  Where can I get a certificate for mail.example.com <http://mail.example.com/> 
that is (a) trusted by end-user systems, and (b) is limited to 
id-kp-This-Is-A-Mail-Server?

  What happens now is one of 3 things:

1) use a web cert, and lie to the CA/B forum about what you're using it for.  
This (allegedly) means that they can revoke it at any point for mis-use

2) use a private CA, and have everyone else on the Internet refuse to talk to 
you, as your CA is unknown

3) don't use TLS.
