Hi,Do you have proper PTR host record created for you domain.A PTR record (sometimes called a "host PTR record") is what lets someone do a "reverse" DNS lookup - that is, they have your IP address and want to know what your host/domain health.You can use below link for dns query:http://www.dnsstuff.com/http://www.checkdns.net/Also send us original header message so we can see complete NDR.Anil
