REDUCTION OF UNNECESSARY MESSAGE AND MESSAGE WHICH IS NOT REQUESTED BY RECEIVER TO BE TRANSMITTED

摘要

PROBLEM TO BE SOLVED: To enable the generation of an input for more reliably classifying electronic messages, for example, as unnecessary messages and/or messages which are not requested by a receiver to be transmitted, by supplying the electronic messages to a message classifying module. SOLUTION: In one embodiment, a transmission server supplies a suitable response to address confirmation data, thereby indicating that there is a low possibility that the transmission message server may use a falsified network address. In another embodiment, it is determined whether or not the message server is permitted to transmit an electronic message due to a certain domain. COPYRIGHT: (C)2005,JPO&NCIPI
