Sorry, I forgot to put in the footnotes indicated in my message.
I will add them now (unfortunately repeating much of my original).
They don't affect the substance of what I wrote, (otherwise they wouldn't
have been footnotes), but they do forstall some misunderstanding of what
I said.

Notes: [1] Yes, I know that MD should probably not be considered the
"originator", but there is a reasonable sense in which it should be
considered something like an originator and it is in that sense that
this concern is relevant.
[2] Here I am explicitly making the distinction between host and server.
often we can get away with conflating the two, but the concern is about
processes run by ordinary users that pretend to be MTAs injecting mail.
[3] Subject to the relaying constraints and other checks that the server
makes.
