Unable to relay from a my SQL 2005 server with Exchange 2007.
Posted on 2009-04-16
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.
