This does seem more like a client-issue. At least thunderbird has this issue that you need to fold/unfold folders to see more folders.

Trying to track down a problem I've been dealing with for a while. Everything else works fine - the problem is with shared mailboxes.
My present, and desired, prefix for the shared namespace is: prefix = INBOX/shared/%%d/%%n/
Some mail clients, particularly Thunderbird and Android's AquaMail, have no problem with this. But other (presumably broken) clients don't show the shared mailboxes. This includes EM Client and Webmail Lite. Actually, Webmail Lite lists the mailboxes in the subscription window, but then the "live"folder list shows "shared" and "shared/domain" but none of the shared mailboxes below the domain.
Changing to: prefix = INBOX/shared/%%u/
Works across all clients - but I'd rather have the domain separation. Testing with telnet ". LIST '' '*'" yields the full list with either config.
The files /var/mail/%d/shared-mailboxes contain entries like: shared/shared-boxes/group/allshared/user@domain.com 1
Below is "doveconf -n" output.
