1. A system for transmitting originated information from one of a plurality of originating processors in an electronic mail system to at least one of a plurality of destination processors in an electronic mail system comprising:

  • at least one gateway switch, the at least one gateway switch storing originated information received from one of the plurality of originating processors prior to transmission of the originated information to the at least one of the plurality of the destination processors;

    a RF information transmission network for transmitting the originated information to at least one RF receiver which transfers the originated information to the at least one of the plurality of destination processors;

    at least one interface switch, the at least one interface switch being coupled to at least one gateway switch and to the RF information transmission network and transmitting the originated information received from the at least one gateway switch to the RF information transmission network; and

    at least one additional processor with each additional processor being coupled to at least one interface switch, one of the at least one additional processor originating other originated information from outside any electronic mail system for transmission to the at least one of the plurality of destination processors by the RF information transmission network and an address of the at least one of the plurality of destination processors to receive the other originated information transmitted by the RF information transmission network or an identification number of the at least one RF receiver receiving the other originated information for transmission to the at least one of the plurality of the destination processors and transferring the other originated information to the at least one of the plurality of the destination processors; and

    whereinthe interface switch receiving the other originated information originating from the one additional processor and the address or identification number adds RF network information used by the RF information transmission network during transmission of the other originated information to the at least one RF receiver receiving the other originated information to the other originated information; and

    each electronic mail system in the system transmits other information from one of its plurality of originating processors through a wireline to at least one of its plurality of destination processors without transmission using the RF information transmission network.
