RE: [Asrg] Its all over for Challenge Response

You could do end to end between MTAs via multiple hops as per 
RFC 3183. 
But STARTTLS is *always* hop-to-hop between MTAs.


If you were going to do end-to-end you would do S/MIME.

But then you have all those headers in the clear anyway so there
is still real value to using SSL.
