Our hosting server send's all mail using the dns name cpanel.example.com

All e-mails sent to anyone @example.com are handled thru gsuites however all other mail is recieved and sent from the cpanel server itself aka cpanel.example.com

The problem is if anyone sends an email from cpanel.example.com to any address @example.com the server routes it internally thinking that the mailboxes are locally on the server.

For the life of me I cannot figure out what is going on.

Please help.... Thank You

Hey there! If your email should all be external for the domain you'll just need to tell cPanel this. You can do that from the cPanel >> Email Routing interface. Just choose the domain from the dropdown list and make sure it is set to the "Remote Mail Exchanger" option. Can you try that and let us know if that improves the behavior?
