I have not found any information on locking down Exchange 2007 SMTP from open relaying of messages.
Unlike Exchange 2003, you do not install SMTP on the server. Exchange 2007 has it's own SMTP agent.
I have users sending messages using SMTP and port 25 is NAT'ed (mapped) to another port on the internet router.
Does anyone have any suggestions or information to lock down SMTP on the Exchange server. It is a stand alone machine with no external servers or hubs.
Thanks,
Mark
