Client cant E-mail one Domain (Exchange 2003)

By ryan1234bishop ·
Good day all

I have one client who cant E-mail a Domain. When they try they get no bounce backs and no messages get received on the other end. I did an SMPT test and below were the results

OK, connected to
< 220 Microsoft ESMTP MAIL Service, Version: 6.0.3790.4675 ready at Fri, 1 Oct 2010 14:20:38 -0230
< 250 Hello []
< 250 2.1.0 OK
> RCPT TO:<>
< 550 5.7.1 Unable to relay for

Besides doing that test I have no idea where to start. Any pointers\experience about this topic you want to discuss

Is the receiving email address correct?

Does it occur when attempting to send to known email addresses at
It could also be the mail server at that is down or offline for some reason. From the header you posted, the email address of the receiver does not exist or doesn't have an inbox on the mail server at the Newfoundland, Canada offices.
