Abstract

The conventional email method based on a recipient mailbox has a structural weakness, which may cause the spam message problem and the extreme waste of recipient mailbox space, and also require an explicit recipient notification scheme. This paper proposes a new email method based on a sender mailbox and evaluates its performance. Under the new email method, a message is stored at sender mailbox instead of recipient one until an intended recipient reads the message, so that the burden of mailbox management such as removing spam message is now shifted to sender side. And also a sender can confirm whether an intended recipient has read his or her message by simply rummaging his or her sender mailbox. The results of performance evaluation show that 75% of mailbox space and 90% of message traffic are reduced in conditions that the portions of spam message and multicasting message are 90% and 80%, respectively.
