MX exact record and forbidden host

71-dns-mx-exact.yaml

DNS

What this example does

DNS infrastructure verification: MX exact record and forbidden host. It helps detect resolution, delegation or published-record problems.

Checks and behavior

  • Queries DNS records or resolver behavior ([{'type': 'MX', 'equals': ['10 mail.example.com.'], 'not_contains': ['old-mail'], 'min_count': 1, 'max_count': 3}]).
  • Formats results for nagios output.

Adapt example domains, addresses, credentials and thresholds to your environment before use.
