Abstract
The electronic mail relay apparatuses relay electronic mails from the transmitting terminal to the receiving terminal. The recipient determines whether a received mail is a junk mail or not. If the mail is a junk mail, the recipient sends a warning notice with respect to the transmitter. If the recipient sends the warning notice a second time, then a penalty invoice notice is issued with respect to that particular transmitter.
