My “mail” subdomain is in use by my postfix relay (which I do not want on mxroute). Is it possible to use a separate subdomain without breaking anything on your end? e.g. awesomemail.domain.com ?
I tried editing zones on cpanel to add awesomemail, and got this error:
Error: Your hosting provider must enable the “Zone Editor (AAAA, CAA, SRV, TXT)” feature to add or modify cPanel-generated records. Currently, only the “Zone Editor (A, CNAME)” feature is enabled for your account.
