smarthost

I have a postfix mail server that should relay all outgoing mail to an Exchange 2010 server (the Exchange box is my smarthost). I have administrator access to the Exchange 2010 system, but I'm not very familiar with it. How should I set up authentication on the Exchange 2010 system?

I guess I could add a standard user with a mailbox on the Exchange box, then configure my postfix box to log in to port 587 to relay mail. That option doesn't feel right -- it seems like there should be way to do server to server authentication, not just client to server authentication. Is there? If so, how would I set it up?
