SPF policy · Norway companies
What share of Norway companies have no enforcing SPF record (absent, ~all soft-fail, or +all)?
44.49% of Norway companies (95% CI 41.35–47.68%), measured across 944 companies on 2026-08-17.
Measured every Monday since 2026-08-01 — 3 observations to date. Last measured 2026-08-17.
How this is measured
Tier 0. TXT at the apex; find v=spf1, read the all qualifier, count direct lookups. Denominator: has_mx.
Passive measurement: a single DNS lookup, TLS handshake, or homepage GET per domain. Aggregate-only; no individual company is named. 95% Wilson confidence intervals. Population: national company registries (Companies House, Brreg, SIRENE), sampled by size band and resolved to email-active domains. Parked domains excluded. Snapshot: brreg-norway-per600-seed20260730.

Why it matters
~all is the SPF equivalent of p=none and overwhelmingly the most common configuration — it asks receivers to accept-but-mark, so spoofed mail still arrives. +all authorises the entire internet to send as you. Exceeding the 10-lookup limit makes the record fail permanently and silently, because receivers abort evaluation.
Limits of this measurement
The lookup count is non-recursive (it does not expand include:), so it is a lower bound and catches only egregiously over-limit records.
