[CentOS-es] PROBLEMA CON PUERTOS POP (OUTLOOK)

[Departamento de Informática do Concello de Ribadavia]

Buenos días tengo una máquina centos con realizando funciones de proxy/muro de acceso a internet con las siguiente configuración de iptables y squid.
Una vez relaizado en el script de iptables, salvado  y ejecutado con start funciona perfectamente. Pero el problema que no entiendo es que cuando reinicio la máquina y ejecuto service squid start y service iptables start outlook express no me pasa es como si el puerto 110 se cerrase. Que hago mal?. Muchas gracias
