How to block incomming Delivery has failed messages for a specific user in exchange 2007
Posted on 2014-08-26
I have a user who's email address has been hijacked and is being used for spam.. it is not being sent using our system, but she keeps getting Undeliverable bounce backs (Delivery has failed messages). I created a local rule to permanently delete the messages, but it is still causing issues on her Iphone.. they do delete after a while, but not quick enough. I would like to use a transport rule to take care of the issue.. Every couple of weeks I will turn it off to see if they are no longer using her address..
I have setup several different rules, but none of them seem to work...
sent to = her account
subject contains or body contains = "Delivery has failed" (a separate rule) or "Undeliverable"
There must be a way to set this up to stop these messages..
any help would be great.... thank you in advance experts
