No, they're the unique identifier numbers for each message.  I believe the
problem John was asking about is, what happens if you have, say, an APPEND
happen to a mailbox on both servers while they are not in communication
with eachother.

When they resync, each has a new message with the same unique identifier,
but different contents.  This isn't a situation that can be recoverd from
just be looking at the contents of the filesystem.

Doing replicated IMAP stores (espeically geographicly distanct ones) is
not an easy problem.
