Spam alerts have a well defined format and syntax, and specific capabilities. One capability they do not have is to process alerts of the form "New spam joint XYZ has announced that it will be sending spam from randomly generated domains with the following kind of pattern in the message header". Thus L-Soft does not have the capability to do this without a code change. As a matter of fact, the spam joints are going out of their way to prevent filters from identifying their spam as spam. IEMMC is a first and I am a bit skeptical about it having any long-term value. >Given that Agis, a not so small backbone ISP, delegated SPAM >responsibility to IEMMC, it would seem that IEMMC is (at least in Agis' >eyes) going to uphold their stated conditions and mechanisms.

I have heard a rumour that there is a lawsuit or settlement (can't remember which) in progress between Agis and its first-tier provider and that this will soon become a non-issue :-) Anyway, the spam detector is not designed to do pattern filtering. Pattern filtering is explicitly something we did not want to have, both because it is easy to program around for the spammers and because it raises legal issues along the lines of the Prodigy lawsuit. The spam detector rejects messages that have been massively cross-posted. By definition these messages are out of topic in the vast majority of the target lists. No judgment is made on the contents of the messages, merely on their distribution method. The spam filter works equally well for your average "Make Money Fast" plan and for racist propaganda or "God loves you" broadcasts. Filter based detectors typically let racist propaganda through because they were not programmed to detect it. If "X-Advertisement" becomes a standard, it will be another thing, but right now it is just the latest finding of an ISP that is desperate to get out of the hole it has dug for itself. Eric
