I would use spamhaus for MTA reject and spamcop in SA. I've also been evaluating a very interesting new RBL for several weeks called the "ivmSIP" rbl. Its designed to work after RBLs like spamhaus to catch what they miss and it works quite well so far. It's catching about 30% of the mail that makes it past both spamhaus and spamcop (and of course some of that mail is actually not spam :). The web site for the new list isn't ready yet but you can ask for a trial feed by emailing Mr. Rob McEwen at rob@invaluement.com Received on Tue Oct 9 14:09:14 2007
