Click Generate Keys. The DKIM Setup page will provide you with a host name and a public key.
Contact your DNS Provider to make these changes (this may be your hosting company, domain name registrar, or another provider. Larger organizations may host their DNS Tables in-house). Refer to your provider's documentation for specific instructions.
Create a new TXT DNS entry with the provided host name and key. The information must match exactly what is presented in the Control Console, and must not include hidden characters, such as spaces.
Save your DNS Changes. You may have to wait 24-48 hours to proceed.
Return to the Control Console and go to Email Protection, Setup, DKIM Setup.

NOTE: You must have an outbound server package, and it must be configured with mail flowing through the Email Protection Smart Host for DKIM to work properly. If you direct outbound mail from Email Protection, mail may bounce depending on how the recipient handles failed DKIM signatures.
