Confidant Mail now has a beta encrypted mailing list feature. It works like a normal mailing list in that you send a message to the listserv address and the message is remailed to all the recipients. Unlike regular mailing lists, access is controlled by public keys, so only a list of approved keys can send to the list. The messages are signed by the listserv's key, and by clicking Show Original you can also check the signature of the original sender. Large file attachments can be included in mailing list posts. Confidant Mail can operate through Tor or I2P, so anonymous participants can take part in a discussion without exposing their real-world identities. In addition to the mailing list feature, I have added a file server. You can send attachments to the file server, and they will be saved to a shared directory. Other users can send get requests to retrieve the files. There is an access control list, so specific public keys can be granted read-only, write, or overwrite access. Using the mailing list and file server, it is easy for a small group to collaborate on a project while some or all of them remain anonymous. Even the operator of the listserv can be anonymous behind Tor. Please email me if you want to help test this out. Mike Ingle <mike@confidantmail.org> d2b89e6f95e72e26e0c917d02d1847dfecfcd0c2
