What this means

  • • Politique p=none : surveillance seule, aucun message non authentifié n'est bloqué.
  • • SPF se termine par ~all (softfail) : acceptable en phase d’observation, viser -all à terme.
  • • Aucune clé DKIM trouvée sur les sélecteurs courants (le domaine peut utiliser des sélecteurs non standards).
