    Maybe you are blocked in black list.
    Check the IP address is http://www.dnsstuff.com and verify that your server is not opened for relay:

      Hi ,

      Thanks for your great Help !! I have checked it from the given link , but my server is not an open relay ...but when i check my ip for the spam database ..it shows this worning ..

      x.x.x.x has no reverse DNS entry; some mail servers may not accept your mail.

      What does this means exactly ...i have not configured the DNS service in my server..and not created forward look up or reverse look up zone ...only the thing is i have added address primary and secondary DNS in my Ethernet card as per the guidance of the ISP ..

      Please help me to solve this...

        Ask your ISP to verify / create a PTR DNS record to your MX record (this is not a local configuration at your domain) - there are some sites that check this record in order to validate the sender somain / IP.
