I think I heard that Thunderbird uses IMAP ACL extension to check if
some mailbox is shared or not. Dovecot doesn't support IMAP ACL
extension yet. Or it might be something else too I suppose.

Well, unfortunately that doesn't work. Dovecot doesn't currently support
subscribing to namespace prefixes, only to mailboxes inside the
namespace. You might be able to kludge around that by making the
subscription go to the private namespace. Either manually updating the
subscriptions file, or removing this code from
src/imap/cmd-subscriptions.c:

	if (!client_verify_mailbox_name(cmd, verify_name, subscribe, FALSE))
		return TRUE;

Actually another problem you're going to have is those shared namespace
subscriptions, unless you want to force every user to have same ones. If
you don't, you'll need to set CONTROL path to user-specific directory.

For Dovecot v1.1 I'll try to figure out how to make all this work
better.
