is your SMTPd listening on your public IP? |

I think yes because this is the telnet result to my public ip: $ telnet 10.300.432.403 25 Trying 10.300.432.403... Connected to 10.300.432.403. Escape character is '^]'. 220 mail.example.com ESMTP Postfix |

You might have better luck posting real information; for now, without trying it from here, all I can come up with is "huh, that's weird." |

From outside your Linode? It'll still use lo if you do it from your Linode. |

The traffic may flow over "lo" but the IP addresses used would be the public ones and so would be a sufficient test to determine that the daemon is bound to the public address. It's not enough to test firewall rules. |

thanks for the replies, but i didn't get any idea what to do, i just test my mail server and i can send emails from my mail server to the net but can't get the emails from the net? can it be also my isp problem that blocks the port 25? |
