Hi JD, Thanks for your response,
i am sure, it is some problem where you tried to resolve from. There is PTR for the host and it exists in my own authoritative DNS server. i tried to dig using through google DNS as well. Result shows that PTR is there. [root@mailer mailer]# dig @8.8.8.8 -x 41.211.25.193 ; <<>> DiG 9.7.3-P3-RedHat-9.7.3-8.P3.el6_2.2 <<>> @8.8.8.8 -x 41.211.25.193 ; (1 server found) ;; global options: +cmd ;; Got answer: ;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 48506 ;; flags: qr rd ra; QUERY: 1, ANSWER: 1, AUTHORITY: 0, ADDITIONAL: 0 ;; QUESTION SECTION: ;193.25.211.41.in-addr.arpa.
