Let's clarify the purpose of DMARC and the problem of MLM edits:
Thanks for the response. What confusion about DMARC is there, that you felt needed clarifying, and how does it relate to the details of this proposal?
Also, in terms of threats, how does my proposal make them different from what is already considered acceptable? In particular, the current actions by Mediators that rewrite the From: field is, apparently, considered acceptable.
Modifying in-transit messages is a threat vector for both sender and recipient.
Technically, they are not 'in transit'. In basic email terms, they've been delivered and then re-posted.
Also, since mailing lists have been in operation for about 45 years, and since they are such a threat, perhaps you can point to some documented abuses by them?
Lastly, I apologize, but I could not discern any specific substance in your note that relates to the substance of my draft. Please clarify.
