And a bit more generic statement about anything related to errors in Dovecot: Problems that admins can solve are temporary errors for users and the'll need an error logged. Problems that are caused by users themselves (like over quota) are usually not temporary errors and they shouldn't have errors logged (since admin can't usually do anything about them anyway).
