Is this considered reverse NDR?

Hi guys,

Question: I have a user who is receiving A LOT of NDR messages (that are spam). The NDRs however are not being generated by our mail server. I believe what is happening is that our user is having their e-mail address spoofed by spammers and when their spam is sent out the NDRs that result from it are being sent to our user. Is this considered a reverse NDR attack and what can I do to help stop it?

I have Brightmail 6.0 installed which is catching a lot of these messages but our user's inbox is still getting flooded.

Ideas??

Thanks!
 
I'm just digging into exchange administration so there may be a smooth server side way to do this that I don't know about, but it should be easy enough for him to create a rule in outlook to move anything from postmaster@* to the deleted items folder.
