Exchange 2003 SBS - Mail relay, outward e-mail

Hi

I'm having a problem with the set-up on my SBS2003 Exchange Server. Bizarrely, I can receive e-mails, so the DNS record is properly set-up and port 25 is correctly open.

The recipient policy on the SMTP server is correct, so I know that the e-mail address is valid. I have also verified the domain name via SMTP Virtual Server> Delivery> Advanced> Check DNS.

However, in the default SMTP Virtual Server queue the outward e-mail simply fails until eventually Exchange gives up.

I have used http://www.zonedit.com/smtp.html to check the SMTP and the returned error is 550 5.7.1 Unable to relay for <myemail@mydomain.com>

Does anyone have any ideas?

Thanks in advance
