This example prompts the user for addresses needed in the message envelope (`To' and `From' addresses), and the message to be delivered. Note that the headers to be included with the message must be included in the message as entered; this example doesn't do any processing of the RFC 822 headers. In particular, the `To' and `From' addresses must be included in the message headers explicitly.
