This is why the /etc/zmailer.conf can have line line:
The problem is at the MX-lookup at the SMTP-client.
The SMTP-client does not know which IP-addresses are
owned by the system, and there is no simple reliable
way to do it... Except by listing them manually.
Above the "mailhost.utu.fi" is a virtual host at "antares.utu.fi",
by means of having separate IP address for itself.
