"User joe6pack is pumping out 100k messages/day. That can't possibly be valid; let's disable his -- and only his -- SMTP access. He can't spam directly via SMTP/25 connections, so we're good there." "User joe6pack's mail volume is two sigma above normal. Good thing our outbound mail spam scanning is much more stringent under these conditions." "User joe6pack doesn't know which of 50 machines behind his SOHO's NAT box sent the spam. Luckily, the username helps us/him track down the infected box."
