      - clarified behavior on broken connection

      - explicitly permitted an inactivity autologout timer

      - clarified the requirements of the "exclusive-access lock"

        the maildrop

      - allowed servers to close the connection after a failed
        authentication command

      - removed the LAST command

      - fixed typo in example of TOP command

      - clarified that the second argument to the TOP command is non-
        negative

      - added the optional UIDL command
