You seem to be suggesting ignoring it, and/or kicking yahoo subscribers (or blocking them from posting.)

I have both an earlier comment, and a later comment.

Later in this thread, I said:  " A recipient on gmail (or whatever) will reject the post from the yahoo user, and *send a bounce.* [...]  I am pretty sure the mailman default behavior is to unsubscribe users that bounce, after a few tries."

Earlier in this thread, I said:  " This policy actually makes sense, and will be increasing in the future.  It's only a matter of time before google and everyone else do the same."

Have you looked into who's behind creating DMARC?  AOL, Google, Microsoft, Yahoo, Facebook, Comcast, and others.
