ELECTRONIC MAIL COMMUNICATION SYSTEM

摘要

An electronic mail communication system or the like capable of transmitting and receiving electronic mail to and from a target who does not have a membership registration without disclosure of a personal electronic mail address and also easy in controlling acceptance or rejection of mail. Where the received electronic mail is determined to be target addressed mail, the decode means 17 of the mail server device 4 writes a target actual address as a field value of a destination header, without changing a text thereof, thereby generating target addressed transfer mail in which a connection address is written as a field value of the source header. Where the received electronic mail is determined to be the user addressed mail, the encode means 14 generates user addressed transfer mail in which the user actual address is written as a field value of the destination header without changing the text.
