I guess what I'm trying to understand is why anyone would base their
acceptance or rejection on the 822 From: header. It seems that this
causes mailing list managers to have to jump through hoops to rewrite
the From: header in strange ways.

So, we've been doing dmarc rejects for many years, for Yahoo.com since
they went p=reject two years ago.
We may sometimes override the rejection, but no one should rely on that.
I don't know of anything that has changed recently about this.
Forwarding doesn't break with this unless you modify the mail or the
original message wasn't dkim authenticated. We've seen some recent
examples of banks going p=quarantine while only doing spf auth, which
obviously doesn't survive forwarding.

Sorry for the bad example. We don't use spaces when sending email
out, although
as Jon Postel would have approved, we accept them for incoming
mail. There are a
lot of broken MTAs out there.

Since it has been a common source of errors, it is worth noting
that
spaces are not permitted on either side of the colon following FROM
in the MAIL command or TO in the RCPT command. The syntax is
exactly
as given above.
