Postfix-Konfiguration: Do not list in BOTH mydestination and virtual_alias_domains

[Bastian Pfleging]

Hallo zusammen,

auf einem meiner (virtuellen) Server läuft ein Ubuntu (12.04) mit Plesk 
(12.5) und Postfix (2.9.8) und eigentlich läuft soweit alles ganz gut.
Der Server ist unter server.example.com (anonymisiert!) zu erreichen und 
für verschiedene mit Plesk verwaltete Domains zuständig, inklusive 
example.com.

Was mich verwundert, ist, dass ab und zu die folgende Nachricht im 
Logfile auftaucht:
Dec 23 02:32:44 server postfix/trivial-rewrite[14032]: warning: do not 
list domain server.example.com in BOTH mydestination and 
virtual_alias_domains

Die Meldung taucht scheinbar nur auf, wenn "MAIL FROM: <>" verwendet wird...

Was sollte ich tun, um die Warnung zu beseitigen? Was mich stutzig 
macht, ist die Tatsache, dass postconf eigentlich nur folgende Werte für 
mydestination ausspuckt: mydestination = localhost.$mydomain, 
localhost.localdomain, localhost
mydomain = example.com



Im näheren Umfeld des besagten Fehlers gibt es folgende Einträge 
(<ipaddr> ist die Adresse des einliefernden Clients, die Mail ging an 
eine Mailadresse einer weiteren Domain, die lokal verwaltet wird):
Dec 23 02:32:43 server postfix/smtpd[14022]: connect from unknown[<ipaddr>]
