There has been a big move by spammers in the past year or so to use "botnets"
or "zombies" as has been referred to here, for sending spam. Spam blockers
used to rely partly on blocking mail from "open relays" or incorrectly
configured mail servers that allowed anyone to authenticate and send mail.
The recent closing of one of the big databases for tracking open relays,
signifies this shift. It's pretty impossible to keep a database of zombie
machines, as there are millions out there, that constantly change. New
technologies like heuristics are supposed to be the next way to fight this, so
filters can identify spam, the way you and I can, usually just by looking at
the Subject, and patterns in words, etc. PJ> To: shop-talk@autox.team.net>
