The EAI WG found it was fine to remove the obligation to have an email address part in the mandatory RFC5322.From header, leaving only the display part to assert the original author. 

So it seems that "IETF" is not completely in agreement on how to preserve the original author in emails. 

So I think the example showed by Terry is as good as what is in EAI and this is a matter of taste and UI designs, UI design and functions that usually the IETF avoids to deal with...

If you hit “Reply-All”, at least when I use Gmail, it includes both the From: and the Reply-To using the scheme below (I tested it out just now). In Outlook desktop I have to also copy/paste the From: address (mailing list). It’s not ideal in Outlook desktop, but I can live with it. 



In this email discussion, I hit Reply-All and includes Ted on the To:, and dmarc@ietf.org and ietf@ietf.org on the cc.

And if there were something like this in other headers that retains the original senders: 





Reply-To: originalSender@example.com 
Sender: dmarc < dmarc-bounces@ietf.org > 










I don’t think this is quite right—I think the Reply-To needs to include all of the senders or else every reply will be an off-list reply (would cut down on noise, admittedly). Otherwise this would be a great solution. But because of the way it interacts with MUAs, I do not think it would work in a way that doesn’t violate the principle of least surprise.
