Abstract: The automatic e-mail notification system provides for the automatic notification of an e-mail recipient of the presence of e-mail in the recipient's e-mail box on a remote e-mail server. The automatic e-mail notification system comprises an e-mail server connected through a computer network to one or more computer systems for receiving e-mail from the computer systems. The e-mail server is also connected through the computer network to a mail notification server and a notification device at a recipient's location. The notification device is activated and deactivated by a signal from the mail notification server. The e-mail server generates and sends a data signal containing a message received signal or a message retrieved signal to the mail notification server.
