It's *really* ment to be use from inside mutt... but to use it from a command line you can do it like this: mail2procmail < some.mail.letter The needed lines to your muttrc is something like: macro pager \Cf "|~/path/to/mail2procmail\n" macro pager \Cf ":set pipe_decode\n|~/path/to/mail2procmail\n" This will binds -f to execute mail2procmail... mail2procmail will exec generateproc.pl to generate a file called ~/.procmail/m2proc.rc. in your .procmailrc you should have something like "INCLUDERC=~/.procmail/m2proc.rc" and everything should work.
