SPF / DKIM / DMARC above reflect the last 2 emails we've observed. DMARC policy is read live from DNS.

Authentication

DMARC reports sent to everest.email. Policy p=reject means receivers actively block or quarantine spoofed mail.

SPF alignment: all 2 observed emails use a return-path aligned with one.fan (bounce.e.one.fan). SPF authenticates the visible From — supports DMARC directly.

DKIM alignment: all 2 observed emails sign with a domain aligned with one.fan (e.one.fan). DKIM authenticates the visible From — supports DMARC directly.
