Hi I have setup a postfix server which sends mail properly to yahoo and gmail but not ntlworld. In the logs I get reject in response to data command. So whats the issue there?

you are probably on a dynamic ip. your isp should have an upstream smtp server which you can legitmately relay through. i used to do this when i was on ntl actually, using smtp.ntl.com or something... bt uses smtp.bt.net. google for it and you'll find the one for your own ISP.
