if it's a Real MTA, then kicking back a 550 will -- probably -- have the MTA trying to return the message to the "sender". there will probably be backscatter. if it's NOT a real MTA -- if it's a spam proxy or a virus trying to send the message -- then kicking back a 550 will -- probably -- have the message dropped on the floor. there will probably not be backscatter. so i think you're both right, more or less. rp rick pim [EMAIL PROTECTED] information technology services (613) 533-2242 queen's university, kingston ----------------------------------------------------------------------- "Hmm hmm hmmm....
