Snippet #819

On the subject of my Mail.app unread count problems, I notice that a couple files in my ~/Library/Mail folder have values of 9223372036854775807, which happens to be the largest positive number you can represent in a signed 64-bit integer. The values in question are MailboxUnreadCount in mboxes.INBOX in .mboxCache.plist, and IMAPMailboxUnseenCount in IMAP-account@example.com/INBOX.mbox/Info.plist.
