Last night we migrated from Courier-IMAP to Dovecot 1.2RC5 and all
seems to work fairly well, but I seem to have lost all my mailboxes
apart from INBOX. The maildirs are all on the HD in the correct place
(/usr/local/virtual/bordo.com.au/jlbrown):

Any idea how to get them back?

Same with my Sent emails - only the emails sent since switching to
Dovecot are there.

Thanks,

James.
