I'm using gpg to sign my messages. It is an open source produce produced by the people at gnu. So if you want to verify that an email actually comes from me, check it against my public signature given below. (I've also put my key on a public server or two, but haven't ever gotten it signed. So all the public server does for it is it allows one to check that it hasn't changed in several year.)
Eventually everyone will sign their message as a matter of course. Or at least anyone who wants you to know who they really are will sign their messages. The only people who regularly send me emails that probably don't want me to know their real address are spammers. So eventually a mail filter that doesn't pass messages that are unsigned should remove all spam. Now that is the correct way to end SPAM/junk email! No government intervention needed.

In an ideal world, you would have gotten the above fingerprint via some hardcopy or possibly over the phone. Possibly printed on the backside of my business card. In that case, you could download my public key, and then ask your software to generate a fingerprint. If it didn't agree with the printed copy, you would know that you had been attacked by a "man in the middle" attack. Feel VERY special! To my knowledge, no-one has suffered such an attack (yet).
Putting the fingerprint here is totally useless for security purposes. But for fun, you can check that it matches my public key below:

Here is a quote from the University's Policy on Privacy in the electronic environment: "...property authorized university officials.... may access e-mail, voice mail or computer accounts in cases of alleged...violations of university policies." Later it goes on to say that "email users may want to consider... encrypting personal messages."2
