[iriveymg] Error correcting email addresses

Create an email domain whose addresses contain error correcting code information.  It is not defeated by bad handwriting or other transcription errors.  Easiest is probably addresses that contain only digits, including check digits.

Need to publicize a method with which a sender can detect and correct errors in a corrupted address.

Ambitiously, deploy the idea to much more than just the username part of an email address.  An entire URL.  Federated system with many possibly error correcting codes, perhaps some able to correct more errors.  Would need to redo DNS.
