The "mail name" is the domain name used to "qualify" _ALL_ mail           │
 │ addresses without a domain name. This includes mail to and from <root>:   │
 │ please do not make your machine send out mail from root@example.org       │
 │ unless root@example.org has told you to.                                  │
 │                                                                           │
 │ This name will also be used by other programs. It should be the single,   │
 │ fully qualified domain name (FQDN).                                       │
 │                                                                           │
 │ Thus, if a mail address on the local host is foo@example.org, the         │
 │ correct value for this option would be example.org.                       │
 │                                                                           │
 │ System mail name:                                                         │
 │                                                                           │
