I'm running Exchange 2003 on a Windows 2000 server. Our queue usually have a few thousand messages "Delivery Status Notification (failure)" bound for spammers. They guess names and tack it on our our domain name. These addresses don't exist and Exchange wants to send a message back. These sit in the queue until they time out. How do I not send replies to bad email addreses?

This is not as specific as you wish but:

Security hardening exchange servers:

Tarpitting

Consider Forefront for exchange, or Exhange Hosted Services for delux email 'cleansing' from microsoft.

Recipient filtering would be your option here:

However if you are on Windows 2000 then this can actually expose your server in other ways, as you cannot tarpit. You would need to use a third party application to do recipient filtering - I have used Vamsoft ORF for that in the past.
