[Postfixbuch-users] Can't connect to local MySQL

[Thomas]

Hallo,

nachdem ich schon alles nachgeprüft habe, gehen mir die Ideen aus.
Ich habe im Log folgendes stehen:

Jan 24 17:29:22 localhost postfix/cleanup[5390]: warning: connect to 
mysql server localhost: Can't connect to local MySQL
Jan 24 17:29:22 localhost postfix/cleanup[5390]: warning: D098B9BC0FC: 
virtual_alias_maps map lookup problem for root at example.com

smtp und rewrite laufen nicht chrooted.
Mit postmap -q kriege ich die richtigen Ergebnisse, also stimmen die 
Zugangsdaten in den mysql-virtual-Tabellen.
Wo kann ich noch suchen?

Wieso versucht Postfix mit root at example.com zu MySQL connecten anstelle 
von root at localhost?
(Ich weiß, dass der MySQL-root-Account nicht optimal ist, aber wenn es 
nichtmal damit klappt, dann brauch ich auch keinen eingeschränkten 
Account zu versuchen.)

Hier mal die Ausgabe von postconf -n:

Über Denkanstöße freue ich mich.
