Schleuder is a gpg-enabled mailing list manager with resending-capabilities. Subscribers can communicate encrypted (and pseudonymously) among themselves, receive emails from non-subscribers and send emails to non-subscribers via the list.
Schleuder takes care of all de- and encryption, stripping of headers, formatting conversions, etc.
But Schleuder can also receive and send emails to non-subscribers, which makes it a useful email hub for groups.
Incoming emails from non-subscribers (“outside people”) are (re)encrypted and distributed among the subscribers, which can communicate internally as well as answer to the outside person via the list.
The outside person only sees an email address with a public key, but has no information about who is behind it.
Schleuder can send out its own public key upon request by email.
Version 3 of schleuder is a complete rewrite, which aims to be more robust, flexible, and internationalized. It also provides an API for the optional web interface called schleuder-web.
