Murray, This is very helpful, thank you. I find section 7 easier to follow than Kurt's pseudo code in https://tools.ietf.org/html/draft-ietf-dmarc-arc-protocol-03#section-5.1.1.5.1
Quick bug (I think): In 7.5, you say "If no seals pass validation" but I think you mean "If all seals pass validation". Additionally there is a discrepancy between your section 7 item 5 and Kurt's pseudo code. As I'm reading it, your logic allows a chain with a cv=pass at i=1 to be valid, and Kurt's does not. I believe Kurt's is correct, especially based on your definition of the cv=none value in 5.3.1 of your draft. Thanks! Sure I'll have more feedback soon, Seth On Thu, May 4, 2017 at 12:56 AM, Murray S.
