MAIL DISTRIBUTION SYSTEM, MAIL DISTRIBUTION METHOD, AND MAIL DISTRIBUTION PROGRAM

摘要

When an alias mail relay server (10) receives an alias mail destined to an alias address X (R, C) from a transmitter terminal (1), it restores a receiver address R and an alias address generation argument C, generates a reply destination address Y (S, C) containing the restored generation argument C and the transmitter address S, replaces the destination and the transmission source with the receiver address R and Y(S, C), and transfers it to the receiver terminal (2). On the other hand, when a re-mailer (20) receives a response mail from the receiver terminal (2), it restores the transmitter address S and the generation argument C from Y (S, C), re-generates X (R, C) from the restored generation argument C and the receiver address R, replaces the destination and the transmission source address S with X (R, C), and transfers it to the transmitter terminal (1).
