Charles, just a quick answer as we are really OT. It all simply boils down to (quoting me):
> avoid unnecessary processing and avoid unncessary traffic. and I might add now: with the least disadvantages on both sides. Assess that and you find it doesn't make sense to spam-scan messages and reject them in/after DATA stage in a real world scenario. It makes only sense if you are die-hard spam-fighter who wants to "retaliate" and doesn't bother if it makes sense. And that is indeed very misguided. Most if not all of your arguments are arguments for spam-filtering mail, not in favor of rejection at DATA stage. Last, keep in mind that filtering mechanisms in whatever stage are not solely meant for rejecting or spam-fighting, they are for *filtering* and then assigning appropriate actions - which often have nothing to do with spam/malware detection at all.
