SPF lookups 7/10

SPF / DKIM / DMARC above reflect the last 4 emails we've observed. DMARC policy is read live from DNS.

Authentication

DMARC reports sent to dmarcinput.com. Policy p=none is monitor-only — receivers won't act on spoofing yet.

DKIM alignment: all 12 observed emails sign with a domain aligned with raybrehm.com (raybrehm.com). DKIM authenticates the visible From — supports DMARC directly.

Transport & deliverability

TLS: 0% TLS 1.3, 100% TLS 1.2 (across 6 sends).

Delivery: fast — 100% of emails in the last 7 days arrive in under 10 seconds (across 2 sends).
