I can tell you that yahoo was one of the services targeted during the
analysis since at the time it was the most popular free email service
here in Taiwan.  This behavior was never exhibited. 

As for this list, it wasn't included.  However, until recently, emails
from lists of fedoraproject came from a single host
bastion.fedoraproject.org and only a single SPF record existed.  I don't
have records from the redhat days.  But, I have my doubts that they
would have had multiple MTA's sharing the same outbound email queue
allowing a different host to re-transmit on failure.
