Hello Timo,
if i use "hidden = no" at the private namespace, the complete namespace isn't viewable,
"complete" meaning what? Some do show? I don't see any folder in the private namespace. I see only the folder of public namespace. I tried this configuration once more and the same happend.
if i use "hidden = yes" i see the prefix "private" at
the foldernames in my emailclient. you haven't configured "private" prefix anywhere, so they're probably i the mailbox narivate."... mes themselves..? no. if i didn't configure the option "hidden" i saw all normal. I couldn't verify this effect this evening :-(
if use / as the seperator like dokumented at the wiki it doesn't work.
Why? Probably a client problem.
Now it works... don't ask me why :-(
Well, Dovecot doesn't currently really support these kind of shared mailboxes, but you might be able to kludge it:
With ACL plugin you can create dovecot-acls file to the maildirs that you want to share to others. http://wiki.dovecot.org/ACL
I will see it. I hope this kind of ACLs work with virtual users. For my kind of LDAP stored ACLs i can use a python script to generate the files.
