Of the ones above, I only use spamhaus, combined with opm.blitzed.org &relays.visi.comi use the same ones as Patrick, but i also use the cbl (a component of the spamhaus xbl, perhaps the only one at the present time, but that could change.)
Mind if I ask why you don't use the sbl-xbl?BTW: I also use haebeas & bogons, but not really sure you would call haebeas a blacklist. :)
one thing i do is use opm.blitzed.org and cbl.abuseat.org at connect time.hosts on these lists are pretty much guaranteed to be open proxies orcompromised hosts, so listening to them at all is a waste of time. no needto wait until after RCPT TO: to 5xx, i just drop the connection.
I love opm.blitzed. I haven't tried cbl.abuseat.org. I'll have to check it out.
Also, I like sender verification, but that's me.i used it for some time, and reluctantly shut it down. blocked a lot of emailabuse, but too many false positives for my taste.
Could you go into more detail?I've only been using it a couple months, but I have a whole 1 false positive, and I'm not sure I'd call it a false positive. (Web page which sent e-mail and allowed anything in "from" address, but was password protected internal thing, so they were not doing sanity checking thinking it was guaranteed good e-mail.)
Maybe I have others I just don't know about? How many people send legit e-mail with return addresses which are bogus?
