I don't agree. There are servers and domains that only send spam. There's no point in passing those through a computationally-expensive filter system; we already know they are spam. > I'd love to never have to ask Yeah, me too. But email is a best-efforts delivery system; email delivery can fail for reasons other than spam-filters.

You don't have to send it through the filter. You can decide @ accept() time that the message will rejected. If you intended to blackhole it; you were planning on burning bandwidth and letting the sender send their bytes entirely, and then responding "2xx OK, whatever" Instead, just simply say "500 FOAD." after DATA and be done with it on the non-zero chance the sender actually has something important to say, and needs to decide if they need to use another channel.
