Original GitHub issue: https://github.com/modoboa/modoboa/issues/2246

Impacted versions

OS Type: Debian
OS Version: 10
Database Type: MySQL
Database version: 10.3.27-MariaDB-0+deb10u1
Modoboa: 1.17.0
installer used: Yes
Webserver: Nginx
python --version: Python 3.7.3

Steps to reproduce

Do a default install of Modoboa on Debian 10.
[Using "mailsrv" instead of "mail" as the mail server's subdomain. Using Let's Encrypt.]
Define valid MX servers in Modoboa: mailsrv.MY-DOMAIN-HERE.de mailin.MY-DOMAIN-HERE.de
Set up a first mail domain for testing (modoboa.MY-DOMAIN-HERE.de)

Current behavior

DNS Status stuck at checks pending (Erwarte Prüfungen).
Throws error and generates a mail every 30 mins. containing this:

Had this issue too. Discovered you have to set your Valid MXs to IP addresses instead of hostnames. You can do this in the dashboard under Modoboa > Parameters > Administration > Valid MXs

See #1664
