mx name server

Users are using mx server like yandex, google.
When adding dns server, .domainname is added.
this can be done by hand.

Hello !

I am not quite sure about your question, can you please give some more details?

Thank you.

some domains use google, yandex mail. mx records are not added.
they can be done manually.

How do you want it to be? You can use Add/Delete DNS records to add MX records.
