o For 2821, we will either pick HELO or MAIL FROM, but
not both as
they have different meaning. In the case of a null MAIL FROM, the
receiver has the choice to abandon the MARID check or drop
back to 2822 checking.
Someone please explain why checking HELO, in case of _null_ MAIL FROM, is a
bad idea.
Otherwise, I really like the acknowledgement that the receiver will decide
which identity to verify.
