I have just taken over the administration of a server and it has Exchange Server 2003 SP2 on Windows Server 2003 Standard. This is not a public server (not public IP address for it).
The Exchange Server is sending out email (SMTP) and pulling email from Postini for inbound. Unfortunately I am not extremely familiar with Exchange Server and I have never used Postini before.
It looks relatively straight forward; however, I am unsure of how Exchange knows to get the email from Postini or how Postini sends the inbound emails to it.
1. Can you tell me how to determine the flow? Outbound, inbound etc.
2. If I were to move the inbound portion to another provider, say GoDaddy; how would that be done?
3. What, in your opinion, is the best reference book for administrating Exchange Server 2003.
Thank you for your time and help.
