The IETF lists are an explicitly bad example as they consciously break DKIM signatures *without* rewriting the From: header. For example my DKIM signatures will be broken down the line -- i do not have a DMARC DNS entry --, noone cares for that. That is the worst possible way of doing things, really. In which "isolated space" can someone *think* that?? (I will forward this email to [rt5.ietf.org #38946].) With DKIMACDC the status quo of properly administrated mailing-lists at least remains the same, it is just that the user interface of receivers *can* adapt. However, over time it *may* become possible to do better, but this is not part of the (still incomplete) draft. |But again, my original point on this sub-trhead is that Author: is |trivial, not fragile, and based on constructs that have been used in |email from its start.

It is, as i said many times before, sheer unbelievable that those giants which prodded for that immature, inconsistent technology do not care for at least this little sanity!! (P.S.: off-topic to your email etc, but i read the review of the DKIM2 document -- i actually did not know it before --, and in my opinion *that* DKIM2 is nothing but a continuation of the path of total over-engineering and over-complexity that brought email to the state where it is.
