When I reactivate the domain as a web service, this error doesn't occur. It only happens when a domain is configured without a web service, for example, solely for emails.
As long as the error is not fixed, I need to do the following for newly created domains:
/opt/psa/bin/domain_pref --update example.com -sign_outgoing_mail true
Hello, I have the same issue. Even after enabling DKIM for newly created domains, there is no key visible. Also, no directory is created under "/etc/domainkeys/" for new domains. This has been the case since the second-to-last update.
