Because, I quote:
"Well, you could just
deny domains = those_domains
!hosts = +allowed_hosts
but if I understand correctly, that would also stop accepting mail for
those_domains from any relay_from_hosts or authenticated users, which
may not be the desired effect."
Yes, I need to accept connections from authenticated users.

I can tell there's stuff being sent directly to Exim; those messages bear
none of the headers that they'd have if they came through the spam
filters.
I only made the change recently, and I'll bet there's a lot of ratware out
there that still has the old MX record cached. justthe.net is a good
example; the MX records all point to cleanmessage.com now, but there is
still spam coming directly to mx.justthe.net (my Exim box) even though it
is not publically advertised in DNS anymore.
