[Dovecot] No status for INBOX/* in mbox NS (2.1.6)

[Jost Krieger]

Maybe it's fixed, but the last "interesting" text in the Changelog was
before 2.1.6.

Most of our users still have mboxes in the classical layout, so you
can't have subfolders and messages in the same folder, *except for the
INBOX*, as it is physically separate.

Someone complained that he saw subfolders in roundcube he couldn't
delete, because they didn't show up in the subscription view.

Before hitting on roundcube, I mperformed a few checks and got the
following:

root at cx-y-z qmail # doveadm mailbox status -u usera messages 'INBOX/*'
root at cx-y-z qmail # doveadm mailbox status -u usera messages 'INBOX/test1'
INBOX/test1 messages=0

This is mysterious.

It doesn't happen with my account, that is in a mdbox:
root at cx-y-z qmail # doveadm mailbox status -u kriegjcb messages 'INBOX/*'
INBOX/test1 messages=1

Our setup is a bit complicated, but most of it shouldn't be relevant to
the problem.
