Schleuder is an email hub for groups. Subscribers can communicate encryptedly 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. Further Schleuder can send out its own public key and receive administrative commands by email. Email cryptography is handled by using GnuPG.
Configuration Schleuder reads its basic settings from a file that it by default expects at </etc/schleuder/schleuder.yml>. To make Schleuder read a different file set the environment variable SCHLEUDER_CONFIG to the path to your file when running schleuder. E.g.: SCHLEUDER_CONFIG=/usr/local/etc/schleuder.yml /path/to/bin/schleuder ... For explanations of the possible settings read the default config file. The default settings for new lists are read from another config file. By default Schleuder looks at </etc/schleuder/list-defaults.yml>. To make Schleuder read a different file set the environment variable SCHLEUDER_LIST_DEFAULTS analogous to above. The possible settings are explained in the default config file. Connect to MTA Schleuder behaves like an email-filter: it reads email from standard-input, and reports errors to standard-error. If all goes well Schleuder closes the initial connection to the Mail Transport Agent (MTA) only after it sent out all outgoing emails. In case of an error the MTA is expected to include Schleuder´s error message into a bounce-email that is sent back to the sender (this is default behaviour of most MTAs). To connect the MTA with Schleuder it must pipe the incoming message into Schleuder´s STDIN, and give it two arguments: first one: "work", second one: the full recipients email address. For more information on how to integrate Schleuder with your existing mail setup, please read the Schleuder documentation online (SEE ALSO). Data storage The keyrings for each list are standard GnuPG keyrings and sit in the filesystem under lists_dir/hostname/listname/ (lists_dir is read from schleuder.yml, by default it is </var/lib/schleuder/lists>). They can be used manually using gpg2. Please be careful to maintain proper file permissions if you touch the files. In the list-directory there’s also a list specific log-file (might be missing if the log-level is high and no error occurred yet). Other logging is sent to syslog. Where that ends up depends on the operating system and the system administration. All other list-related data is stored in the SQL-database. Most data is unserialized, only some values are JSON-encoded.
Schleuder features some special functionality. For more detailed information read the Schleuder documentation online (SEE ALSO). Getting the public key of a list Each Schleuder-list replies with its public key to any email sent to listname-sendkey@hostname. E.g. to receive the key for the contact address of the Schleuder project write an email to email@example.com. Email commands Schleuder knows some special keywords that trigger different behaviour. You can e.g. subscribe someone, or resend an email to a non-subscriber using keywords. Keywords require that: · they start the line and begin with "x-", · they are written into the beginning of the first text-part of the email (usually that’s just the normal body of the email), · possible arguments must be written on the same line as the keyword (exceptions are mentioned in the descriptions below), · the email must be encrypted and signed by a list-member’s key. Keywords can be repeated within one email at will. Letter case doesn’t matter. There are two types of keywords: those to enhance messages sent over the list (“list-keywords”), and those to request something from Schleuder (“request-keywords”). Find detailed descriptions of all available keywords in the Schleuder documentation online (SEE ALSO). Contact list-owner Write to listname-owner@hostname to contact the list-owner(s) even if you don´t know who they are. Use the list´s key to encrypt the email!
