The problem is that the "message" ACL condition is heavily overloaded.
It only adds a message header when used on a "warn" verb; when used on a
verb that rejects a message, such as deny or require, it instead sets
the error that is returned with the 5xx message. On an accept, it's
behaviour seems to be undefined by my read of the spec.
Philip, I think it would be good if warn set a header on an accept, as
well. Can you add that to the wishlist?
Until then, Pascal, you'll have do something like do your whitelist test
in a warn which sets the header and an acl variable, and then test the
acl variable in an accept right after it.
