Except that "about selling and/or buying products and/or services" is a poor definition of spam. There's plenty of non-spam mail that's about commerce, and plenty of people who _want_ to get the email equivalent of their local store's coupon flyer, or whatever. There are really only two ideal spam indicators: (1) Who sent it. (2) What proportion of the people who got it, didn't want it. Unfortunately there's no way to directly apply either of those criteria. Razor and DCC are making a stab at (2), but they can't really succeed because (a) only the people who didn't want it will bother to speak up, and (b) some number of accidental or intentional false positives are always going to end up being reported. DNSBLs try to address (1) by using "where it came from" as an approximation, but if they're broad enough to be very effective, the cost is a lot of collateral damage. And of course both of those approaches are reactive rather than proactive. ------------------------------------------------------- This sf.net email is sponsored by:ThinkGeek We have stuff for geeks like you. http://thinkgeek.com/sf _______________________________________________ Spamassassin-talk mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/spamassassin-talk
