public-inbox - an "archives first" approach to mailing lists
------------------------------------------------------------
+
public-inbox implements the sharing of an email inbox via git to
complement or replace traditional mailing lists. Readers may
-read via NNTP, Atom feeds or HTML archives.

public-inbox spawned around three main ideas:
-* Publically accessible and archived communication is essential to
- Free and Open Source development.
-* Contributing to Free and Open Source projects should not require the
- use of non-Free/non-Open Source services or software.

public-inbox aims to be easy-to-deploy and manage; encouraging projects
to run their own instances with minimal overhead.
Implementation
--------------
-public-inbox uses ssoma[1], Some Sort Of Mail Archiver which implements
-no policy of its own. By storing (and optionally) exposing an inbox
-via git, it is fast and efficient to host and mirror public-inboxes.
-Traditional mailing lists use the "push" model. For readers, this
-requires commitment to subscribe and effort to unsubscribe. New readers
-may also have difficulty following existing discussions if archives do
-not expose Message-ID headers for responses. List server admins may be
-burdened with delivery failures.
+public-inbox stores mail in git repositories as documented
+in https://public-inbox.org/public-inbox-v2-format.txt and
+https://public-inbox.org/public-inbox-v1-format.txt
-public-inbox uses the "pull" model. Casual readers may also follow
-the list via NNTP, Atom feed or HTML archives.

-Users of the ssoma[1] command-line tool may import mail into an mbox,
-Maildir, or IMAP folder from git repositories periodically.

_Anybody_ may also setup a delivery-only mailing list server to
replay a public-inbox git archive to subscribers via SMTP.

Requirements for reading:
-* any software capable of NNTP or following Atom feeds
+* any software capable of IMAP, NNTP or following Atom feeds
Any basic web browser will do for the HTML archives.
We primarily develop on w3m to maximize accessibility.
* any MUA which may send text-only emails ("git send-email" works!)
Users are strongly encouraged to use the "reply-all" feature of
- their mailers to reduce the impact of a public-inbox as a SPOF.
+ their mailers to reduce the impact of a public-inbox as a
+ single point of failure.
+
+* The HTTP web interface exposes mboxrd files, and NNTP clients often
+ feature reply-by-email functionality
* participants do not need to install public-inbox, only server admins

Anti-Spam
---------
+
The maintainer of public-inbox has found SpamAssassin a good tool for
filtering his personal mail, and it will be the default spam filtering
tool in public-inbox.

Content Filtering
-----------------
-To discourage phishing, web bugs (tracking), viruses and other nuisances,
-only plain-text content is allowed and non-text content is stripped.
-This saves I/O bandwidth and storage, which is important as
-entire mail archives are shared between clients.
+
+To discourage phishing, trackers, exploits and other nuisances,
+only plain-text emails are allowed and HTML is rejected by default.
+This improves accessibility, and saves bandwidth and storage
+as mail is archived forever.
As of the 2010s, successful online social networks and forums are the
ones which heavily restrict users formatting options; so public-inbox
