Quick Answer
An email authentication protocol that lets receiving servers verify that an email was sent by the domain it claims to be from.
DKIM adds a digital signature to every email header using public-key cryptography. The sending server signs with a private key; the receiving server verifies using a public key published in DNS (TXT record). DKIM prevents email spoofing and improves deliverability. MisarMail automatically configures DKIM for your sending domains.
