[cabfpub] For Discussion: S/MIME Working Group Charter

We seem to have a terminology issue here. What is a server? This is obvious in HTTP but far from obvious in the context of email because there is an inbound and an outbound ‘server’ and it acts as a client and a server at different times.

 

I agree that certificates used to authenticate Mail Transport Agents are properly part of what the Server WG is specifying. But they may be used by a host acting as a TLS ‘server’ or ‘client’.

 

 

Another little oddity is that we are assuming that the entity a CA validates and issues certificates to in the S/MIME world is properly the end user rather than the organization. That might not be the right approach. If what the CA is effectively validating is ‘example.com’, and not ‘alice@’, maybe it is better to perform validation on the organization.

That's clearly the remit of the Server Certificate Working Group, and should remain so.
