Microsoft article Q300171 (http://support.microsoft.com/default.aspx?scid=kb;en-us;q300171) says the domain that you are sending to may have Reverse Lookup enabled, and it is unable to perform a Domain Name System (DNS) lookup for your domain.

Reverse DNS lookup goes to the owner of the IP address ( probably your ISP) and checks to see that the name it resolves to corresponds to the sender name address. That way if I send some e-mail claiming to be techrepublic.com from IP address 1.2.3.4, the reverse lookup will show that techrepublic does not have that IP address and it will reject the mail.

www.dnsstuff.com indicates you (renaissance-kul.com) are in Malaysia and that reverse DNS for 203.115.229.20 is not configured
