Email Authentications prevent the email from going into the spam
folder of recipients. cPanel uses DKIM and SPF to reduce the amount of
spam mails. Enabling these features will prevent spammers from forging
messages that claims to be coming from your domain.
When DKIM is enabled, the sender signs the email with a digital signature using a private key. When the email approaches the recipient, it retrieves the public key of its sender and checks if the signature matches. If the signature is invalid, then message is treated as a spam message.
