how do I add an NDR for an existing mailbox or auto reply for a noreply@

Exchange 2007 - Outlook 2007
I need to create a for some outgoing emails for part of our internal process so the client cant respond directly in email.  The app should send directly via the server but it doesnt so i need to create a work around using outlook.

I tried to simply type in the nopreply@ in the from line in outlook but that wouldnt let me.  So i created a noreply mailbox and gave send as permissions.  that works but then it also allows inbound responses.  so how do i block the inbound mail with a NDR or send a autoresponse that says politely this is not a valid address.  out of office notice is not good enough.  i tried a server side rule but that wont send a response.

Basically create a new receive connector, set to externally configured, ensure it is not accessible from outside world and point your application towards it. It will relay as any email address.
