HN is not really a good place to troubleshoot such things but I will take a look.

I do not see an MX record in public DNS for tkangz.sa assuming that is the domain in question. I do not even see NS records for that domain in the root servers. Your DNS admin needs to verify they updated the name server configuration for the root DNS servers. Usually this is in a web interface option called something like "manage your DNS servers" in the new registrar. This can take some time to propagate depending on the back-end of the old and new registrars. If unsure call the new registrar and describe the problem.

    dig +short NS sa | head -n1
    s2.dns.sa.
    
    dig @s2.dns.sa. NS tkangz.sa | grep status
    ;; ->>HEADER<<- opcode: QUERY, status: NXDOMAIN
Status should be "NOERROR" and list the names and IP addresses of your new name servers. After that is resolved then ensure the PTR record at the new location as been updated to match the forward mail server name.

Thank you Bender for answering and for the hints. What are those two dig commands are for?

This is some additional input about Our mail service is hosted by Google. The challenge we are facing is how to make Google recognize and accept external email coming from outside of Google and also deliver messages from our domain to non Google based addresses.
