You don't have to remove the List- headers. DKIM says what headers it's

Any Header or Body changes will invalidate most, if not all, DKIM
signatures. Since DKIM is used as part
of DMARC, it's a problem.
Not sure what MajorDomo2 will allow you to do.
We can turn off header and body changes easily enough, but changing the
"From:" address requires patching the Majordomo2 source code; and, as
you may already be aware, the maintainers gave up on Mj2 a decade ago,
so we'd be on our own for that. I cannot promise any sort of timeline
for getting that done; and since that's an essential part of the
I don't see any point in doing the other changes either for the time
I think the breakage of DKIM signatures is already causing some pain
(though nowhere near the level of DMARC).
Of course, removing all the "List-" headers *and* our custom footers is
a huge step backwards in terms of mailing list functionality :-( Also,
removing the [HACKERS] etc tags will annoy some people, for sure.
