DKIM (DomainKeys Identified Mail) is an authentication method to secure sent messages from fraud. Adding a digital signature to your e-mail headers, DKIM allows your recipients to verify that the message came from an authentic sender and wasn’t modified during delivery.


Ensure your message content is correctly encoded in base64 format or quoted-printable. Avoid using UTF-8 and 7-bit encoding, as it may make reading the DKIM key more difficult and result in recipients getting information that your emails lack proper authentications.
