1. display doesnt work properly. i can post my X config file.What exactly isn't working? Any errors in your logs?


2. i can ping the IP address but i can not remote in or telnet it from anyother windows machine or connect to mail server. (postfix)Most likely a firewall problem. What's the output of iptables -L?
3. i can send email out but can not receive email .

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 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?
