DomainKeys Identified Mail (DKIM) is a method for email senders to digitally sign email messages in a way that can be verified by email receivers. This allows receivers to verify that the message truly came from the sender, and has not been tampered with. DKIM is intended to address some of the flaws in the existing email system, such as spoofing, phishing, and message tampering.

Steps to Configure DKIM for Coremail

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

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

How to Get Your DKIM Public Key Available for Coremail

1. Sign in as the administrator to your DNS provider’s administration console.
2. Go to the DNS records section of each of your domains.
3. Depending on the type of DKIM record that has been provided to you, generate a TXT or CNAME record.
4. Copy and paste the hostname and value
5. Save your record’s modifications and wait 48–72 hours for your DNS to take effect.
