[Postfixbuch-users] Mein Mailserver kennt mich nicht mehr

[Ralf Petry]

Guten Morgen,
ich habe privat einen Mac Mini Server im Einsatz, der auch weitestgehend 
zu meiner Zufriedenheit läuft / lief. Unter anderem werkelt eine 
Kombination aus Postfix und Dovecot. Mails hole ich von meinen 
verschiedenen Postfächern vermittels fetchmail ab.
Nach dem Update auf Yosemite musste ich die Server App erneuern (von 
Version 3.2.2 auf 4). Seitdem kann fetchmail die Mails nicht mehr 
loswerden. Die Fehlermeldung lautet:
---
fetchmail: SMTP error: 550 5.1.1 <ralf at localhost>: Recipient address 
rejected: User unknown in local recipient table
---
Ich verstehe zwar, was mir die Fehlermeldung sagen will, aber ich 
verstehe nicht, warum und vor allem nicht, wie ich dem Fehler abhelfe. 
local_recipient_maps (in main.cf) steht auf:
---
proxy:unix:passwd.byname $alias_maps
---
wobei dieser Eintrag nur bei einem postconf -d erscheint. In postconf -n 
taucht der Parameter nicht auf.

Nachfolgend noch postconf -n (ah, btw. gibt es einige Warnings bezügl. 
ungenutzter Parameter. Kann ich die dann einfach auskommentieren?)
