Abstract
According to an electronic mail system of the present invention, if destination limiting information is included in a header of an electronic mail received from a mail client, a mail server identifies destinations designated in the header of the electronic mail into those within a transmission available area and those outside the transmission available area based on the destination limiting information, and transmits an electronic mail only to the destinations within the transmission available area. In this way, since the electronic mail is transmitted only to the destinations within the transmission available area, even if a destination is wrong, the electronic mail is prevented from reaching the wrong destination and secrecy of information in the electronic mail can be kept.
