Listing expunged messages

Hello,

Following on my last question about broken mdboxes, removing 

dovecot.map.log and force-resync does work. My last problem now however is that after doing this, messages which were 'deleted' previously, come back in the inbox as new messages.

I have the original mailboxes and can subscribe to the expunged folders and everything in EXPUNGED/INBOX on the original, is appearing in INBOX on this migrated system. I would want to return everything to EXPUNDED/INBOX so my users don't see old dead resurrected messages. Is there a procedure to identify these?

Thanks.

Mike-
