Email delivery mystery

I’m using the delivery of an email from UI Builder and it’s not working.

All the email under System Events works properly and the customs templates are not working, from the console or fro UI Builder same problem:

This message was created automatically by mail delivery software.
A message that you sent could not be delivered to one or more of its
recipients. This is a permanent error. The following address(es) failed:

Also this same code in the same project is working properly with the same email server.

I was testing different things and same code, same email server with a email address outside my server it’s not working and email with a domain inside the server deliver the email OK.

The solution should be calling the GoDaddy support to check if it’s something there. But it’s not a Backendless problem at all.

Any suggestions ? Thanks, Mario

Hello, @Mario_Ghersi.

Can you please provide your app id?

Regards, Nikita.

App ID = 147F3E51-266A-AAC4-FF2B-DFE9F84FD200

I’m using GoDaddy. The delivery is OK if the domain is the same of my domain, my problem is with the cPanel configuration in Automatic, I have the error. At remote no error and no send it.

Any suggestions how to set up or what email server can I use with Backendless?
Thanks, Mario
