How do I use the Registered Receipt e-mail as verifiable proof?
If there is ever a dispute regarding the delivery or content of the message or attachment, the receipt can be authenticated by simply forwarding it to the RPost verification address located on the receipt. The RPost system unlocks the encrypted attachment, regenerates digital fingerprints and hashing data to prove its integrity, and sends the original back to the person who submitted the receipt for verification. The Registered Receipt e-mail is very durable, meaning that it can be forwarded to any disputing party and they can authenticate the receipt. It can even be saved onto CD or keychain micro-drive and brought to an arbitrator for authentication. In every case, the RPost system will regenerate the original e-mail and all attachments if authentic, but otherwise deliver a notice that the e-mail had been tampered subsequently and no longer valid where that is determined to be the case.
