I've checked every post I can on this subject and there are plenty.
My web is hosted on godaddy. Works fine. But the email settings are really frustrating.
relay-hosting.secureserver.net is supposedly the smtp server.
Now I read that username should be BLANK but the damn field is green and when I push test send email, I get the message;
Could not connect - Mailbox name not allowed. The server response was: sorry, your mail was administratively denied. (#5.7.1)
And the green username field is filled in with admin or whoever I am when I'm trying to do settings...
Any help would be suggested. There is no trust setting in the web config.
