Accessing to mail as another user

[Angel L. Mateo]

	I have this configuration running, except for the ACL. The problem I'm 
having with ACLs is that I have to manually create the ACL for each 
folder userB has and if userB creates a new folder, then it is forbidden 
for userA until I update the ACL.

	How do you solve this?
