How to add MX record to DNS Windows server 2019?

Question

Domain Name System

I created a DNS zone tanagre.su based on Windows Server 2019 and now I want to raise the Zimbra mail server on Centos 7. The machine on Centos 7 is entered into the domain. Added an mx record to DNS Manager Windows Server indicating the name of the Centos 7 host on which I am going to raise the mailer. But when checking mx records with the host -t mx tanagre.su command, the error "tanagre.su has no MX record" occurs. How do I create an MX record in DNS Manager for Centos 7 to see it?

Answer 1

An MX record for the main domain must be created for the domain itself, without specifying anything in the "Host" field.
You have now created an MX record for the vm-mail.tanagre.su domain.

Answer 2

In the DNS zone, the MX record points to the root of the domain, while in yours it points to a specific host.
This is how it should be:

I'm sure if you do host -t mx vm-mail.tanagre.su you will see everything :)
