I took a different approach. I left the bounce detection on
but switched all @yahoo.com accounts to digest mode. Since
the mail now comes from the list instead of the @yahoo.com
sender there are no rejections. Not a perfect solution but
it prevents harm to non-(_at_)yahoo(_dot_)com list participants.
IMO, this is quite elegant. The Yahoo users continue to get the
messages, you don't get cluttered by rejection-related
complaints, and those Yahoo users who don't like the digest form
can take it up with Yahoo or find other accounts to use.
The issue with @yahoo.com and DMARC is not the @yahoo.com users' ability
to receive mail, it's their ability to send mail to the list with From:
*@yahoo.com and have it be received by list subscribers who implement
strict DMARC policies which honor Yahoo!'s p=reject.
It's not clear how setting the @yahoo.com users to digest mode helps
this situation at all.
