FWIW, we have an anti-spam list on our site that is used by a lot of other ISPs on the net. It contains all of the known Cyberpromo domains and IP address blocks, and a ton of other stuff. You can get our active list anytime by sending an email message to: spamlist@us.net The list is ready to load into sendmail 8.8.6 using the filter rules available at: http://www.informatik.uni-kiel.de/%7Eca/email/chk-newmap.html BTW, we will remove any entry in the file as long as the spammer agrees to sign and notarize a contract that establishes damages at $10,000 per incident if it happens again (and we WILL enforce the contract). If they are ISPs, I want to talk personally to the owner of the company. We don't put entries into the list lightly, and we don't remove them lightly either.
