  • E-mail processing method
    Patent number: 6332156
    Abstract: An e-mail processing method for transmitting an activity program along with data, to thereby perform various forms of activities upon reception of e-mail. The sender first creates a message having a message header and a message body including data which is to be sent to a receiver. If the sender wishes to designate an activity for the receiver, the sender creates an activity program to perform the activity, attaches the activity program to the message, and sends the activity program along with the data. When the receiver receives the message, it is determined whether the activity program is attached to the received message. If the activity program is attached to the received message, the activity program is executed.
