Yes, what Stephen says is correct. It would be a simple matter to add
say a dmarc_wrapped_message_text field which text if provided would be
added as a separate MIME text/plain part along with the wrapped message
when the message was wrapped due to dmarc_moderation_action.

What I was saying was "too messy to contemplate" was the notion of
sending the post with the original From: to all recipients and then
resending a wrapped message only to those recipients that bounce the
original.
