I have a file that will cause XXX virus scanner to crash. Does the SMTP agent view that as a reason to reject the email or does it pass it through? If it does a temporary rejection message because of some internal failure, the infection rateof these messages becomes very low. Not sure how virus scanners + SMTP servers interact with regards to tradition SMTP errors. It would be an effective anti-cleanup method though. -- Chris Green <cmg@dok.org> Fame may be fleeting but obscurity is forever.
