Yeah. That's great -- as long as we're not talking about the general
case, as you say. If we're only talking about Phish, it's fine. It's
only when you apply it in general to all incoming mail that it starts
throwing away valid mail.

Actually, if we know we're only talking about Phish, we could go one
better -- we could just reject it all.

Except of course that we have to have some way of telling it apart from
genuine mail, in the general case.

Can we talk about the general case now?
