To configure DKIM for different domains, you need to follow these steps:
1. Generate a DKIM key pair for each domain that you want to configure DKIM for.
1. Insert the public key into the DNS record for the domain.
1. Add the private key to your DKIM signer software or email platform.
1. Set up your email server to include a DKIM signature in outgoing email for each domain that you want to configure DKIM for.
1. Verify that the DKIM signature is being applied correctly by sending test emails and checking the DKIM signature in the email header.
1. Monitor your DKIM logs and reports for any issues or errors.
1. Periodically review and update your DKIM configurations as needed.
Note that the specific steps and tools required for DKIM configuration may vary depending on your email platform and DNS provider. It is recommended to consult the documentation for your specific platform or seek assistance from a qualified professional.
