I use fetchmail->procmail->mutt programms to all my mail. Some of mail generated automatically and some people not smart enough, so I would like to reformat mail body with some script.
My best guess is that I should do it with procmail. But I found no such rule, best thing I found is possibility to pipe mail to programm. Of course, I can resend it with flag that no futher formatting needed, but it does not look like right solution.
EDIT: Just discovered
maildrop. Maybe, it is simpler to do my task with it?
