Relaying denied

The relaying denied error message is caused by the IP address of the machine you are connecting from, not being in on of the two following fields:

1.  'Permitted connections only from the following addresses' field on the SMTP Service | addresses page

2.  'The following addresses are from  Local domains' field on the SMTP Service | addresses page

To correct this add the IP address of the machine to one of the fields and click on the 'Add IP address' button.
