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.
