What we watch for

Hostnames in phishing feeds and certificate logs are matched on these brand tokens; feed target labels are matched on the aliases. Generated spellings (typos, lure words, look-alike characters, other top-level domains) are derived from the official domains and tokens and checked against feeds, certificate logs and DNS.

DKIM
Unknown (no known selector). DKIM use requires a known selector or message to assess; a published key alone cannot confirm signing.

Interpretation

  • p=quarantine: receivers are asked to treat failing mail as suspicious.
  • Relaxed DKIM alignment (default).
  • Relaxed SPF alignment (default).
  • -all: unlisted hosts fail SPF.
  • 9 DNS-querying terms (include, a, mx, ptr, exists, redirect), counted recursively; the limit is 10.
  • Static check of the published record: syntax, every referenced include/redirect record, the DNS-lookup count and a/mx/exists targets (resolved to count void lookups). It does not evaluate SPF for any particular sending host.
