E-MAIL SYSTEM

摘要

A notice to the effect that an e-mail sent from a communication terminal of the e-mail sender has been opened at a communication terminal of the e-mail recipient is sent to the communication terminal of the e-mail sender without sending an e-mail as the replay from the communication terminal of the e-mail recipient. When an e-mail received from a portable wireless telephone terminal (11) is an e-mail with an open confirmation flag ("Yes" at step S31), an e-mail managing device (14) sends to a portable wireless telephone terminal (13) an e-mail arrival notice (M1) of the e-mail with the open confirmation flag for notifying that an e-mail such that when the e-mail is opened, this fact is reported to the sender has arrived (step S33). When the potable wireless telephone terminal (13) sends an acceptance notice (M2) to the e-mail managing device (14) as the reply (step S24), the e-mail managing device (14) sends the relevant e-mail to the portable wireless telephone terminal (13) (step S34) and sends an e-mail open notice (M3) to the portable wireless telephone terminal (11) upon sending the relevant e-mail to the portable wireless telephone terminal (13) (step S35).
