I uploaded a patch to the SF bug tracker today that adds support for doing SpamAssassin (http://spamassassin.taint.org/) checks to the mailman message pipeline:
http://sourceforge.net/tracker/?func=detail&aid=534577&group_id=103&atid=300103This will contact the spamd daemon to score the message. If the message gets scored above one threshold, it gets discarded (this defaults to 10, but can be customised in the mm_cfg.py file). If the message scores above another lower threshold, it gets held for moderation (this defaults to 5).
I wrote this to try and reduce the number of messages held for moderation. I wrote it for mailman 2.0.x (as that is what I am using at the moment), but it should be fairly easy to update for 2.1.
It might be worth using on the python.org mailing lists ...
James.
