Ok, I know this is going to be a simple fix, we have a exchange server which has a basic whatever.com email address but then we havea seperate server which needs to recieve emails through the exchange server. The second server is servername.dev.whatever.com. Since the emails on the second server are not in AD we get a NDR. How do we foward these.

I think the answer was to create a Internal accepted domain and then create a send connector.
