Mailbox name not allowed. The server response was: sorry, your mail was administratively denied. (#5.7.1)

This Error is site wide and it is not the host it is in the script. If no one has any suggestion on where to look or how to fix I will have to remove the components that do not work. Don't have the 1500-6000 dollars a year for tech support please if anyone has or knows how to fix the script in this error please let me know. I am trying to build this site on my own and have a very low budget at the moment. But I think that is a nation wide thing.

Come to find out it was the host were the problem was. It just took more than one attempt contacting support to resolve the issue. But here is the resolution to the problem you need to create an email forward in godaddy to work. below you will find out how it is done.

Dear Sal,

Thank you for contacting online support.

This error most often occurs when you are attempt to send mail from an address that is disallowed. Please note that because your site is attempting to use our mail servers, you will not be able to use a 3rd party email address, such as the Comcast.net address which you have mentioned. You will need to use an email associated with one of your domains as the sending address (Ex. webmaster@mydomain.com). If you wish for responses to this address to be directed to your Comcast account, you can setup an Email Forwarding address to accomplish this. We thank you for your understanding in this matter.

To setup an email forwarding account, please use the following instructions:

1. Select 'Email/Email Forwarding' option from the 'My Products' menu (If this option is not available you will need to select 'Free Products List').
2. Click on the 'Email Forwarding Accounts' link.
3. Click on the 'Use Credit' link if you are using a free credit, or the "Manage Account" link otherwise.
4. If using a credit, Make the domain choice on the right hand side, and click the "Continue" button.
5. If using a credit, Now you can click the "Manage Account" link next to the email account.
6. Click the orange "Add" button to the right, next to the email account to setup.
7. Enter the first part of the email address that you are planning to create.
8. Choose the domain you wish to use from the dropdown list.
9. Enter the email address you would like all mail forwarded to in the 'Redirect Mail To' field.*
10 Select 'Yes' if you would like this account to be a catch-all account.
11. Select 'Yes' if you would like this account to have an auto-responder.
12. Click 'Save Settings' at the bottom.

*All messages sent to this address will then be forwarded on to the address you specify automatically.
