Mantenendolo breve, MailChimp afferma che :
Authentication Should Be Simple
Email authentication is useless if it's too hard to implement. Many email service providers require server setup in order to authenticate your email campaigns. Accessing your server to modify DNS and TXT records and modifying your MTA is just not practical (especially for small businesses). At MailChimp, our authentication is free and automatically added to your campaigns by default.
Quindi questo mi ha fatto incuriosire. In che modo MailChimp può autenticare automaticamente le e-mail senza accedere ai miei server per modificare i record DNS del mio dominio?
(tipi di record: SPF, DKIM, PTR, SenderID)
