3 # mutt/sendmail – sendmail wrapper to enforce some checks on outgoing mails
4 #
5 # The script basically just creates a temporary file and then invokes any
6 # executable scripts in ~/.config/mutt/sendmail-checks.d in run-parts style.
7 # They receive the filename of a temporary file holding the message to be sent
8 # as $1, followed by all recipients as determined by mutt.
