The consensus is that it is hopeless. There are several views
of the reasons, with the one I think most credible is that Yahoo
has become so focused on anti-spam and anti-phishing efforts
that they simply do not care about anyone else or the users of
any other mail or mailing list provider.

If you are interested, you can find a long thread on the IETF
list about mailman, Yahoo, and restrictive DMARC policies in
general. The archive is at
https://mailarchive.ietf.org/arch/browse/ietf/ and you should
probably search the last month or so for "DMARC".
