DKIM helps to verify the sender of an email and check if any alterations are made to the email in transit. Setting up DKIM record for your domain will help prevent your emails from going to spam at the recipient end. The below article will help you understand the importance of DKIM and how you can set it up for your Titan domain.

What is DKIM record?

DKIM is an email security standard designed to make sure that an email is not altered in transit between the sender and recipient server.

It uses an approach called “public-key cryptography” to verify that an email message was sent from an authorized mail server, and makes sure that the email delivered is an authentic one and no alterations were made to it in transit.

How does DKIM work?

DKIM is compatible with existing email infrastructure and works with SPF and DMARC to create multiple layers of security for domains sending emails. It uses public-key cryptography to sign an email with a private key as it is sent out from the sender server.

Recipient servers then use a public key published to a domain’s DNS to verify the source of the message and to make sure that the email was not altered in transit. Once the signature is verified with the public key by the recipient server, the email passes DKIM and is considered authentic.

Errors while sending emails due to DKIM Rejects

1. Error in DKIM public key, DKIM public key not found in DNS
   The DKIM public key record from your DNS is missing.Most commonly it can  happen due to some mistake while configuring dns records manually.  We request you to add back the same and then attempt to send an email.
2. Error in DKIM public key, invalid DKIM key format
   The DKIM key added to your DNS panel might have some incorrect values or incorrect formatting. Please ensure that you copy the exact DKIM value from the Control Panel. Once your DKIM key is reverified it may take some time to reflect the changes which should be up to your DNS TTL.
3. Error in DKIM public key, more than one TXT record in same selector
   The DKIM public record added to your DNS  has more than one TXT value. Titan doesn't allow multiple dkim key records to avoid conflicts under same selector. Hence, please ensure that you paste the exact value from the Control Panel. Once your DKIM key is reverified it may take some time to reflect the changes which should be up to your DNS TTL
