Adds "Follow Up" items to the Message and contextual menus (and optionally a toolbar button) of Apple's Mail application that allows you to compose (and then send) a quoted version of the original message to all of the original recipients, keeping the To, Cc and Bcc addresses exactly as they appeared in the original message. Specifically, in keeping with Mail's built-in Reply and Reply All functionality, the plugin adds "Follow Up" (original To: recipients only) and "Follow Up All" (all original recipients) functionality via both menus and toolbar items.
