1 public-inbox - an "archives first" approach to mailing lists
2 ------------------------------------------------------------
3 public-inbox implements the sharing of an email inbox via git to
4 complement or replace traditional mailing lists. Readers may
5 subscribe to a mailing list using ssoma[1] (a git-wrapper) to
6 import email from a git repository into an IMAP folder, Maildir,
7 or mbox. Readers may also read via Atom feeds and HTML archives.
9 public-inbox spawned around three main ideas:
11 * Publically accessible and archived communication is essential to
12 Free and Open Source development.
13 * Contributing to Free and Open Source projects should not require the
14 use of non-Free/non-Open Source services or software.
15 * Graphical user interfaces should not be required for text-based
18 public-inbox aims to be easy-to-deploy and manage; encouraging projects
19 to run their own instances with minimal overhead.
23 public-inbox uses ssoma[1], Some Sort Of Mail Archiver which implements
24 no policy of its own. By exposing an inbox via git, readers may follow
25 the inbox without subscribing via SMTP and have easy access to old
28 Traditional mailing lists use the "push" model. For readers, this
29 requires commitment to subscribe and effort to unsubscribe. New readers
30 may also have difficulty following existing discussions if archives do
31 not expose Message-ID headers for responses. List server admins may be
32 burdened with delivery failures.
34 public-inbox uses the "pull" model. Readers import mail into an mbox,
35 Maildir, or IMAP folder from git repositories periodically. If a reader
36 loses interest, they simply stop syncing. Since we use git, mirrors are
37 easy-to-setup, and lists are easy-to-relocate to different mail
38 addresses without losing/splitting archives. Dedicated readers only
39 need to install ssoma, a command-line tool[1] currently implemented in
42 Casual readers may also follow the list via Atom feed or web archives.
44 _Anybody_ may also setup a delivery-only mailing list server to replay
45 a public-inbox git archive to subscribers via SMTP.
47 [1] http://ssoma.public-inbox.org/
51 * anybody may participate via plain-text email
52 * stores email in git, readers have a complete archive of the inbox
53 * Atom feed allows casual readers to follow via feed reader
54 * Mail user-agent (MUA) users may use Maildir, mbox(5) and/or IMAP locally
55 * uses only well-documented and easy-to-implement data formats

59 Requirements (Atom, read-only client)
60 -------------------------------------
61 * any feed reader capable of following Atom feeds
63 Any basic web browser will do for the HTML archives.
65 Requirements (participant)
66 --------------------------
67 * ssoma - http://ssoma.public-inbox.org/
68 * any MUA which may send text-only emails ("git send-email" works!)
69 * participants do not need to install public-inbox, only server admins
73 See http://public-inbox.org/INSTALL
77 Source code is available via git:
79 git clone git://80x24.org/public-inbox
81 See below for contact info.
85 We are happy to see feedback of all types via plain-text email.
86 public-inbox discussion is self-hosting on public-inbox.org
87 Please send comments, user/developer discussion, patches, bug reports,
88 and pull requests to our public-inbox address at:
92 Please Cc: all recipients when replying as we do not require
93 subscription. This also makes it easier to rope in folks of
94 tangentially related projects we depend on (e.g. git developers
95 on git@vger.kernel.org).
97 You may subscribe via ssoma(1), LISTNAME is a name of your choosing:
99 URL=git://public-inbox.org/meta
100 LISTNAME=public-inbox
102 # to initialize a maildir (this may be a new or existing maildir,
103 # ssoma will not touch existing messages)
104 # If you prefer mbox, use "ssoma add mbox ..." instead
105 ssoma add $LISTNAME $URL maildir:/path/to/maildir/
107 # read with your favorite MUA (only using mutt as an example)
108 mutt -f /path/to/maildir # (or /path/to/mbox)
110 # to keep your mbox or maildir up-to-date, periodically run the following:
113 # your MUA may modify and delete messages from the maildir or mbox,
114 # this does not affect ssoma functionality at all
116 # to sync all your ssoma subscriptions via cronjob
119 HTML inbox archives are available: http://public-inbox.org/meta/
123 The maintainer of public-inbox has found SpamAssassin a good tool for
124 filtering his personal mail, and it will be the default spam filtering
125 tool in public-inbox.
127 Readers may also use a custom mail-delivery-agent for delivery to enable
128 spam filtering by having ssoma deliver to a command via pipe.
130 There is unlikely to be any tool which is 100% accurate at classifying
131 spam, so it is possible to remove messages using the ssoma-rm(1) tool
136 To discourage phishing, web bugs (tracking), viruses and other nuisances,
137 only plain-text content is allowed and non-text content is stripped.
138 This saves I/O bandwidth and storage, which is important as
139 entire mail archives are shared between clients.
141 As of the 2010s, successful online social networks and forums are the
142 ones which heavily restrict users formatting options; so public-inbox
143 aims to preserve the focus on content, and not presentation.
