We send the Quick Check view by default. This removes spam caught by our most accurate spam filters (that have false positives of less than 1 in 2,000.) This means you don't have to go over messages that are almost definitely spam, and you can focus your attention on a shorter list that has a higher likelihood of containing real mail.
If you want to make sure that you review every message we hold for you, you can switch to the "Held" view. If you use the Aggressive settings, and you only want to review messages held by the most aggressive filters, you can use the "For Review" view.
We do not recommend using the Bounced or All Messages views for emailed reports.
