Sehr geehrte Damen und Herren,

dank der tollen Unterstützung durch das Forum konnte ich mailcow erfolgreich einrichten und bisher auch problemlos betreiben.

Vor ein paar Tagen habe ich versucht, einen Sync-Job zu erstellen, der lief sich aber “Tod”.

Daraufhin lud ich die Seite neu, und alles wirkte normal, lediglich der Sync-Job war nicht erstellt worden.

Seitdem kann ich mich, wie bereits im Titel der Frage erwähnt, zwar problemlos in SOGo einloggen, aber nicht mehr mit Thunderbird.

Also habe ich die Logs durchgelesen und dovecot gab diverse Fehler aus.

Daraufhin habe ich mailcow mit docker compose down / docker compose up -d neu gestartet, was leider keine Abhilfe bewirkte.
Also habe ich den Hetzner-Server, auf dem ich mailcow betreibe, mit zwei zeitlich unterschiedlichen Backups neu aufbauen lassen.

In beiden dürfte der Fehler nicht definitiv nicht vorhanden sein, dennoch bleibt er weiterhin bestehen.

Die Dovecot Logs enthalten weiterhin Fehlermeldungen, die anderen Logs sehen, soweit ich das beurteilen kann, gut aus.

Dovecot Log:
