Apple's mail, and most other email programs, support a standard called SMIME. 
If you install an SMIME certificate in your keychain, you'll then have the 
ability to digitally sign your email and other people can send you strongly 
encrypted email. SMIME certificates are available for free from lots of places. 
I'd go with a well-known source like Comodo for more security.

You can also use PGP to do the same thing, but Apple's mail has no built-in 
support for it.
