So you have Maildir++ layout and you don't have listescape plugin? And you have namespace separator set to '/'? In such setup having '.' just isn't valid. All '.' characters in the directory name get converted to '/'. If on filesystem you have .GVV-tangy.GVV/, that shows up to client as "GVV-tangy/GVV". There should be no '.' anywhere. You could enable rawlog to see what the clients are trying to do. http://wiki2.dovecot.org/Debugging/Rawlog
