OK - then if I copy the files/folders over to another server running
uw-imapd, the flags are in the message headers of each email in each
mbox file so I don't need to copy anything other than the mail itself
and a similar version of uw-imap should be able to serve the status
flags via imapsync which is what I was worried about.
