Log Message:
Update mailman to 2.1.11

  New Features

    - Added a new cron/cull_bad_shunt script to cull and optionally
      archive old entries from the bad and shunt queues. This is controlled
      by new Defaults.py/mm_cfg.py settings BAD_SHUNT_STALE_AFTER (default
      7 days) and BAD_SHUNT_ARCHIVE_DIRECTORY (default None) which determine
      how long to keep bad and shunt queue entries and optionally, where to
      archive removed entries.

    - Prepended list name to bounce log unrecognized bounce messages.

    - Added a new Defaults.py|mm_cfg.py setting ACCEPTABLE_LISTNAME_CHARACTERS
      with default value '[-+_.=a-z0-9]'.  This Python regular expression
      character class specifies the characters allowed in list names.  The
      motivation for this is the fact that previously, a list named, e.g.,
      xxx&yyy could be created and MTA aliases generated that would cause
      The MTA to execute yyy as a command.  There is a possible security issue
      here, but it is not believed to be exploitable in any meaningful way.

  Bug fixes and other patches

    - Changed the preservation of unparseable messages to be conditional on
      the Defaults.py/mm_cfg.py setting of QRUNNER_SAVE_BAD_MESSAGES and
      changed the queue directory in which messages are preserved from 'shunt'
      to 'bad'.

    - Fixed a bug introduced in 2.1.10 that caused some email subscribe
      requests to be shunted (1966837).

    - Fixed a problem with bin/update erroneously moving templates from
      templates/xx to lists/xx if a list has the same name as a language
      code.  Also fixed the absolute path to lists/ (1418670 ).

    - Changed Utils.ValidateEmail to not allow specials (particularly ':')
      in unquoted local parts (1956393).

    - Changed bin/update to remove .bak files erroneously left behind in
      qfiles/*/ by a 2.1.9 bug.

    - Added 's' to %(listname) in templates/ia/admlogin.html and
      templates/sl/help.txt (1682990).

    - Use newer template variable for site-owner address in
      templates/ko/newlist.txt and templates/ru/newlist.txt (1578766).

    - Corrections to Spanish translation submitted by Wikimedia Foundation
      (1433262) and Debian.

    - Corrections to German translation submitted by Ralf Doeblitz (916196).

    - Correction to French translation submitted by Maxime Carron (1588617).

    - Correction to Portuguese translation submitted by Gabriel P. Silva
      (1733057).

    - Add #! line to fblast.py test script (1578740).

    - Fixed unescaped '%' in templates/nl/newlist.txt (1719017).

    - Changed non-ascii characters in some templates/*/*.html files to HTML
      entities.

    - Fixed a problem in Decorate.py that could result in a multipart
      message with no part headers for the original body part (1991348).

    - Improved recognition of some bounce messages.

    - Rearranged calls to the list setBounceInfo() method in Bouncer.py
      to accommodate MemberAdaptors that store bounce info outside the
      list instance.

    - Fixed CookHeaders.py which in some cases with new style prefixing
      would insert an extra space between the prefix and the subject.

    - Changed OldStyleMemberships.py to remove the member from one_last_digest
      when changing from regular to digest delivery to avoid the possibility
      of a duplicate digest in some circumstances.

    - Patched Danish message catalog for proper use of HTML entities per
      Jonas Smedegaard (1999966).

    - Improved bounce loop detection and handling in BounceRunner.py.

    - Merged the Catalan i18n from the Mailman Catalan Translation Team.

    - German translation updated by Peer Heinlein.

    - Added check for gateway_to_news before holding for ModeratedNewsgroup.

    - At some point, cron/senddigests and bin/update were inadvertently

      de Gastal Morales.

    - Added 'listname' to the replacements for the archidxfoot.html template.
