DKIM works by adding a digital signature to outgoing email messages. This signature can be verified by the receiving email server, which can then determine whether or not the message has been tampered with during transit. In order for DKIM to work, the sending email server must generate a cryptographic key pair, which consists of a private key and a public key. The private key is used to sign outgoing email messages, while the public key is published in the Domain Name System (DNS). When an email message is signed with DKIM, the signature is added as a header to the message. The receiving email server can then use the public key to verify the signature and confirm that the message has not been altered. 

Steps to Configure DKIM for ontraport

To obtain your DKIM keys and enable DKIM authentication for your domains, contact ontraport support team. You will receive a DKIM key pair from ontraport support that will include:

1. A DKIM public key, which should be published in your public DNS.
2. A DKIM private key: used by ontraport to sign your outgoing emails

The DKIM key pair can also be created using our free DKIM record generator tool if you are sending emails from your own servers as opposed to ontraport.
