Change mail server name
A mail server publishes its 'name' in several ways:
* when sending a HELO or EHLO command to a remote mail server, it will say something like _EHLO mail.server.name_
* when an SMTP client connects to it, it will say something like _220 mail.server.name SMTP server ready_
The mail server name should, ideally, be the DNS name of the mail server because some other mail servers will check this.
