The functions realized by operating each of 7 are the same as the functions of the reception unit 104, the addition unit 105, the transmission unit 106, the candidate transmission unit 101, the reception registration unit 102, and the addition unit 103 of the mail server system 10 described above. Is.

The operation and effect of this embodiment will be described. Since the additional information storage unit 108 stores user information such as a mail address and mail additional information such as a message and a symbol mark in association with each other, the mail additional information can be specified for each user. Since the receiving unit 104 receives the user information such as the mail address and the electronic mail, it is possible to specify the sending user who is going to send the electronic mail. Since the addition unit 105 searches for additional mail information such as a message or a symbol mark corresponding to the user information of the sending user who is going to send the electronic mail and adds it to the electronic mail, the additional mail information specified for each user. Can be added to the email that the sending user wants to send. Since the transmission unit 106 transmits the electronic mail to which the additional mail information such as the message or the symbol mark is added, the electronic mail to be transmitted by the user can be added with the additional mail information corresponding to the transmitting user.

Since the mail address of the sending user is used as the user information, the sending attempt to send the e-mail can be performed without forcing the sending user attempting to send the e-mail to enter the user information again. The side user can be specified.

Since the mail address includes the personal information part and the group information part, the mail additional information such as the message and the symbol mark can be set in correspondence with either one. For example, when all the sending users supported by the mail server system 10 belong to the same organization, the mail additional information can be searched based on only the personal information part, and the search efficiency of the adding unit 105 is improved. it can. Further, for example, in the case where the mail addition information is uniformly added to the members of the organization to which the sending user belongs (see FIG. 4).
Since it is possible to store the additional mail information corresponding to only the group information portion and retrieve it, it is possible to reduce the information stored in the additional information storage unit 108, and to search the additional unit 105. Efficiency can also be improved.

The candidate transmitting unit 101 transmits the message indicating the social activity or the additional mail information such as the symbol mark to the transmitting side user, and the information and the user information for identifying the social activity which the transmitting side user agrees with the purpose are transmitted. Since the user is received and registered, the sender user and the mail additional information selected by the sender user can be registered in association with each other. Adder 10
3 adds the same amount of donation for the social activity selected by the sender user to the communication charge for the sender user, so that the sender user and the social activity group directly communicate with each other. Donations can be made without giving or receiving money.

Although the present embodiment has been described using an example in which a message or a symbol mark representing a social activity is added to an electronic mail, for example, an electronic mail sent from a certain company is added with the company's symbol mark. Or
A symbol mark representing a license or the like acquired by the company may be added, such as a mark indicating that ISO certification has been obtained. In this case, a donation does not occur, but a certain amount may be added to the communication charge as an information addition fee. Further, the transmitting side user may register with a plurality of social activities and add a plurality of symbol marks or the like. In addition, when adding a message or a symbol mark to an electronic mail, a certain period of time may be provided, and for example, one registration may add only one month.
