I agree.
I'd like a way to advertise to the world, perhaps via SPF records, that
no host will ever validly say 'HELO infradead.org' and to restrict the
hosts which will ever say 'HELO $hostname.infradead.org' appropriately.
This would only be useful to me if I could do it while simultaneously
allowing 'MAIL FROM:<*(_at_)*infradead(_dot_)org>' to occur from _any_ IP
address.
