I use MailScanner to to A/V scanning and spam control and it can be
configured to send a reject back to the sender of a virus infected
message. But in the general case it is a bad idea since most of what
you'll see will have a forged envelope sender. So any notice you send
back is unlikely to reach the real sender and winds up just being an
annoyance to some innocent party. During the recent Sober outbreak I was
getting about 30 reject warnings an hour from all over the place. Given
that I don't have any windows boxes and thus could never have been the
source of a Sober infected email it was just a major annoyance.
