ACL - Unterordner und andere Ordner als INBOX sharen

[Martin Bock]

Hallo allerseits,

ich komme mit meiner Konfiguration von Shared Foldern nicht weiter. Es
ist zwar möglich, die INBOX zu sharen, das wird beim Gegenüber auch
korrekt angezeigt. Unterordner oder andere Ordner als die INBOX bekomme
ich aber nicht geshared.
Was mich verwirrt ist die Debug-Meldung, er könne in mail/.INBOX.Server/
keine dovecot-acl finden - wieso sucht er überhaupt nach einem Pfad mit
Punkten (als falschen Separator?)?

Vielleicht kann mir hier jemand weiterhelfen, denn ich stehe komplett
auf dem Schlauch...

Danke und viele Grüße
Martin Bock

Bei der Anmeldung vom Gegenüber gibt mail_debug Folgendes aus:
> Debug: Namespace : type=shared, prefix=shared/%u/, sep=/, inbox=no,

In martin.bock at bock.online/INBOX/Server/dovecot-acl steht aber:

In dovecot-acl-list:
