Bounceback emails for messages we did not send

=========
QUESTION
———
All of a sudden this morning we are getting tons of bounce back email messages for emails we did not send. What is going on? 

 

=========
ANSWER
——— 
If these are bounce back messages, or email delivery failures for messages you truly did not originally send, the term used to describe this phenomenon is “Backscatter”

See the links in the REF section at the bottom of this article for further information. 

We cannot do anything to block or fix this issue, as they are legitimate bounce backs. 
If the problem is severe (in the tens of thousands of messages) then we may take the step of blocking the IP address.
