What the Kentucky numbers actually mean

DMARC posture. Kentucky's share of carrier domains with no enforced DMARC sits at 77.1% better than the national average by 3.0 points. Kentucky carriers adopt the enforced p=reject DMARC policy at a meaningfully higher rate than the national pool. At the protective end of the distribution, 9.7% of Kentucky domains are at p=reject — the only DMARC policy that actually instructs receivers to drop spoofed mail.

Microsoft 365 surface. Microsoft 365 mailflow adoption tracks the national distribution closely, so the 1,275 M365 carriers in Kentucky with DMARC disabled represent the same "paid-for-but-switched-off" pattern that drives the national headline. That share is 20.6% of all Kentucky carriers — a one-flag-flip remediation set that any regional MSP or in-house IT lead can clear in a single quarter.

Transport encryption. MTA-STS adoption sits at 4.1%, materially below the threshold a freight payment-redirect attacker would have to clear to be inconvenienced by transport-layer policy. DNSSEC adoption in Kentucky runs at 5.2% (vs 6.1% national) — meaningful for downstream DKIM and MTA-STS validation, but still a minority signal.

Risk-band shape. Kentucky's critical and high bands combine to 41.0% of state carriers — close to the national distribution, meaning remediation prioritization here should follow the same shape as the national program. The composite pain score blends SPF posture, DMARC enforcement, MTA-STS presence, and DNSSEC — so a carrier clusters in the critical band only when several controls fail together. Remediation that flips DMARC to enforcement plus turns on MTA-STS typically moves a carrier two bands down in one quarter.

What this means for buyers and shippers. If you are dispatching freight, settling broker payments, or receiving rate confirmations from Kentucky-based carriers, the operational exposure is the 77.1%of domains that cannot stop a stranger from sending email in the carrier's name. Payment-redirect and load-redirect fraud rides on exactly that gap. Verifying a counterparty's DMARC posture before a first wire — a 30-second DNS lookup — is the cheapest control in the freight stack.
