On the properties of your Send Connector have you checked that there is a Source Server? &nbsp;This should be your Exchange 2010 Server.<br />

I am trying to replace a Server 2003 SBS environment with Server 2008 R2 and Exchange 2010. I have migrated all of the mailboxes successfully to the new server and can receive email. But when I attempt to send, the email gets stuck in the &quot;Unreachable Domain&quot; queue with the error message &quot;A matching connector cannot be found to route the external recipient&quot;.<br />
<br />
I have a Send Connector configured with a * and a cost of 1.<br />
<br />
Any ideas on what to look at?<br />
<br />
Thanks
