I'm not sure you can attribute that entirely to the latest worm to attach the Microsoft virus, Windows. Of 13,503 rejected attempts on our primary mail server yesterday, 6,557 were for no rDNS, 1,220 from bad HELO (attempting to masquerade as one of our servers), 1,599 from bad MAIL FROM (no ``A'' or ``MX'' records for the domain part of the alleged sender). Our backup mail server rejected 26,965 attempts, 6,181 for no rDNS, 6,710 bad HELO, and 1,631 for bad MAIL FROM. I'm seeing about 300 incoming worms a day just to my personal addresses, almost all of which claim to be patches for Windows.
