There was not enough confusion yet, so let's redefine "reject" and use
"refuse" for what others call reject?

Why not simply repair the rfc and let reject do what it should do: give
a 55x error on delivery.
That was discussed on the list. It was a tough call. (Points made by cyrus, kristin, ned, myself, around 13-25Feb04.) Perhaps I gave posts from Ned (then Area Director, I think) too much weight, but I think not. Thanks for the feedback. (Crossposting to make the mta-filters list aware of the feedback. Followups to one list, please.)
