[postfix-es] Postfix: Connection timed out

[pablo raboy]

Hola amigos.
Estoy montando un Web Hosting "casero", con ispCP como panel de control.
Funciona todo OK, el unico problema es Postfix, que no envia correo.
Estoy utilizando la version 2.5.5, sobre Debian Lenny

El puerto 25 esta abierto, lo corrobore con la utilidad de ping.eu,
ademas hace unos dias monte otro servidor siguiendo la guia
http://how2forge.net/perfect-server-debian-lenny-ispconfig3 y funciono
sin problemas..
Muchas gracias !
