How to Set Up DKIM for IRIS CRM?

October 11, 2023  |  < 1 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. 

Steps to Configure DKIM for IRIS CRM

  • Sign in as the administrator to your DNS provider’s administration console.
  • Go to the DNS records section.
  • In your DNS, create two CNAME records. These are what they are:

Host: iris._domainkey
Points to:
TTL: 1 hour / 3600

Host: iris1._domainkey
Points to:
TTL: 1 hour / 3600

  • Save any changes you make to your records, then give your DNS 48 to 72 hours to take effect:
