Original GitHub issue: https://github.com/modoboa/modoboa/issues/3399

Impacted versions

OS Type: Ubuntu
OS Version: 24.04
Database Type: MySQL
Database version: X.y
Modoboa: 2.3.4
Installer used: No
Webserver: Nginx/Apache

Steps to reproduce

Configure a custom dns server in the Administration Panel and manually execute an MX check.

Current behavior

The get_authoritative_server function does not actually uses the configured resolver but the default one:
github.com/modoboa/modoboa@2cb6ccebfa/modoboa/admin/lib.py (L201)

In my case it results in SPF and DKIM checks wrongly failing, because I have different DNS views for my domains, and the SPF and DKIM records are only available on views that are used when resolving from an external DNS server.

Expected behavior

The function should use the resolver returned by get_dns_resolver(). In practice the line mentioned above should be changed to:
answers = resolver.resolve(dnsname, "NS")
