Cancel messages are sent out as a standard Usenet post, except they contain a “Control: cancel ” header. If a system that accepts cancels receives the message, the post with the specified message ID is deleted from that system. Most major newsreaders allow readers to cancel their own posts with a key press. Third-party cancels are more complicated, and must follow several conventions; please refer to section II.B for details.
