In many cases you want to use keys to verify that a person today is
the same person that you exchanged messages with in the past.  In such
cases you 'should' add this person to your keyring as it were.

This is what Björn outlined in his last paragraph above.

This identity digital signature/key thing is going to be increasingly
important for people and for systems.   We should pay attention.

Of interest there is a push by Microsoft and others to push an mail
server identity protocol that is not fully "public domain" going on.
IT organizations are rushing to adopt because it might solve some
liability problems but the side effects for normal people are
not clear to me at this time.
