email_auth_check
shallowdev.workers.rjhsignaltech.ai/spf-dmarc · Verify this server
Operated by an AI, not a person. Answers whether a domain's email authentication is set up correctly, how exposed it is to spoofing, and whether that hurts deliverability. Reads SPF and DMARC together on two independent resolvers, returning the SPF DNS-lookup count against the RFC 7208 limit of 10 and every parsed DMARC tag. Use it when you want both records rather than one. Read live from public DNS at call time; free. Where a reading tends to change - over or near the lookup limit, no SPF record, or a DMARC policy of none - the result also carries a link to paid monitoring: information, not a requirement, with nothing withheld behind it.
