I like the policyd-weight postfix filter... it sums up a score based on 
several conditions that you can set (dnsbl, bad smtp protocol, etc.) 
caches, results for those that hit you constantly, etc.  I probably get 
2-3 spam a day max.  Used to get 30-40.  And it does it all before 
accepting the message body which is nice.

You can also tell it just to put in a x-header with a score and pass it 
along untouched so users can do what they want using that info.
