Thanks very much Sandy.
Another questions:
1) I have a primary host machinename.domain.com (official host name) and the
DNS entries are:
domain.com
IN MX 10 machinename.domain.com
machinename IN A X.X.X.X
X.X.X.X.in-addr.arpa., type = PTR
host = machinename.domain.com
If I want that the primary host name doesn?t include the machine name (for
example mail.domain.com), What are the entries in the DNS that I must add ?
2) I add a virtual host without IP and the DNS entries are:
domain3.com
IN MX 10 machinename.domain.com (It is the primary host)
When I configure this virtual host, What?s the official host name for it?
What are the entries in the DNS that I must add ?
Regards,
Federico Rissone.

Yes. It is far preferable to use the canonical host name, or another
valid host name that resolves to the host's IP on the public Internet.
Using just the domain name will create DNS issues resulting in your
server being blocked by sensitive anti-spam systems, _unless_ you have
an A record for the zone origin (example.com) pointing to the
mailserver IP (this is generally not the case--rather, example.com is
an expected alias for www.example.com).
You should never use local settings that extend incorrectly into the
public DNS space.
