Does anyone know how to make two Internet domains pointing to the same mail host?
Like, if I want mails send to, for example, firstname.lastname@example.org
, and these sent mails will all go to abc.com mail host, lets say, mail.abc.com mail host.
Is this all about DNS 123.com zone file config setup? and how do we change the configuration of the zone file?
Is there anything to do with MX?
Or is there anywhere else that we should reconfig?
Please help, Thank you!
