You don't have any Thunderbird clients accessing this box do you? Yes, I have. But I also experienced the problem myself only using mutt and Apple Mail.
I have some w[ei]rd issue where our TB with the option "don't mark message read", still triggers messages to be marked read It's the other way round. People read their messages, they are flagged as read and all of a sudden revert to unread.
