-# ack-recipients – require double-checking of some recipients
-#
-# refuse to send a mail as long as recipients listed in ~/.mutt/ack-recipients
-# are not individually "signed-off" by adding their e-mail addresses to the
-# X-Acked header. This header is removed from the mail before it is sent.
-#
-# The file ~/.mutt/ack-recipients stores sha256sums of lower-cased e-mail
-# addresses (no newline) instead of the addresses themselves as a measure to
-# protect privacy. You can get new lines like this:
-#
-# printf my.new@e-mail.addre.ss | tr '[[:upper:]]' '[[:lower:]]' \
-# | sha256sum | sed -e 's, .*,,'
-#
-# E.g. my address (see below) will become
-# 84d5b33c9376f67274c2ec9ce0e03b6973fb8bc943ebd7abb470c903c47e00f4
