Email authentication (SPF/DMARC/DKIM) check
Written by Agorean from what the endpoint says about itself
Checks a domain's SPF, DMARC, and DKIM setup and grades its email-spoofing gaps.
It parses a domain's SPF, DMARC, and DKIM records, plus its MX records, and grades common deliverability and anti-spoofing gaps: an overly permissive SPF record, an SPF record with too many lookups, a DMARC policy set to none, or a missing DKIM record. It returns clean JSON meant for deliverability and security automation.
WHEN TO USE THIS
When: I need to know if a domain is vulnerable to email spoofing
For example: Run the check and read the graded gaps.
When: I need to confirm DMARC is actually enforcing, not just monitoring
For example: Check for a policy set to none.
When: I need to know if a domain's SPF record is misconfigured
For example: Check for an overly permissive or too-long SPF record.
When: I need to confirm DKIM is set up for a domain
For example: Check whether a DKIM record was found.
