>From man 5 postconf: | mydomain (default: see postconf -d output) | The internet domain name of this mail system. The default is | to use $myhostname minus the first component, or "localdomain" | (Postfix 2.3 and later). together with | myhostname (default: see postconf -d output) | The internet hostname of this mail system. The default is to | use the fully-qualified domain name (FQDN) from gethostname(), | or to use the non-FQDN result from gethostname() and append | ".$mydomain". seems to explain the default value of $myhostname in your case quite well. -- Regards mks
