IMAP, INBOX is in mbox format.  

I've had no reports or evidence of this happening anywhere other than 
INBOX.

The messages headers are being retrieved more than once, and the client is 
showing them as new mail.  I don't know where all the new/read/deleted 
flags are kept.  I suspect some of them are in IMAP, and some in the 
clients.

I was sufficiently surprised by this to mail the list, as dovecot has been 
very stable for us.  I downgraded this server to 1.0rc17, and I have not 
seen the problem recur.
