I think both Y!Groups and Google Groups have separate handling of mail moderated for spam reasons, not sure how easy that would be to set up with mailman. That way, you can say only digest the spam ones, while forwarding the regular ones.
Agreed, the best bet is to do more smtp time blocking, so you don't have to deal with the spam even getting in the queue. The exact features of doing that will vary depending on your spam load and what you can actually do with your server, of course. Locking down lists to only posts from users will probably do enough for most smaller systems that don't have to deal with drive by signups (though, moderating joining goes a long way to fixing that, also). Our spam system definitely tries to understand forwarders and not penalize them, but its a hard problem... and wrapping them in a moderation message definitely makes it harder for the normal forwarding rules... if you feel Gmail is penalizing for these, please send me some examples off-line and I can have the spam team take a look and see if there is a good way to handle these. With Google Apps domains, you can certainly add various whitelisting rules to ensure the mail gets through. We've debated what simple things we could add to the consumer settings to help in these situations, though this is yet another one.
