EFW Support

I appreciate the help .. My case is the following router Install and endian and content filtering for a network of 48 teams between mac and pc, I did the startup configurations and I am doing well just a small problem, the endian not let the Microsoft Outlook send emails but instead if you receive it. The ports 25 110 143 993 995 are open in a rule. Then come to the conclusion that the outlook will use another additional port to communicate with the mail server and create a rule opening 1:65000 to realize if he sent, and after shipping.

My question ... What is the port used by Outlook to send additional emails?

Agradezco de antemano la ayuda.. Mi caso es el siguiente, Instale un endian como router y filtro de contenido para una red de 48 equipos entre mac y pc, hice las configuraciones de inicio y quedo marchando bien solo un pequeño problema, el endian no deja que el Microsoft Outlook envie correos pero en cambio si recibe bien. Los puertos 25 110 143 993 995 estan abiertos en una regla. Entonces llegue a la conclusion sera que el outlook utiliza otro puerto adicional para comunicarse con el servidor de correos y cree una regla abriendo 1:65000 para darme cuenta si enviaba, y de una vez envio.

Mi pregunta... Cual es el puerto que utiliza el Outlook adicional para poder enviar correos?

First check where the outlook is connecting, if it is connecting outside (external) than there is a specific port like 25, 995, 143 etc., but if the outlook is connecting to exchange server than none of them ports are used. Its uses MAPI extension by default (cache mode) as I know in exchange 2003...

I just solve open port 465 on the firewall. But it's weird because some do work well and others do not but hey, so I could solve

it's because endian filter outgoing traffic as well...check this -> Firewall -> Outgoing traffic (is my case is just disabled it, I want everything to go out..)
