10.8.3 broke my Mail.app

[throttlemeister]

After installing 10.8.3, Mail stops automatically retrieving new mail for all accounts. Both IMAP IDLE and 'check for new messages every..' setting appear to be completely ignored and the only way to retrieve new mail is either when the computer wakes from sleep, or to manually hit the get new messages button.

Am I the only one with this problem? Any suggestions on how to solve this? This is just too annoying.

Fixed it.

Had to remove com.apple.mail.plist from ~/Library/Containers/com.apple.mail/Data/Library/Preferences

The same plist in ~/Library/Preferences is a legacy dummy that is no longer being used.
