[Dovecot-de] Shared- und Public Folder funktionieren nicht richtig

[Ralf Tempel]

Hallo zusammen!
So ganz rund läuft mein Dovecot noch nicht. Probleme verursachen 
Shared- und Public Folder.

Sobald Shared Folder ins Spiel kommen, ist nach dem neu einloggen nur 
noch der Shared folder abonniert, alle Ordnerabonnements außer Inbox, 
Drafts, Sent, Junk und Trash werden vergessen.

Wenn ein User einen Public Folder abonniert, ist er für alle User 
abonniert, wenn ein User diesen Ordner wieder abbestellt, ist er bei 
allen Usern abbestellt.

Hat jemand eine Idee, wo man ansetzen könnte?

Beste Grüße und ein schönes Wochenende.
