I believe that offlineimap inserts an

  X-OfflineIMAP*

header which is what it uses to see if a message is new.  It works
on the principle that messages are immutable, which is part of the
IMAP standard.  But if you remove that header, offlineimap will think
that the message was deleted and that a new message appeared, and
that should do the right thing.
