A very small and fast-loading application which sits in your taskbar until new mail arrives, at which point you can preview the messages and choose to ignore them, delete them or launch your mail program to view them. Requires MAPI to be properly configured (if you have Microsoft Exchange, Windows Messaging or Outlook installed it is)
