Why not post messages to usenet alt.anonymous.messages? It can provide great properties for privacy and anonymity. You don't need any servers or to invent any server software. Just use the existing infrastructure.
alt.anonymous.messages can be used as a big shared mailbox. And the client application could figure out which messages its supposed to read. You don't even need to fill out a sign up form. Similar to http://quicksilvermail.net, which has a great concept. But its windows only, although there are no conceptual restrictions for being windows only. Its user interface is too complicated. A rewrite in another language, better interface and it could be a great application. Anonymity: You don't have to use mixmaster to send mails to alt.anonymous.messages. Anonymity wasn't the point of this proposal? But if you wanted to add anonymity, you could post using the mixmaster network over Tor. When fetching alt.anonymous.messages over Tor, neither ISP's or servers could figure out who is fetching new mails. Comments on mixmaster: Please refer to mixmaster as a tool to send mails and discard the anonymity aspects. [1] [2] Although the network is quite old and small, the remaining node operators are active on the remops list and not looking like they are about to shut down the network. There are even some new developments on github (mixfaster). I've been experimenting with the mixmaster remailer network. It works reliable. Sending a mail takes approximately 5 to 30 minutes, when using a one hop mixmaster node. [1] In theory, remailers or to be more specific, high latency networks are more secure than low latency networks like Tor. The anonymity provided by the remailer would add up to the anonymity provided by Tor. Given the facts, the there is almost no activity activity (press, blog posts, forum, mailing list discussion, development ceased) it's easy to assume that remailers have very few remaining servers and users and add not much anonymity in practice.
