[CentOS-es] Postfix no saca mis mails

[angel jauregui]

Buenas.

Monte un CentOS 6 e instale Postfix+Dovecot+Saslauth, he abierto los
puertos tanto para conectar a los buzones como para el envio de correos,
aqui un escaneo de como luce desde afuera:

21/tcp   open  ftp
22/tcp   open  ssh
53/tcp   open  domain
80/tcp   open  http
110/tcp  open  pop3
143/tcp  open  imap
993/tcp  open  imaps
995/tcp  open  pop3s
8080/tcp open  http-proxy

Tengo muchos abiertos porque mi servidor funje como router tambien, para la
red interna mi servidor es un ProxyWeb, FTP, DNSMasq (dhcp), HTTP (uso
Virtuales) y Correos.

El puerto 25/smtp aparece como *filtrado*.

Regla que uso para el 25 en iptables:
*iptables -A INPUT -i eth0 -p tcp --dport 25 -j ACCEPT #smtp*

Cuando envio un correo recojo esto en el log:
