:-) If not that, they the black hats could/would/did just add
DKIM+SPF+DMARC to their own yaaho.com, yahho.com, yahooo.com, etc.
domains. After all, Granny Smith never looks at the domain, she just
looks at From: "Flower of the Month Club" (which is likely long enough
to push the <flowerofthemonth at yahooo.com> right off the right side of
the header field.
In 2 years people will be wondering how DMARC did hardly anything to
slow miscreants, just like some wondered why SPF, DKIM, PGP, SenderID,
etc didn't solved all of mankind's problems.
