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

SYNOPSIS
         public-inbox-mda </path/to/RFC2822_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/
