You will be prompted for the 'proxy_user' password.  You can hardcode the
password with a small change in mailutil.c.  Let me know if you need help
with this...

I do not think you have enough time to transfer several gigs (if not more)
of email in just a few hours over IMAP protocol.  You can speed things up
if you run multiple mailutil's at the same time, you can also disable
duplicate suppresion while you run the conversion.  Otherwise, I would
allow imap/pop/lmtp connections and run the conversion.  Some folks will
not see their old email until the conversion completes.
