relays.osirusoft.com
-- has a feed from SPEWS, not everyone likes what that represents
dnsbl.njabl.org
-- very good, although slow to remove sites that fix things up
relays.ordb.org
-- pretty conservative, no false positives
list.dsbl.org
-- extremely good, but I get a few false positives from time to time
multihop.dsbl.org
-- a bit too severe for my tastes
blackholes.wirehub.net
-- seems ok, but as it's at the end of my list it doesn't have the
chance to catch much, I suppose.
I've heard favourable reviews of opm.blitzed.org,
blackholes.five-ten-sg.com and proxies.relays.monkeys.com
Before you start using remote blacklists, you should set up your own
restrictions, blocking on garbage HELO, envelope forgeries and the like.
