Hi everybody,

I have a problem that I cannot share subfolders of the mailboxes INBOX , e.g. /Sent / Trash etc. but also no self created folders. The ACLs seem to be set right. I have the suspicion that the dictionary ( /var/lib/dovecot/db/shared-mailboxes.db ) is not updated - there are no entries for the sub folders

I just cannot find the problem within my configuration. Many thanks for having a look at it.

Cheers from Hamburg, Germany, Christian
