Then a format rule has to be created for this as some clients might display
the "hidden" message and allow it to be deleted. 

The only minor issue is that now there will be two different ways to
identify he content type of a folder. 

Should we just move completely to the hidden message solution and avoid all
the issue with the annotation database and the fact that it seems that the
annotation extension will not be widely adopted by other IMAP4 servers and
only partially by Cyrus?
