Hello,
I'm running an exchange server 2003 SP1 on Windows 2003 SP1. We are getting mail message sent back. Why they're comming back ,I do not know.
Below are some examples of what the messages look like. Some of our emails go through and some don't.
Is there something that I need to set in Exch? Any feedback would be greatly appreciated.
