1. Interface

When a program (or a person) wants to respond to a message -- reply, follow up, forward, cancel -- the program (or person) should just put point in the buffer where the message is and call the required command. Message will then pop up a new message mode buffer with appropriate headers filled out, and the user can edit the message before sending it.
