A terminal operated by a user is connected to a server group, including a management server, a mail server, and a database server, via the Internet. In the database server, current account information, including a mail address of the user for mail exchange is registered. When the user registers a new mail address in the terminal, the new mail address is notified to the mail server and the database server. The database server updates the registered account information and also updates the account information registered in the mail server. The update of the account information in the server group is notified to the terminal. When the update of the account information is notified, the terminal apparatus requests the database server to send the account information. The terminal internally registers the account information sent from the database server in response to the request. |
