HI I have two domains ( Domain A & Domain B ) hosted over GoDaddy cPanel . The issue is , both domain's e-mail services are working fine , both domains are able to send and receive emails from gmail, hotmail etc. But Domain A is not able to receive any emails from Domain B, although it's receiving emails from Domain B.
I have checked Domain B cpanel's track DNS of Domain A Mx record, it's resolving correctly, but issue remains same.
Welcome to the community! That's a pretty odd situation indeed. I think your best bet would be to reach out to our support team to have them troubleshoot this with you. They should be able to do some testing and find the problem.
