Strange problem with a machine using HestiaCP

I have one strange problem with one machine using a HestiaCP.

I send a mail from roundcube… and after 1 day I received mail like this:

> This message was created automatically by mail delivery software.

And I testing this:

Server:  Hitronhub.home

*** Hitronhub.home can't find Non-existent domain

The reason: Client host rejected: cannot find your reverse hostname

So… What I can do for solved this problem? Please give me a advice for this problem :slight_smile:

Using Debian 11, and last update HestiaCP ( Hestia Control Panel has been updated to v1.5.15.)

   Static hostname:
         Icon name: computer-container
           Chassis: container
        Machine ID: e4282835bf2d4444903131c41a2c041a
           Boot ID: 10a6425869d2472599ade81ec28d9fcb
    Virtualization: lxc
  Operating System: Debian GNU/Linux 11 (bullseye)
            Kernel: Linux 5.13.19-6-pve
      Architecture: x86-64

DNS Checking its OK , but PTR is not ok… so how I can add PTR record in HestiaCP?

PTR Checking:
Error: Invalid IP Address.

You need to contact your provider to alter your PTR record how ever assume it is it an home connection?

Domain (godaddy) or Hosting provider ?

Hosting provider

As far as I know (I read here: domain name system - How to setup PTR (Reverse DNS) at Godaddy DNS manager - Server Fault @Jan Mandel) PTR record is created by the hosting in this case I use VPS + HestiaCP) and I am the Hosting Provider. How can I add this PTR record through the hestia panel?

If you are the owner of the ip space? Yes

If now ask your internet provider

Sounds like your internet router…

Solved. I using leaseweb provider (dedicated with vps servers) … and theare I found option like “Reverse DNS”.

I added a my Static hostname output from my hostnamectl in server terminal.

Now the result is like this:

Server:  Hitronhub.home
