[Postfixbuch-users] Name service error for name=localhost type=A: Host not found

[Thomas Grieder]

Hallo Liste

Ich habe folgende Fehlermeldung beim Empfangen von Mails:

Host or domain name not found. Name service error for name=localhost type=A:
Host not found

Eigentlich wollte ich die experimental Pakete (debian) von Courier
ausprobieren. Hat auch gut funktioniert bis ich herausgefunden habe, dass
keine Mails mehr ankommen. Inzwischen habe ich alles rückgänging gemacht und
bin wieder stable. Leider habe ich die Fehlermeldung immer noch.

host und nslookup lösen localhost korrekt auf. Ich komme leider nicht mehr
weiter und brauche dringen eure Hilfe.
