Please stop.

If your messages are getting through (no matter that, at this point, the 
headers are already way more bloated than the message body), then things are 
working as intended.  If you're getting blowback messages to your RUA/RUF 
addresses, that is a datapoint, and is part of the experience.  You will never 
not get those because forwarding is still a thing and there are still broken 
clients and always will be.

If you can point me at an actual problem, instead of just telling me how to run 
our infrastructure, I invite you to contact me privately, and stop wasting the 
time of the people who are here to discuss the actual DNS software or protocols 
that this list is for.

If your messages are being discarded, then maybe you're seeing some of the 
inherent flaws in a system that was built while ignoring one of the most common 
use cases out there at the time.  (It's this.  You're using it right now.)

SPF (with both TXT records, and SPF records) were flawed.  SenderID (which 
built on SPF) was flawed.  Domainkeys were flawed.  ADSP was flawed.  DKIM was 
flawed.  DMARC remains flawed, and ARC has the "okay, people can arc-seal 
things but how do we know we can trust that ARC seal?".  

Well, we're a non-profit that runs critical internet infrastructure since 
before Gmail was in beta (did it ever come out of beta?).  If you can't trust 
us, don't use our mailing lists, or our software.

And no matter what, scamming people is a billion dollar industry because the 
MUA's, by default, still hide the fact that you have a FROM line like:

From: "Company President" <[email protected]>
Subject: I need you to buy gift cards as a treat for the company.

...and disable any critical thinking in the recipient because they just display 
[Your Boss]

At this point, most people doing DMARC/DKIM are doing it so they can deliver to 
Gmail and o365, who still are black boxes that break regularly -- and I know 
there are some names on this list that I also see on the relevant lists related 
to running mail servers, that are witnessing it first-hand.
