If you are using plain maildir, then I think you could just use rsync to synchronise the two sets of folders and files. I guess you would need to exclude from the rsync operation the dovecot-specific files (indexes and so forth) and allow dovecot to update these itself to reflect the new state of each set of stored messages.
Another option would be to try imapfilter. Olaf
