Hi Victor, I managed to resolve the issue. The mailbox was corrupt but Cyrus reconstruct did not really reconstruct anything until I deleted the cyrus.cache/index and header files from the mailbox.
Everything came up fine after that. There was no doubt that Cyrus had an internal error. After most of the day with no good clues I was at a loss as to what the root cause might be. Having someone give me some certainty that postfix was likely not involved helped so thanks again.
