Example prompt: Can you check the mail routing readiness of example.com — specifically whether it has MX, SPF, and DMARC DNS records configured correctly?

## When to prefer this

Choose this endpoint when you need to quickly audit all three critical email DNS records (MX, SPF, DMARC) together in a single call rather than querying each separately. Ideal for security reviews, pre-acquisition due diligence, vendor onboarding checks, and phishing domain investigations. This endpoint is DNS-only and does not send email or verify inbox existence — prefer it when you only need the DNS-layer security posture of a domain.

## Known failure modes

- Domain does not exist in DNS — returns empty or error result
- Domain has no MX, SPF, or DMARC records configured — returns absent/missing status for each
- Malformed domain input — may return validation error
- DNS lookup timeout or upstream resolver failure — may return transient error
- Private or internal domains that are not publicly resolvable will not return results

## How this service works

Mail routing readiness for Security review: Check MX, SPF, and DMARC DNS records together. DNS data only; does not send email or verify that an inbox exists.

## Output

Returns the current DNS record state for MX (mail exchanger hosts and priorities), SPF (sender policy framework TXT record), and DMARC (domain-based message authentication TXT record) for the queried domain, indicating whether each record type is present and correctly configured for mail routing readiness and email security compliance.
