[Postfixbuch-users] mail for ... loops back to myself

[ronny at seffner.de]

Hallo Gruppe,

wenn ich bei meinem postfix Server mail an eine unbekannte (nicht 
registriert) Domain abgebe, erhalte ich in Betreff erwähnte Meldung. Ich
habe 
vom Server aus geprüft, dass er tatsächlich keinen MX für die Domain findet,

anbei die Ausgabe von postconf -n:

Hier die mysql-virtual_mailbox_domains.cf:

user = syscp
password = ********
dbname = syscp
table = panel_domains
select_field = domain
where_field = domain
additional_conditions = and isemaildomain = '1'
hosts = localhost


Ich habe ferner geprüft, dass in der SQL Tabelle die unbekannte Domain nicht

auftaucht. Postfix sollte also gar nicht auf die Idee kommen zuständig zu 
sein. Kann mir das einer erklären?
