Postfix Configuration
---------------------
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: sgv-nicosc-04.ethz.ch
