AFAIK no-one is arguing that it *shouldn't* be (in the sense that in some ideal alternate universe we wouldn't want it to be), but that it *isn't*. And to say "there's no excuse for it not to be" is either a misstatement of what you mean or evidence of a jaw-dropping misunderstanding of how the Internet works. As I can't believe you really mean the latter, I guess it must be the former. Or maybe we have different conceptions of what "reliable" means. As I pointed out in an earlier message, there are situations in which not using greylisting leads to a measurably less reliable mail service. Not all situations, maybe not your situation, but I know they exist because I've seen them. poc
