Hmm... I'm weak on POP, but I suspect you're out of luck unless you
move your clients to IMAP. It will involve an initial download of
messages, but once that's done, you should be able to clone between
dovecot instances without the clients noticing.
But I think you're coming from another POP server? I don't have the
original email any more.
