This begs the question, why can you NOT afford to filter some lists?

I personally cannot imagine a situation where this would be so.

I've found that since we implemented gray-listing and spam-assassin 
and ClamAV on my server, I get maybe one Spam mail slipping through 
to mailman each month. Most times, it is completely spam-free and the 
only moderation request I get are for members trying to post to a 
member's only list from an alternative e-mail address.

Before we did all of this, we were getting many thousands of spam 
mails each day. Right now, those spam mails are still hitting the 
server but the vast majority are never even received because 
gray-listing derails about 80 to 90% of them. Of those that do get 
past that, most are then correctly identified by spamassassin for 
what they are.

You really should use the power of MTA filtering, it will save you a 
lot of frustration. At the very least, use gray-listing because the 
vast majority of spam simply won't be resent when a deferral response 
is sent from your MTA to the sender.
