This is working well.  I have another related question.

For my test user I found the Preferences for Folder Display had a
check for  "use IMAP folder subscriptions".  I don't remember if I had
set that, but the default might have been this is checked.  Is there a
way to make it unchecked for all users so that the other settings are
causing all subfolders to display?
