Are you sure these headers were faked? We've discussed spam sent from
Yahoo accounts several times on this list. I've received a few such
messages myself this week.

The sending IP address was Yahoo's and they were signed with Yahoo's
DKIM-signature. These two can't be faked (at least not by spammers).

I think we've previously concluded Yahoo is imcompetent. I have no
reason to assume they're deliberately helping the spammers.
