my basic problem is, that i want to forward mails from one mailing list to another (on both lists only subscribers can post): the setting is as follows: there is an "announce"-list and a "users"-list; mails going to the "announce"-list should also go to the "users"-list, so people don't have to subscribe to both lists the subscribers to both lists overlap, but there are a lot of users subscribed to only one of them.
There is a patch <http://sourceforge.net/tracker/index.php?func=detail&aid=1220144&group_id=103&atid=300103> which would allow you to specify the "announce" list in the "users" list's accept_these_nonmembers. This would solve your problem and is a candidate for inclusion in Mailman 2.2, but in the mean time it is still a patch which you don't want to do.
so my second thought was to auto-accept postings to the "users" list which has a special header-field (i thought that the "List-ID"-field would just be ok for my purposes). unfortunately i found that this wasn't possible (i am running debian and tried both 2.1.5-8sarge2 (which is basically 2.1.5 with some cross-site-scripting security issues fixed) and 2.1.8)
You could do this with a custom handler which is not a patch in that once it is implemented and installed, it survives upgrades. See <http://www.python.org/cgi-bin/faqw-mm.py?req=show&file=faq04.067.htp> for info on custom handlers and see Mailman/Handlers/Approve.py for details of what needs to be done to accept a post based on a header - basically, recognize the header and set the 'approved' flag in the message metadata.
