1.MAIL> DELETE 2

      This example shows how to remove the second message in a list.

      When you want to remove a message, use the DELETE command.
      You can either enter the DELETE command while you are reading
      the message or you can enter the DELETE command followed by
      the number of the message you want to remove (as shown here).
      The number of the mail message can be found on the directory
      listing.

    2.MAIL> DIRECTORY

      # From             Date                  Subject

      If you enter the DIRECTORY command after you have deleted a
      message (or messages), you will see the messages marked for
      deletion, as shown here.

      When you exit from Mail, the messages marked for deletion are
      deleted if AUTO_PURGE is set. If you set NOAUTO_PURGE or if you
      exit from mail by entering the QUIT command, messages marked
      for deletion remain in the WASTEBASKET folder.
