When you switch to p=quarantine pct=0, no one should apply quarantine (so

There is a reporting feature of mlm-transform that might be worth considering
apart from any indirect mailflow revival. By adding an Original-From: header
field —a copy of From: on the first relay— a domain owner can ask to receive
aggregate reports even if From: was rewritten by a MLM.
Is that what's going on with some of the messages I see on this list? That
seems pretty awful from a security standpoint. Basically you're engineering a
lookalike From address attack. The one big disappointment from my standpoint is
that MUA's don't seem to be using auth-res, etc, to do some basic annotation.
At least Thunderbird.
You need to install DKIM Verifier[*]. It reads A-R and displays some results.
