Looking at 100,000 messages in the database I get good hits on sare_unsub and 
the various sare_html. I also get good hits on the kam list 
(http://www.peregrinehw.com/downloads/SpamAssassin/contrib/KAM.cf)
and razor.

I added the following for some blacklists that I didn't see included with 
spamassassin. Play with the scores if you need to;
