[ietf-dkim] MLMs and the use of multipart/alternative to preserve original DKIM signature and at the same time add a new DKIM signature

[Bill.Oxley at cox.com]

I trust the reputation and blame the reputation of the MLM as a single standalone author. I have no interest in the contributors reputation. As a receiver who is on many lists I unsubscribe when the list no longer meets my viewing needs. As a admin of mail systems I dont want to interrupt that flow unless virus or spam is egregious

The only dkim sig I am interested in is ietf-dkim at mipassoc.org and if I bothered to check adsp for etf-dkim at mipassoc.org I wouldnt waste time checking any other signatures/adsp assertions from participants as I see a mailing list as an aggregator.

I would be asserting that etf-dkim at mipassoc.org is the author/aggregator not a forwarding service. Trying to have 3rd party in a hands off transaction assert or check that the authoring party may be who they say they are and making decisions upon adsp discardable that may or may not be valid is beyond any sensible solution.
