during my tests I've copied and deleted some mails, copied whole
mdbox-files etc. and after some time the IMAP session was dropped by
Dovecot. In the logfile I've found this:

Jul 18 17:36:18 tux dovecot: imap(testuser at dlutt.de): Error: Corrupted transaction log file /home/vmail/dlutt.de/testuser/mdbox/mailboxes/Papierkorb/dbox-Mails/dovecot.index.log seq 2: file size shrank (sync_offset=14724)

Jul 18 17:36:18 tux dovecot: imap(testuser at dlutt.de): Disconnected: IMAP session state is inconsistent, please relogin. bytes=119/850

After a relogin all mails were available and readable without manually
fixing the index. Don't know if this always successful but it seems
that Dovecot can rebuild the index without problems.
