here's the bl's that i am using with sendmail that would go into your siteconfig.mc file -- that through trial and error -- i have found have zero false positive hit rate... n.b. that the XXX.r.mail-abuse.com (RBL) & XXX.q.mail-abuse.com (QIL) bl's require that you to have a subscription to Trend Micro Advanced Email Reputation Services at
http://us.trendmicro.com/us/products/enterprise/ne twork-reputation-services/index.html -- you can get a free trial at
https://nssg.trendmicro.com/download/trial/trial-s ervices.php?id=66 --
make sure you select "Email Reputation Services, Advanced". you would then replace the "XXX" in the below with the activation code they would send you:

i also use the
http://hcpnet.free.fr/milter-greylist greylisting package as well as spamassassin with some custom score tweaks available at
http://iconia.com/user_prefs. all this keeps my mailbox as well as other users at a college radio station and a commercial asp with lots of public email addresses on their respective websites relatively spam free.
