Check DKIM record of your domain!

DomainKeys Identified Mail (DKIM) is an anti-tamper protocol that ensures that your mail remains secure in transit. DKIM uses digital signatures to check that the email was sent by a specific domain. Furthermore, it confirms whether the specified domain truly authorized the sending of the email. DKIM can also be considered an extension of SPF.

DKIM’s email validation process consists of two actions. The first action is taken when the sending server sends a DKIM signed email. The second action is taken when the recipient server checks the DKIM signature on the incoming email. The entire process is made possible by a pair of private and public keys. The private key must be kept confidential and is saved either on the sender’s own server or with their ESP. The public key, on the other hand, is added to the DNS records of the sender’s domain and broadcasted to the world to help verify all emails.
