Description

  The present invention relates to a technology for providing a message communication service such as an electronic mail communicated using an information network, and more particularly to a message communication service providing method, a message communication server, and a message communication program.

  In the following description, an electronic mail (hereinafter referred to as mail) is taken as an example. Conventionally, the mail service has the following problems.

  First, if a service user (simply referred to as a user) has multiple e-mail addresses to use different e-mails according to work or play, he / she accesses an e-mail server (ISP: Internet Services Provider) for each e-mail address. However, it is necessary to check whether mail has been received. However, accessing the mail server for each of a plurality of mail addresses makes the use of the service complicated, inconvenient, and increases the cost of using the mail server.

  In addition, when using the mail forwarding service, you can receive mail without notifying the other party of the real mail address of the user, but the real mail address will be sent when replying. To be known.

  Furthermore, the real mail address may be forced to be changed as a countermeasure against the spam mail that occurs as a result of the real mail address being known.

  For these problems, in order to prevent the user's real email address from being inadvertently known, the user's real email address is stored in advance in a specific service server, and the real email address is stored by e-commerce or the like. When required, a method is disclosed in which the user presents only the URL of the service server that stores the real mail address (see, for example, Patent Document 1). In this method, when the electronic commerce company accesses the URL of the service server, the service server pays out an appropriate mail address among the mail addresses held by the service server as the user mail address. Therefore, when the e-commerce company sends an e-mail to the user mail address corresponding to the paid-out user, the service server receives the mail addressed to the user e-mail address and uses the user e-mail address as the user's real mail. Replace with address and send to user.

  As a result, the user does not notify the e-mail trader or the like of the real e-mail address, so that the concern about leakage of the real e-mail address can be reduced.

JP 2005-341177 A

  However, in the method described in Patent Document 1, since the user is not informed about the equivalent of the user mail address, there is a case where even the mail address paid out cannot be used effectively. In other words, when a user sends an email to the other side, the user cannot send the email using the equivalent of the user's email address, and is forced to use the real email address, and the real email address leaks from the other side. Worry remains.

  Here, in order to prevent the real address from being inadvertently leaked from the other party who sent the mail, there may be a method of setting this mail as a confidential mail when the sender sends the mail. . By making the other party's terminal device that received the confidential mail inaccessible unless a personal identification number is entered, it will not be possible to see the mail even if it is lost or stolen. E-mail addresses can be prevented from leaking. However, in this method, the terminal device on the other side that has received the confidential mail needs to be a dedicated terminal device that receives the confidential mail, and is not generally applicable, and there is a more convenient method. desired.

  As described above, in the conventional mail service providing technology, the user cannot send a mail corresponding to the user mail address even when sending the mail. However, it cannot be used effectively, and there is a problem that a real email address is still leaked.

  Therefore, the main object of the present invention is to solve the above problems, and even when the user uses a plurality of e-mail addresses separately from the actual e-mail address, for example, for a plurality of e-mail addresses and accompanying messages.
