You strip the attachment you are still sending messages that you don't need to and shouldn't, and would still be participating in sending NDR's to people that should not be getting them. Recipient filtering stops that and lessens the load on your server and bandwidth.

I'm using Exchange 2003 and am trying to keep my domain from participating in NDR flood attacks. I've identified two possible methods: NDR attachment stripping, or recipient filtering paired with SMTP tar pitting. Any preference as to which is better, or are there other methods to fight this crud? Thanks in advance, Kyle B.
