Bonjour j'ai reçu récemment un spam sur mon site internet je me suis donc intéresser à ça provenance quelle a été mon étonnement en voyant que le Message ID de l'en-tête du mail contenait mon nom de domaine, cela veut donc dire si je ne me trompe pas que le message a été envoyer ou générer par mon serveur ? Si oui pensez vous qu'il s'agisse d'un problème de sécurité lié à mon site (je précise qu'il n'ai pas encore lancé donc difficilement trouvable) ? Ou un problème lié à la configuration de ma boîte mail ?

Je vous met ci-dessous l'en tête du mail en ayant au préalable anonymiser les données (du moins je l'espère) :
