Just curious what the significance/consequences of doing this (deactivating mail service) would be on any sub-domains I have setup?
Meaning, I have my domain, mydomain.com, which shows these services – DNS Domain Name, Domain Registration, Web, Mail. Say I also have this.mydomain.com and that.mydomain.com setup, and the Web Admin Panel shows that Web and Mail are active on each.
If I only want to receive mail at the main domain (email@example.com), and never at the subdomains (firstname.lastname@example.org), does it matter if Mail is active or not? Does Mail service have to be active if I have, for example, a PHP script on that subdomain that sends an email?
