[Dovecot] Public namespaces with global ACLs 1.2+

[Thomas Leuxner]

Some log examples. Trying to create a new mailbox "Newsletters.123"  
under Public/ with a prepopulated "Newsletters.123" ACL file. Although  
it reads that file, it does not allow creation of the mailbox. NB: You  
wouldn't have a glass ball to predict the mailbox name.

Created a .DEFAULT file and the user can create a new mailbox under  
Public/:

Shouldn't it be possible to put the .DEFAULT ACL in a path like ../ 
acls/Public/.DEFAULT to only allow some users to create new subdirs  
under the Public/ namespace?
