Situation Analysis
Lost in the media brouhaha surrounding Email use by secretaries Clinton, Colin Powell, and Condoleeza Rice, the bigger issue of Email and the vulnerabilities it introduces remain lost.
It should be a well-known fact by now that phishing scams are the dominant mechanism for compromising our privacy and security. It's a lesser known fact phishing is fundamentally a social-engineering technique that leverages the inability of an email receiver to verify the identity of an email sender.
You solve the issue outlined above by digital signing email messages. Once in place, email receivers can even build additional protections based on filters that incorporate digital signatures.

Because self-signed emails are generally disallowed by email packages like Thunderbird.
