Well, that's normal when you enable ACL plugin, because for public
namespace the default ACLs is "no permissions".

No, all dovecot-acl* files are supposed to exist in maildir itself
(because some people want to use per-user control dirs).

When there's no dovecot-acl-list file (in /data/mail/logs), it's
supposed to build it by reading all dovecot-acl files.

You could also try out stuff by not LISTing mailboxes, but rather trying
to manually SELECT one of the mailboxes that's supposed to exist. When
you get that working, LIST is the next thing..
