This is indeed useful. But I think it's also important to look at technical vs. nontechnical costs for each actor. The whole reason we're having this discussion is that a few large originators had nontechnical costs that they decided to push off onto other people.* The most tedious and unhelpful discussions here have implicitly (or perhaps explicitly) assumed that receiver nontechnical costs don't matter, then repeatedly pointed out the true but useless fact that there are single party mediator changes with trivial technical costs. R's, John * - the essence of Internet economics is forcing as many of your costs onto other people as you can, but that doesn't make it a virtue _______________________________________________ dmarc mailing list [email protected] https://www.ietf.org/mailman/listinfo/dmarc
