Hello all, currently we have an Exchange 2003 FRONT END server that does handles outside mail, OWA, and Active Sync. Why wouldn't we put a CAS server to do the same thing? I know we can do a EDGE server but if I have to open the ports for OWA, and Active Sync anyway why not in the DMZ rather than inside my network?
Note: that only Postini Spam Services can connect via port 25. Thanks!!
