<p>In electronic mail communications between a remote sending system and a remote receiving system, the remote sending system is allowed to construct a message which will be sent to the remote receiving system and, then, the message is received from the remote sending system with a sender identification of the remote sending system attached as a message header. After the sender identification of the remote sending system is replaced with an identification code specific to the message, thereby itemizing the sender identification and the identification code as a mail database, the message is transmitted to the remote receiving system with the identification code attached as the message header or incorporated into the message itself. <IMAGE></p> |
