If you must have port 25 opened on the PIX, then this seems to be an Exch 5.5 question.

To make sure that relaying is not allowed by your 5.5 server, open Exchange admin, goto connections- Internet Mail Service-routing

click "routing restrictions" and make sure that only:

"Hosts and clients that successfully authenticate" is check, and nothing else.

You're done.
