Abstract: Emails are received and the received emails are classified and accumulated based on relay path information contained in the header of each email. For each of the classified groups, a judgment is made according to a judgment rule including at least (1) the number of received emails per unit time is a first threshold or more and (2) the number of emails having an invalid destination address is a second threshold or more. For emails included in a classified group satisfying at least a prescribed number of items of the judgment rule, a mail process including (a) blockage of delivery to the user and (b) transmitting a pseudo error message replicating an undelivery mail to the source is carried out.

Abstract: In the case where a single user selectively uses plural wireless communication terminals by mounting and demounting a subscriber identification card thereon and therefrom, user convenience in such selective use of the plural terminals can be enhanced by synchronizing user data among those plural terminals. For this purpose, at least updated portion of the data stored in the memory in terminal is uploaded from the first terminal 10a on which SIM card (subscriber information card) 12 is mounted, to a server 50 via a communication network 20, according to a user's request or automatically. After the SIM card 12 demounted from the first terminal is mounted on the second terminal 10b or 10c, data to be downloaded to the second terminal from the server 50 is determined according to the user's request or automatically, and the data is downloaded to the second terminal from the server 50. In the second terminal, thus downloaded data is used to update the contents in the memory.

Abstract: There is provided a method of laying out contents targeted for a first device having a first screen size on a screen of a second device having a second screen size smaller than the first screen size. The method includes analyzing a table width of the table in accordance with a predetermined criterion; and performing in response to a result of the analyzing step one of layout operations of: (p1) laying out the table using a typical technique in accordance with the second screen size, and (p2) laying out a row of cells in the table so that at least two cells arranged adjacently in a horizontal direction in the row of the table are aligned horizontally on the screen of the second device based on a predetermined algorithm.
