I've begun using junkfilter, a massive procmail script available from
http://junkfilter.zer0.org .  It's pretty effective at catching spam,
and I think there's an option to use the RBL to catch open relays.  

My only complaint is that each message spawns a seperate procmail
process, each of which takes about ten seconds to complete on my
P-200, and running N messages through procmail at once (i.e. after
fetching them with fetchmail) raises my process load to about N/2.
I've avoided this my putting the junkfilter at the end of my
.procmailrc instead of at the beginning, since I don't get much spam
on any of my mailing lists.

Hope that helps.
