As Scott eloquently said, we are not the Internet Police. We need to produce a document that responds to RFC 7960 in the context of DMARCbis. The best that we can do is lay out the options, and let the senders, list operators, and receivers make their choices. We need to move away from fault-finding and SHOULDs, and simply lay out the best options that we can construct.
I submit my recent treatise as the basic outline of that document, simply because the options seem inherently comprehensive: - Never rewrite From - Always rewrite From if the sender policy risks possible delivery failures. - Conditionally rewrite From if the sender-receiver combination makes it necessary because whitelisting status is not granted or not known. All of these options need to be presented well, which means that they need to be presented by someone who can advocate for that option. Baptiste, you should write the case for never rewriting. Any of the long-term participants should be able to write the case for always rewriting and how to do the rewriting. I have more to add about the case for conditional rewrite, but the group has my first draft. To my understanding, ARC, Sender, and Author proposals are variant ways to obtain whitelisting status with the evaluator, and that these only work if (a) the list has feedback that the method will work for a particular domain and (b) the list is able to handle different domains differently. We need advocates to explain how these options provide the most effective way to obtain whitelisting status. What we like or dislike is irrelevant. Difficulty of implementation does not matter. Both are judgement calls to be made by the implementer. Our role is to ensure that they understand their options, along with the advantages and disadvantages of each. Not giving up my opinions, but I am giving up the idea that only one opinion can survive. Let's get the options documented. Doug Foster >
