DKIM adds a digital signature to your outgoing emails, helping you authenticate your emails. Unfortunately, not much information is publicly available about how Nine handles DKIM authentication for domains. We recommend you get in touch with the Nine support team to learn more about the same.
Publishing your DKIM public key
After you get your public key:
- Login to your DNS provider’s management console as the admin
- Navigate to the DNS records section
- Create a TXT or CNAME record depending on the type of DKIM record provided to you
- Copy and paste the hostname and value
- Save changes to your record and wait for 48-72 hours for your DNS to process these changes
