ssoma - some sort of mail archiver
ssoma is a git-based mail archiver and transport.  Email is injected via
ssoma-mda(1) (MDA: mail delivery agent) on a server and may be shared
(via git) and extracted to mbox, Maildir, or IMAP via ssoma(1).  ssoma
exists primarily as the mechanism (not policy) for public-inbox but may
easily be used for other projects.

Readers of public-inbox instances may install ssoma to extract messages
into their favorite mail client for reading.

See for more information on how ssoma is used.

* stores email in git, so readers have a full history of the mailing list
* mail user-agent (MUA) users may choose from IMAP, mbox(5), and Maildir
* uses only well-documented and easy-to-implement data formats

Installation should be easy and require only a few, commonly-available
packages.  See for details.

Source code is available via git:

	git clone git://

We are happy to see feedback of all types via plain-text email.
Please email comments, user/developer discussion, patches, bug reports,
and pull requests to the public-inbox discussion list at:

Please Cc: all recipients when replying (this is not a requirement of
public-inbox or ssoma, but a good idea since we do not require
subscription).  This also makes it easier to rope in folks of
tangentially related projects we depend on (e.g. git developers on

You can subscribe via ssoma, LISTNAME is a name of your choosing:


    # to initialize a maildir (this may be a new or existing maildir,
    # ssoma will not touch existing messages)
    # If you prefer mbox, use mbox:/path/to/mbox as the last argument
    ssoma add $LISTNAME $URL maildir:/path/to/maildir

    # read with your favorite MUA (only using mutt as an example)
    mutt -f /path/to/maildir # (or /path/to/mbox)

    # to keep your mbox or maildir up-to-date, periodically run the following:
    ssoma sync $LISTNAME

    # your MUA may modify and delete messages from the maildir or mbox,
    # this does not affect ssoma functionality at all

    # to sync all your ssoma subscriptions
    ssoma sync

    # You may wish to sync in your cronjob
    ssoma sync --cron

Mail repository format
If you are uncomfortable running code in ssoma for any reason and
would rather read directly from the git repository, the following
