Bloquear yahoo messenger

me di una vuelta por los log de squid los de los usuarios que se conectaban a yahoo y logre extraer algunas ip donde yahoo establece conexion, tambien busque algunas por internet dando un lista de mas de 200 servidores

esta lista la pase un txt para bloquarlo desde esquid algo asi

acl ip_yahoo url_regex "/etc/squid/yahoo.txt"
http_access deny ip_yahoo

y en iptables una pequeña rutina para bloquear las salida

while read yahoomessenger ; do
iptables -t mangle -A PREROUTING -d $yahoomessenger -j DROP
done < /etc/squid/yahoo.txt

esta la solucion para olvidarme del yahoo messenger espero le pueda servir a otros

Saludos

NOTA: adjunto lista de ip a bloquear (sorry si es muy largo)
