    What exactly isn't working? Any errors in your logs?


    Most likely a firewall problem. What's the output of
    Code:
    iptables -L
    ?
    Any errors in your mail log? Does the MX record of the domain you're sending to point to your server? You can check that with
    Code:
    dig mx yourdomain.com

    Is 194.54.8.248 the correct IP address?
    Is your server in a local network? Does your ISP block port 25?
