I'm sure there must be an answer for the following puzzle, but why is it at all difficult to track down spammers? After all, they are advertising things that they very clearly tell you how to buy. (This applies to advertising spam, not to viruses or worms).One of the developers of JunkSpy has told me that it is not difficult to fake most anything in the headers,including most of the route the mail travelled on its way to you. This is whatcan make it hard for law enforcemement agencies to track this stuff down, in the tiny minority of cases where they may bother to do so. Still, it should sometimes be possible for recipients to attempt this on their own, and file an abuse report wherever that may be appropriate.Harry Binswanger hb@xxxxxxxx
