Electronic mail system for transmitting information via communication network
First Claim
1. In an electronic mail system in which electronic mail information, transmitted from terminals connected to a communication network with designations designated, is delivered to designated terminals, comprising:
- a mail center including an electronic processing device,said electronic processing device comprising;
storage means for storing wrong destinations of mail information;
entry means for entering a designated destination in said storage means as a wrong destination when a line is connected between said electronic mail processing device and a terminal designated by an originating terminal as a destination of electronic mail information and said designated terminal makes a response that the destination is in error; and
delivery control means for deciding whether or not a destination of said electronic mail information designated by said originating terminal has been entered into said storage means each time electronic mail information is received from said originating terminal, performing a process of delivering the received electronic mail information to the terminal designated by said originating terminal when the designate destination is not entered in said storage means and performing no process of delivering the received electronic mail information to said designated terminal when the designated destination is entered in said storage means;
said delivery control means including means for informing said originating terminal that the destination is in error when the destination designated by said originating terminal is found in said storage means; and
a mail adapter connected between a terminal and said communication network and comprising;
terminal interfacing means for communicating signals with said terminal;
network interfacing means for communicating signals with said communication network;
storage means for storing destination information of a plurality of terminals registered as broadcast destinations assigned to broadcast groups;
destination output means for receiving an inputted destination information inputted when a user of a terminal inputs a functional code specifying a broadcast and destination information specifying at least one terminal in broadcast destinations and comparing said inputted destination information with the destination information in each of said groups stored in said storage means and for outputting as the destination of the broadcast the destination information for the group having a coincident result in said comparison; and
mail adapter converting means for converting information output from said destination output means to prescribed signals depending on said communication network and sending converted signals to said communication network via said network interfacing means.

Abstract
An electronic mail processing device includes a magnetic disk with a control table. The device establishes a line between an originating terminal and a destination terminal designated by the originating terminal as a destination of electronic mail information and enters the destination into the control table provided on the magnetic disk as a wrong destination when the destination terminal performs no prescribed response operation to receive the electronic mail information. No electronic mail information is delivered to any of destinations entered into the control table. Thereby, once a destination is stored in the control table, a line is never connected to the destination terminal again, which prevents repeated wrong calls from being made to the same terminal.

2. In an electronic mail system comprising a mail center and in which electronic mail information, transmitted from terminals connected to a communication network with destinations designated, is received and delivered to designated terminals, an electronic processing device of the mail center comprising:
-
storage means for storing wrong destinations; entry means for entering a designated destination in said storage means as a wrong destination when a line is connected between an originating terminal and a terminal designated by said originating terminal as the destination of electronic mail information and said designated terminal performs no prescribed response operation to receive said electronic mail information after recognizing a call; and delivery control means for deciding whether or not a destination of said mail information designated by said originating terminal has been entered into said storage means each time electronic mail information is received from the originating terminal, performing a process of delivering the received electronic mail information to the terminal designated by said originating terminal when the designated destination is not found in said storage means and performing no process of delivering the received electronic mail information to said designated terminal when the designated destination is found in said storage;
said delivery control means including means for informing said originating terminal that the destination is in error when the destination designated by said original terminal is found in said storage means. - View Dependent Claims (3, 4, 5, 6)
