1.) is my understanding of what TDE does. Here are some of the {snipped} TDE
headers:
Return-Path: <trinity-users-return-{snip}@lists.pearsoncomputing.net>
Envelope-to: {snip}@inet-design.com
Reply-To: trinity-us...@lists.pearsoncomputing.net
From: Michael <{snip}@inet-design.com>
To: trinity-us...@lists.pearsoncomputing.net
X-Get-Message-Sender-Via: srv04.srv04-inet-design.com: authenticated_id:
inetd/from_h
X-Authenticated-Sender: srv04.srv04-inet-design.com: {snip}@inet-design.com
My guess is it's either, or both together, Reply-To or Return-Path that make
the desired behavior change. Based upon the email ‘From: chillfan’ here that
doesn’t work that has in the headers:
Reply-To: chill...@protonmail.com [1]
instead of no ‘Reply-To:’ at all for messages here that do work.
(Return-Path seems to already be set.)
(Added the X- as TDE seems to authenticate me as a sender, where Devuan
doesn’t. No real idea if that’s relevant.)

As we seem to be way over thinking this....
Suggestion: Just try adding, or replacing if already present, the ‘Reply-To:’
for all messages with the value:
Reply-To: dng@lists.dyne.org
That’s not going to break the list, and will answer the question immediately.
Best,
Michael
[1] I would mangle that, but it’s clear text in the original.
