TESTING

openarc.org provides infrastructure you may use to get familar with ARC.

1. Autoresponder

Send a message to echo@openarc.org. You'll receive a response seconds later. This response contain the message as received by the service. This allowes you to inspect how OpenARC validate your sent message.

2. Forwarder

Send a message to forward@openarc.org. You'll receive your message forwarded back to you seconds later. It's not a new one. Existing DKIM signatures are expected to be still intact after forwarding.

But you may force message modification to invalidate your existing DKIM signature: Choose the text "modify" as Subject and it will be prepended with "[MODIFIED]: " on forwarding. Your DKIM signature will be no longer valid. We assume you sign the RFC5322.Subject header as advised by RFC 6376 - DKIM Signatures

3. Mailing-List

Subscribe to the mailing-list openarc-testing@openarc.org first. Then you may send messages to openarc-testing@openarc.org. As usual your message is resend to all subscriber. There is no public list archive as that donsn't make sense.
