In the present invention, the an electronic mail transmission terminal device encrypts an electronic mail and transmits the encrypted mail. An electronic mail server device, when the encrypted mail is received, transmits a reception notification mail, which notifies reception of the encrypted mail, to an electronic mail reception terminal device in which a receiver of the encrypted mail is stored. An electronic reception terminal device, when the reception notification mail is received from the electronic mail server device, indicates reception of the encrypted mail to the receiver, requests electronic mail server device to transmit the encrypted mail after performing personal authentication of the receiver. Further, the electronic reception terminal device decrypts the encrypted mail.
