Como implantar com meu diagrama DKIM em todos os e-mails no servidor original e no servidor de retransmissão?

    

Answer 1

Você pode configurar o DKIM no servidor de correio de saída, se você controlá-lo. Depende exatamente de qual servidor de e-mail você está usando. Com o postfix, você pode configurar um medidor opendkim para injetar o cabeçalho nos e-mails enviados.
