Yes, I agree that this is what we are discussing. I think it's pretty clear
that for
Received header fields that refer to the IP address of the end-user, the
answer is "yes,
there should be such an RFC." I haven't heard anyone seriously propose that
this is not
true, although I'd be interested to hear such an argument!
Of course there is such an RFC. RFC 6409 refers to RFC 5321 which
describes the content of the Received header in section 4.4. It
includes the IP address from which the message was received.
If, perhaps, you are wondering if there should be an RFC that updates
that advice to say to do something else, that's totally unresolved,
since nobody yet has made a plausible argument of what to change and
why there would be an overall benefit from doing so.
Until we look at the actual costs and benefits, it's grossly premature
to propose any changes.
R's,
John
