Did you read the spec? This has very little to do with control. All that DomainKeys allow you to do is provide a mechanism so that other mail servers can verify that you can mail from the domain that you are claiming to be From. This includes your own domain. Hell, Domainkeys doesn't even require that the source MTA do the signing; a properly configured MUA could sign instead, which means that it doesn't automatically break forwarding setups or roaming users, but it does help verify that joe@example.com actually belongs to example.com.
