Full disclosure: I have multiple mailboxes with multiple email providers
specifically because I want different levels of spam filtering for
different kinds of message traffic. Though it is kind of expensive.
What role standards should play in that sort of conflict over priorities
is murky. There is a lot of value in describing the properties of a
reliable email service. But there's a bit of a "you can lead a horse to
water but you can't make them drink" problem in trying to get operators
who are prioritizing things other than reliable email service to then

could more easily do so. For those that don't want to try, I agree
that we really can't do much.
