Cypherpunk Mailboxes?
-----BEGIN PGP SIGNED MESSAGE----- Hi, I have a thought for addressing the anon. problem. We could create a network of anonymous remailers with mailboxes. All messages in the mailboxes are stored encrypted. No information about the users are keep. Users would be be given x K of mailbox space. We could use PGP keys for encrypting the messages. Each user would have his own key pair for his anonymous mailbox. Any plain text messages received to the server would be encrypted on recept.

The only problem is there has to be someway for users to retrieve their mail. The current nym server approach is to use an encrypted reply block to send a user new mail. This way the nym server doesn't know who the user is. If users have to actively retrieve their mail, then the feds could install a packet sniffer on the remailers net link to find out the real email address of an anonymous user. - -- Mark PGP encrypted mail prefered.

Hrmm.. perhaps there's a better way... such as having the user and the mail server negoiae a key (i don't really know the details of diffie-hellman or he like, so tell me if this isn't feasable), and have the encryption/decypion routines strip addresses, so that the person is only identifiable by their key... anybody see what i'm saying? --Deviant All extremists should be taken out and shot.

The mail server still has to send packets to the user. A packet sniffer might not be able to find out the actual contents of the transmission, but it would be able to find out the host that has made the connection. If this is combined with the knowledge of the times that certain user's mailboxes get cleared out, it would be possible to find out which nyms belong to which people. The current nym servers that automatically forward mail do not have this problem. - -- Mark PGP encrypted mail prefered.
