Hello, everyone! I want help to understand a doubt about DNS configuration in cPanel. A professional has made some configurations of my first cPanel hosting server and I need understand if of currently DNS configuration is correct and why. I've requested that each location have your own IP: hostname(server), ns1 and ns2, but the currently configuration stay like this: Let's call my server server.abc.com in this example. Hostname: 1th IP >> pointed to the your reverse, server.abc.com NS1: 2th IP >> with reverse pointed to the same reverse of hostname: server.abc.com NS2: 3th IP >> with reverse pointed to the same reverse of hostname: server.abc.com ... Then when I do a ping to the ns1 or ns2... it resolve to the hostname of the server. I seen at WHM that I'm using PowerDNS. All server is work fine, but it is my main question: at past when I used other WHM of certain companies as reseller I seen each NS(1 and 2) resolve to your own IP adress, why on my case the professional has configured the NS1 and NS2 to resolve to the hostname? When questioned he told that is a IP routing related to sending emails. ... All work fine, but I want understand if is correct, or if is recommended, or what's recommended. Thank you!

  That is something you must ask him. The DNS configuration as it is now is ok, as long as you are sending emails from the 1st IP, if you send from 2nd or 3rd you get problems.

  Hello, If you're utilizing all three IP addresses to send mail, the reverse DNS should resolve to the hostname of the server mail is originating from. This is separate entirely from using those IP addresses for the Nameservers. If reverse DNS resolved back to the nameservers, mail would frequently end up in the spam box as the nameservers are not recognized as a valid host to send mail from as they're not listed in the header of the email as the source of the email.

  That is absolutely not true. Sending mail using any IP address present on the server, with the PTR record set to the hostname of the server is the best practice. The only exception to this is if you've customized the configuration to dedicate an IP for mail sending from one specific domain and set the mailhelo to reference that domain.
