mailauth turns raw email headers into a forensic report
A free, client-side analyzer that checks SPF, DKIM, DMARC, delivery paths, policy records, and spoofing risk from a pasted email header.
Field notes
The analyzer accepts a pasted raw email source and produces a combined view of authentication, routing, policy, and reputation signals. Its sample report assigns a B 88/100 grade, identifies a DMARC p=none policy, and shows separate DKIM alignment results alongside TLS versions and relay timings. The site also exposes a 26-term glossary and says its provider references are maintained as 16 dated sources, giving users a way to inspect the terminology and evidence behind its findings.
