I had this happen with a new IP block a couple of weeks ago as well. Sign up for the Yahoo! Complaint Feedback Loop on https://senders.yahooinc.com/ and then contact them about your specific problem using this form https://senders.yahooinc.com/contact/. I guess you can skip the CFL registration, but from what I've heard having registered for it will improve your reputation with Yahoo!
They asked a few questions and fixed the problem for my IP block in 3-4 days.
