Backscatter is not just ANY bounced email. Non-delivery notices are not bad either. A mail server sending a bounce notice because a message was malformed is a correct action to take. Sending a bounce notice because the message was infected has turned into a bad thing and is now considered backscatter. ================================= Kevin W.
