Have you tried any sort of reversible rewriting? On my lists, sending
addresses in dmarc'ed domains get a local domain appended on the From:
line, e.g. mail From: marissa at yahoo.com ->
marissa at yahoo.com.dmarc.fail. (Yes, that's a real domain.) Then I do
some local magic so the rewritten addresses work for a few days in
case people write back to them.
It's gross and disgusting, but no worse than any other dmarc workaround.
