Hi Miriam,

Besides technical problems stated already by others there is a more 
serious reason why i would not support this scheme.

This scheme above is based on the premise that everybody can email with 
no need for anonymity.  In most cases this will be true when you are 
living in the western world. Even there though, you may have good 
reasons to want anonymity (consider whistle blowers, who often end up in 
deep trouble when doing it publicly).

More serious though, is the situation in countries like China, where 
this may lead to prison sentences or worse.

The problem with you scheme is that it makes anonymous email impossible.


Cheers,


Rudy
