  • Blocking a "reply to all" option in an electronic mail system
    Patent number: 5872925
    Abstract: A "Reply to All" command may be selectively blocked by a sender in an electronic mail system. The "Reply to All" command may be disabled in response to selection and enablement of a "Block Reply to All" option when the message is composed by the sender. After the sender transmits the message, the message is displayed in a window on a computer operated by a receiver. If the "Block Reply to All" option has been enabled, then the "Reply to All" command is disabled at the computer operated by the receiver. The disabling of the "Reply to All" command may be visually represented by a change in the display.
