If it is, that's fine, but it doesn't have to be, and we need to
handle that case too.
That's what Arvel proposed, Jim:
Yes, but suppose that the Sender header were used only when the domain
found therein matched one of those in the From.
I'm still missing a suggestion for what we use when the Sender header
field does not match any of the addresses in the From. Do we then
revert to First Author? All Authors?
