Is it possible to have dovecot enforce the file mode and group owner of
inserted mails without causing flags to be stored privately?  Its looking
like I will have to use a cron job to fix file permissions on mails added
to shared mail folders by imap clients.  I'd be willing to implement a 
local permanent patch but I haven't looked into how easy it would be yet
because I did not (until now) realize that this behavior was intended.
