I've been able to use PGP with my mail for at least a decade, yet I  
have had very correspondents actually use it.  A few more use S/MIME,  
which I've only had for half that time.  So, a decade on, neither has  
caught on in a meaningful way.  I used to work for a medical center  
in the area and pushed for an effort to use PGP (transparently) on  
_all_ mail and that wasn't a popular even with HIPAA coming down the  
pipe.

A crying shame if you ask me, but doing it at the server level is  
orders of magnitude smaller a project.
