public namespace quota

All,

sorry, I've to ask again. I'm trying to define quotas for public namespace subfolders:

ns=public/
	- DepartmentA - 50G
	- DepartmentB - 500M
	- DepartmentC - 10G

public/ shouldn't have a limit. public/DepartmentA is independent of B and C.

Is this possible with dovecot?

I've added the following rules

quota = maildir:User quota
quota2 = maildir:Public quota:ns=public/
quota2_rule = *:storage=10M
quota2_rule2 = DepartmentA:storage=+50M

but then only 10M is shown for DepartmentA in Thunderbird. I'm using Maildir++. maildirsize is only created in public/ toplevel, not in public/DepartmentA.

Public-subfolders are owned by vmail system-user. Different virtual users' ACLs are set (and working).

Any help is appreciated!
