i take it 192.168.1.254 is your router ? it could be your ISP blocking port 25 and they want you to use their relay server instead. Try telneting to your ISP's relay servers if it works then you will have to configure your mail server to use them as a smarthost.
Yes, my route is 192.168.1.254. And this is info of my ISP: Dirección de Internet: 189.176.121.90 Máscara de subred: 255.255.255.255 Puerta de enlace predeterminada: 200.38.193.226 Servidor principal de nombres de dominio: 200.23.242.177 Servidor secundario de nombres de dominio: 200.23.242.185 [root@local ~]# telnet 200.38.193.226 25 Trying 200.38.193.226... telnet: connect to address 200.38.193.226: No route to host telnet: Unable to connect to remote host: No route to host
I do not understand spanish but from what i see Puerta de enlace predeterminada is not an smtp server it is your default gateway You need to ask your ISP for the smtp relay server you are supposed to use especially if you are on DSL
