There was another mail with "highest than remote's UIDs" error. Do you mean that one? I don't see others. That's also kind of strange. Dovecot had seen mails that suddenly no longer existed on Cyrus side. It's as if you're syncing to two different Cyrus servers that are somewhat out of sync themselves. Is that possible?
