If you use the skiplist backend for seen state, you'll have a *very* 
hard time creating this outside of the protocol.  You *could* create it 
using the flat file backend and then convert it, but I wouldn't 
recommend this either.

What I would do it use the mailtuil utility from the UW IMAP server 
distro to migrate the messages.  This utility will copy the messages 
from your mbox format to Cyrus and set the \Seen flag accordingly.  It 
might also do subscriptions, but I don't know.
