Re: [Ietf-dkim] Testing a DKIM implementation
My answer here would be the same one I give users of a mailing service wondering about their DKIM signatures: send it to all the major mailbox providers and check the Authentication-Results headers. If they pass, your users will be able to successfully send to them, which is what really counts in the end. That said, https://aboutmy.email is a good tester.
