dovecot-2.2.28-1.el6_31.wing.x86_64

I've created this public shared namespace with

namespace public2 { type = public separator = . prefix = Public2. location = maildir:/mail/public2:INDEX=/mail/%u/public:LAYOUT=fs:DIRNAME=.store subscriptions = no }

and I'm using the "imap_client_workarounds = tb-extra-mailbox-sep"

and filesystem structure listed at the end.

The problem is that with this configuration thunderbird (and roundcubemail) shows the Public2 namespace but empty - without any folders. I've tried with another DIRNAME=StoR - same effect

If I will not use DIRNAME at all(and no .stor directories) TB sees the f1 f2 folders but not the f2/s1 subfolder. Just like it would not list any subfolders for subscription.

Within TB I can create subfolder say f1/mysub1 but after it's unsubscribed cannot be subscribed again(not shown in listing)

Can You provide any hints? I can live without the DIRNAME= but it has to list subfolders for subscription.

BTW: it works well without LAYOUT=fs - but it's kind of requirement here.
