The problem here is you were not rejecting.. you were bouncing.. there is a HUGE DIFFERENCE. With a 5xx reject you tell the MUA/MTA you are not accepting the message for delivery and why, you do NOT generate a bounce. (yesyes, I know if the IP happens to be a valid MTA it may or may not generate a bounce, that is a different situation altogether though and IMHO a rare one where you do nto control both MTAs and can fix it anyway). Bouncing virus infected email (or spam for that matter) makes absolutely NO sense.
