How to Setup Windows 2003 and Exchange 2003 SMTP Relaying

I don't see this referenced enough in the forums and wanted to make sure people can find this easily and quickly. It can help you diagnose cases where Exchange does not send email, autoresponders, etc.

By default Exchange 2003 is set up too deny relaying from any IP address (including your intranet).

So, theoretically, if you set up eSupport on IP 192.168.1.80 and Exchange resides on 192.168.1.25, you need to explicitly tell Exchange that any SMTP connections originating from 192.168.1.80 are allowed.

8 Simple Steps:

1. Log into Exchange 2003 server (192.168.5.25 in my example above) and start Exchange System Manager.
2. Expand the organization_name object, and then expand the Servers node. Expand the server_name object of the server on which you want to control mail relay, and then expand the Protocols node.
3. Expand the SMTP node, right-click the virtual SMTP server on which you want to control mail relay, and then click Properties
4. Click Relay.
5. In the Relay Restriction dialog box, several options are available. The Only the list below option is enabled by default; the list below this option is empty.
6. Click Add. Enter the IP address of the server running eSupport (192.168.5.80 in my example above).
7. In the Relay Restrictions dialog box, click OK.
8. Click Apply, and then click OK in the Default SMTP Virtual Server Properties dialog box.

Good luck. I hope this helps someone.
