FYI - I have been struggling sending mail through my exchange server for some time (I can receive / can't send). We have a Cisco PIX firewall protecting our network. Tonight I found the cause. You have to disable the "fixup protocol smtp 25" which is on by default on the PIX (OS version 6.3.5). Hope this helps.
