Hi all,

I recently added a new domain and cannot send email to any of the users 
I have added.  I get the following error:

-----8<-----

    ----- The following addresses had permanent fatal errors -----
<ln.admin (at mark) mydomain.co.uk>
     (reason: 550 5.7.1 <ln.admin (at mark) mydomain.co.uk>... Relaying denied. 
Proper authentication required.)

    ----- Transcript of session follows -----
