Let me explain my situation as this is strange and I am baffled and new to this organization. I work for a University and we have tons of email servers on campus. Everyone has a @university.edu email and account, but all the departments / colleges under the main university do their own thing.
So that means I work for @dpt.university.edu and we have our own Exchange 2010 server. Oh, and @university.edu is a Linux free something or another.
We have been delegated the sub domain and manage our own dns they are secondary. We have only 1 smtp on people's accounts (dpt.university.edu) but when people here send mail it is @university.edu. When people respond it goes to @university.edu. I have been having people configure a forward rule from university to dpt.university.edu and that works.
So what am I missing? Where else should I be looking? I have not had to manage exchange since 2003.
Thanks
