-public-inbox uses ssoma[1], Some Sort Of Mail Archiver which implements
-no policy of its own. By exposing an inbox via git, readers may follow
-the mailing list without subscribing via SMTP and have easy access to
-old messages.
-
-Traditional mailing lists use the "push" model. List servers deliver
-content via SMTP to other mail servers used by readers of the mailing
-list. For readers, this requires commitment to subscribe to the list
-and extra 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 are also burdened with
-occasional bounce messages.
-
-public-inbox uses the "pull" model. Readers import mail into an mbox,
-Maildir, or IMAP folder from git repositories periodically. If a reader
-loses interest, they simply stop syncing. Since ssoma uses git,
-mirrors are easy-to-setup, and lists are easy-to-relocate to different
-mail addresses without losing/splitting archives. Dedicated readers
-only need to install ssoma, a command-line tool[1] currently implemented
-in Perl.
-
-Casual readers may also follow the list via Atom feed or web archives.
-
-_Anybody_ may also setup a delivery-only mailing list server to replay
-a public-inbox git archive to subscribers via SMTP.
