How to block Yahoo Messenger by blocking ports

According to Yahoo's website:

 "Yahoo! Messenger will automatically search the firewall for an open port, and, if it finds one, use that to connect".

The order in which Yahoo Messenger scans for available ports is:

1. port 5050
2. port 80
3. All available ports

This means that blocking Yahoo Messenger by blocking ports will not work. Yahoo Messenger will only switch ports and use a different one.

Even if you were able to block Yahoo Messenger by this method, your employees or students would just change to Yahoo Web Messenger - which is accessed as a web page in Internet Explorer or other browsers using port 80.
