But I don't WANT another person to spoof my mail address.  Why should a
mailing list be any different?

great! :)

No, DMARC points at one/both of the other two.  It's not a parallel.

I mean, sure, it breaks lists.  But the lists were already broken, and yahoo
is just saying "we want it done right."  It would be unfortunate if they lose
people because of doing the right thing, technically.

Is it so hard to change from to the address of the mailing list (which the 
email REALLY IS FROM, and set the reply-to: to the original author?  That
sounds like the right thing, to me.

This email sent from gmane, which is going to LIE TO EVERYONE and claim I
mailed it.
