My CustMapsList is bl.spamcop.net:0,combined.njabl.org:0,sbl-xbl.spamhaus.org:0 And I run greylist as a predata filter. And my postdata AV filter performs some checks on the ClientDomain. Together, they catch almost all spam (and viruses). As to dns blacklists: spamhaus and njabl are virtually 0 false positives (provided you give auth'ed dialup users a way to bypass them). Spamcop requires some whitelisting from time to time, but not too much. I had to stop using sorbs and blackholes.five-ten because of too many false positives. Anyway, I think you have to experiment with dnsbl: no one is the best for everyone, it depends on your specific situation (geographic location, traffic patterns etc.).
