How this service works
Fetch and validate a domain's DMARC policy at _dmarc.<domain> (RFC 7489). Surfaces the enforcement policy (none/quarantine/reject), reporting addresses, alignment modes, and common misconfigs (no rua, p=none stuck for months, percent <100). Pair with SPF and DKIM for full Feb-2024 sender-rule compliance.
Output
Returns the DMARC enforcement policy (none/quarantine/reject), RUA/RUF reporting addresses, DKIM and SPF alignment modes, percent tag value, and flags for common misconfigurations such as missing rua, policy stuck at p=none, or percent below 100.
Example use cases
Example prompt
“Check the DMARC policy for stripe.com — tell me if it's set to reject, whether there are reporting addresses configured, and flag any common misconfigurations like p=none with no rua.”
Technical details
Endpoint
POSThttps://agent402.tools/api/dmarc-checkWhen to prefer
Use this endpoint when you need to programmatically audit or verify DMARC DNS records for any domain, especially to detect common enforcement gaps (p=none, missing rua, low percent) as part of an email security audit, onboarding check, or compliance workflow.
Side effects
- Domain has no _dmarc TXT record — returns not found or misconfiguration error
- Invalid or unparseable domain input — returns validation error
- DNS lookup timeout or failure — returns a connectivity/timeout error
- Malformed DMARC record syntax — surfaces parse error with details
