S/MIME is an SSL-based MIME extension, developed by (I think) RSA Data
Security.  It attempts to do the same sort of stuff as PGP - allowing for
encrypting/decrypting and signing of emails.  pkcs #7 is the data format.

Outlook comes with support for it built-in, and PHP has some new S/MIME
functions built-in if compiled with openssl support.

I think there is more info at openssl.org
