One of my clients has a GoDaddy account and after many hours ****ing about trying to get the emails to send, I kept getting the error " (reason: 553 sorry, your mail was administratively denied. (#5.7.1)) "

As recommended on many of the support threads, I tried entering one of the 'real' email addresses that was set up and zilch.

The solution? I simply entered [email protected] as the 'from' email address in email settings and it all started workin just fine with the default settings.

It's not a perfect solution by any means, but at least now the confirmation order emails and welcome emails are going out.

I have to say GoDaddy are less than helpful in trying to get any support out of them, hopefully this will help others to get their GoDaddy hosted Zen Cart emails to work (though I would highly recommended you to look for another hosting plan )

I'll report back here if for any reason it stops working, but so far all well and good
