolean
# Default: no
# 
# If set, mutt will clean out obsolete entries from the message cache when the
# mailbox is synchronized. You probably only want to set it every once in a
# while, since it can be a little slow (especially for large folders).
# 


# 3.180. message_cachedir
# 
# Type: path
# Default: (empty)
# 
# Set this to a directory and mutt will cache copies of messages from your IMAP
# and POP servers here. You are free to remove entries at any time.
# 
# When setting this variable to a directory, mutt needs to fetch every remote
# message only once and can perform regular expression searches as fast as for
# local folders.
# 
# Also see the $message_cache_clean variable.
# 


# 3.181. message_format
# 
# Type: string
# Default: “%s”
# 
# This is the string displayed in the “attachment” menu for attachments of type
# message/rfc822. For a full listing of defined printf(3)-like sequences see the
# section on $index_format.
# 


# 3.182. message_id_format
# 
# Type: string
# Default: “<%z@%f>”
# 
# This variable describes the format of the Message-ID generated when sending
# messages. Mutt 2.0 introduced a more compact format, but this variable allows
# the ability to choose your own format. The value may end in “|” to invoke an
# external filter. See formatstrings-filters.
# 
# Please note that the Message-ID value follows a strict syntax, and you are
# responsible for ensuring correctness if you change this from the default. In
# particular, the value must follow the syntax in RFC 5322: “"<" id-left "@"
# id-right ">"”. No spaces are allowed, and id-left should follow the
# dot-atom-text syntax in the RFC. The id-right should generally be left at %f.
# 
# The old Message-ID format can be used by setting this to: “
# <%Y%02m%02d%02H%02M%02S.G%c%p@%f>” 
# 
# The following printf(3)-style sequences are understood:

# └──┴─────────────────────────────────────────────────────────────────┘ 
# 


# 3.183. meta_key
# 
# Type: boolean
# Default: no
# 
# If set, forces Mutt to interpret keystrokes with the high bit (bit 8) set as if
# the user had pressed the Esc key and whatever key remains after having the high
# bit removed. For example, if the key pressed has an ASCII value of 0xf8, then
# this is treated as if the user had pressed Esc then “x”. This is because the
# result of removing the high bit from 0xf8 is 0x78, which is the ASCII character
# “x”. 
# 


# 3.184. metoo
# 
# Type: boolean
# Default: no
# 
# If unset, Mutt will remove your address (see the “alternates” command) from the
# list of recipients when replying to a message.
# 


# 3.185. mh_purge
# 
# Type: boolean
# Default: no
# 
# When unset, mutt will mimic mh's behavior and rename deleted messages to ,<old
# file name> in mh folders instead of really deleting them. This leaves the
# message on disk but makes programs reading the folder ignore it. If the
# variable is set, the message files will simply be deleted.
# 
# This option is similar to $maildir_trash for Maildir folders.
# 


# 3.186. mh_seq_flagged
# 
# Type: string
# Default: “flagged”
# 
# The name of the MH sequence used for flagged messages.
# 


# 3.187. mh_seq_replied
# 
# Type: string
# Default: “replied”
# 
# The name of the MH sequence used to tag replied messages.
# 


# 3.188. mh_seq_unseen
# 
# Type: string
# Default: “unseen”
# 
# The name of the MH sequence used for unseen messages.
# 


# 3.189. mime_forward
# 
# Type: quadoption
# Default: no
# 
# When set, the message you are forwarding will be attached as a separate message
# /rfc822 MIME part instead of included in the main body of the message. This is
# useful for forwarding MIME messages so the receiver can properly view the
# message as it was delivered to you. If you like to switch between MIME and not
# MIME from mail to mail, set this variable to “ask-no” or “ask-yes”.
# 
# Also see $forward_decode and $mime_forward_decode.
# 
set mime_forward=ask-yes


# 3.190. mime_forward_decode
# 
# Type: boolean
# Default: no
# 
# Controls the decoding of complex MIME messages into text/plain when forwarding
# a message while $mime_forward is set. Otherwise $forward_decode is used
# instead. 
# 


# 3.191. mime_forward_rest
# 
# Type: quadoption
# Default: yes
# 
# When forwarding multiple attachments of a MIME message from the attachment
# menu, attachments which cannot be decoded in a reasonable manner will be
# attached to the newly composed message if this option is set.
# 


# 3.192. mime_type_query_command
# 
# Type: string
# Default: (empty)
# 
# This specifies a command to run, to determine the mime type of a new attachment
# when composing a message. Unless $mime_type_query_first is set, this will only
# be run if the attachment's extension is not found in the mime.types file.
# 
# The string may contain a “%s”, which will be substituted with the attachment
# filename. Mutt will add quotes around the string substituted for “%s”
# automatically according to shell quoting rules, so you should avoid adding your
# own. If no “%s” is found in the string, Mutt will append the attachment
# filename to the end of the string.
# 
# The command should output a single line containing the attachment's mime type.
# 
# Suggested values are “xdg-mime query filetype” or “file -bi”.
# 


# 3.193. mime_type_query_first
# 
# Type: boolean
# Default: no
# 
# When set, the $mime_type_query_command will be run before the mime.types
# lookup. 
# 


# 3.194. mix_entry_format
# 
# Type: string
# Default: “%4n %c %-16s %a”
# 
# This variable describes the format of a remailer line on the mixmaster chain
# selection screen. The following printf(3)-like sequences are supported:
# 
# ┌──┬───────────────────────────────┐ 
# │%n│The running number on the menu.│
# ├──┼───────────────────────────────┤ 
# │%c│Remailer capabilities.         │

# │%a│The remailer's e-mail address. │
# └──┴───────────────────────────────┘ 
# 


# 3.195. mixmaster
# 
# Type: path
# Default: “mixmaster”
# 
# This variable contains the path to the Mixmaster binary on your system. It is
# used with various sets of parameters to gather the list of known remailers, and
# to finally send a message through the mixmaster chain.
# 
set mixmaster="mixmaster-filter"


# 3.196. move
# 
# Type: quadoption
# Default: no
# 
# Controls whether or not Mutt will move read messages from your spool mailbox to
# your $mbox mailbox, or as a result of a “mbox-hook” command.
# 
set move=no


# 3.197. muttlisp_inline_eval
# 
# Type: boolean
# Default: no
# 
# If set, Mutt will evaluate bare parenthesis arguments to commands as MuttLisp
# expressions. 
# 


# 3.198. narrow_tree
# 
# Type: boolean
# Default: no
# 
# This variable, when set, makes the thread tree narrower, allowing deeper
# threads to fit on the screen.
# 
set narrow_tree=yes


# 3.199. net_inc
# 
# Type: number
# Default: 10
# 
# Operations that expect to transfer a large amount of data over the network will
# update their progress every $net_inc kilobytes. If set to 0, no progress
# messages will be displayed.
# 
# See also $read_inc, $write_inc and $net_inc.
# 


# 3.200. new_mail_command
# 
# Type: path
# Default: (empty)
# 
# If set, Mutt will call this command after a new message is received. See the
# $status_format documentation for the values that can be formatted into this
# command. 
# 


# 3.201. pager
# 
# Type: path
# Default: “builtin”
# 
# This variable specifies which pager you would like to use to view messages. The
# value “builtin” means to use the built-in pager, otherwise this variable should
# specify the pathname of the external pager you would like to use.
# 
# Using an external pager may have some disadvantages: Additional keystrokes are
# necessary because you can't call mutt functions directly from the pager, and
# screen resizes cause lines longer than the screen width to be badly formatted
# in the help menu.
# 
# When using an external pager, also see $prompt_after which defaults set.
# 


# 3.202. pager_context
# 
# Type: number
# Default: 0
# 
# This variable controls the number of lines of context that are given when
# displaying the next or previous page in the internal pager. By default, Mutt
# will display the line after the last one on the screen at the top of the next
# page (0 lines of context).
# 
# This variable also specifies the amount of context given for search results. If
# positive, this many lines will be given before a match, if 0, the match will be

# 3.204. pager_index_lines
# 
# Type: number
# Default: 0
# 
# Determines the number of lines of a mini-index which is shown when in the
# pager. The current message, unless near the top or bottom of the folder, will
# be roughly one third of the way down this mini-index, giving the reader the
# context of a few messages before and after the message. This is useful, for
# example, to determine how many messages remain to be read in the current
# thread. One of the lines is reserved for the status bar from the index, so a
# setting of 6 will only show 5 lines of the actual index. A value of 0 results
# in no index being shown. If the number of messages in the current folder is
# less than $pager_index_lines, then the index will only use as many lines as it
# needs. 
# 
set pager_index_lines=$menu_context


# 3.205. pager_stop
# 
# Type: boolean

# 3.207. pgp_auto_decode
# 
# Type: boolean
# Default: no
# 
# If set, mutt will automatically attempt to decrypt traditional PGP messages
# whenever the user performs an operation which ordinarily would result in the
# contents of the message being operated on. For example, if the user displays a
# pgp-traditional message which has not been manually checked with the
# <check-traditional-pgp> function, mutt will automatically check the message for
# traditional pgp.
# 
set pgp_auto_decode=yes


# 3.208. pgp_autoinline
# 
# Type: boolean
# Default: no
# 
# This option controls whether Mutt generates old-style inline (traditional) PGP
# encrypted or signed messages under certain circumstances. This can be
# overridden by use of the pgp menu, when inline is not required. The GPGME
# backend does not support this option.
# 
# Note that Mutt might automatically use PGP/MIME for messages which consist of
# more than a single MIME part. Mutt can be configured to ask before sending PGP/
# MIME messages when inline (traditional) would not work.
# 
# Also see the $pgp_mime_auto variable.
# 
# Also note that using the old-style PGP message format is strongly deprecated.
# (PGP only)
# 


# 3.209. pgp_check_exit
# 
# Type: boolean
# Default: yes
# 
# If set, mutt will check the exit code of the PGP subprocess when signing or
# encrypting. A non-zero exit code means that the subprocess failed. (PGP only)
# 


# 3.210. pgp_check_gpg_decrypt_status_fd
# 
# Type: boolean
# Default: yes
# 
# If set, mutt will check the status file descriptor output of
# $pgp_decrypt_command and $pgp_decode_command for GnuPG status codes indicating
# successful decryption. This will check for the presence of DECRYPTION_OKAY,
# absence of DECRYPTION_FAILED, and that all PLAINTEXT occurs between the
# BEGIN_DECRYPTION and END_DECRYPTION status codes.
# 
# If unset, mutt will instead match the status fd output against
# $pgp_decryption_okay. (PGP only)
# 


# 3.211. pgp_clearsign_command
# 
# Type: string
# Default: (empty)
# 
# This format is used to create an old-style “clearsigned” PGP message. Note that
# the use of this format is strongly deprecated.
# 
# This is a format string, see the $pgp_decode_command command for possible
# printf(3)-like sequences. (PGP only)
# 


# 3.212. pgp_decode_command
# 
# Type: string
# Default: (empty)

# 


# 3.214. pgp_decryption_okay
# 
# Type: regular expression
# Default: (empty)
# 
# If you assign text to this variable, then an encrypted PGP message is only
# considered successfully decrypted if the output from $pgp_decrypt_command
# contains the text. This is used to protect against a spoofed encrypted message,
# with multipart/encrypted headers but containing a block that is not actually
# encrypted. (e.g. simply signed and ascii armored text).
# 
# Note that if $pgp_check_gpg_decrypt_status_fd is set, this variable is ignored.
# (PGP only)
# 


# 3.215. pgp_default_key
# 
# Type: string
# Default: (empty)
# 
# This is the default key-pair to use for PGP operations. It will be used for
# encryption (see $postpone_encrypt and $pgp_self_encrypt).
# 
# It will also be used for signing unless $pgp_sign_as is set.
# 
# The (now deprecated) pgp_self_encrypt_as is an alias for this variable, and
# should no longer be used. (PGP only)
# 


# 3.216. pgp_encrypt_only_command
# 
# Type: string
# Default: (empty)
# 
# This command is used to encrypt a body part without signing it.

# printf(3)-like sequences. (PGP only)
# 


# 3.220. pgp_getkeys_command
# 
# Type: string
# Default: (empty)
# 
# This command is invoked whenever Mutt needs to fetch the public key associated
# with an email address. Of the sequences supported by $pgp_decode_command, %r is
# the only printf(3)-like sequence used with this format. Note that in this case,
# %r expands to the email address, not the public key ID (the key ID is unknown,
# which is why Mutt is invoking this command). (PGP only)
# 


# 3.221. pgp_good_sign
# 
# Type: regular expression
# Default: (empty)
# 
# If you assign a text to this variable, then a PGP signature is only considered
# verified if the output from $pgp_verify_command contains the text. Use this
# variable if the exit code from the command is 0 even for bad signatures. (PGP
# only) 
# 


# 3.222. pgp_ignore_subkeys
# 
# Type: boolean
# Default: yes
# 
# Setting this variable will cause Mutt to ignore OpenPGP subkeys. Instead, the
# principal key will inherit the subkeys' capabilities. Unset this if you want to
# play interesting key selection games. (PGP only)
# 


# 3.223. pgp_import_command
# 
# Type: string
# Default: (empty)
# 
# This command is used to import a key from a message into the user's public key
# ring. 
# 
# This is a format string, see the $pgp_decode_command command for possible
# printf(3)-like sequences. (PGP only)
# 


# 3.224. pgp_list_pubring_command

# Default: (empty)
# 
# This command is used to list the public key ring's contents. The output format
# must be analogous to the one used by
# 
# gpg --list-keys --with-colons --with-fingerprint
# 
# This format is also generated by the mutt_pgpring utility which comes with
# mutt. 
# 
# Note: gpg's fixed-list-mode option should not be used. It produces a different
# date format which may result in mutt showing incorrect key generation dates.
# 
# This is a format string, see the $pgp_decode_command command for possible
# printf(3)-like sequences. Note that in this case, %r expands to the search
# string, which is a list of one or more quoted values such as email address,
# name, or keyid. (PGP only)
# 


# 3.225. pgp_list_secring_command
# 
# Type: string
# Default: (empty)

# 


# 3.226. pgp_long_ids
# 
# Type: boolean
# Default: yes
# 
# If set, use 64 bit PGP key IDs, if unset use the normal 32 bit key IDs. NOTE:
# Internally, Mutt has transitioned to using fingerprints (or long key IDs as a
# fallback). This option now only controls the display of key IDs in the key
# selection menu and a few other places. (PGP only)
# 


# 3.227. pgp_mime_auto
# 
# Type: quadoption
# Default: ask-yes
# 
# This option controls whether Mutt will prompt you for automatically sending a
# (signed/encrypted) message using PGP/MIME when inline (traditional) fails (for
# any reason).
# 
# Also note that using the old-style PGP message format is strongly deprecated.
# (PGP only)
# 


# 3.228. pgp_replyinline
# 
# Type: boolean
# Default: no
# 
# Setting this variable will cause Mutt to always attempt to create an inline
# (traditional) message when replying to a message which is PGP encrypted/signed
# inline. This can be overridden by use of the pgp menu, when inline is not
# required. This option does not automatically detect if the (replied-to) message
# is inline; instead it relies on Mutt internals for previously checked/flagged
# messages. 
# 
# Note that Mutt might automatically use PGP/MIME for messages which consist of
# more than a single MIME part. Mutt can be configured to ask before sending PGP/

# 3.229. pgp_retainable_sigs
# 
# Type: boolean
# Default: no
# 
# If set, signed and encrypted messages will consist of nested multipart/signed
# and multipart/encrypted body parts.
# 
# This is useful for applications like encrypted and signed mailing lists, where
# the outer layer (multipart/encrypted) can be easily removed, while the inner
# multipart/signed part is retained. (PGP only)
# 
set pgp_retainable_sigs=yes


# 3.230. pgp_self_encrypt

# $pgp_default_key. (PGP only)
# 


# 3.231. pgp_show_unusable
# 
# Type: boolean

# If you prefer reverse order of the above values, prefix it with “reverse-”.
# (PGP only)
# 


# 3.235. pgp_strict_enc
# 
# Type: boolean
# Default: yes

# with non-verifyable PGP signatures, so only change this if you know what you
# are doing. (PGP only)
# 


# 3.236. pgp_timeout
# 
# Type: number (long)

# 3.237. pgp_use_gpg_agent
# 
# Type: boolean
# Default: yes

# If set, mutt expects a gpg-agent(1) process will handle private key passphrase
# prompts. If unset, mutt will prompt for the passphrase and pass it via stdin to
# the pgp command.
# 
# Note that as of version 2.1, GnuPG automatically spawns an agent and requires
# the agent be used for passphrase management. Since that version is increasingly
# prevalent, this variable now defaults set.
# 
# Mutt works with a GUI or curses pinentry program. A TTY pinentry should not be
# used. 
# 
# If you are using an older version of GnuPG without an agent running, or another
# encryption program without an agent, you will need to unset this variable. (PGP
# only)

# 


# 3.240. pipe_decode
# 
# Type: boolean
# Default: no
# 
# Used in connection with the <pipe-message> function. When unset, Mutt will pipe
# the messages without any preprocessing. When set, Mutt will attempt to decode
# the messages first.
# 
# Also see $pipe_decode_weed, which controls whether headers will be weeded when
# this is set.
# 


# 3.241. pipe_decode_weed
# 
# Type: boolean
# Default: yes
# 
# For <pipe-message>, when $pipe_decode is set, this further controls whether
# Mutt will weed headers.
# 


# 3.242. pipe_sep
# 
# Type: string
# Default: “n”
# 
# The separator to add between messages when piping a list of tagged messages to
# an external Unix command.
# 


# 3.243. pipe_split
# 
# Type: boolean
# Default: no
# 
# Used in connection with the <pipe-message> function following <tag-prefix>. If
# this variable is unset, when piping a list of tagged messages Mutt will
# concatenate the messages and will pipe them all concatenated. When set, Mutt
# will pipe the messages one by one. In both cases the messages are piped in the
# current sorted order, and the $pipe_sep separator is added after each message.
# 


# 3.244. pop_auth_try_all
# 
# Type: boolean
# Default: yes
# 
# If set, Mutt will try all available authentication methods. When unset, Mutt
# will only fall back to other authentication methods if the previous methods are
# unavailable. If a method is available but authentication fails, Mutt will not
# connect to the POP server.
# 


# 3.245. pop_authenticators
# 
# Type: string
# Default: (empty)
# 
# This is a colon-delimited list of authentication methods mutt may attempt to
# use to log in to an POP server, in the order mutt should try them.
# Authentication methods are either “user”, “apop” or any SASL mechanism, e.g. “
# digest-md5”, “gssapi” or “cram-md5”. This option is case-insensitive. If this
# option is unset (the default) mutt will try all available methods, in order
# from most-secure to least-secure.
# 
# Example: 
# 
# set pop_authenticators="digest-md5:apop:user"
# 


# 3.246. pop_checkinterval
# 
# Type: number
# Default: 60
# 
# This variable configures how often (in seconds) mutt should look for new mail
# in the currently selected mailbox if it is a POP mailbox.

# 3.247. pop_delete
# 
# Type: quadoption
# Default: ask-no
# 
# If set, Mutt will delete successfully downloaded messages from the POP server
# when using the <fetch-mail> function. When unset, Mutt will download messages
# but also leave them on the POP server.
# 


# 3.248. pop_host
# 
# Type: string
# Default: (empty)
# 
# The name of your POP server for the <fetch-mail> function. You can also specify
# an alternative port, username and password, i.e.:
# 
# [pop[s]://][username[:password]@]popserver[:port] 
# 
# where “[...]” denotes an optional part.
# 


# 3.249. pop_last
# 
# Type: boolean
# Default: no
# 
# If this variable is set, mutt will try to use the “LAST” POP command for
# retrieving only unread messages from the POP server when using the <fetch-mail>
# function. 
# 


# 3.250. pop_oauth_refresh_command
# 
# Type: string
# Default: (empty)
# 
# The command to run to generate an OAUTH refresh token for authorizing your
# connection to your POP server. This command will be run on every connection
# attempt that uses the OAUTHBEARER authentication mechanism. See “oauth” for
# details. 
# 


# 3.251. pop_pass
# 
# Type: string
# Default: (empty)
# 
# Specifies the password for your POP account. If unset, Mutt will prompt you for
# your password when you open a POP mailbox.
# 
# Warning: you should only use this option when you are on a fairly secure
# machine, because the superuser can read your muttrc even if you are the only
# one who can read the file.
# 


# 3.252. pop_reconnect
# 
# Type: quadoption
# Default: ask-yes
# 
# Controls whether or not Mutt will try to reconnect to the POP server if the

# printf(3)-like sequences see the section on $index_format.
# 


# 3.255. postpone
# 
# Type: quadoption
# Default: ask-yes
# 
# Controls whether or not messages are saved in the $postponed mailbox when you
# elect not to send immediately.
# 
# Also see the $recall variable.
# 


# 3.256. postponed
# 
# Type: path
# Default: “~/postponed”
# 
# Mutt allows you to indefinitely “postpone sending a message” which you are
# editing. When you choose to postpone a message, Mutt saves it in the mailbox
# specified by this variable.
# 
# Also see the $postpone variable.
# 
set postponed="=drafts"


# 3.257. postpone_encrypt
# 
# Type: boolean
# Default: no
# 
# When set, postponed messages that are marked for encryption will be
# self-encrypted. Mutt will first try to encrypt using the value specified in
# $pgp_default_key or $smime_default_key. If those are not set, it will try the
# deprecated $postpone_encrypt_as. (Crypto only)
# 


# 3.258. postpone_encrypt_as
# 
# Type: string
# Default: (empty)
# 
# This is a deprecated fall-back variable for $postpone_encrypt. Please use

# If set, a shell command to be executed if mutt fails to establish a connection
# to the server. This is useful for setting up secure connections, e.g. with ssh
# (1). If the command returns a nonzero status, mutt gives up opening the server.
# Example: 
# 
# set preconnect="ssh -f -q -L 1234:mailhost.net:143 mailhost.net sleep 20 < /dev/null > /dev/null"
# 
# Mailbox “foo” on “mailhost.net” can now be reached as “{localhost:1234}foo”.
# 
# Note: For this example to work, you must be able to log in to the remote
# machine without having to enter a password.
# 


# 3.260. print
# 
# Type: quadoption
# Default: ask-no
# 
# Controls whether or not Mutt really prints messages. This is set to “ask-no” by
# default, because some people accidentally hit “p” often.
# 


# 3.261. print_command
# 
# Type: path
# Default: “lpr”
# 
# This specifies the command pipe that should be used to print messages.
# 
set print_command="muttprint"


# 3.262. print_decode
# 
# Type: boolean
# Default: yes
# 
# Used in connection with the <print-message> function. If this option is set,
# the message is decoded before it is passed to the external command specified by
# $print_command. If this option is unset, no processing will be applied to the
# message when printing it. The latter setting may be useful if you are using
# some advanced printer filter which is able to properly format e-mail messages
# for printing.
# 
# Also see $print_decode_weed, which controls whether headers will be weeded when
# this is set.
# 


# 3.263. print_decode_weed
# 
# Type: boolean
# Default: yes
# 
# For <print-message>, when $print_decode is set, this further controls whether
# Mutt will weed headers.
# 


# 3.264. print_split
# 
# Type: boolean
# Default: no
# 
# Used in connection with the <print-message> function. If this option is set,
# the command specified by $print_command is executed once for each message which
# is to be printed. If this option is unset, the command specified by
# $print_command is executed only once, and all the messages are concatenated,
# with a form feed as the message separator.
# 
# Those who use the enscript(1) program's mail-printing mode will most likely
# want to set this option.
# 
set print_split=yes


# 3.265. prompt_after
# 
# Type: boolean
# Default: yes
# 
# If you use an external $pager, setting this variable will cause Mutt to prompt
# you for a command when the pager exits rather than returning to the index menu.
# If unset, Mutt will return to the index menu when the external pager exits.
# 


# 3.266. query_command
# 
# Type: path
# Default: (empty)
# 
# This specifies the command Mutt will use to make external address queries. The
# string may contain a “%s”, which will be substituted with the query string the
# user types. Mutt will add quotes around the string substituted for “%s”
# automatically according to shell quoting rules, so you should avoid adding your
# own. If no “%s” is found in the string, Mutt will append the user's query to
# the end of the string. See “query” for more information.
# 
set query_command="lbdbq"


# 3.267. query_format
# 
# Type: string
# Default: “%4c %t %-25.25a %-25.25n %?e?(%e)?”
# 
# This variable describes the format of the “query” menu. The following printf(3)
# -style sequences are understood:
# 
# ┌───┬─────────────────────────────────────────────────────┐ 
# │%a │destination address                                  │

# ├───┼─────────────────────────────────────────────────────┤ 
# │%|X│pad to the end of the line with “X”                  │
# ├───┼─────────────────────────────────────────────────────┤ 
# │%*X│soft-fill with character “X” as pad                  │
# └───┴─────────────────────────────────────────────────────┘ 
# 
# For an explanation of “soft-fill”, see the $index_format documentation.
# 
# * = can be optionally printed if nonzero, see the $status_format documentation.
# 


# 3.268. quit
# 
# Type: quadoption
# Default: yes
# 
# This variable controls whether “quit” and “exit” actually quit from mutt. If
# this option is set, they do quit, if it is unset, they have no effect, and if
# it is set to ask-yes or ask-no, you are prompted for confirmation when you try
# to quit.
# 


# 3.269. quote_regexp
# 
# Type: regular expression
# Default: “^([ t]*[|>:}#])+”
# 
# A regular expression used in the internal pager to determine quoted sections of
# text in the body of a message. Quoted text may be filtered out using the
# <toggle-quoted> command, or colored according to the “color quoted” family of
# directives. 
# 
# Higher levels of quoting may be colored differently (“color quoted1”, “color
# quoted2”, etc.). The quoting level is determined by removing the last character
# from the matched text and recursively reapplying the regular expression until
# it fails to produce a match.
# 
# Match detection may be overridden by the $smileys regular expression.
# 


# 3.270. read_inc
# 
# Type: number
# Default: 10
# 
# If set to a value greater than 0, Mutt will display which message it is
# currently on when reading a mailbox or when performing search actions such as
# search and limit. The message is printed after this many messages have been
# read or searched (e.g., if set to 25, Mutt will print a message when it is at
# message 25, and then again when it gets to message 50). This variable is meant
# to indicate progress when reading or searching large mailboxes which may take
# some time. When set to 0, only a single message will appear before the reading
# the mailbox.
# 
# Also see the $write_inc, $net_inc and $time_inc variables and the “tuning”
# section of the manual for performance considerations.
# 


# 3.271. read_only
# 
# Type: boolean
# Default: no
# 
# If set, all folders are opened in read-only mode.
# 


# 3.272. realname
# 
# Type: string
# Default: (empty)
# 
# This variable specifies what “real” or “personal” name should be used when
# sending messages.
# 
# By default, this is the GECOS field from /etc/passwd. Note that this variable
# will not be used when the user has set a real name in the $from variable.
# 


# 3.273. recall
# 
# Type: quadoption
# Default: ask-yes
# 
# Controls whether or not Mutt recalls postponed messages when composing a new
# message. 
# 
# Setting this variable to yes is not generally useful, and thus not recommended.
# Note that the <recall-message> function can be used to manually recall
# postponed messages.
# 
# Also see $postponed variable.
# 
set recall=no


# 3.274. record
# 
# Type: path
# Default: “~/sent”
# 
# This specifies the file into which your outgoing messages should be appended.
# (This is meant as the primary method for saving a copy of your messages, but
# another way to do this is using the “my_hdr” command to create a “Bcc:” field
# with your email address in it.)
# 
# The value of $record is overridden by the $force_name and $save_name variables,
# and the “fcc-hook” command. Also see $copy and $write_bcc.
# 
# Multiple mailboxes may be specified if $fcc_delimiter is set to a string
# delimiter. 
# 
set record="=store"


# 3.275. reflow_space_quotes
# 
# Type: boolean
# Default: yes
# 
# This option controls how quotes from format=flowed messages are displayed in
# the pager and when replying (with $text_flowed unset). When set, this option
# adds spaces after each level of quote marks, turning ">>>foo" into "> > > foo".
# 
# Note: If $reflow_text is unset, this option has no effect. Also, this option
# does not affect replies when $text_flowed is set.
# 


# 3.276. reflow_text
# 
# Type: boolean
# Default: yes
# 
# When set, Mutt will reformat paragraphs in text/plain parts marked format=
# flowed. If unset, Mutt will display paragraphs unaltered from how they appear
# in the message body. See RFC3676 for details on the format=flowed format.
# 
# Also see $reflow_wrap, and $wrap.
# 


# 3.277. reflow_wrap
# 
# Type: number
# Default: 78
# 
# This variable controls the maximum paragraph width when reformatting text/plain
# parts when $reflow_text is set. When the value is 0, paragraphs will be wrapped
# at the terminal's right margin. A positive value sets the paragraph width
# relative to the left margin. A negative value set the paragraph width relative
# to the right margin.
# 
# Also see $wrap.
# 
set reflow_wrap=-10


# 3.278. reply_regexp
# 
# Type: regular expression
# Default: “^(re([[0-9]+])*|aw):[ t]*”
# 
# A regular expression used to recognize reply messages when threading and
# replying. The default value corresponds to the English "Re:" and the German
# "Aw:". 
# 
set reply_regexp="^((re([-[(]?[[:digit:]]+[)]]?)?|a(nt)?w(ort)?|wg|s(gkb|v)):[[:space:]]*)+"


# 3.279. reply_self
# 
# Type: boolean
# Default: no
# 
# If unset and you are replying to a message sent by you, Mutt will assume that
# you want to reply to the recipients of that message rather than to yourself.
# 
# Also see the “alternates” command.
# 


# 3.280. reply_to
# 
# Type: quadoption
# Default: ask-yes
# 
# If set, when replying to a message, Mutt will use the address listed in the
# Reply-to: header as the recipient of the reply. If unset, it will use the
# address in the From: header field instead. This option is useful for reading a
# mailing list that sets the Reply-To: header field to the list address and you
# want to send a private message to the author of a message.
# 


# 3.281. resolve
# 
# Type: boolean
# Default: yes
# 
# When set, the cursor will be automatically advanced to the next (possibly
# undeleted) message whenever a command that modifies the current message is
# executed. 
# 


# 3.282. resume_draft_files
# 
# Type: boolean
# Default: no
# 
# If set, draft files (specified by -H on the command line) are processed
# similarly to when resuming a postponed message. Recipients are not prompted
# for; send-hooks are not evaluated; no alias expansion takes place; user-defined
# headers and signatures are not added to the message.
# 


# 3.283. resume_edited_draft_files
# 
# Type: boolean
# Default: yes
# 
# If set, draft files previously edited (via -E -H on the command line) will have
# $resume_draft_files automatically set when they are used as a draft file again.
# 
# The first time a draft file is saved, mutt will add a header,
# X-Mutt-Resume-Draft to the saved file. The next time the draft file is read in,
# if mutt sees the header, it will set $resume_draft_files.
# 
# This option is designed to prevent multiple signatures, user-defined headers,
# and other processing effects from being made multiple times to the draft file.
# 


# 3.284. reverse_alias
# 
# Type: boolean
# Default: no
# 
# This variable controls whether or not Mutt will display the “personal” name
# from your aliases in the index menu if it finds an alias that matches the
# message's sender. For example, if you have the following alias:
# 
# alias juser abd30425@somewhere.net (Joe User)
# 
# and then you receive mail which contains the following header:
# 
# From: abd30425@somewhere.net
# 
# It would be displayed in the index menu as “Joe User” instead of “
# abd30425@somewhere.net.” This is useful when the person's e-mail address is not
# human friendly.
# 


# 3.285. reverse_name
# 
# Type: boolean
# Default: no
# 
# It may sometimes arrive that you receive mail to a certain machine, move the
# messages to another machine, and reply to some the messages from there. If this
# variable is set, the default From: line of the reply messages is built using
# the address where you received the messages you are replying to if that address
# matches your “alternates”. If the variable is unset, or the address that would
# be used doesn't match your “alternates”, the From: line will use your address
# on the current machine.
# 
# Also see the “alternates” command and $reverse_realname.
# 
set reverse_name=yes


# 3.286. reverse_realname
# 
# Type: boolean
# Default: yes
# 
# This variable fine-tunes the behavior of the $reverse_name feature.
# 
# When it is unset, Mutt will remove the real name part of a matching address.
# This allows the use of the email address without having to also use what the
# sender put in the real name field.
# 
# When it is set, Mutt will use the matching address as-is.
# 
# In either case, a missing real name will be filled in afterwards using the
# value of $realname.
# 


# 3.287. rfc2047_parameters
# 
# Type: boolean
# Default: no
# 
# When this variable is set, Mutt will decode RFC2047-encoded MIME parameters.
# You want to set this variable when mutt suggests you to save attachments to
# files named like:
# 
# =?iso-8859-1?Q?file=5F=E4=5F991116=2Ezip?= 
# 
# When this variable is set interactively, the change won't be active until you
# change folders.
# 
# Note that this use of RFC2047's encoding is explicitly prohibited by the
# standard, but nevertheless encountered in the wild.
# 
# Also note that setting this parameter will not have the effect that mutt
# generates this kind of encoding. Instead, mutt will unconditionally use the
# encoding specified in RFC2231.
# 
set rfc2047_parameters=yes


# 3.288. save_address
# 
# Type: boolean
# Default: no
# 
# If set, mutt will take the sender's full address when choosing a default folder
# for saving a mail. If $save_name or $force_name is set too, the selection of
# the Fcc folder will be changed as well.
# 


# 3.289. save_empty
# 
# Type: boolean
# Default: yes
# 
# When unset, mailboxes which contain no saved messages will be removed when
# closed (the exception is $spoolfile which is never removed). If set, mailboxes
# are never removed.
# 
# Note: This only applies to mbox and MMDF folders, Mutt does not delete MH and
# Maildir directories.
# 


# 3.290. save_history
# 
# Type: number
# Default: 0
# 
# This variable controls the size of the history (per category) saved in the
# $history_file file.
# 
set save_history=100


# 3.291. save_name
# 
# Type: boolean
# Default: no
# 
# This variable controls how copies of outgoing messages are saved. When set, a
# check is made to see if a mailbox specified by the recipient address exists
# (this is done by searching for a mailbox in the $folder directory with the
# username part of the recipient address). If the mailbox exists, the outgoing
# message will be saved to that mailbox, otherwise the message is saved to the
# $record mailbox.
# 
# Also see the $force_name variable.
# 


# 3.292. score
# 
# Type: boolean
# Default: yes
# 
# When this variable is unset, scoring is turned off. This can be useful to
# selectively disable scoring for certain folders when the
# $score_threshold_delete variable and related are used.
# 


# 3.293. score_threshold_delete
# 
# Type: number
# Default: -1
# 
# Messages which have been assigned a score equal to or lower than the value of
# this variable are automatically marked for deletion by mutt. Since mutt scores
# are always greater than or equal to zero, the default setting of this variable
# will never mark a message for deletion.
# 


# 3.294. score_threshold_flag
# 
# Type: number
# Default: 9999
# 
# Messages which have been assigned a score greater than or equal to this
# variable's value are automatically marked "flagged".
# 


# 3.295. score_threshold_read
# 
# Type: number
# Default: -1
# 
# Messages which have been assigned a score equal to or lower than the value of
# this variable are automatically marked as read by mutt. Since mutt scores are
# always greater than or equal to zero, the default setting of this variable will
# never mark a message read.
# 


# 3.296. search_context
# 
# Type: number
# Default: 0
# 
# For the pager, this variable specifies the number of lines shown before search
# results. By default, search results will be top-aligned.
# 
set search_context=5


# 3.297. send_charset
# 
# Type: string
# Default: “us-ascii:iso-8859-1:utf-8”
# 
# A colon-delimited list of character sets for outgoing messages. Mutt will use
# the first character set into which the text can be converted exactly. If your
# $charset is not “iso-8859-1” and recipients may not understand “UTF-8”, it is
# advisable to include in the list an appropriate widely used standard character
# set (such as “iso-8859-2”, “koi8-r” or “iso-2022-jp”) either instead of or
# after “iso-8859-1”.
# 
# In case the text cannot be converted into one of these exactly, mutt uses
# $charset as a fallback.
# 
set send_charset="utf-8"


# 3.298. send_multipart_alternative
# 
# Type: quadoption
# Default: no
# 
# If set, Mutt will generate a multipart/alternative container and an alternative
# part using the filter script specified in $send_multipart_alternative_filter.
# See the section “MIME Multipart/Alternative” (alternative-order).
# 
# Note that enabling multipart/alternative is not compatible with inline PGP
# encryption. Mutt will prompt to use PGP/MIME in that case.
# 
set send_multipart_alternative=yes


# 3.299. send_multipart_alternative_filter
# 
# Type: path
# Default: (empty)
# 
# This specifies a filter script, which will convert the main (composed) message
# of the email to an alternative format. The message will be piped to the
# filter's stdin. The expected output of the filter is the generated mime type,
# e.g. text/html, followed by a blank line, and then the converted content. See
# the section “MIME Multipart/Alternative” (alternative-order).
# 
set send_multipart_alternative_filter=$my_confdir/markdown2html


# 3.300. sendmail
# 
# Type: path
# Default: “/usr/sbin/sendmail -oem -oi”
# 
# Specifies the program and arguments used to deliver mail sent by Mutt. Mutt
# expects that the specified program interprets additional arguments as recipient
# addresses. Mutt appends all recipients after adding a -- delimiter (if not
# already present). Additional flags, such as for $use_8bitmime,
# $use_envelope_from, $dsn_notify, or $dsn_return will be added before the
# delimiter. 
# 
# See also: $write_bcc.
# 
set sendmail="$my_confdir/sendmail"


# 3.301. sendmail_wait
# 
# Type: number
# Default: 0
# 
# Specifies the number of seconds to wait for the $sendmail process to finish
# before giving up and putting delivery in the background.
# 
# Mutt interprets the value of this variable as follows:
# 
# ┌──┬──────────────────────────────────────────────────────────────────┐ 
# │>0│number of seconds to wait for sendmail to finish before continuing│
# ├──┼──────────────────────────────────────────────────────────────────┤ 
# │0 │wait forever for sendmail to finish                               │
# ├──┼──────────────────────────────────────────────────────────────────┤ 
# │<0│always put sendmail in the background without waiting             │
# └──┴──────────────────────────────────────────────────────────────────┘ 
# 
# Note that if you specify a value other than 0, the output of the child process
# will be put in a temporary file. If there is some error, you will be informed
# as to where to find the output.
# 


# 3.302. shell
# 
# Type: path
# Default: (empty)
# 
# Command to use when spawning a subshell. By default, the user's login shell
# from /etc/passwd is used.
# 


# 3.303. sidebar_delim_chars
# 
# Type: string
# Default: “/.”
# 
# This contains the list of characters which you would like to treat as folder
# separators for displaying paths in the sidebar.
# 
# Local mail is often arranged in directories: `dir1/dir2/mailbox'.
# 
# set sidebar_delim_chars='/'
# 
# IMAP mailboxes are often named: `folder1.folder2.mailbox'.
# 
# set sidebar_delim_chars='.'
# 
# See also: $sidebar_short_path, $sidebar_folder_indent, $sidebar_indent_string.
# 


# 3.304. sidebar_divider_char
# 
# Type: string
# Default: “|”
# 
# This specifies the characters to be drawn between the sidebar (when visible)
# and the other Mutt panels. ASCII and Unicode line-drawing characters are
# supported. 
# 
set sidebar_divider_char=" "


# 3.305. sidebar_folder_indent
# 
# Type: boolean
# Default: no
# 
# Set this to indent mailboxes in the sidebar.
# 
# See also: $sidebar_short_path, $sidebar_indent_string, $sidebar_delim_chars.
# 
set sidebar_folder_indent=yes


# 3.306. sidebar_format
# 
# Type: string
# Default: “%B%*  %n”
# 
# This variable allows you to customize the sidebar display. This string is
# similar to $index_format, but has its own set of printf(3)-like sequences:
# 
# ┌───┬─────────────────────────────────────────────────────────────────────────┐

# mail. 
# 
# See also: sidebar_whitelist.
# 


# 3.309. sidebar_next_new_wrap
# 
# Type: boolean
# Default: no
# 
# When set, the <sidebar-next-new> command will not stop and the end of the list
# of mailboxes, but wrap around to the beginning. The <sidebar-prev-new> command
# is similarly affected, wrapping around to the end of the list.
# 
set sidebar_next_new_wrap=yes


# 3.310. sidebar_relative_shortpath_indent
# 
# Type: boolean
# Default: no
# 
# When set, this option changes how $sidebar_short_path and
# $sidebar_folder_indent perform shortening and indentation: both will look at
# the previous sidebar entries and shorten/indent relative to the most recent
# parent. 
# 
# An example of this option set/unset for mailboxes listed in this order, with
# $sidebar_short_path=yes, $sidebar_folder_indent=yes, and $sidebar_indent_string
# ="→": 
# 
# ┌─────────┬────┬─────┐ 
# │mailbox │set │unset│
# ├─────────┼────┼─────┤ 
# │=a.b │=a.b│→b   │
# ├─────────┼────┼─────┤ 
# │=a.b.c.d │→c.d│→→→d │
# ├─────────┼────┼─────┤ 
# │=a.b.e │→e  │→→e  │
# └─────────┴────┴─────┘ 
# 
# The second line illustrates most clearly. With this option set, =a.b.c.d is
# shortened relative to =a.b, becoming c.d; it is also indented one place
# relative to =a.b. With this option unset =a.b.c.d is always shortened to the
# last part of the mailbox, d and is indented three places, with respect to
# $folder (represented by '=').
# 
# When set, the third line will also be indented and shortened relative to the
# first line.
# 


# 3.311. sidebar_short_path
# 
# Type: boolean
# Default: no
# 
# By default the sidebar will show the mailbox's path, relative to the $folder
# variable. Setting sidebar_shortpath=yes will shorten the names relative to the
# previous name. Here's an example:
# 
# ┌────────────┬─────────────┬───────────────────────────────────────────────┐ 
# │shortpath=no│shortpath=yes│shortpath=yes, folderindent=yes, indentstr=".."│
# ├────────────┼─────────────┼───────────────────────────────────────────────┤

# 
set sidebar_short_path=yes


# 3.312. sidebar_sort_method
# 
# Type: sort order
# Default: unsorted
# 
# Specifies how to sort mailbox entries in the sidebar. By default, the entries
# are sorted alphabetically. Valid values:
# 
# • alpha (alphabetically)
# 
# • count (all message count)
# 
# • flagged (flagged message count)
# 
# • name (alphabetically)
# 
# • new (unread message count)
# 
# • path (alphabetically)
# 
# • unread (unread message count)
# 
# • unsorted
# 
# You may optionally use the “reverse-” prefix to specify reverse sorting order
# (example: “set sidebar_sort_method=reverse-alpha”).
# 
set sidebar_sort_method=path


# 3.313. sidebar_use_mailbox_shortcuts
# 
# Type: boolean
# Default: no
# 
# When set, sidebar mailboxes will be displayed with mailbox shortcut prefixes "=
# " or "~".
# 
# When unset, the sidebar will trim off a matching $folder prefix but otherwise
# not use mailbox shortcuts.
# 


# 3.314. sidebar_visible
# 
# Type: boolean
# Default: no
# 
# This specifies whether or not to show sidebar. The sidebar shows a list of all
# your mailboxes.
# 
# See also: $sidebar_format, $sidebar_width
# 
set sidebar_visible=no


# 3.315. sidebar_width
# 
# Type: number
# Default: 30
# 
# This controls the width of the sidebar. It is measured in screen columns. For
# example: sidebar_width=20 could display 20 ASCII characters, or 10 Chinese
# characters. 
# 
set sidebar_width=20


# 3.316. sig_dashes
# 
# Type: boolean
# Default: yes
# 
# If set, a line containing “-- ” (note the trailing space) will be inserted
# before your $signature. It is strongly recommended that you not unset this
# variable unless your signature contains just your name. The reason for this is
# because many software packages use “-- n” to detect your signature. For
# example, Mutt has the ability to highlight the signature in a different color
# in the built-in pager.
# 
set sig_dashes=no


# 3.317. sig_on_top
# 
# Type: boolean
# Default: no
# 
# If set, the signature will be included before any quoted or forwarded text. It
# is strongly recommended that you do not set this variable unless you really
# know what you are doing, and are prepared to take some heat from netiquette
# guardians. 
# 


# 3.318. signature
# 
# Type: path
# Default: “~/.signature”
# 
# Specifies the filename of your signature, which is appended to all outgoing
# messages. If the filename ends with a pipe (“|”), it is assumed that filename
# is a shell command and input should be read from its standard output.
# 


# 3.319. simple_search
# 
# Type: string
# Default: “~f %s | ~s %s”
# 
# Specifies how Mutt should expand a simple search into a real search pattern. A
# simple search is one that does not contain any of the “~” pattern modifiers.
# See “patterns” for more information on search patterns.
# 
# For example, if you simply type “joe” at a search or limit prompt, Mutt will
# automatically expand it to the value specified by this variable by replacing “
# %s” with the supplied string. For the default value, “joe” would be expanded
# to: “~f joe | ~s joe”.
# 
set simple_search="~L %s | ~s %s"


# 3.320. size_show_bytes
# 
# Type: boolean
# Default: no
# 
# If set, message sizes will display bytes for values less than 1 kilobyte. See
# formatstrings-size. 
# 


# 3.321. size_show_fractions
# 
# Type: boolean
# Default: yes
# 
# If set, message sizes will be displayed with a single decimal value for sizes
# from 0 to 10 kilobytes and 1 to 10 megabytes. See formatstrings-size.
# 


# 3.322. size_show_mb
# 
# Type: boolean
# Default: yes
# 
# If set, message sizes will display megabytes for values greater than or equal
# to 1 megabyte. See formatstrings-size.
# 


# 3.323. size_units_on_left
# 
# Type: boolean
# Default: no
# 
# If set, message sizes units will be displayed to the left of the number. See
# formatstrings-size. 
# 


# 3.324. sleep_time
# 
# Type: number
# Default: 1
# 
# Specifies time, in seconds, to pause while displaying certain informational
# messages, while moving from folder to folder and after expunging messages from
# the current folder. The default is to pause one second, so a value of zero for
# this option suppresses the pause.
# 


# 3.325. smart_wrap
# 
# Type: boolean
# Default: yes
# 
# Controls the display of lines longer than the screen width in the internal
# pager. If set, long lines are wrapped at a word boundary. If unset, lines are
# simply wrapped at the screen edge. Also see the $markers variable.
# 


# 3.326. smileys
# 
# Type: regular expression
# Default: “(>From )|(:[-^]?[][)(><}{|/DP])”
# 
# The pager uses this variable to catch some common false positives of
# $quote_regexp, most notably smileys and not consider a line quoted text if it
# also matches $smileys. This mostly happens at the beginning of a line.
# 


# 3.327. smime_ask_cert_label
# 
# Type: boolean
# Default: yes
# 
# This flag controls whether you want to be asked to enter a label for a
# certificate about to be added to the database or not. It is set by default. (S/
# MIME only)
# 


# 3.328. smime_ca_location
# 
# Type: path
# Default: (empty)
# 
# This variable contains the name of either a directory, or a file which contains
# trusted certificates for use with OpenSSL. (S/MIME only)
# 


# 3.329. smime_certificates
# 
# Type: path
# Default: (empty)
# 
# Since for S/MIME there is no pubring/secring as with PGP, mutt has to handle
# storage and retrieval of keys by itself. This is very basic right now, and keys
# and certificates are stored in two different directories, both named as the
# hash-value retrieved from OpenSSL. There is an index file which contains
# mailbox-address keyid pairs, and which can be manually edited. This option
# points to the location of the certificates. (S/MIME only)
# 
set smime_certificates="~/.smime/certificates"


# 3.330. smime_decrypt_command
# 
# Type: string
# Default: (empty)
# 
# This format string specifies a command which is used to decrypt application/
# x-pkcs7-mime attachments.
# 
# The OpenSSL command formats have their own set of printf(3)-like sequences
# similar to PGP's:

# Type: boolean
# Default: yes
# 
# If set (default) this tells mutt to use the default key for decryption.
# Otherwise, if managing multiple certificate-key-pairs, mutt will try to use the
# mailbox-address to determine the key to use. It will ask you to supply a key,
# if it can't find one. (S/MIME only)
# 


# 3.332. smime_default_key
# 
# Type: string
# Default: (empty)
# 
# This is the default key-pair to use for S/MIME operations, and must be set to
# the keyid (the hash-value that OpenSSL generates) to work properly.
# 
# It will be used for encryption (see $postpone_encrypt and $smime_self_encrypt).
# If GPGME is enabled, this is the key id displayed by gpgsm.
# 
# It will be used for decryption unless $smime_decrypt_use_default_key is unset.
# 
# It will also be used for signing unless $smime_sign_as is set.

# 


# 3.336. smime_get_cert_email_command
# 
# Type: string
# Default: (empty)
# 
# This command is used to extract the mail address(es) used for storing X509
# certificates, and for verification purposes (to check whether the certificate
# was issued for the sender's mailbox).
# 
# This is a format string, see the $smime_decrypt_command command for possible
# printf(3)-like sequences. (S/MIME only)
# 


# 3.337. smime_get_signer_cert_command
# 
# Type: string

# 3.339. smime_is_default
# 
# Type: boolean
# Default: no
# 
# The default behavior of mutt is to use PGP on all auto-sign/encryption
# operations. To override and to use OpenSSL instead this must be set. However,
# this has no effect while replying, since mutt will automatically select the

# 


# 3.343. smime_sign_as
# 
# Type: string
# Default: (empty)
#

# 
# Type: string
# Default: (empty)
# 
# This is a colon-delimited list of authentication methods mutt may attempt to
# use to log in to an SMTP server, in the order mutt should try them.
# Authentication methods are any SASL mechanism, e.g. “digest-md5”, “gssapi” or “
# cram-md5”. This option is case-insensitive. If it is “unset” (the default) mutt
# will try all available methods, in order from most-secure to least-secure.
# 
# Example: 
# 
# set smtp_authenticators="digest-md5:cram-md5"
# 


# 3.351. smtp_oauth_refresh_command
# 
# Type: string
# Default: (empty)
# 
# The command to run to generate an OAUTH refresh token for authorizing your
# connection to your SMTP server. This command will be run on every connection
# attempt that uses the OAUTHBEARER authentication mechanism. See “oauth” for
# details. 
# 


# 3.352. smtp_pass
# 
# Type: string
# Default: (empty)
# 
# Specifies the password for your SMTP account. If unset, Mutt will prompt you
# for your password when you first send mail via SMTP. See $smtp_url to configure
# mutt to send mail via SMTP.
# 
# Warning: you should only use this option when you are on a fairly secure
# machine, because the superuser can read your muttrc even if you are the only
# one who can read the file.
# 


# 3.353. smtp_url
# 
# Type: string
# Default: (empty)
# 
# Defines the SMTP smarthost where sent messages should relayed for delivery.
# This should take the form of an SMTP URL, e.g.:
# 
# smtp[s]://[user[:pass]@]host[:port] 
# 
# where “[...]” denotes an optional part. Setting this variable overrides the
# value of the $sendmail variable.
# 
# Also see $write_bcc.
# 


# 3.354. sort
# 
# Type: sort order
# Default: date
# 
# Specifies how to sort messages in the “index” menu. Valid values are:
# 
# • date or date-sent
# 
# • date-received
# 
# • from
# 
# • mailbox-order (unsorted)
# 
# • score
# 
# • size
# 
# • spam
# 
# • subject
# 
# • threads
# 
# • to
# 
# You may optionally use the “reverse-” prefix to specify reverse sorting order
# (example: “set sort=reverse-date-sent”).
# 
set sort=threads


# 3.355. sort_alias
# 
# Type: sort order
# Default: alias
# 
# Specifies how the entries in the “alias” menu are sorted. The following are
# legal values:
# 
# • address (sort alphabetically by email address)
# 
# • alias (sort alphabetically by alias name)
# 
# • unsorted (leave in order specified in .muttrc)
# 


# 3.356. sort_aux
# 
# Type: sort order
# Default: date
# 
# This provides a secondary sort for messages in the “index” menu, used when the
# $sort value is equal for two messages.
# 
# When sorting by threads, this variable controls how threads are sorted in
# relation to other threads, and how the branches of the thread trees are sorted.
# This can be set to any value that $sort can, except “threads” (in that case,
# mutt will just use “date-sent”). You can also specify the “last-” prefix in
# addition to the “reverse-” prefix, but “last-” must come after “reverse-”. The
# “last-” prefix causes messages to be sorted against its siblings by which has
# the last descendant, using the rest of $sort_aux as an ordering. For instance,
# 
# set sort_aux=last-date-received
# 
# would mean that if a new message is received in a thread, that thread becomes
# the last one displayed (or the first, if you have “set sort=reverse-threads”.)
# 
# Note: For reversed-threads $sort order, $sort_aux is reversed again (which is
# not the right thing to do, but kept to not break any existing configuration
# setting). 
# 
set sort_aux=last-date-received


# 3.357. sort_browser
# 
# Type: sort order
# Default: alpha
# 
# Specifies how to sort entries in the file browser. By default, the entries are
# sorted alphabetically. Valid values:
# 
# • alpha (alphabetically)
# 
# • count
# 
# • date
# 
# • size
# 
# • unread
# 
# • unsorted
# 
# You may optionally use the “reverse-” prefix to specify reverse sorting order
# (example: “set sort_browser=reverse-date”).
# 


# 3.358. sort_browser_mailboxes
# 
# Type: sort order
# Default: unsorted
# 
# Specifies how to sort entries in the mailbox browser. By default, the entries
# are unsorted, displayed in the same order as listed in the “mailboxes” command.
# Valid values:
# 
# • alpha (alphabetically)
# 
# • count
# 
# • date
# 
# • size
# 
# • unread
# 
# • unsorted
# 
# You may optionally use the “reverse-” prefix to specify reverse sorting order
# (example: “set sort_browser_mailboxes=reverse-alpha”).
# 


# 3.359. sort_re
# 
# Type: boolean
# Default: yes
# 
# This variable is only useful when sorting by threads with $strict_threads unset
# . In that case, it changes the heuristic mutt uses to thread messages by
# subject. With $sort_re set, mutt will only attach a message as the child of
# another message by subject if the subject of the child message starts with a
# substring matching the setting of $reply_regexp. With $sort_re unset, mutt will
# attach the message whether or not this is the case, as long as the non-
# $reply_regexp parts of both messages are identical.
# 


# 3.360. spam_separator
# 
# Type: string
# Default: “,”
# 
# This variable controls what happens when multiple spam headers are matched: if
# unset, each successive header will overwrite any previous matches value for the
# spam label. If set, each successive match will append to the previous, using
# this variable's value as a separator.
# 


# 3.361. spoolfile
# 
# Type: path
# Default: (empty)
# 
# If your spool mailbox is in a non-default place where Mutt cannot find it, you
# can specify its location with this variable. Mutt will initially set this
# variable to the value of the environment variable $MAIL or $MAILDIR if either
# is defined.
# 
set spoolfile="=inbox"


# 3.362. ssl_ca_certificates_file
# 
# Type: path
# Default: (empty)
# 
# This variable specifies a file containing trusted CA certificates. Any server
# certificate that is signed with one of these CA certificates is also
# automatically accepted. (GnuTLS only)
# 
# Example: 
# 
# set ssl_ca_certificates_file=/etc/ssl/certs/ca-certificates.crt
# 
set ssl_ca_certificates_file="/etc/ssl/certs/ca-certificates.crt"


# 3.363. ssl_client_cert
# 
# Type: path
# Default: (empty)
# 
# The file containing a client certificate and its associated private key.
# 


# 3.364. ssl_force_tls
# 
# Type: boolean
# Default: yes
# 
# If this variable is set, Mutt will require that all connections to remote
# servers be encrypted. Furthermore it will attempt to negotiate TLS even if the
# server does not advertise the capability, since it would otherwise have to
# abort the connection anyway. This option supersedes $ssl_starttls.
# 


# 3.365. ssl_min_dh_prime_bits
# 
# Type: number
# Default: 0
# 
# This variable specifies the minimum acceptable prime size (in bits) for use in
# any Diffie-Hellman key exchange. A value of 0 will use the default from the
# GNUTLS library. (GnuTLS only)
# 


# 3.366. ssl_starttls
# 
# Type: quadoption
# Default: yes
# 
# If set (the default), mutt will attempt to use STARTTLS on servers advertising
# the capability. When unset, mutt will not attempt to use STARTTLS regardless of
# the server's capabilities.
# 
# Note that STARTTLS is subject to many kinds of attacks, including the ability
# of a machine-in-the-middle to suppress the advertising of support. Setting
# $ssl_force_tls is recommended if you rely on STARTTLS.
# 


# 3.367. ssl_use_sslv2
# 
# Type: boolean
# Default: no
# 
# If set , Mutt will use SSLv2 when communicating with servers that request it.
# N.B. As of 2011, SSLv2 is considered insecure, and using is inadvisable. See
# https://tools.ietf.org/html/rfc6176 . (OpenSSL only)
# 


# 3.368. ssl_use_sslv3
# 
# Type: boolean
# Default: no
# 
# If set , Mutt will use SSLv3 when communicating with servers that request it.
# N.B. As of 2015, SSLv3 is considered insecure, and using it is inadvisable. See
# https://tools.ietf.org/html/rfc7525 .
# 


# 3.369. ssl_use_tlsv1
# 
# Type: boolean
# Default: no
# 
# If set , Mutt will use TLSv1.0 when communicating with servers that request it.
# N.B. As of 2015, TLSv1.0 is considered insecure, and using it is inadvisable.
# See https://tools.ietf.org/html/rfc7525 .
# 


# 3.370. ssl_use_tlsv1_1
# 
# Type: boolean
# Default: no
# 
# If set , Mutt will use TLSv1.1 when communicating with servers that request it.
# N.B. As of 2015, TLSv1.1 is considered insecure, and using it is inadvisable.
# See https://tools.ietf.org/html/rfc7525 .
# 


# 3.371. ssl_use_tlsv1_2
# 
# Type: boolean
# Default: yes
# 
# If set , Mutt will use TLSv1.2 when communicating with servers that request it.
# 


# 3.372. ssl_use_tlsv1_3
# 
# Type: boolean
# Default: yes
# 
# If set , Mutt will use TLSv1.3 when communicating with servers that request it.
# 


# 3.373. ssl_usesystemcerts
# 
# Type: boolean
# Default: yes
# 
# If set to yes, mutt will use CA certificates in the system-wide certificate
# store when checking if a server certificate is signed by a trusted CA. (OpenSSL
# only) 
# 


# 3.374. ssl_verify_dates
# 
# Type: boolean
# Default: yes
# 
# If set (the default), mutt will not automatically accept a server certificate
# that is either not yet valid or already expired. You should only unset this for
# particular known hosts, using the <account-hook> function.
# 


# 3.375. ssl_verify_host
# 
# Type: boolean
# Default: yes
# 
# If set (the default), mutt will not automatically accept a server certificate
# whose host name does not match the host used in your folder URL. You should
# only unset this for particular known hosts, using the <account-hook> function.
# 


# 3.376. ssl_verify_host_override
# 
# Type: string
# Default: (empty)
# 
# Defines an alternate host name to verify the server certificate against. This
# should not be set unless you are sure what you are doing, but it might be
# useful for connection to a .onion host without a properly configured host name
# in the certificate. See $ssl_verify_host.
# 


# 3.377. ssl_verify_partial_chains
# 
# Type: boolean
# Default: no
# 
# This option should not be changed from the default unless you understand what
# you are doing.
# 
# Setting this variable to yes will permit verifying partial certification
# chains, i. e. a certificate chain where not the root, but an intermediate
# certificate CA, or the host certificate, are marked trusted (in
# $certificate_file), without marking the root signing CA as trusted.
# 
# (OpenSSL 1.0.2b and newer only).
# 


# 3.378. ssl_ciphers
# 
# Type: string
# Default: (empty)
# 
# Contains a colon-separated list of ciphers to use when using SSL. For OpenSSL,
# see ciphers(1) for the syntax of the string.
# 
# For GnuTLS, this option will be used in place of "NORMAL" at the start of the
# priority string. See gnutls_priority_init(3) for the syntax and more details.
# (Note: GnuTLS version 2.1.7 or higher is required.)
# 


# 3.379. status_chars
# 
# Type: string
# Default: “-*%A”
# 
# Controls the characters used by the “%r” indicator in $status_format. The first
# character is used when the mailbox is unchanged. The second is used when the
# mailbox has been changed, and it needs to be resynchronized. The third is used
# if the mailbox is in read-only mode, or if the mailbox will not be written when
# exiting that mailbox (You can toggle whether to write changes to a mailbox with
# the <toggle-write> operation, bound by default to “%”). The fourth is used to
# indicate that the current folder has been opened in attach- message mode
# (Certain operations like composing a new mail, replying, forwarding, etc. are
# not permitted in this mode).
# 


# 3.380. status_format
# 
# Type: string (localized)
# Default: “-%r-Mutt: %f [Msgs:%?M?%M/?%m%?n? New:%n?%?o? Old:%o?%?d? Del:%d?%?F?
# Flag:%F?%?t? Tag:%t?%?p? Post:%p?%?b? Inc:%b?%?B? Back:%B?%?l? %l?]---(%s/%S)
# -%>-(%P)---” 
# 
# Controls the format of the status line displayed in the “index” menu. This
# string is similar to $index_format, but has its own set of printf(3)-like
# sequences:

# 
# * = can be optionally printed if nonzero
# 
# Some of the above sequences can be used to optionally print a string if their
# value is nonzero. For example, you may only want to see the number of flagged
# messages if such messages exist, since zero is not particularly meaningful. To
# optionally print a string based upon one of the above sequences, the following
# construct is used:
# 
# %?<sequence_char>?<optional_string>? 
# 
# where sequence_char is a character from the table above, and optional_string is
# the string you would like printed if sequence_char is nonzero. optional_string
# may contain other sequences as well as normal text, but you may not nest
# optional strings.
# 
# Here is an example illustrating how to optionally print the number of new
# messages in a mailbox:
# 
# %?n?%n new messages.?
# 
# You can also switch between two strings using the following construct:
# 
# %?<sequence_char>?<if_string>&<else_string>? 
# 
# If the value of sequence_char is non-zero, if_string will be expanded,
# otherwise else_string will be expanded.
# 
# You can force the result of any printf(3)-like sequence to be lowercase by
# prefixing the sequence character with an underscore (“_”) sign. For example, if
# you want to display the local hostname in lowercase, you would use: “%_h”.
# 
# If you prefix the sequence character with a colon (“:”) character, mutt will
# replace any dots in the expansion by underscores. This might be helpful with
# IMAP folders that don't like dots in folder names.
# 
set status_format=" %r %f [m:%?M?%M/?%m%?n? n:%n?%?o? o:%o?%?d? d:%d?%?F? f:%F?%?t? t:%t?%?p? p:%p?%?b? i:%b?%?l? %l?] %?V?%V ?(%s/%S) %> (%P) "


# 3.381. status_on_top
# 
# Type: boolean
# Default: no
# 
# Setting this variable causes the “status bar” to be displayed on the first line
# of the screen rather than near the bottom. If $help is set, too it'll be placed
# at the bottom.
# 


# 3.382. strict_threads
# 
# Type: boolean
# Default: no
# 
# If set, threading will only make use of the “In-Reply-To” and “References:”
# fields when you $sort by message threads. By default, messages with the same
# subject are grouped together in “pseudo threads.”. This may not always be
# desirable, such as in a personal mailbox where you might have several unrelated
# messages with the subjects like “hi” which will get grouped together. See also
# $sort_re for a less drastic way of controlling this behavior.
# 
set strict_threads=yes


# 3.383. suspend
# 
# Type: boolean
# Default: yes
# 
# When unset, mutt won't stop when the user presses the terminal's susp key,
# usually “^Z”. This is useful if you run mutt inside an xterm using a command
# like “xterm -e mutt”.
# 


# 3.384. text_flowed
# 
# Type: boolean
# Default: no
# 
# When set, mutt will generate “format=flowed” bodies with a content type of “
# text/plain; format=flowed”. This format is easier to handle for some mailing
# software, and generally just looks like ordinary text. To actually make use of
# this format's features, you'll need support in your editor.
# 
# The option only controls newly composed messages. Postponed messages, resent
# messages, and draft messages (via -H on the command line) will use the
# content-type of the source message.
# 
# Note that $indent_string is ignored when this option is set.
# 
set text_flowed=yes


# 3.385. thorough_search
# 
# Type: boolean
# Default: yes
# 
# Affects the ~b, ~B, and ~h search operations described in section “patterns”.
# If set, the headers and body/attachments of messages to be searched are decoded
# before searching. If unset, messages are searched as they appear in the folder.
# 
# Users searching attachments or for non-ASCII characters should set this value
# because decoding also includes MIME parsing/decoding and possible character set
# conversions. Otherwise mutt will attempt to match against the raw message
# received (for example quoted-printable encoded or with encoded headers) which
# may lead to incorrect search results.
# 
set thorough_search=yes


# 3.386. thread_received
# 
# Type: boolean
# Default: no
# 
# When set, mutt uses the date received rather than the date sent to thread
# messages by subject.
# 
set thread_received=yes


# 3.387. tilde
# 
# Type: boolean
# Default: no
# 
# When set, the internal-pager will pad blank lines to the bottom of the screen
# with a tilde (“~”).
# 
set tilde=yes


# 3.388. time_inc
# 
# Type: number
# Default: 0
# 
# Along with $read_inc, $write_inc, and $net_inc, this variable controls the
# frequency with which progress updates are displayed. It suppresses updates less
# than $time_inc milliseconds apart. This can improve throughput on systems with
# slow terminals, or when running mutt on a remote system.
# 
# Also see the “tuning” section of the manual for performance considerations.
# 
set time_inc=250


# 3.389. timeout
# 
# Type: number
# Default: 600
# 
# When Mutt is waiting for user input either idling in menus or in an interactive
# prompt, Mutt would block until input is present. Depending on the context, this
# would prevent certain operations from working, like checking for new mail or
# keeping an IMAP connection alive.
# 
# This variable controls how many seconds Mutt will at most wait until it aborts
# waiting for input, performs these operations and continues to wait for input.
# 
# A value of zero or less will cause Mutt to never time out.
# 


# 3.390. tmpdir
# 
# Type: path
# Default: (empty)
# 
# This variable allows you to specify where Mutt will place its temporary files
# needed for displaying and composing messages. If this variable is not set, the
# environment variable $TMPDIR is used. If $TMPDIR is not set then “/var/tmp” is
# used. 
# 


# 3.391. to_chars
# 
# Type: string
# Default: “ +TCFL”
# 
# Controls the character used to indicate mail addressed to you. The first
# character is the one used when the mail is not addressed to your address. The
# second is used when you are the only recipient of the message. The third is
# when your address appears in the “To:” header field, but you are not the only
# recipient of the message. The fourth character is used when your address is
# specified in the “Cc:” header field, but you are not the only recipient. The
# fifth character is used to indicate mail that was sent by you. The sixth
# character is used to indicate when a mail was sent to a mailing-list you
# subscribe to.
# 


# 3.392. trash
# 
# Type: path
# Default: (empty)
# 
# If set, this variable specifies the path of the trash folder where the mails
# marked for deletion will be moved, instead of being irremediably purged.
# 
# NOTE: When you delete a message in the trash folder, it is really deleted, so
# that you have a way to clean the trash.
# 


# 3.393. ts_icon_format
# 
# Type: string (localized)
# Default: “M%?n?AIL&ail?”
# 
# Controls the format of the icon title, as long as “$ts_enabled” is set. This
# string is identical in formatting to the one used by “$status_format”.
# 


# 3.394. ts_enabled
# 
# Type: boolean
# Default: no
# 
# Controls whether mutt tries to set the terminal status line and icon name. Most
# terminal emulators emulate the status line in the window title.
# 
set ts_enabled=yes


# 3.395. ts_status_format
# 
# Type: string (localized)
# Default: “Mutt with %?m?%m messages&no messages?%?n? [%n NEW]?”
# 
# Controls the format of the terminal status line (or window title), provided
# that “$ts_enabled” has been set. This string is identical in formatting to the
# one used by “$status_format”.
# 
set ts_status_format="[`tty|sed -re 's,.+pts/,,'`]mutt@%h%r %f%?V?[%V]&?"


# 3.396. tunnel
# 
# Type: string
# Default: (empty)
# 
# Setting this variable will cause mutt to open a pipe to a command instead of a
# raw socket. You may be able to use this to set up preauthenticated connections
# to your IMAP/POP3/SMTP server. Example:
# 
# set tunnel="ssh -q mailhost.net /usr/local/libexec/imapd"
# 
# Note: For this example to work you must be able to log in to the remote machine
# without having to enter a password.
# 
# When set, Mutt uses the tunnel for all remote connections. Please see “
# account-hook” in the manual for how to use different tunnel commands per
# connection. 
# 


# 3.397. tunnel_is_secure
# 
# Type: boolean
# Default: yes
# 
# When set, Mutt will assume the $tunnel connection does not need STARTTLS to be
# enabled. It will also allow IMAP PREAUTH server responses inside a tunnel to
# proceed. This is appropriate if $tunnel uses ssh or directly invokes the server
# locally. 
# 
# When unset, Mutt will negotiate STARTTLS according to the ssl_starttls and
# ssl_force_tls variables. If ssl_force_tls is set, Mutt will abort connecting if
# an IMAP server responds with PREAUTH. This setting is appropriate if $tunnel
# does not provide security and could be tampered with by attackers.
# 


# 3.398. uncollapse_jump
# 
# Type: boolean
# Default: no
# 
# When set, Mutt will jump to the next unread message, if any, when the current
# thread is uncollapsed.
# 


# 3.399. uncollapse_new
# 
# Type: boolean
# Default: yes
# 
# When set, Mutt will automatically uncollapse any collapsed thread that receives
# a new message. When unset, collapsed threads will remain collapsed. the
# presence of the new message will still affect index sorting, though.
# 


# 3.400. use_8bitmime
# 
# Type: boolean
# Default: no
# 
# Warning: do not set this variable unless you are using a version of sendmail
# which supports the -B8BITMIME flag (such as sendmail 8.8.x) or you may not be
# able to send mail.
# 
# When set, Mutt will invoke $sendmail with the -B8BITMIME flag when sending
# 8-bit messages to enable ESMTP negotiation.
# 


# 3.401. use_domain
# 
# Type: boolean
# Default: yes
# 
# When set, Mutt will qualify all local addresses (ones without the “@host”
# portion) with the value of $hostname. If unset, no addresses will be qualified.
# 


# 3.402. use_envelope_from
# 
# Type: boolean
# Default: no
# 
# When set, mutt will set the envelope sender of the message. If
# $envelope_from_address is set, it will be used as the sender address. If unset,
# mutt will attempt to derive the sender from the “From:” header.
# 
# Note that this information is passed to sendmail command using the -f command
# line switch. Therefore setting this option is not useful if the $sendmail
# variable already contains -f or if the executable pointed to by $sendmail
# doesn't support the -f switch.
# 
set use_envelope_from=yes


# 3.403. use_from
# 
# Type: boolean
# Default: yes
# 
# When set, Mutt will generate the “From:” header field when sending messages. If
# unset, no “From:” header field will be generated unless the user explicitly
# sets one using the “my_hdr” command.
# 


# 3.404. use_ipv6
# 
# Type: boolean
# Default: yes
# 
# When set, Mutt will look for IPv6 addresses of hosts it tries to contact. If
# this option is unset, Mutt will restrict itself to IPv4 addresses. Normally,
# the default should work.
# 


# 3.405. user_agent
# 
# Type: boolean
# Default: no
# 
# When set, mutt will add a “User-Agent:” header to outgoing messages, indicating
# which version of mutt was used for composing them.
# 


# 3.406. visual
# 
# Type: path
# Default: (empty)
# 
# Specifies the visual editor to invoke when the “~v” command is given in the
# built-in editor.
# 


# 3.407. wait_key
# 
# Type: boolean
# Default: yes
# 
# Controls whether Mutt will ask you to press a key after an external command has
# been invoked by these functions: <shell-escape>, <pipe-message>, <pipe-entry>,
# <print-message>, and <print-entry> commands.
# 
# It is also used when viewing attachments with “auto_view”, provided that the
# corresponding mailcap entry has a needsterminal flag, and the external program
# is interactive.
# 
# When set, Mutt will always ask for a key. When unset, Mutt will wait for a key
# only if the external command returned a non-zero status.
# 
set wait_key=no


# 3.408. weed
# 
# Type: boolean
# Default: yes
# 
# When set, mutt will weed headers when displaying, forwarding, or replying to
# messages. 
# 
# Also see $copy_decode_weed, $pipe_decode_weed, $print_decode_weed.
# 


# 3.409. wrap
# 
# Type: number
# Default: 0
# 
# When set to a positive value, mutt will wrap text at $wrap characters. When set
# to a negative value, mutt will wrap text so that there are $wrap characters of
# empty space on the right side of the terminal. Setting it to zero makes mutt
# wrap at the terminal width.

# Also see $reflow_wrap.

# 3.410. wrap_headers
# 
# Type: number
# Default: 78
# 
# This option specifies the number of characters to use for wrapping an outgoing
# message's headers. Allowed values are between 78 and 998 inclusive.
# 
# Note: This option usually shouldn't be changed. RFC5233 recommends a line
# length of 78 (the default), so please only change this setting when you know
# what you're doing.
# 


# 3.411. wrap_search
# 
# Type: boolean
# Default: yes
# 
# Controls whether searches wrap around the end.
# 
# When set, searches will wrap around the first (or last) item. When unset,
# incremental searches will not wrap.
# 


# 3.412. wrapmargin
# 
# Type: number
# Default: 0
# 
# (DEPRECATED) Equivalent to setting $wrap with a negative value.
# 


# 3.413. write_bcc
# 
# Type: boolean
# Default: no
# 
# Controls whether mutt writes out the “Bcc:” header when preparing messages to
# be sent. Some MTAs, such as Exim and Courier, do not strip the “Bcc:” header;
# so it is advisable to leave this unset unless you have a particular need for
# the header to be in the sent message.
# 
# If mutt is set to deliver directly via SMTP (see $smtp_url), this option does
# nothing: mutt will never write out the “Bcc:” header in this case.
# 
# Note this option only affects the sending of messages. Fcc'ed copies of a
# message will always contain the “Bcc:” header if one exists.
# 
# On Debian systems, exim4 and postfix strip BCC headers by default. The above
# warning applies to exim3 users, see /etc/Muttrc.
# 


# 3.414. write_inc
# 
# Type: number
# Default: 10
# 
# When writing a mailbox, a message will be printed every $write_inc messages to
# indicate progress. If set to 0, only a single message will be displayed before
# writing a mailbox.
# 
# Also see the $read_inc, $net_inc and $time_inc variables and the “tuning”
# section of the manual for performance considerations.
