I echo Randy's thanks for technical details.

Just so I do the right thing, do you folks think all mail to be forwarded was silently discarded, or only the mail sent from addresses that were subject to re-writing?

i really appreciate technical details. there are still a few operators
left in the ietf community, and we try to learn from our oopsies. a
deeper post mortem would even be welcome as many of us are also trying
to deal with dmarc hell. you run a medium scale mail operation and any
lessons you share are appreciated.
