Due to the nature of mobile terminals, there is a limit to the size of the display unit, and important emails may be pushed out of the screen.Because the data transfer rate is lower than wire communication and communication costs are high, There is a problem in that there are significant time and financial disadvantages. In particular, when using a mobile phone service provider that employs a pay-as-you-go charge according to the amount of transmitted / received data, as shown in FIG. In the case of an e-mail system in which an automatic e-mail delivery service is provided, there is an inconvenience that the user has to bear the reception fee of the unnecessary e-mail. In order to deal with such problems, mobile phone service providers provide services such as switching to an e-mail address specific to the user's e-mail address as a countermeasure against junk e-mail and a partial refund service for packet charges. ing. However, even with these services, it is difficult to completely prevent spam. The reason is that, firstly, if the sender side regulates, the mobile phone service provider is also the customer who sends the junk mail, and as long as the sending fee is received at the time of sending, it is certain that the recipient There is a circumstance that I have to send it to. In addition, when the regulation is performed inside the mail system, there is a situation in which the content of the unsolicited email is not necessarily unique for each recipient, so that it is difficult for the recipient who receives the e-mail to make a judgment. As a technique for solving such a problem, for example, in Japanese Unexamined Patent Publication No. 2000-163341, conditions for emails to be received by a user in advance (same sender condition, maximum mail size condition, sender email address condition, etc.) are set. There is known a mail server that excludes mail under the above conditions. However,
In order to completely prevent unsolicited e-mail with such a device, either the effort to register all of the numerous sender e-mail addresses of unsolicited e-mail, or the inconvenience of not being able to receive e-mails other than known e-mail addresses. You will be forced to bear the burden. Further, the technique of Japanese Patent Laid-Open No. 11-59662 is known as a technique for providing a mobile terminal user with a mail list in a mail server to directly manage the mail, but in the packet communication network of a mobile terminal service provider. Then, Internet standard TCP / IP (T
transmission control Proto
There is a problem that an original protocol is adopted instead of the col / Internet Protocol).

Further, the contents of the electronic mail transmitted to the mobile terminal include the contents of simply contacting the meeting time and place, the contents of familiar conversation between friends, and the like. They often do not have the property of being stored for a period of time. In addition, although the memory capacity of the mobile terminal has been increased, there is a limit, and the user who receives a large number of e-mails is often required to manage the e-mails addressed to the mobile terminal. It is in a state of being. Therefore, it is desired to provide a low-cost and simple electronic mail management means for mobile terminals.
