Domainkeys for multiple domains

[SuperBadConchord]

Im trying to implement domainkeys onto my domains, but when I select "Use DomainKeys spam protection system to sign outgoing email messages" in the mail setting it only applies to to my server hostname and to none of my domains. How do I apply domainkeys to all of my domains? The version of plesk im using is centos 11.5.30
