Abstract

A plurality of mail servers are registered along with a priority order, and normally, a mail server is selected in accordance with the priority order, and the electronic mail is transmitted. When a failure generates in the selected mail server, the electronic mail is transmitted by using a mail server of next in order. When failing in the transmission of the electronic mail via the selected mail server, it is determined whether to select a mail server of next in order, to establish a connection again with the mail server that was selected at the time of the failure in the transmission of the electronic mail, or to cancel the transmission, in accordance with contents of the failure. Since a plurality of mail servers can be used, even when a failure generates in a mail server, the electronic mail can be transmitted by using another mail server.
