You can combine mutt and (x)emacs quite conveniently, in case you happen to use this combination of tools to send your mail.
First, let's make sure UTF-8 is used by both (to avoir horrible accent mis-rendering) by putting something like this in your .emacs/.xemacs init files
(setq locale-coding-system 'utf-8)
It may even help to add this
(when (not (string= (getenv "LC_CHARMAP") "UTF-8"))
(setenv "LC_CTYPE" "en_US.UTF-8")
(setenv "LC_CHARMAP" "UTF-8"))
Then, download mutt.el as available for example from http://www.lemis.com/grog/programs/emacs/emacs/mutt.el and change the pattern for mutt buffers to read
(defcustom mutt-file-pattern "mutt-a-z+-0-9a-f+-0-9a-f+-0-9a-f+"
"*Regular expression which matches Mutt's temporary files."
Put the modified mutt.el it in your emacs/xemacs load path, and make sure your load it by puttin
in your init files.
To avoid relaunching (x)emacs each time you write a message, it is better to turn your emacs into a server process; for this, add these two lines in your init files
Now, tell mutt to use (x)emacs as a mail client by adding this line in your .muttrc:
And that's it.... every time you send a message, you will be in a mutt-mode that has nice commands like
C-c tab mutt-goto-signature
C-c C-a mutt-attach-file
C-c C-b mutt-goto-body
C-c C-i mutt-goto-signature
C-c C-d C-c mutt-delete-old-citations
C-c C-d C-s mutt-delete-quoted-signatures
Just remember to exit the (x)emacs buffer using C-c #
