that'd use ~/.procmailrc if any; if you want procmail to deliver as if msgs 
were from fetchmail, that's fine - though I'd rather set -Y:

% formail -s procmail -Y .procmail/debian-list.rc < Mail/inbox

assuming Mail/inbox is in mbox format, of course; if the *.rc is a generic
filtering recipes set, you may want to use the -m flag instead:

% formail -s procmail -m -Y .procmail/debian-list.rc < Mail/inbox

but me careful that debian-list.rc doesn't have a rule that delivers to
Mail/inbox ;)
