NAME
    public-inbox-mda - mail delivery agent for public-inbox

SYNOPSIS
    public-inbox-mda <MESSAGE

DESCRIPTION
    Mail Delivery Agent (MDA) for public-inbox installations. Each system
    user may have their own public-inbox instances. This may be invoked via
    procmail(1) or similar tools.

    By default, it relies on spamc(1) for filtering mail, but may be
    disabled via "publicinboxmda.spamcheck" in public-inbox-config(5)

OPTIONS
    --no-precheck
            By default, public-inbox-mda does some simple checks before
            invoking spamc(1) since it is intended to receive mail before it
            goes to a mailing list.

            However, some users prefer to use public-inbox-mda to mirror
            mailing lists. This option exists to support those users.

            Using this option, the following prechecks are disabled:

              * multiple Message-IDs
              * non-existent Message-IDs
              * Message-IDs longer than 244 characters long
              * From: header shorter than 3 characters
              * Subject: header shorter than 2 characters
              * unusable Date: headers
              * inbox address specified in To: or Cc: header

ENVIRONMENT
    ORIGINAL_RECIPIENT
            The original recipient email address, set by the MTA. Postfix
            sets it by default, untested on other MTAs.

            This does not have to be set if relying on
            "publicinbox.$NAME.listid" directives configured in
            public-inbox-config(5).

    PI_CONFIG
            Per-user config file parseable by git-config(1). See
            public-inbox-config(5).

            Default: ~/.public-inbox/config

    PI_EMERGENCY
            emergency Maildir destination.

            Default: ~/.public-inbox/emergency/
