In reviewing your response to John, I'm thinking that part of the initial 'orientation' work of the draft -- probably in section 3.1 -- should add to the description of the components (origination, MLM, receiver) by documenting the different scenarios that will be covered, primarily to indicate that basic types of choices or effects created by having an MLM in the sequence. The goal would be to give the reader a snapshot of each combination, so that that will be in there head when they read the details. I think much of the challenge of this exercise is deciding how to organize things, so that readers see the problem space partitioned helpfully and, therefore, get useful chunks of guidance. Otherwise it's all overwhelming. The following list is much longer than I'd like, but I think each entry is for a scenario that is distinctive and significant. (For reference, I've left some combinations off, since they didn't seem compelling to me.) DKIM: Broken Broken Signatures: Origination DKIM -> Non-participating MLM -> Receiving DKIM Submission enhancement: Origination DKIM -> Participating MLM List reputation: Participating MLM -> Receiving DKIM End-to-End DKIM: Origination DKIM -> Participating MLM -> Receiving DKIM Besides a discussion of each of these on their own, the possible relationship between Broken Signatures and End-to-End DKIM would be helpful in terms of the Origination signature. I think that, in fact, they produce the same result, namely a broken signature. ADSP: Broken ADSP: Origination DKIM+ADSP -> Non-participating MLM -> Receiving DKIM+ADSP Submission ADSP: Origination DKIM+ADSP -> Non-participating MLM End-to-End ADSP: Origination DKIM+ADSP -> DKIM+ADSP Participating MLM -> Receiving DKIM+ADSP I don't feel religious about this list. Anything that works is fine. The combinatorials of this problem space are confusing and I'm simply searching for a way to divide into smaller bits that are easier to digest. d/ -- Dave Crocker Brandenburg InternetWorking bbiw.net _______________________________________________ NOTE WELL: This list operates according to http://mipassoc.org/dkim/ietf-list-rules.html
