Unfortunately, all the clients know the IP address of the old server,
so the frontend has to run there.  Of course, the old IMAP server has
to run there too.  Is there not a way to have the old IMAP server listen
on different ports, so that only the frontend connects to it?  If not,
could it listen on a secondary IP address only?
