DKIM<\/h1>\n

DKIM, qui signifie\u00a0<\/span>Domain Keys Identified Mail<\/span><\/a>, est un\u00a0<\/span>protocole d’authentification des emails<\/span><\/a> qui utilise des signatures cryptographiques pour v\u00e9rifier que le contenu d’un message <\/span>n’a pas<\/span> \u00e9t\u00e9 alt\u00e9r\u00e9 pendant le transit. Lorsqu’un message est envoy\u00e9, le serveur d’envoi ajoute un en-t\u00eate de signature DKIM qui inclut un hachage chiffr\u00e9 du corps du message et de certains en-t\u00eates. Les serveurs de r\u00e9ception utilisent la cl\u00e9 publique publi\u00e9e dans le DNS de l’exp\u00e9diteur pour d\u00e9chiffrer la signature et confirmer que le message est intact et qu’il a \u00e9t\u00e9 autoris\u00e9 par le domaine d’envoi.\u00a0<\/span>\u00a0<\/span><\/p>\n

DKIM aide \u00e0 prot\u00e9ger les destinataires contre l’usurpation et la falsification, et joue un r\u00f4le cl\u00e9 dans la d\u00e9termination de la r\u00e9putation d’exp\u00e9diteur lorsqu’il est utilis\u00e9 avec SPF et DMARC.\u00a0<\/span>\u00a0<\/span><\/p>\n

Configurez des protocoles d’authentification des emails tels que\u00a0<\/span>le protocole SPF<\/span><\/a>,<\/span> DKIM, <\/span>DMARC<\/span>,<\/span><\/a>\u00a0et\u00a0<\/span>BIMI<\/span><\/a> <\/span>p<\/span>our prot\u00e9ger votre marque. Ces protocoles aident les fournisseurs de bo\u00eetes de r\u00e9<\/span>ception \u00e0 <\/span>v<\/span>alider<\/span> que vos messages sont authentiques, inalt\u00e9r\u00e9s et align\u00e9s avec votre domaine, renfor\u00e7ant ainsi votre cr\u00e9dibilit\u00e9.<\/span>\u00a0<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"
