Le champs SPF est un champs important pour la délivrabilité de vos e-mails. Mal configuré, absent, cela peut vous occasionner des rejets de réception des e-mails que vous envoyez à vos correspondants. Un autre champs TXT important est la signature DKIM qui jour également, énormément, en faveur de la délivrabilité des vos e-mails
Plus généralement, le SPF, ou Sender Policy Framework, est un système de vérification conçu pour empêcher l'usurpation d'adresse électronique en validant l'expéditeur d'un e-mail. Lorsqu'un domaine met en place un enregistrement SPF, il spécifie quels serveurs de messagerie sont autorisés à envoyer des e-mails. Lorsqu'un e-mail est reçu, le serveur de réception peut vérifier cet enregistrement pour s'assurer que l'e-mail provient d'un serveur des serveurs autorisés. Si ce n'est pas le cas, il peut être marqué comme suspect ou rejeté, ce qui aide à réduire le spam et le phishing en vérifiant que les e-mails proviennent bien de la source autorisés.
