Anyone around here been on Usenet in the late 1990s, and remember this on-going flamewar, how spam filtering is detrimental, how everyone has an entitled right to have their email delivered, yadda yadda yadda?

That's what this reminds me of. I'm really getting a sense of deja vu here.

I was around then.      But if you don't think that users care whether their email is delivered, you're not paying much attention to users.

Ordinary users simply don't trust email to work.   They'll use email only as a last resort, and if they really need to send email, will try random combination of sender and recipient addresses (because people often need multiple addresses to try to negotiate the mess).   It's that bad.

they object to. They won't have any effect. People will continue to use spam filtering methods that work for them, and not the ones that some other third party approves of, in some way.

Irrelevant.   For the most part, "people" don't choose their spam filtering; they have it imposed on them and often have zero control over it except to try a different email address.

That was another frequent theme on, circa 1990s – how people are suffering victims of their administrators' draconian spam filtering policies.

Well, those arguments weren't exactly widely accepted back then, and I don't think they're widely accepted now, either.

Just because people refuse to accept the truth doesn't mean it isn't true.

But this is a silly discussion.  I certainly acknowledge that spam filtering is hard, and that the state of the art is to use unreliable heuristics.   The point is, even if it's the best that we can currently do, it still doesn't work very well.   We do no credit to ourselves if we put our heads in the sand and mutter "it's not a problem!".
