I'm not quite sure why you want to accept email only from Hotmail and Yahoo, and from nowhere else (a lot of people I know do the exact opposite!), however I still think an easier solution to your erquirement is to accept all email through your firewall, and then accept only mail from Hotmail / Yahoo on your mail server - because that can select based on the sender's address, without needing to know the IPs of their mail servers (which may change one day without you knowing).
