Therein lies the problem with his approach; he can only tune his message to get past his own filters. Assuming most people have similar mail corpora (as in the case for site-wide Bayes setups), his approach may reduce Bayes' effectiveness some. I'm not worried about it. I quesstion some of his motives and logic (paraphrasing: "let's reduce filter effectiveness in order to shift focus to other ways of fighting spam like e-postage and web-of-trust".) The way you stop spam is by denying spammers access to the internet and by securing resources so they cannot be abused to send or receive spam. Discovering the social, legal, economic, and technical means to do that are left as an exercise for the student. It's well known that filtering is *only* useful for keeping one's inbox uncluttered; it does nothing to interdict the flow of crap from upstream. You want to put a serious dent in spam? IDP broadband providers that give their customers direct access to port 25 on remote systems by default. Spam from AOL dropped to almost nothing once they did that. It's not trivial to filter outbound port 25 traffic but if you want to provide large-scale broadband access, it's mandatory to curb abuse. It takes money, expertise, and most importantly, the corporate will to be a good net neighbor and take responsibility for their users' actions. Most broadband providers have all but the latter; an IDP gives them incentive to get it or lose the rest. -- Bob ------------------------------------------------------- This SF.net email is sponsored by: Perforce Software.
