Posted by timmyd, 04-14-2010, 02:08 AM Hi all, i got trouble with MX PTR searching through many forums they say its usually a wrong setting with the provider. this is what i got: error: ----------------- Reverse MX A records (PTR) ERROR: No reverse DNS (PTR) entries. The problem MX records are: 111.222.33.44.in-addr.arpa -> no reverse (PTR) detected You should contact your ISP and ask him to add a PTR record for your ips email wont be delivered. ----------------- So i contact them and they say it all is ok. than it should be a wrong setting on my server, i presume... steps / configs i got are: resolv.conf search ns1.server.net nameserver 1.2.3.4 #some ip from the provider, other than mine nameserver 2.2.3.4 #some ip from the provider, other than mine /etc/named.conf zone "111.222.33.44.in-addr.arpa" { type master; file "/var/named/111.222.33.44.in-addr.arpa"; allow-transfer { 222.222.33.44; }; }; /var/named/111.222.33.44.in-addr.arpa $TTL 38400 111.222.33.44.in-addr.arpa. IN SOA ns1.server.net. root.localhost. ( 2010041301; 28800; 7200; 604800; 86400 ); 111.222.33.44.in-addr.arpa. IN NS ns1.server.net. 222.222.33.44.in-addr.arpa. IN NS ns2.server.net. 111.222.33.44.in-addr.arpa. IN PTR ns1.server.net. 111.222.33.44.in-addr.arpa. IN PTR mail.server.net. I hope someone can help me with this. OS Centos5.x Bind9.x dns
Posted by xerophyte, 04-14-2010, 03:00 AM from your server can you do this dig -x ip_address if you return a hostname you are good, since you don't host reverse dns zone on your nameserver, you don't have to configure the bind for it . hope that helps
Posted by madaboutlinux, 04-15-2010, 04:59 AM If you are looking to set a reverse PTR for the server IP, then it's only your host OR the Data Center that can do it for you. You can verify the rPTR at http://iptools.com/dnstools.php?tool=rdns&user_data= Specify the main IP of the server in the available text box and click GO. If it doesn't provide you any result, forward the same URL to your hosting company and ask them to check.
