[Dovecot] Managing public folder ACL files

Similar to Jan Phillip, we have a small setup where we give permissions 
to groups and then I can add or remove users from the groups fairly easily.

So on all your sales folders, you have a few groups:

Your user X, you would maybe put in the "everything-full-access" group.
User Y would get added to the "sales-full-access" group.

This part gets a little trickier, but you could still do it with groups.

Again, we have a small setup -- nothing so large as yours... so even my 
suggestions may not be the best for you.
