  - name: 'mailman'

      - name: 'site_owner'
        comment: |
          This address is the "site owner" address.  Certain messages which must be
          delivered to a human, but which can't be delivered to a list owner (e.g. a
          bounce from a list owner), will be sent to this address.  It should point to
          a human.
        value: ''

      - name: 'noreply_address'
        comment: |
          This is the local-part of an email address used in the From field whenever a
          message comes from some entity to which there is no natural reply recipient.
          Mailman will append '@' and the host name of the list involved.  This
          address must not bounce and it must not point to a Mailman process.
        value: 'noreply'

      - name: 'default_language'
        comment: 'The default language for this server.'
        value: 'en'

      - name: 'sender_headers'
        comment: |
          Membership tests for posting purposes are usually performed by looking at a
          set of headers, passing the test if any of their values match a member of
          the list.  Headers are checked in the order given in this variable.  The
          value From_ means to use the envelope sender.  Field names are case
          insensitive.  This is a space separate list of headers.
        value: [ 'from', 'from_', 'reply-to', 'sender' ]

      - name: 'email_commands_max_lines'
        comment: 'Mail command processor will ignore mail command lines after designated max.'
        value: 10

      - name: 'pending_request_life'
        comment: |
          Default length of time a pending request is live before it is evicted from
          the pending database.
        value: '3d'

      - name: 'cache_life'
        comment: 'How long should files be saved before they are evicted from the cache?'
        value: '7d'

      - name: 'pre_hook'
        comment: |
          A callable to run with no arguments early in the initialization process.
          This runs before database initialization.
        value: ''

      - name: 'post_hook'
        comment: |
          A callable to run with no arguments late in the initialization process.
          This runs after adapters are initialized.
        value: ''

      - name: 'layout'
        comment: |
          Which paths.* file system layout to use.
          You should not change this variable.
        value: 'debian'

      - name: 'filtered_messages_are_preservable'
        comment: 'Can MIME filtered messages be preserved by list owners?'
        value: False

      - name: 'html_to_plain_text_command'
        comment: |
          How should text/html parts be converted to text/plain when the mailing list
          is set to convert HTML to plaintext?  This names a command to be called,
          where the substitution variable $filename is filled in by Mailman, and
          contains the path to the temporary file that the command should read from.
          The command should print the converted text to stdout.
        value: '/usr/bin/lynx -dump $filename'

      - name: 'listname_chars'
        comment: |
          Specify what characters are allowed in list names.  Characters outside of
          the class [-_.+=!$*{}~0-9a-z] matched case insensitively are never allowed,
          but this specifies a subset as the only allowable characters.  This must be
          a valid character class regexp or the effect on list creation is
        value: '[-_.0-9a-z]'

  - name: 'shell'
    separator: True
    comment: |
      `mailman shell` (also `withlist`) gives you an interactive prompt that you
      can use to interact with an initialized and configured Mailman system.  Use
      --help for more information.  This section allows you to configure certain
      aspects of this interactive shell.

        value: 'Welcome to the GNU Mailman shell'

      - name: 'use_ipython'
        comment: |
          Use IPython as the shell, which must be found on the system.  Valid values
          are `no`, `yes`, and `debug` where the latter is equivalent to `yes` except
          that any import errors will be displayed to stderr.
        value: False

      - name: 'history_file'
        comment: |
          Set this to allow for command line history if readline is available.  This
          can be as simple as $var_dir/ to put the file in the var directory.
        value: ''

  - name: 'paths.debian'
    separator: True
    comment: |
      Important directories for Mailman operation.  These are defined here so that
      different layouts can be supported.   For example, a developer layout would
      be different from a FHS layout.  Most paths are based off the var_dir, and
      often just setting that will do the right thing for all the other paths.
      You might also have to set spool_dir though.

      Substitutions are allowed, but must be of the form $var where 'var' names a
      configuration variable in the paths.* section.  Substitutions are expanded
      recursively until no more $-variables are present.  Beware of infinite
      expansion loops!

      - name: 'var_dir'
        comment: |
          This is the root of the directory structure that Mailman will use to store
          its run-time data.

          There are also a number of paths to specific file locations that can be
          defined.  For these, the directory containing the file must already exist,
          or be one of the directories created by Mailman as per above.

          Use this to set the Storm database engine URL.  You generally have one
          primary database connection for all of Mailman.  List data and most rosters
          will store their data in this database, although external rosters may access
          other databases in their own way.  This string supports standard

      This defines various log settings.  The options available are:

      - level     -- Overrides the default level; this may be any of the
                     standard Python logging levels, case insensitive.
      - format    -- Overrides the default format string
      - datefmt   -- Overrides the default date format string
      - path      -- Overrides the default logger path.  This may be a relative
                     path name, in which case it is relative to Mailman's LOG_DIR,
                     or it may be an absolute path name.  You cannot change the
                     handler class that will be used.
      - propagate -- Boolean specifying whether to propagate log message from this
                     logger to the root "mailman" logger.  You cannot override
                     settings for the root logger.

      In this section, you can define defaults for all loggers, which will be
      prefixed by 'mailman.'.  Use subsections to override settings for specific
      loggers.  The names of the available loggers are:

      - archiver        --  All archiver output

      - database        --  Database logging (SQLAlchemy and Alembic)
      - debug           --  Only used for development
      - error           --  All exceptions go to this log
      - fromusenet      --  Information related to the Usenet to Mailman gateway
      - http            --  Internal wsgi-based web interface
      - locks           --  Lock state changes
      - mischief        --  Various types of hostile activity
      - runner          --  Runner process start/stops

      - smtp-failure    --  Unsuccessful SMTP activity

          Where can we find the mail server specific configuration file?  The path can
          be either a file system path or a Python import path.  If the value starts
          with python: then it is a Python import path, otherwise it is a file system
          path.  File system paths must be absolute since no guarantees are made about
          the current working directory.  Python paths should not include the trailing
          .cfg, which the file must end with.
