I find spamcop to be very reliable, and the basis of many actions. Spamcop is a perfect example of garbage in / garbage out. I've had a number of servers in spamcop's blacklist for the following reasons: 1) Local user misinterprets headers and reports one of our own MX's thinking it generated a spam he/she received. We get blacklisted. 2) Remote user gets the same message a few times from one of our users (some tax related documents) and for reasons unknown to us, reports it as spam, and we're blacklisted. 3) Local user runs a mailing list on one of our servers and leaves posting open (yeah...that was a bad idea, but lots of lists still do it). List gets spammed. A list member reports our server, causing it to be blacklisted. This one is actually listed right now, and we've gotten a few "why can't I send email to ...?" questions from other customers on the same server. The idea of a spam blacklist with an army of contributors is appealing. In theory, it could blacklist large numbers of spam sources, perhaps before they get a chance to hit your servers...but the reality is an army of idiots turning a good idea into an unusable mess. Some sort of hybrid of spamcop with dsbl, where those who screw up have their contributing rights revoked would be far more interesting. There also needs to be some method for intervening when someone screws up rather than having to just wait out expiration of a listing that should never have happened. -- ---------------------------------------------------------------------- Jon Lewis *[email protected]*| I route System Administrator | therefore you are Atlantic Net | _________ http://www.lewis.org/~jlewis/pgp for PGP public key_________
