Speed and efficiency. Very convenient keyboard only use. Highly configurable and scriptable. Available from anywhere with ssh.

mutt does many things out of the box that other programs cannot do or just with plugins and/or inconveniently hidden functions. Some examples of things I frequently use:

- bouncing mail

- re-send incoming email (after editing it)

- changing headers of composed emails on the fly

- show (only) certain headers by default

- using your editor of choice for composing mails

Why do you need to frequently change email headers?

Examples:

- Add "Approved:" headers for moderated/closed mailing lists

- Add or remove In-Reply-To headers as needed (remove if I reply to an old mail but it has nothing to do with the thread; add if I reply to a mail from a mailing list that I don't have any more but I have the message ID from an archive)

- Change the From address.
