Abstract

An e-mail communication system, in which bothering e-mails can be prevented to transmit to recipients, is provided. In case that a sender (subscriber) connected to an Internet service provider transmitted an e-mail to recipients (subscribers) connected to the Internet service provider, when the e-mail was an unwelcome e-mail (bothering e-mail) to the recipients, each of the recipients transmit a refusal notice to a data server for addresses transmitted refusal e-mails by using e-mails via an e-mail server provided by the Internet service provider. The data server for addresses transmitted refusal e-mails stores the transmitted refusal notices. When the number of the refusal notices per a unit period exceeded a threshold value, the Internet service provider makes the sender stop transmitting e-mails from now on.

Description

technical field [0001] The present invention relates to an electronic mail communication system that performs electronic mail communication, and particularly, a situation in which electronic mail is sent to a recipient regardless of the recipient's intention can be prevented. Background technique [0002] Recently, e-mails are frequently sent and received by using information processing devices such as personal computers (PCs) and mobile communication terminals. However, when the sender knows the email address, the email can be easily sent to the email address. Also, senders can send emails to a large number of email addresses with little communication cost. Through the above-mentioned situation, a large amount of electronic mails are sent to recipients without the recipients' intention to receive them. Thus, a large load is imposed on the e-mail sending server, and an undesirable communication fee is also imposed on the receiver. [0003] To solve this problem, several m...
