Após o comprometimento do SMTPAUTH (nós trabalhamos para o servidor de restauração e nos saímos bem, já que não estamos mais nas listas negras desde semanas), notamos que os e-mails vindos do nosso servidor de e-mail são marcados como spam.
Eu li algum post sobre ( isso, por exemplo ) e instalei, configurei e executei o OpenDKIM (a assinatura DKIM está indo bem) e o SPF também. Eu também inverti dns / ptr disponível.
Quando eu abro o e-mail do google e uso "show original", tudo parece ser bom:
