Unable to relay from a my SQL 2005 server with Exchange 2007.

We are trying to relay messages from my SQL 2005 server.   When I send to an address that is part of the domain the relay works.  But if I try and send outside the domain I get the following error:

SMTP Error:  Source: null  Description:  The server rejected one or more recipient addresses. The server response was: 550 5.7.1 Unable to relay

We have tried to work with the connector but is seems to still give us this error.

Does anyone have some insight on how I can troubleshoot this issue.
