Cannot send outbound SMTP - 28.Aug.2006 10:42:45 PM

I installed an Exchange 2007 Edge and a HUB\Mailbox server into an Exchange 2003 org for migration and coexistance testing. I installed the send\receive connectors and can send email between 2003 and 2007, as well as receive email from the internet. However, since the installation, I can no longer send outbound SMTP messages from EX 2003 or EX 2007. The error message received is:

The following recipient(s) could not be reached:

You do not have permission to send to this recipient. For assistance, contact your system administrator.
<servername #5.7.1 smtp;550 5.7.1 Unable to relay for..>

Any help would be much appreciated.

Thanks
