Postfix - LMTP Transport funktioniert nicht

Hallo zusammen,

ich baue mir aktuell einen neuen Mailserver zusammen.
Ziel dabei ist, dass Postfix und Dovecot getrennt auf zwei verschiedenen Maschinen läuft.

Was funktioniert: Mailversand
Was funktioniert nicht: Mailempfang

Der Mail log zeigt:

Was mich dabei wundert ist das hier:
Code: 
connect to subsystem private/lmtp: No such file or directory

Das Setup ist für virtuellen Transport konfiguriert. Die Domain ist in der Datenbank hinterlegt, der Transport lmtp:[dovecot.local]:24 wird auch korrekt von dort geladen.

Was läuft hier schief? Ein telnet dovecot.local 24 von der Postfix-Maschine funktioniert wunderbar. Mail wird auch zugestellt.

Anbei meine Konfig für Postfix.

Vielen Dank, freue mich auf Hilfe :)

Gruß
Marco

Hi,

danke für deine Antwort.
Hatte ich auch schon probiert. Bringt leider den gleichen Fehler.

Meine Erkenntnis ist richtig, dass Postfix lokal nachLMTP sucht, oder?
 
Warum ist in der master.cf lmtp als inet service eingetragen? Änder das mal wieder auf die Defaults zurück.

Code: 
lmtp      unix  -       -       n       -       -       lmtp
 
Hallo,

Danke für die Antwort.
Ja, das war es tatsächlich. Ich dachte, dass ich es dort auch auf inet umstellen muss, da Dovecot auf einem anderen Host läuft.

Viele Grüße
Marco
