Ich verwende MariaDB, um Benutzer für Dovecot 2.2.10 zu speichern. Dovecot gibt immer wieder „Unerwartet getrennt“-Fehler aus und ich kann keinen Grund dafür finden. Gibt es etwas, das ich mir ansehen könnte?

Was bedeutet „unterstützt keine Anmeldeinformationssuche“? Ist das ein Problem mit MariaDB oder Dovecot?

Antwort1
Nun, ich habe diese Frage trotzdem gelöst. Aber es ist eigentlich keine Lösung. Ich aktualisiere einfach mein Dovecot auf die neueste Version (von 2.2.10 auf 2.2.36). Ich weiß nicht, warum das funktioniert (vielleicht wegen irgendeiner übernatürlichen Kraft). Wenn also jemand weiß, warum Dovecot 2.2.10 nicht richtig mit MariaDB funktioniert, antworten Sie bitte unten.
