Hmh. I can't figure out how that could happen. Also the index files alone probably aren't enough.. Can you send the index files, storage/dovecot.map.index* files and storage/m.* files put through http://dovecot.org/tools/mdbox-obfuscate.pl to remove the actual message contents. Then only the dovecot.index.cache file has anything sensitive (some message headers).
