Just recently NA providers have introduced an encrypted mail. It requires a PC client to encrypt the message. User retrieving the message does not need a client but requires a password.

E.g. user controls her sender/recipient list and filters out all others. --- David Morris <dwm@xxxxxxxxx> wrote: > > > On Wed, 6 Dec 2006, Hallam-Baker, Phillip wrote: > > > I agree that this demonstrates that the 'charge per email' schemes that > > people have don't work. > > It doesn't demonstrate any such thing.
