Take a look at DKIM (Domain Keys Identified Mail) which does
precisely that. There is an IETF working group for it, and it is
presently being deployed by people like Yahoo, Google, and others.
There's support for it in SpamAssassin as well as a Sendmail milter.
Go look at <http://www.dkim.org/> for many more details.
