My point is that the draft is already peppered with scenarios about how MLM can break things and it properly classifies the known simple list-like type of alias address expanders that in general, the messages is not altered. Of course, we all know its not the only kind; a real List Server always provides list admin options to not alter things like the IETF-SMTP list seems to be been setup (with mailman?). But here, it appears it does add a extra CRLF after the headers. So my question is about whether we should provide an informative implementator insight that there may be an extra CRLF generated by non-DKIM aware list. It can make all the difference in a valid versus invalid DKIM signed submission to a non-DKIM aware MLM, which BTW, I did add logic to my verifier to check for this extra CRLF when a BODY_HASH error first occurs and redo the hash without it. It works! But I am probably going to add a condition based on LIST-ID to enable this check. I fail to see why we would not be interested in giving verifiers some insight into this real live scenario.

The author can be a human using an MUA (Mail User Agent) or a common system utility such as cron, etc. If the intent is to suggest to the readers there is something special cron when it comes to the author, i.e. may not be real author or not exist, then I can see it may apply. Bu I don't think that is what you were trying to say here. I think what you are essentially saying here is the distinction between a Human (UI) Agent and Automated (no UI) Mail Agent. So perhaps the last sentence could be restated : The author can be a human using an MUA (Mail User Agent) or an automated mail robot with an MTA. I just think for this MLM I-D which already requires a high-level of intelligence, makes that part unnecessary. Perhaps you can also state also like you did with originator (and may for verifier): author: The agent that provided the content of the message being sent through the system. The author delivers that content to the originator in order to begin a message's journey to its intended final recipients. This authoring process is often referred to as the Mail User Agent (MUA) or MTA sending mail to the MSA or MDA.

Re: [ietf-dkim] MLM and C14N
Do you know what is being asked? I think everyone understands what you're asking. They just disagree, and so do I. When all this started, before DKIM came to the IETF, and then again afterward, we spent a *lot* of time looking at the canonicalization algorithms -- and they were changed a bit after the work came into the IETF. We didn't come by them casually. Throughout it, there were a few goals in choosing canonicalization algorithms: 1. We didn't want more than one or two. This obviously never did nor never should take precedence over a true need for another one, but the idea is that the bar needs to be very high for a new one. The combinatorics get messy. 2. We wanted to cover the vast majority of the cases, though we knew there'd always be outlying situations where some mail would get broken because what we had didn't *quite* cover some other case. We decided to accept that. 3. We absolutely did *not* want to go adding new algorithms for this or that piece of software that was getting something wrong. Canonicalization algorithms were *not* designed to work around broken software. They're meant to deal primarily with legitimate, if sometimes unfortunate, changes that get made to the mail along the way, and secondarily with *very common* situations that creep into the questionable area. A real live LIST organism (stream) is adding an extra line (two bytes, CRLF) after the header and before the body probably all its life It's an outlier, off in the weeds. This is not a common situation all around the Internet. And in any case, the MLM document isn't the place to define a new algorithm. This is surreal. Don't shoot the messenger, listen to the message! There's nothing surreal here, and, again, I ask you to stop being extreme and inflammatory. Calm discussion, please. Anyway, we *are* listening to the message.
