Add a TXT record to the domain's DNS that contains the public key and the selection (for example, selector1. domainkey.example.com).
Include the right DKIM record syntax, which may differ depending on the DNS provider.
DKIM (DomainKeys Identified Mail) is a security approach used by email providers to detect whether or not an incoming email was sent by a legitimate source. It works by appending a digital signature to the email's header, which the receiver then validates using the public key contained in the domain's DNS records.
You may not need to build a DKIM record if you use a third-party ESP (Email Service Provider). Many ESPs will handle DKIM signature establishment and administration on your behalf. To find out if the ESP handles DKIM setup and administration, see their documentation or support staff.
To create a DKIM record, follow these steps:
- Make a private key to sign outgoing emails with.
- Make a public key out of the private key.
How To deploy a DKIM Record Generator, follow these steps:
- Enter the domain name and selection details.
- Create a private key for outgoing email signatures.
- The generator will then generate the public key as well as a DKIM record template that can be added to the domain's DNS.
