But the problem case in our off-topic rabbit trail meanderings is that
people who "have control of all their sending" still don't necessarily send
mail of consistent seriousness nor do they have any control of the paths by
which that mail takes to get to the ultimate recipient. There is a
conflation of "control of emission" with "control of path".
