Eles podem parecer t\u00e9cnicos, mas a ideia \u00e9 simples. Este guia explica cada um deles em linguagem acess\u00edvel.<\/p>\n<h2>SPF: quem tem permiss\u00e3o para enviar<\/h2>\n<p>Um registro SPF lista os servidores de e-mail autorizados a enviar mensagens em nome do seu dom\u00ednio. Quando uma mensagem chega, o servidor destinat\u00e1rio verifica se ela veio de uma fonte aprovada. Um dom\u00ednio deve ter exatamente um registro SPF.<\/p>\n<h2>DKIM: prova de que a mensagem n\u00e3o foi adulterada<\/h2>\n<p>O DKIM adiciona uma assinatura digital \u00e0s suas mensagens enviadas. O servidor de destino verifica essa assinatura em rela\u00e7\u00e3o a uma chave p\u00fablica no seu DNS para confirmar que a mensagem realmente veio do seu dom\u00ednio e n\u00e3o foi alterada durante o tr\u00e2nsito.<\/p>\n<h2>DMARC: o que fazer em caso de falhas<\/h2>\n<p>O DMARC integra o SPF e o DKIM e indica aos servidores receptores o que fazer com as mensagens que n\u00e3o passam na verifica\u00e7\u00e3o \u2014 desde apenas monitorar at\u00e9 encaminhar para a pasta de spam ou rejeitar. Ele tamb\u00e9m envia relat\u00f3rios sobre quem est\u00e1 enviando mensagens em nome do seu dom\u00ednio.<\/p>\n<h2>Como eles trabalham juntos<\/h2>\n<ul>\n<li><strong>FPS<\/strong> indica quais servidores podem enviar.<\/li>\n<li><strong>DKIM<\/strong> comprova que a mensagem \u00e9 aut\u00eantica.<\/li>\n<li><strong>DMARC<\/strong> define a pol\u00edtica e proporciona visibilidade.<\/li>\n<\/ul>\n<h2>Como configur\u00e1-los<\/h2>\n<p>Cada um deles \u00e9 um registro DNS que voc\u00ea adiciona ao seu dom\u00ednio, usando os valores exatos fornecidos pelo seu provedor de e-mail. Inicie o DMARC no modo de monitoramento, confirme se suas mensagens leg\u00edtimas s\u00e3o aprovadas e, em seguida, torne a pol\u00edtica mais restritiva.<\/p>\n<h2>Precisa de ajuda?<\/h2>\n<p>Nossa equipe de suporte pode ajud\u00e1-lo a criar e verificar esses registros.
