Checking your DKIM configuration involves several steps:
Generate a DKIM key: This can usually be done through your email service provider or your domain registrar. Add the DKIM record: Add the DKIM public key to your domain's DNS settings. Verify the DKIM record: Use tools like DKIMCore or MXToolbox to ensure the DKIM record is correctly configured. Send a test email: Send an email to a service like MailTester to check if DKIM is properly signed.
