1. Generate the key “How you go about creating and implementing a DKIM key will vary depending on your email service.” If you are configuring DKIM on your email servers directly, you will need to generate an RSA public/private key pair. We recommend you use a 2048-bit key. There are several good guides on how to generate RSA key pairs for Windowsor Linux.

2. Generate the key “If you use a cloud-based email service, your DKIM configuration will be automated to some extent.” If you are configuring DKIM on your email servers directly, you will need to generate an RSA public/private key pair. We recommend you use a 2048-bit key. There are several good guides on how to generate RSA key pairs for Windowsor Linux.

Create a new key with a new selector and follow the same steps as above. Keep the old DNS record live for a few days after making changes, to give the DNS time to update.
