The steps for setting up DKIM (DomainKeys Identified Mail) are:
1. Generate a DKIM key pair: Generate two keys, one private and one public. The private key is kept secret and is used to sign outbound emails. The public key is published in DNS to allow receivers to verify the signature.
1. Add a DNS TXT record: Insert a DNS TXT record containing the public key in the domain’s DNS zone. This record is published in DNS so email receivers can access it and verify the signature on incoming emails.
1. Configure email sending software: Configure the email sending software to include the DKIM signature in outbound email messages. This involves adding the signature header and signing the email with the private key.
1. Monitor and test email: Monitor email delivery and test the configuration to ensure that DKIM is working correctly. This includes confirming that the DKIM signature is present in outbound emails and that incoming emails are verified as authentic.
1. Maintain DKIM configuration: Keep the DKIM configuration up-to-date and in alignment with other email security measures like SPF and DMARC to ensure that emails are verified as authentic and delivered to the recipient’s inbox.
