Re: BIND 9.9 cannot resolve PTR record but +trace can

. The operator of this reverse zone (EST Bilisim) should update the delegation of 131.161.213.in-addr.arpa (in the RIPE Database) and use the proper name servers names in there. If you know someone there, please inform them. Regards, Anand On 11/04/2018 15:23, Aras Yorgancı wrote: Thanks for reply

Hi, Our BIND 9.9 DNS servers cannot resolve PTR record of a mx server. So We cannot established e-mail communication. [root@localhost ~]# dig @127.0.0.1 -x 213.161.131.25 ; <<>> DiG 9.9.4-RedHat-9.9.4-51.el7_4.2 <<>> @127.0.0.1 -x 213.161.131.25 ; (1 server found) ;; global options: +cmd ;;
