[Mailman-Users] [Mailman-Announce] Mailman 2.1.16 release.

I am pleased to announce the third release candidate for Mailman 2.1.16.

Python 2.4 is the minimum supported, but Python 2.7 is recommended.

This release has a few new features and several bug fixed as detailed in
the attached README.

Differences from the second candidate are the renaming of the
author_is_list feature to from_is_list to more accurately describe what
it does. This feature has also been extended to provide the option of
leaving the original message intact and wrapping it in an outer part
with Content-Type: message/rfc822.

The from_is_list feature is considered experimental and subject to
change in future releases. It is being released now as a "candidate" to
allow some exposure before the final 2.1.16 release which should occur
in October.

Mailman is free software for managing email mailing lists and
e-newsletters. Mailman is used for all the python.org and
SourceForge.net mailing lists, as well as at hundreds of other sites.

For more information, please see:


Mailman 2.1.16rc3 can be downloaded from


I anticipate that the 2.1.16 final release will be in Mid October.
Bugs found between now and then will be fixed if possible, but I hope
that most if not all changes between now and then will be i18n updates.
Please send any updates to the templates and/or message catalogs in the
2.1.16rc3 release directly to me no later than 15 Oct 2013.

  New Features

    - There is a new list attribute from_is_list to either rewrite the From:
      header of posts replacing the posters address with that of the list or
      wrap the message in an outer message From: the list for compatability
      with DMARC and or ADSP.  There is a new mm_cfg.py setting
      DEFAULT_FROM_IS_LIST to control the default for new lists, and the
      existing REMOVE_DKIM_HEADERS setting has been extended to allow removing
      those headers only for certain from_is_list lists.  This feature must
      be enabled by setting ALLOW_FROM_IS_LIST to Yes in mm_cfg.py.  See the 
      description of these settings in Defaults.py for more detail.  This
      feature is experimental in 2.1.16, and it is subject to change or to
      become just one of the two methods in a subsequent release. People 
      interested in this feature are encouraged to try it and report their
      experiences to the mailman-users at python.org list.

    - There is a new DISPLAY_HELD_SUMMARY_SORT_BUTTONS setting which if set
      in mm_cfg.py will display a set of radio buttons in the admindb held
      message summary to select how the held messages are sorted and grouped
      for display. The exact setting determines the default grouping and
      sorting.  See the description in Defaults.py for details.

    - Setting digest_size_threshhold to zero now means no digests will be
      sent based on size instead of a digest being sent with every post.
      (LP: #558274)

    - There is a new mm_cfg.py setting SUBSCRIBE_FORM_SECRET which will put
      a dynamically generated, hidden hash in the listinfo subscribe form and
      check it upon submission.  Setting this will prevent automated processes
      (bots) from successfully POSTing web subscribes without first retrieving
      and parsing the form from the listinfo page.  The form must also be
      submitted no later than FORM_LIFETIME nor no earlier than
      SUBSCRIBE_FORM_MIN_TIME after retrieval.  Note that enabling this will
      break any static subscribe forms on your site.  See the description in
      Defaults.py for more info.  (LP: #1082746)

    - add_members now has an option to add members with mail delivery disabled
      by admin.  (LP: #1070574)

    - IncomingRunner now logs rejected messages to the vette log.
      (LP: #1068837)

    - The name of the mailmanctl master lock file is now congigurable via the
      mm_cfg.py setting MASTER_LOCK_FILE.  (LP: #1082308)

    - list_lists now has an option to list only lists with public archives.
      (LP: #1082711)

  Contributed programs

    - A new import_majordomo_into_mailman.pl script has been contributed by
      Geoff Mayes.  (LP: #1129742)

    - A new "sitemap" bash script has been contributed by Tomasz Chmielewski
      <mangoo at wpkg.org> to generate a sitemap.xml file of an installation's
      public archives for submission to search engines.


    - A Farsi (Persian) translation has been added thanks to Javad Hoseini and
      Mahyar Moghimi.

    - Fixed several misspelled or garbled string replacements in the Spanish
      message catalog.  (LP: #1160138)

      determined to be truly stale.  (LP: #1189558)

    - It is no longer possible to add 'invalid' addresses to the ban_list
      and the *_these_nonmembers filters from the check boxes on the admindb

    - Changed configure's method for getting Python's include directory from

    - Added an Auto-Generated: header to password reminders.  (LP: #558240)

    - Fixed a bug where non-ascii characters in the real name in a subscription
      request could throw a UnicodeEncodeError upon subscription approval and
      perhaps in other situations too.  (LP: #1047100)

    - The query fragments send_unsub_notifications_to_list_owner and
