Combing through many free domain blackhole lists the following are relatively extensive, and are readily maintained.
combined.njabl.org
list.dsbl.org
dnsbl.sorbs.net
spam.dnsbl.sorbs.net
Using these blacklists in your sendmail configuration can reduce the spam received from the most common and prevailing sources. Combining these active spam prevention measures, with passive techniques spam can be greatly reduced. Passive spam prevention includes blackhole lists that are not controlled by you. You can also implement graphical active spam filtering using Mozilla Thunderbird via filters.
