The service is provided cooperatively by the user's desktop computers, and ePOST provides better security and fault tolerance than existing email systems. Email exchanged between ePOST users is cryptographically sealed and authenticated and the service remains available even when traditional mail servers have failed. ePOST gives users plenty of email storage (users can use as much as they contribute of their own disk space). Moreover, users don't have to entrust their email to a commercial provider, who may mine thier data, target them with advertisement or start charging them once they're hooked. ePOST has been running as the primary email system for members of our group for over a year. ePOST works by joining a peer-to-peer network running a personal IMAP and SMTP server on your desktop, which is only for your email. ePOST is backward compatible with existing email systems, and your ePOST email address works just like a normal email address - you can send and receive messages from non-ePOST users. Additionally, you can use your existing email clients with ePOST, since ePOST provides standard IMAP and POP3 servers. A few of other features of ePOST are: - support for SSL connections - a data durability layer called Glacier, providing durability with up to 60% member node failures - support for laptops and machines behind NATs - support for networks with routing anomalies More information about ePOST is available at http://www.epostmail.org/. We now welcome additional ePOST users. If you are interested in seting up an ePOST account, please follow the installation instructions posted at http://www.epostmail.org/install.html. Most ePOST users have set up mail forwarding so that a copy of incoming mails are kept on their normal mail server, in addition to being forwarded to their ePOST account. We recommend this setup until ePOST is no longer in beta status, although we have not found an instance yet where using this backup was necessary to recover a lost email. Also, please let us know if you are interested in running a local ePOST ring at your institution. Running such a ring allows organizations to ensure all overlay traffic remains internal to the organization, while maintaining global connectivity. More information on running an organizational ring is available at http://www.epostmail.org/deploy.html. We are currently collecting high-level statistics from all of the ePOST nodes in our deployment for research purposes. These statistics concern the number of overlay messages sent and the amount of data stored on disk. We are not recording the plain text of emails, nor are we examining which users are exchanging emails. If the collection of statistics would prevent you from using ePOST, please don't hesitate to contact us, and we can turn these features off for you. Thanks again for your help, and don't hesitate to ask us any questions, comments, or suggestions, Alan Mislove, Ansley Post, Andreas Haeberlen, and Peter Druschel ([EMAIL PROTECTED]) _______________________________________________ p2p-hackers mailing list [EMAIL PROTECTED] http://zgp.org/mailman/listinfo/p2p-hackers _______________________________________________ Here is a web page listing P2P Conferences: http://www.neurogrid.net/twiki/bin/view/Main/PeerToPeerConferences --- end forwarded text -- ----------------- R.
