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.

Kucherawy, who was most helpful in answering my previous questions about specifics of RFC6376.. I now have my implementation complete: I was wondering if there is a recommended way of testing it - for instance, a reference site that allows you to send messages and then replies with information about the correctness of your implementation, or an application that can generate signatures for data you supply, showing its work product (the various hashes and canonicalized forms) so you can compare it with your own. Any pointers would be appreciated. Thanks in advance for any assistance. -- David -- ------------------ David Harris -+- Pegasus Mail ---------------------- Box 5451, Dunedin, New Zealand | e-mail: david.har...@pmail.gen.nz Phone: Number provided on request only.
