The following error will be bounced back to a sender if the Email Relay address the sender is trying to send to hasn't been fully configured as per our exact setup instructions:

"Reason: error message 553: Sorry, that domain isn't in my list of allowed rcpthosts (#5.7.1)"

This usually occurs when your POP3 mail client (ie. Outlook, Eudora or Thunderbird) isn't configured properly. We suggest the following:

Please ensure that the SMTP port number is set to 25 and that the option "My outgoing server (SMTP) requires authentication" is selected.

IMPORTANT
Also ensure that you are using your full email address as your username. There were recent security changes made over the last couple of weeks to ensure no unauthorized email access is used.
