OK, copy the settings out of what appears in the database.  Fine.  But
how do I set up a Virtual Trash for my user?  If I assign my trash to
be Virtual Trash, after deleting an item I get:

'The folder "Virtual Trash" was not created. This is what the server
said: IMAP error: Permission denied'

What am I missing?  It is something in the backends file for what we
support over IMAP?  I can create regular IMAP folders.  I have
searched "Virtual Folder" in the wiki, and in the config files, etc.
I'm stumped.
