Based on specifics (well... more-specific vaguenesses) mentioned by Ryan
elsewhere, I don't believe this is the case.  Chiark appears to be on the
wrong continent to be attached to the user in question, and reducing one to
two seems like a rather incredible off-by-one error to make in this case.

Well, I certainly see a line in that file relating to chiark, but I have no
exim-fu to understand the precise semantics -- and certainly no idea why
it's there, sorry.

No: there is nothing "proper" about rejecting mail from a host that you have
configured to forward mail for you.

... procmail?

Steve Langasek                   Give me a lever long enough and a Free OS
Debian Developer                   to set it on, and I can move the world.
