mail delivery agent for public-inbox


  public-inbox-mda </path/to/RFC2822_message


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)



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



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).


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

Default: ~/.public-inbox/config


emergency Maildir destination.

Default: ~/.public-inbox/emergency/
