Should I continue to use DomainKeys?

When DomainKeys Identified Mail (DKIM) was put into practice, it made the use of DomainKeys obsolete. If your sending domain has both DKIM and DomainKeys set up and they are validating correctly, there is no need to remove Domainkeys unless authenticating with Domainkeys takes up too many server resources. New domains should use DKIM instead of Domainkeys.
