PROBLEM TO BE SOLVED: To send only data which a receiver needs to have in order to reduce the load on a communication path and also to improve the entire operation efficiency of an electronic mail system by sending multimedia data in response to the transmission request given from a mail receiving terminal. SOLUTION: The mail receiving terminal 20 waits for input of a reference request to be given from a user for the multimedia data. When a reference request is received for the prescribed multimedia data, a multimedia data receiving part 23 requests a mail transmitting terminal 10 to send the multimedia data based on the information which is analyzed by an index reading part 22. If a user reject the reference to the multimedia data, these data deleted at the terminal 10. Thus, the multimedia data are directly sent by a user's request with no intervention of a mail service center 30. As a result, the burden of the center 30 can be reduced. |
