While it's not free for larger volume/commercial use, Spamhaus ZEN (which includes the SBL, XBL, PBL, and now CSS DNSBLs) has been invaluable here. I've always scored on ZEN, but recently I began moving clients to a newer server where I am enforcing SMTP authentication. As a result, I am now able to block based on PBL listings. This alone has blocked about 80% of the spam outright at the SMTP session level that was previously coming in and then being filtered by SpamAssassin as well as ClamAV. -- Best regards, Robert Braver rbra...@ohww.norman.ok.us
