The columns that are shown by default are "Sender", "Subject", "Recipient", "Date" and "Size". There are also columns for "File Name", "Rule Type", "Rule Value", "Rule Source", and "Domain", but they are hidden by default. To change which columns are visible, use the "Message View Columns" menu item under the "View" menu.

Alternatively, you can control+click on the column header to get a popup that will allow you to choose which columns to show.
