Abstract: In an electronic mail delivery method, a sending computer is operated so as to create an electronic mail and to set parameters of the electronic mail, including address of an intended mail recipient. A connection is then established between the sending computer and a mail-handling server, and the electronic mail and the parameters thereof are transmitted from the sending computer to the mail-handling server. The mail-handling server stores the electronic mail received from the sending computer in a location thereof, and transmits a mail alert message, which includes location information of the electronic mail in the mail-handling server, to the sending computer. The sending computer forwards the mail alert message received from the mail-handling server to a receiving computer of the intended mail recipient. Upon receipt of the mail alert message, the receiving computer is operated to establish a connection with the mail-handling server, and to download the electronic mail from the mail-handling server.
