             sage that contains an address that includes an invalid zero-length
             O/R address attribute.

             Encoded Information Types.

          o  The Gateway correctly translates the posted date on messages from
             Message Router systems where network time is offset from GMT.

          o  The Gateway uses the MAILbus 400 subject field to create a Message
             Router subject field when it receives a message that contains
             ALL-IN-1[TM] or DIGITAL[TM] Office Server P1 extensions.
