Spezielles Problem,

bitte log-Files sowie .conf Files posten.

Gruß

Hallo!

Es geligt mir, eine sasl2 Datenbank mit Benutzern zu erstellen, die sich über
CRAM-MD5 einloggen können. Allerdings muss ich dann jeden Benutzer einzel eintragen. Es sollten aber jene Benutzer verwendet werden, die auch über POP3 Zugriff haben.

Habe LogLevel auf 15 gestellt, dann folgende Ergebnisse:
