Hence mailing list systems that enforce DMARC, or request DMARC

If you want to participate in such mailing list, one of the best ways
is to change to a mailing list system that doesn't do DMARC.

Thanks for the clear description of the problem - I admit that I got a similar
one from folks at the Seoul IETF.
In the short term, one thing I think would be helpful is to identify for the
IETF participants which email providers are known to use DMARC and maybe also a
list of providers that are known not to. Maybe add it to the IETF mailing
list page at https://www.ietf.org/list/ with an explanation of what's been
happening.
This is a good idea. Taking it a step further, perhaps a warning could be
included when subscribing to an IETF list from an email provider who is known
to use DMARC.
Yes, but that warning should be on the subscription web page, or the
list manager should be tuned to make sure that the warning notice
doesn't get rejected by DMARC!
