INFORMATION COMMUNICATION SYSTEM

摘要

PROBLEM TO BE SOLVED: To solve the problem that communication function information of only an adjacent information communication device can be known in a conventional information communication system. SOLUTION: An SMTP (Simple Mail Transfer Protocol) server is provided with a processing function (S201-S209) of transmitting a request command for acquiring function information to an adjacent SMTP server via a network to acquire expansion function information of other servers obtained by the server, and correlating the acquired expansion function information with a domain name corresponding to this to store it; and a processing function of notifying the communication function information which is previously stored in response to the acquisition request from the adjacent server via the network.
