Here are instructions from Anne Roberson on how to close the preview pane in Mail.
Disabling the preview pane. Put Mail into classic view by opening Mail preferences (Cmd-Comma) and selecting Viewing in the toolbar then checking the Use classic layout check box. Close Mail preferences and navigate to the messages table. Do not interact with the messages table but press VO-Down Arrow. You should be on a horizontal splitter. Make sure the Trackpad commander and Quick Nav are off. Bring the mouse (VO-Cmd-F5). Press down on the bottom edge of the trackpad with one finger, and use another finger to stroke the trackpad toward you. There should be nothing below the horizontal splitter the next time you press VO-Down Arrow. Sometimes it takes several attempts to get it right. >From now on, you should be able to read messages by pressing Return.
