"What *identity* is it that needs to be authorized".

First off I understood the problem statement was about authentication, not
authorization.  There's a difference: authentication is who you are or who
you represent, authorization is what you're allowed to do.  In SMTP I'd still
want everyone to be allowed to send me mail, I just want to know who they are
or who they represent first.



Exactly, authentication is about who you are (here: IP address), 
and authorization is what you're allowed to do (here: use e-mail
address). 

But many people use "identity" for the e-mail address.

So my question was whether he was talking about the IP address 
or the e-mail address when talking about "identity".
