This part of the faq should be altered: I've stumbeled over teh same thing
too

I'm doing nearly the same thing:

My solution:

1) No .forward
2) .procmailrc-receipts taking care of the mailing list entries which I
don't want to forward:

:0H
*^X-Mailinglist:
!local-maililnglist-user

Note the lacking of the 'c' flag in the header: those mails are moved, not
copied. I use another local user for the mailing list. Note that not all
mailing lists use the 'X-Mailinglist flag

3) A receipet at the end of .procmailrc, that with a list of exclusive regex
staements filters out which messages I want to forward, here a simplified
version:

:0Hc
* !Return-path: \<nonforward-local-user\>
* !Return-path: .*\my-employer\.com
* !From: me\@my-employer\.com
* !^FROM_MAILER
!me@???

# Explanation:
- the 1st receipte filters out system-internal mails from a dedicated user
from being forwarded
- the 2nd and third lines filters out mails from my employer domain
- the 4th line filters out mails from myself to stop infinite loops

This seems to work qiute well.
