your email headers contain the entire authentication story

most people never read them

- SPF result
- DKIM signature verification
- DMARC evaluation
- ARC chain status
- receiving server identity

I built the email header analyzer to parse this automatically

get a structured breakdown:

- which checks passed
- which failed
- where the message was routed from
- and what each hop did to the authentication chain
