Changed .Inbox to .INBOX now there is only one folder named INBOX 
visible. The ACL's from /home/vmail/%u/mail are used for all subfolders 
under ../mail no matter if they have an dovecot-acl file inside or not. 
Can not find this documented, it's useful in my case but is it supposed 
to work like that? Nice thing is i can create root-level folders for 
users with an mail_location configured like that in the shared subsections.
