Optimal setup for a mail server host : is it better to use mail.domain... or host.domain

[Jintor]

Hi,

I'm setuping a new mail server.

before the cpanel setup I have to setup a hostname... what is better to use mail.domain or host.domain ?

It does not matter, as long as it's a fully qualified domain name and it resolves to your server's main IP.

Personally, I would not use straight up mail. for the domain, though its certainly legal to do so.
