The authors of ARC think it more directly applies to the issue of list mail. Let's start from assuming that they might have a point and we'll see how the first implementations of this work. But, if it doesn't really address the issue, it's pretty easy to ignore. Most MLM tools that want to keep working have already implemented DMARC workarounds -- I can't see those going away unless ARC provides a better alternative. And maybe not even then, who knows. >From my own perspective, I'm unclear on how well this will work. I assume the chain process is based on addressing anything thrown at at it; mailing list posts going through mail forwarding; ARC on both would in theory keep authentication intact and prevent p=reject policy rejections. But we're talking the 1% of the 1% (of the 1%?), it feels like the use cases might get more and more far out.
