There are various ways to achieve this, but it depends on the problem being addressed as to the solution I would recommend.  

I am not a great fan of using NDR's.  Best not to accept the message in the first place: Reasons: (1) Extra traffic is generated in sending NDR's which can be used against you to launch a DOS attack.  (2) If you send as little as one NDR to a honeytrap then you can be blacklisted.  You can't hide behind an alias as the block is against your IP.  (3) By accepting the message you need to have an "audit trail" of the fate of the message and if someone claims you have received a message that has some kind of contractual weight to it then you need to fish out the NDR which is elsewhere in the log - if you reject it then the log of the entire transaction is self-contained.

However, to attempt to answer your Q.  If the problem is someone sending to an unknown mailbox in your domain then you could have a catchall alias setup which funnels everything into a junk mailbox.  This mailbox could then have an Auto Responder setup on it which sends the NDR.  You can then have a mechanism for clearing out the mailbox.

If you are going to do it in the way suggested the catchall mailbox you use could be setup with a Restriction on it (Quota or Account is not allowed to receive messages from outside world).  Use the relevant RSP file in the \mdaemon\app folder to tailor the message sent back.
