Exchange 2007 Error – Mail submission failed: Error message: The SMTP host was not specified

We are helping out a consultant that is working with a new client that had a previous IT company drop a $15K box down and configure it with ADDS and Exchange … sorta.

For some reason, e-mail stopped flowing at 05:00Hrs this morning.

Once the send connector was created, e-mail started to flow as expected.

The box is running Windows Server 2008 with Active Directory, DNS, DHCP, File Services, and Exchange 2007.

How was it working before without the outbound mail configured?

Nat,

Therein lies the mystery. We are not certain where in the whole scheme of things the connector was removed.
