Unfortunately as with most messenger services, they scan all available ports for an open one:  Yahoo is one of them....here is what they say on their website.

It will be impossible to block traffic unless you stop internet access.  Another route might be to block yahoo traffic.  This can be done through DNS entries pointing users to a non-existent or internal IP so that they are not able to correctly resolve yahoo servers.  And the same can be done with MSN.  You can use group policy to prevent users from running these applications....you can look at group policy by going to Start --> Run --> gpedit.msc.
