First, install the Jon's Command's scripting addition (version 3 for OS X,
version 2 for OS 9) if you haven't already. It is freely available at the
author's website.

Then, get the "Add BCC or CC" script by Paul Berkowitz. It includes setup
and usage instructions. All you have to do is run the script whenever you
open a new message to have yourself added as a CC recipient.
