Schleuder has it's own gpg key, and also it's own keyring that you can use if you are subscribed to the list.

When using X-RESEND you need to add also the line X-LIST-NAME line to your email, and send it signed:

You could also add their key to your schleuder mailing list, with

X-LIST-NAME: listname@withtheemail.org
X-ADD-KEY:

And then do:

X-LIST-NAME: listname@withtheemail.org
X-RESEND-ENCRYPTED-ONLY: person@nogpgkey.org

Getting the keys on a Schleuder list keyring

X-LIST-NAME: listname@withtheemail.org

Administration

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.

For more details see https://schleuder.nadir.org/docs/.

Schleuder runs on Eugeni. The version of Schleuder currently installed is: 3.1.2

Mailing lists are managed through schleuder-cli which needs schleuder-api-daemon running. If the daemon is not running you can start it with:

SCHLEUDER_CONFIG="/srv/schleuder.torproject.org/data/schleuder.yml" schleuder-api-daemon 

Lists also need to be setup in postfix in order to forward to Schleuder.

To create a list you can:

schleuder-cli lists new secret-team@lists.torproject.org admin@torproject.org /path/to/public.key

Schleuder will create the list gpg key together with the list. Please not that the created keys do not expires. For more information about how Schlueder creates keys you can check: https://0xacab.org/schleuder/schleuder/blob/master/lib/schleuder/list_builder.rb#L120

schleuder-cli keys export secret-team@lists.torproject.org <list-key-fingerprint>
