You can run procmail in "filter mode" and pipe it each mail that you wish to filter individually, but you must keep track of which mails have been piped to procmail and remove them/mark them 'processed' yourself, via shell scripts etc.
Make sure your procmail recipe(s) deliver to a sensible location. -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe". Trouble? Contact listmas...@lists.debian.org Archive: http://lists.debian.org/20120705124158.GC32553@debian
