So how do we solve it? By abandoning return addresses and using mail spool facilities.

1. I have a machine and I'll sell you an address on it...
2. When mail come in for you, it sits in a spool...
3. Your mail sits in the spool until you access it with... a mail server command of "send me a mailbox file of my waiting mail".

The elimination of persistent identifying information for return paths is a worthwhile design objective. I propose that we start thinking about it more thoroughly.

Let me see if I understand your idea correctly. I am picturing something like the following: There will exist a bunch of remailers that, in addition to forwarding mail, will also sell mailboxes. (I'm combining the remailer with the mail spools to add to the mix of messages to and from). The "mailboxes" are actually e-mail addresses referring to a pseudo-account on some machine that hosts a remailer/mail spooler. Bob would purchase a number of mailboxes scattered throughout the remailer/mail spooler system. Bob would give out the address of one of these mailboxes to people so they can send "reply" messages to him. Messages addressed to Bob's "public" mailbox would be spooled by the remailer hosting that mailbox. Periodically (perhaps frequently), Bob would send an anonymous message (via other remailers) to the remailer hosting his public mailbox to command the remailer to send the contents of his mailbox to one of his other mailboxes. The remailer wouldn't necessarily know it's sending to another mailbox, it's just sends to an address supplied in the command message. Bob repeats this process to move his messages from his second mailbox to his third mailbox, and so on. Eventually, he moves his messages from his Nth mailbox to his "real" address. Is this approximately what you had in mind? I left out IP redirectors and POP clients because I'm not familiar with them. Jim_Miller@suite.com
