Proposal of OpenPGP Email Validation

[listo factor]

The problem with most "e-mail reform" proposals (this one included)
is that they don't address what is the primary problem of essential
users of the encrypted communication: that to their attackers the
knowledge of who communicates with whom is of greater value than
the content of the message. Without solving that primary problem,
the motivation for the adoption of any new scheme is either low
or non-existent.
