Would there be anything in the email header which may make the NDR's unique? You might be able to generate a rule based on the that unique info.

I have a user that is getting bombed by NDR's that are not originating from him. It seems that he's the lucky recipient of some spammer using his account as a "sent from address". Is there any way to stop this or is he stuck with it? Exchange 2010, Outlook 2007 Thanks as always!
