    hello

    i have installed on centos5 postfix with this howto http://www.howtoforge.com/perfect_setup_centos5.0_p5?

    now i use squirelmail to test it , and i can receive email ,but i can't send .
    my firewall and selinux are disable , the router is ok.

    in my var/log/maillog i have this :

    Code:
    Apr 25 10:18:24 mydomain postfix/smtp[8255]: connect to mx6.libero.it[212.52.82.7]: Connection timed out (port 25)

    Do you host your mail server at home or in an office, or is it in a data center?
    If you host it yourself: Please ask your ISP if they block port 25.

    You can use only the ports that the smtp.wanadoo.nl offers.
    I've just tried to telnet that server from my own server (in a data center), and also can't connect.
    Are you sure this is the correct server? If so, I'd contact the Wanadoo support and ask what's wrong.
