1. A system for the automatic notification of the receipt of a message in an electronic mail system, comprising:

  • a microprocessor connected to receive data items from the electronic mail system identifying queuing messages;

    a random access memory coupled to said microprocessor and organized to form a first file containing;

    identification codes for predetermined addressees of messages,telephone call numbers for said addressees, andsignalling data fixing a duration for the transmission of telephone signalling pulses for each telephone call number; and

    a modem circuit for connection to a telephone line, said modem circuit being arranged and organized to convert the signalling data residing in said first file into analog signals suitable for transmission on the telephone line;

    said microprocessor being organized to read a queuing file of the messages in the electronic mail system in order to detect the presence of identification codes, extract from said first file the telephone number and signalling data corresponding to each detected identification code, and instruct the modem circuit to automatically dial the extracted telephone numbers and transmit telephone signalling pulses via the telephone line for the signalling duration corresponding to each extracted telephone number.
