Mutt is a small but very powerful text based program for reading and sending electronic mail under unix operating systems, including support for color terminals, MIME, OpenPGP, and a threaded sorting mode.

Note: This manual page gives a brief overview of the mutt executable command line options. A copy of the full manual is located in /usr/share/doc/mutt, in text, HTML, and/or PDF format. Please refer to the manual to learn how to use and configure Mutt.

-A alias
Print an expanded version of the given alias and exit.
-a file ...
Attach a file using MIME. Separating file and to-addr arguments with “--” is mandatory. For example:
mutt -a image.jpg -- to-addr
mutt -a img.jpg *.png -- to-addr-1 to-addr-2

The -a option must be placed at the end of command line options.

-b bcc-addr
Specify a blind carbon copy (BCC) address.
-c cc-addr
Specify a carbon copy (CC) address.
-d level
If Mutt was compiled with +DEBUG log debugging output to ~/.muttdebug0. Level can range from 1-5 and effects verbosity. A value of 2 is recommended.
-D
Print the value of all configuration options to stdout.
-E
Edit the draft file specified by -H or include file specified by -i during message composition.
-e command
Specify a configuration command to be run after processing of initialization files.
-f mailbox

-F rcfile

-H draft
Specify a draft file which contains header and body to use to send a message. If draft is “-”, then data is read from stdin.
-i include
Specify an include file to be inserted into the body of a message. Ignored if -H is set. If include is “-”, then data is read from stdin.
-m type

-v

None. Mutts have fleas, not bugs.

Suspend/resume while editing a file with an external editor does not work under SunOS 4.x if you use the curses lib in /usr/5lib. It does work with the S-Lang library, however.

Resizing the screen while using an external pager causes Mutt to go haywire on some systems.

Suspend/resume does not work under Ultrix.

The help line for the index menu is not updated if you change the bindings for one of the functions listed while Mutt is running.

For a more up-to-date list of bugs, errm, fleas, please visit the mutt project's bug tracking system under https://gitlab.com/muttmua/mutt/issues.
