That's not always trivial.  I get plenty of back scatter, and I've tried 
to do this to reduce that, but I've been unable.  My domain is for my 
family, so each person is in a different part of the country using 
numerous paths to send out mail (local ISP, gmail, web-mail through my 
server, a roaming SMTP service, various cell phones, blackberries, 
etc.), so I've not been able to come up with a complete list of what 
machines can send valid mail from my domain.
