Setup rDNS on a standalone physical server
« on: July 21, 2020, 03:28:16 PM »
I have installed CWP and everything went quite well until I found out that all my emails are landing in the spam folder of the recipient, I surely need to add rDNS record, so I started looking up for help online on how to setup rDNS in CWP, unfortunately everyone's talking about asking your hosting provider to set it up for you.

Here's my scenario, I purchased a physical server, subscribed for bandwidth and static IP and installed my server by enabling DMZ host, everything is working fine except for the emails. I have tried a thousand ways but nothing worked. When I go to "List DNS Zones", I click on "Check Records" here's the result I get;

"rDNS/PTR record check: SUCCESS
rDNS/PTR = ; <<>> DiG 9.11.4-P2-RedHat-9.11.4-16.P2.el7_8.6 <<>> -x +short @8.8.8.8;; global options: +cmd;; Got answer:;; ->>HEADER<<- opcode: QUERY, status: NXDOMAIN, id: 12280;; flags: qr rd ra ad; QUERY: 1, ANSWER: 0, AUTHORITY: 1, ADDITIONAL: 1;; OPT PSEUDOSECTION:; EDNS: version: 0, flags:; udp: 512;; QUESTION SECTION:;+short.in-addr.arpa. IN PTR;; AUTHORITY SECTION:in-addr.arpa. 2508 IN SOA b.in-addr-servers.arpa. nstld.iana.org. 2020071869 1800 900 604800 3600;; Query time: 174 msec;; SERVER: 8.8.8.8#53(8.8.8.8);; WHEN: Sun Jul 19 23:22:51 PKT 2020;; MSG SIZE rcvd: 116
rDNS A record = [Check SenderBase] [Check RBL]

Checking with google if domain is hosted on this server: FAILED"

Google check fails but it says that rDNS/PTR is successful.

Now when I go to "Change Hostname"; here's what I see;

"Your Hostname is: panel.domain.tld and it resolves to IP: 182.180.xx.xxx [Check Black List] [Check CWP SSL] [Check WebServers SSL]
rDNS/PTR = FAILED, check with your hosting provider! FAILED [Check SenderBase]"

Just to tell you that I have installed it on vmware!
I don't understand where am I going wrong. Help would be much appreciated.

Like too many people: the rules/advice don't apply to them!
"unfortunately everyone's talking about asking your hosting provider to set it up for you."

You need to read a bit more?
Try asking your Google about NXDOMAIN?
