I think you're being too extreme in your analysis here. Even if
the various systems you list are used, there is no reason (except for
challenge/response) that we need to assume that the failure of a system
to support one or another method would cause mail to be discarded. Such
mail can be put into a "suspect" or "gray" inbox -- making it a bit
harder to get to, but still not getting rid of it.
