Wo ist mein Default User hingekommen?

Mi Jul 26 13:57:49 CEST 2023

Hallo Liste,

ich habe ein etwas eigenartiges Problem mit meinem Postfix, wenn ich eine Mail an 
gjn at exemple.com bekomme, wird die Mail nicht angenommen, Server 
mx01.example.com 

Alle anderen domains werden aber angenommen nur die Haupt domain nicht! da wird 
der User nicht gefunden?

z.B. kommen diese Fehlermeldungen

Jul 24 18:27:38 mx01 postfix/smtpd[408091]: NOQUEUE: reject: RCPT from 
pmg.ke71.network[85.10.222.194]: 550 5.1

Auf einem anderen Rechner funktioniert die Konfiguration?

Ich verstehe die Welt nicht mehr ??

die geklonte Konfig als Anhang die wollte ich eigentlich gar nicht nehmen da da noch viel 
altes Zeug drin ist

Danke für jeden Rat und Hilfe,
