New Spam Zombies Use ISPs' Mailservers

that the new
spam zombie PCs are no longer acting as their own mailservers, but cooperate with the ISPs' recommendation that instead of running your own mail server, to use theirs instead."
Now just force SMTP Authentication on the ISP side. They didn't implement it just for fun. Everybody put his login/password in the pop3/imap textboxes, just put your login/password in the smtp textboxes. Won't kill anyone.
Problem instantly resolved.
