IESG list. The chain: Spamassassin -> TMDA -> mailman moderation basically does the job just fine.
Oh, I hadn't realized that Spamassassin was in front. Yes, that should help a lot, since I expect that the contents of legit mail to IETF lists is rather unlike the contents of most spam.
On the other hand, I run the ASRG list, and I'm seeing several hundred spams a day land in the mailman moderation queue. If I don't clean it out a couple of times a week, the list of stuff to delete gets so big that my web browser times out trying to load it.
