That leaves freight operators open to email impersonation, payment-redirect fraud, and cargo theft via phishing. Edition: 2026-Q2 State rank: #44 Carriers: 1,737 Domains: 1,280 By [Stefan Efros](https://www.linkedin.com/in/stefanefros-cyberdefense/), CEO & Founder, EFROS Updated · May 19, 2026 No enforced DMARC 79.1% national: 80.1% p=reject 8.4% national: 7.5% Microsoft 365 34.9% national: 38.1% M365 + no DMARC (carriers) 349 national: 92,822 MTA-STS 4.4% national: 3.3% DNSSEC 6.1% national: 6.1% Dead domains 67 of 1,280 scanned Total carriers 1,737 67 with dead domain ## Risk bands — New Mexico carriers Carrier counts by risk band (composite email-security pain score). Critical = score 70+; Minimal = score <15. | Risk band | Score range | Carriers | Domains | | --- | --- | --- | --- | | Critical | score 70+ | 133 | 107 | | High | score 50–69 | 477 | 426 | | Medium | score 30–49 | 775 | 492 | | Low | score 15–29 | 269 | 175 | | Minimal | score ## New Mexico vs. national average No enforced DMARC 79.1% vs 80.1% national p=reject adoption 8.4% vs 7.5% national MTA-STS 4.4% vs 3.3% national DNSSEC 6.1% vs 6.1% national ## What the New Mexico numbers actually mean **DMARC posture.** New Mexico's share of carrier domains with no enforced DMARC sits at **79.1%**, within 1.0 points of the national average. enforced p=reject DMARC adoption is roughly in line with the national pool: most New Mexico domains either have no DMARC at all or are stuck at the monitor-only p=none policy. At the protective end of the distribution, 8.4% of New Mexico domains are at p=reject, the only DMARC policy that actually instructs receivers to drop spoofed mail. **Microsoft 365 surface.** Microsoft 365 mailflow adoption sits below the national rate, which shifts the remediation surface toward self-hosted and Google Workspace estates where DMARC has to be configured at the DNS layer rather than flipped on in a tenant policy. That share is **20.1%** of all New Mexico 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 (the encrypted-transport policy that prevents DNS-downgrade interception) runs above the national rate, but the absolute floor is still under 9%, well short of where freight payment flows should sit. DNSSEC adoption in New Mexico runs at **6.1%** (vs 6.1% national), which matters for downstream DKIM and MTA-STS validation but is still a minority signal. **Risk-band shape.** New Mexico's critical-band share is 7.7% versus 8.4% nationally, with the pressure shifting into the high band (27.5% of state carriers) where one or two control gaps still leave room for impersonation. 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 New Mexico-based carriers, the operational exposure is the 79.1%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. ## Compare New Mexico with other states States closest in carrier-count rank to New Mexico. Each is scored on the same DNS-derived control set, so the comparison is apples-to-apples.
