Godaddy says this is a Zen-Cart problem.

E-Mail Transport Method is set to PHP

This has worked before we moved to Godaddy.

"Godaddy says this is a Zen-Cart problem." I would think that this is their copout..
If you know that it functioned somewhere else - How is it a ZenCart issue?

Ask them what in the ZenCart setup is causing this - if they are so sure that it is - they should know why

That looks to be an MTA message which is not controlled by ZenCart

What does MTA stand for?

mail transfer agent - - or specifically the mail server
Try using the developers tool box ans searching for "administratively denied"
You will not find this in the ZenCart files

thanks for the support but I've found one other posting where the same type of error so I'd really like some help understanding just what it is telling me before I go to the mat with godaddy. Can anyone out there help in understanding just what is happening and possible ways to get it fixed.

Interesting, but what does it mean? What domain are they talking about? the one that has my Zen-Cart store?

E-Mail Transport Method is set to PHP
I believe that at NoDaddy you need to set this to SMTP
