I hate to have to do this, but I own an apology to Paul Johnson.
(Having received a mail from a list member with an example of a false CR. Talk

A real one will have:
Subject: Re: The_Subject_of_Your_Original_Message
AND the Reply-To: header will have the address that you mailed it to, making
it simplicity itself to send it back, as well as adding another level of
authentication.
