It's still not graylisting. [...] The "refused to talk to me" makes it clear that my server didn't even get a greeting, but above error message instead. So, yahoo doesn't even know who the sender or recipient is. Ie, the whole thing is IP based.
OK, that's a lot more punitive than they make it sound.
The problem that Yahoo faces is that not only is their hardware distributed, so is their wetware. It's a lot easier for one person to handle a few clues about the easy problems that one person can handle than for an organization to deal with many clues about the much harder problems of scaling to Yahoo size.
I know it's not easy. I see what kind of problems i have with only one domain. But yahoo could at least talk to me in a proper way so that we could find a solution together.
You're anthropomorphizing. There *is no Yahoo* that can talk to you in a proper way. Only employees. Look at it this way: a bureaucracy *is* like a machine, so designing an organization in which the employees behave like human beings toward non-paying-customers is very similar to writing a good UI for a large program --- but orders of magnitude harder. And you know how hard UI is.
I dunno, it sounds like all we can really do is boycott Yahoo, as you suggested in the first place. Whether they'll care, I don't know.
