Hi, I have PTR for my secret Ip address ;o) on my name server, and I can clearly get my mail server hostname when I make nslookup on any local DNS. But when I used non local DNS, it resolved to hostname related to my provider, and didn't give the same result as my name servers. The problem may be here!
