BradKoehn[m] * This question exposes a flaw in the current implementations of AP: there is no mechanism to allow forwarded messages to be verified. In email, DKIM can be used to guarantee that forwarded messages are authentic; no such capability exists in AP, and http-signatures can only be used to insure that the forwarder is valid, and cannot insure the forwarded message is valid.
