Are you suggesting that we ignore bounces that can be determined to be
due to DMARC policy. This is an interesting idea and would help prevent
"innocent" list members from being "bounced" off the list, but the cost
would be that these innocent members don't receive some posts and this
happens "silently" so the list admins may not even be aware that there
is a problem. Of course, we could inundate them with notices ;)

I'd be interested in what you come up with for MM 3, and then maybe
consider a backport.

Both FAQs could use tweaking or more. <https://wiki.list.org/x/17891458>
needs more about current options and the MM 3 section at
<https://wiki.list.org/DEV/DMARC> needs a significant update. I suspect
one of us will get to it.
