Backscatter

Backscatter consists of incoming spam, caused by malicious entities forging email addresses for your domain. Backscatter occurs when a mail server accepts a forged message, that it subsequently refuses to deliver due to forgery.

This refusal, causes the receiving mail system to send a Delivery Service Notification (DSN) to the forged message Return-Path (your mail system). Backscatter may be avoided by rejecting these types of messages at the border of the MX.

Abusix Mail Intelligence includes a dataset that contains IP addresses of systems that have sent backscatter to our traps, which you can use to filter these messages.
