[Postfixbuch-users] 450 Recipient address rejected -- Warum findet er die Domain nicht?

[Karsten Horsmann]

Hallo Liste,

ich stell mich gerade etwas dusselig an. Warum wurde die Email abgelehnt?

Weil die Domain YYY.com (unkenntlich gemacht) nicht auflösbar ist/war?!
Bin für jeden Denkanstoss dankbar.
