 That net mask should be 255.255.255.0 not 255.255.255.255
 Yahoo Messenger uses differnet ports to connect - 5050,25,37
 
 Also the ipblock that it currently (here in Aust anyways) connects to
is 66.163.169.0/255.255.255.0
you could use that in your iptables rules.

 squid by default should be blocking 25 and 37
 
 also in squid block http requests to
 *.msg.yahoo.com
 to stop them from using http proxies :)
