I second others' recommendations for sbl-xbl.spamhaus.org. 

The way I have it set up at my day job, I use MIMEDefang and do the 
blacklist check in filter_recipient(). It means the list gets checked 
once per recipient instead of once per connection, but it also means 
that I can set some addresses (like 'contact' and 'support') to not 
filter using the blacklist. The machine has a caching DNS server anyway, 
so no big deal on the DNS load. 

My Web page referenced in the bounce message given tells people that 
they can use the contact or support addresses to email us, if they 
happen to get on the list. So far, in a couple of years, that's only 
happened once (when an ieee.org mailserver got on XBL because a machine 
behind their NAT was spewing out viruses...)
