How to Set Up DKIM for Emma?

October 11, 2023  |  2 min read

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.

Requirements for setting up Emma

You must publish the following 3 CNAME records on your domain’s DNS before configuring DKIM for Emma. They will resemble the examples below.

Host NameValues

Depending on the specifications of your DNS hosting provider, these CNAME records may differ somewhat and be linked to your email sending domain. Therefore, before publishing, please speak with your supplier or hosting company’s support staff.

Steps to Configure DKIM for Emma
