I have named running on port 53 on my server so it should be correct. The reason the script is saying it is not open is because it runs a check out to see if port 53 is accessible on the public internet and if it is not gives you that message. Also, when I check to see if I can get any response for your domain out using nslookup tools I also don’t get a response.
I use ESXi for my virtualization platform, but they all work similar. Lets blow away both with the below:
apt-get remove bind9
apt-get remove nsd*
That should get rid of both from the server. Then check to see if anything is sitting on port 53 before starting the reinstall. I love the installer of MiaB as it is smart enough to reinstall missing services.

@miabatf2f10 please contact your ISP / VPS provider to confirm they are not blocking the ports. (some VPS providers will auto block these ports if you send or receive too much mail as an example or if you violate a ToS somewhere)
Also confirm sudo is working as it should not complain about process ownership when running netstat with sudo.
I am getting “220 box.f2f10.com ESMTP Hi, I’m a Mail-in-a-Box (Ubuntu/Postfix; see https://mailinabox.email/)” when accessing ports 25 and 587 on that IP.

I tried to hide my IP , but obviously I disclosed it already…
