This subdomain hosts the SMTP MTA-STS policy file for audithunt.com, per
RFC 8461. It is a machine-readable
file fetched by mail servers when they send mail to @audithunt.com, to verify
which MX hosts are valid and require TLS.
The policy is at /.well-known/mta-sts.txt.
For everything else — audit reports, contact, etc — visit audithunt.com.
