DNS & Email Security Checker

Inspects core DNS and email-related records for a domain:

• A / AAAA
• NS
• MX
• SPF (TXT v=spf1)
• DMARC (_dmarc.domain)
• DKIM (common selectors)

Useful for quickly understanding how mail delivery and protection are configured.

For request format, parameters, and examples, see the Endpoint page in this module.
