I have thousands and thousands of entries for 66.94.225.* everyday (actual example, 66.94.225.191)
It traces back to yahoo, and that ip appears on no spam lists.
So is this a valid yahoo ip used for maybe their yahoogroups and other internal products?
It definitely is the IP of a Yahoo mailserver (see http://www.dnsstuff.com/tools/ptr.ch?ip=66.94.225.191 -- it resolves to mta296.mail.scd.yahoo.com; "mta" is a term for a mailserver).
I would contact the yahoo.com abuse department about this.
One possibility is that a spammer is sending spam to Yahoo using return addresses on your domain, and Yahoo is bouncing them (I don't know if Yahoo does that, but AOL currently does).
