-*- coding: iso-8859-1 -*- Mailman - The GNU Mailing List Management System Copyright (C) 1998-2015 by the Free Software Foundation, Inc. 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301, USA Here is a history of user visible changes to Mailman. 2.2 Branch Backports (released in conjunction with 2.1.19) The following New Features and Bug Fixes have been in an "unofficial, never to be released" Mailman 2.2 branch for several years. Until now, they were never implemented on the official 2.1 branch because of their i18n impacts. Given that there have been a number of i18n impacting changes due to DMARC mitigations in the last few releases, it has been decided to backport these as well. All of these changes have been running in production on several lists for years without problems other than untranslated strings, so they should be reasonably "bug free". New Features - There is a new list attribute 'subscribe_auto_approval' which is a list of email addresses and regular expressions matching email addresses whose subscriptions are exempt from admin approval. (LP: #266609) - Confirmed member change of address is logged in the 'subscribe' log, and if admin_notify_mchanges is true, a notice is sent to the list owner using a new adminaddrchgack.txt template. - Added an 'automate' option to bin/newlist to send the notice to the admin without the prompt. - The processing of Topics regular expressions has changed. Previously the Topics regexp was compiled in verbose mode but not documented as such which caused some confusion. Also, the documentation indicated that topic keywords could be entered one per line, but these entries were not handled properly. Topics regexps are now compiled in non-verbose mode and multi-line entries are 'ored'. Existing Topics regexps will be converted when the list is updated so they will continue to work. - Added real name display to the web roster. (LP: #266754) Bug fixes and other patches - Changed the response to an invalid confirmation to be more generic. Not all confirmations are subscription requests. - Changed the default nonmember_rejection_notice to be more user friendly. (LP: #418728) - Added "If you are a list member" qualification to some messages from the options login page. (LP: #266442) - Changed the 'Approve' wording in the admindbdetails.html template to 'Accept/Approve' for better agreement with the button labels. - Added '(by thread)' to the previous and next message links in the archive to emphasize that even if you got to the message from a subject, date or author index, previous and next are still by thread. 2.1.19 (xx-xxx-xxxx) New Features - There is a new list attribute dmarc_wrapped_message_text and a DEFAULT_DMARC_WRAPPED_MESSAGE_TEXT setting to set the default for new lists. This text is added to a message which is wrapped because of dmarc_moderation_action in a separate text/plain part that precedes the message/rfc822 part containing the original message. It can be used to provide an explanation of why the message was wrapped or similar info. - There is a new list attribute equivalent_domains and a DEFAULT_EQUIVALENT_DOMAINS setting to set the default for new lists which in turn defaults to the empty string. This provides a way to specify one or more groups of domains, e.g., mac.com, me.com, icloud.com, which are considered equivalent for validating list membership for posting and moderation purposes. - There is a new WEB_HEAD_ADD setting to specify text to be added to the section of Mailman's internally generated web pages. This doesn't apply to pages built from templates, but in those cases, custom templates can be created. (LP: #1409396) - There is a new DEFAULT_SUBSCRIBE_OR_INVITE setting. Set this to Yes to make the default selection on the admin Mass Subscriptions page Invite rather than Subscribe. (LP: #1404511) - There is a new list attribute in the Bounce processing section. bounce_notify_owner_on_bounce_increment if set to Yes will cause Mailman to notify the list owner on every bounce that increments a list member's score but doesn't result in a probe or disable. There is a new configuration setting setting DEFAULT_BOUNCE_NOTIFY_OWNER_ON_BOUNCE_INCREMENT to set the default for new lists. This in turn defaults to No. (LP: #1382150) Changed behavior - Mailman's log files, request.pck files and heldmsg-* files are no longer created world readable to protect against access by untrusted local users. Note that permissions on existing log files won't be changed so if you are concerned about this and don't rotate logs or have a logrotate process that creates new log files instead of letting Mailman create them, you will need to address that. (LP: #1327404) Other changes - The Python Powered logo image has been replaced in the misc/ directory in the source distribution. Depending on how you've installed these images, you may need to copy PythonPowered.png from the misc/ directory in the source or from the $prefix/icons/ installed directory to another location for your web server. (LP: #1408575) i18n - The Russian templates have been updated by Danil Smirnov. (LP: #1403462) - The Japanese translation has been updated by SATOH Fumiyasu. (LP: #1402989) - A minor change in the French translation of a listinfo subscribe form message has been made. (LP: #1331194) Bug fixes and other patches - Fixed a bug in bin/rmlist that would throw an exception or just fail to remove held message files for a list with regexp special characters in its name. (LP:#1414864) - When applying DMARC mitigations, CookHeaders now adds the original From: to Cc: rather than Reply-To: in some cases to make MUA 'reply' and 'reply all' more consistent with the non-DMARC cases. (LP: #1407098) - The Subject: of the list welcome message wasn't always in the user's preferred language. Fixed. (LP: #1400988) - Accept email command in Subject: prefixed with Re: or similar with no intervening space. (LP: #1400200) - Fixed a UnicodeDecodeError that could occur in the web admin interface if 'text' valued attributes have unicode values. (LP: #1397170) - We now catch the NotAMemberError exception thrown if an authenticated unsubscribe is submitted from the user options page for a nonmember. (LP: #1390653) - Fixed an archiving bug that would cause messages with 'Subject: Re:' only to be indexed in the archives without a link to the message. (LP: #1388614) - The vette log entry for a message discarded by a handler now includes the list name and the name of the handler. (LP: #558096) - The options CGI now rejects all but HTTP GET and POST requests. (LP: #1372199) - A list's poster password will now be accepted on an Urgent: header. (LP: #1371678) - Fixed a bug which caused a setting of 2 for REMOVE_DKIM_HEADERS to be ignored. (LP: #1363278) - Renamed messages/sr/readme.sr to README.sr. (LP: #1360616) - Moved the dmarc_moderation_action checks from the Moderate handler to the SpamDetect handler so that the Reject and Discard actions will be done before the message might be held by header_filter_rules, and the Wrap Message and Munge From actions will be done on messages held by header_filter_rules if the message is approved. (LP: #1334450) - tags have been added around most check boxes and radio buttons and their text labels in the admin and admindb web GUI so they can be (de)selected by clicking the text. (LP: #266391) - If checking DNS for dmarc_moderation_action and DNS lookup is not available, log it. (LP: #1324541) - Handle missing From: header addresses for DMARC mitigation actions. (LP: #1318025) 2.1.18-1 (06-May-2014) Bug fixes and other patches - A critical incompatibility between the DMARC Wrap Message action and Python versions older than 2.6.x for some x <= 5 existed and caused Wrapped message to be shunted. This is fixed. (LP: #1316682) - Sender: headers are no longer removed in from_is_list Munge From actions. (LP: #1315970) 2.1.18 (03-May-2014) Acknowledgements - Thanks to Jim Popovitch and Phil Pennock for the branch that formed the basis of the dmarc_moderation_action feature. - Thanks to Franck Martin et al for the branch that formed the basis of the from_is_list feature. Dependencies - There is a new dependency associated with the new Privacy options -> Sender filters -> dmarc_moderation_action feature discussed below. This requires that the dnspython package be available in Python. This package can be downloaded from the above site or from the CheeseShop or installed with pip. New Features - The from_is_list feature introduced in 2.1.16 is now unconditionally available to list owners. There is also, a new Privacy options -> Sender filters -> dmarc_moderation_action feature which applies to list messages where the From: address is in a domain which publishes a DMARC policy of reject or possibly quarantine. This is a list setting with values of Accept, Wrap Message, Munge From, Reject or Discard. There is a new DEFAULT_DMARC_MODERATION_ACTION configuration setting to set the default for this, and the list admin UI is not able to set an action which is 'less' than the default. The prior ALLOW_FROM_IS_LIST setting has been removed and is effectively always Yes. There is a new dmarc_quarantine_moderation_action list setting with default set by a new DEFAULT_DMARC_QUARANTINE_MODERATION_ACTION configuration setting which in turn defaults to Yes. The list setting can be set to No to exclude domains with DMARC policy of quarantine from dmarc_moderation_action. dmarc_moderation_action and from_is_list interact in the following way. If the message is From: a domain to which dmarc_moderation_action applies and if dmarc_moderation_action is other than Accept, dmarc_moderation_action applies to that message. Otherwise the from_is_list action applies. Also associated with dmarc_moderation_action are configuration settings DMARC_RESOLVER_TIMEOUT and DMARC_RESOLVER_LIFETIME. These are described in more detail in Defaults.py. There are also new vette log entries written when dmarc_moderation_action is found to apply to a post. i18n - Added missing tag to French listinfo template. (LP: #1275964) Bug Fixes and other patches - Removed HTML tags from the title of a couple of rmlist.py pages because browsers don't render tags in the title. (LP: #265848) - Most Mailman generated notices to list owners and moderators are now sent as Precedence: list instead of bulk. (LP: #1313146) - The Reply-To: munging options weren't honored if there was no from_is_list action. (LP: #1313010) - Changed from_is_list actions to insert the list address in Cc: if the list is fully personalized. Otherwise, the list address is only in From: and Reply-To: overrides it. (LP: #1312970) - Fixed the Munge From action to only Munge the From: and/or Reply-To: in the outgoing message and not in archives, digests and messages sent via the usenet gateway. (LP: #1311431) - Fixed a long standing issue in which a notice sent to a user whose language is other than that of the list can cause subsequent things which should be in the list's language to be in the user's language instead. (LP: #1308655) - Fixed the admin Membership List so a search string if any is not lost when visiting subsequent fragments of a chunked list. (LP: #1307454) - For from_is_list feature, use email address from original From: if original From: has no display name and strip domain part from resultant names that look like email addresses. (LP: #1304511) - Added the list name to the vette log "held message approved" entry. (LP: 1295875) - Added the CGI module name to various "No such list" error log entries. (LP: 1295875) - Modified contrib/mmdsr to report module name if present in "No such list error log entries. - Fixed a NameError exception in cron/nightly_gzip when it tries to print the usage message. (LP: #1291038) - Fixed a bug in ListAdmin._handlepost that would crash when trying to preserve a held message for the site admin if HOLD_MESSAGES_AS_PICKLES is False. (LP: #1282365) - The from_is_list header munging feature introduced in Mailman 2.1.16 is no longer erroneously applied to Mailman generated notices. (LP: #1279667) - Changed the message from the confirm CGI to not indicate approval is required for an acceptance of an invitation. (LP: #1277744) - Fixed POSTFIX_STYLE_VIRTUAL_DOMAINS to be case-insensitiive. (LP: #1267003) - Added recognition for another simple warning to bounce processing. (LP: #1263247) - Fixed a few failing tests in tests/test_handlers.py. (LP: #1262950) - Fixed bin/arch to not create scrubbed attachments for messages skipped when processing the --start= option. (LP: #1260883) - Fixed email address validation to do a bit better in obscure cases. (LP: #1258703) - Fixed a bug which caused some authentication cookies to expire too soon if AUTHENTICATION_COOKIE_LIFETIME is non-zero. (LP: #1257112) - Fixed a possible TypeError in bin/sync_members introduced in 2.1.17. (LP: #1243343) Miscellaneous - Added to the contrib directory, a script from Alain Williams to count posts in a list's archive. 2.1.17 (23-Nov-2013) New Features - Handling of posts gated from usenet to a list via the Mail <-> News gateway is changed. Formerly, no list membership, moderation or *_these_nonmembers checks were done. Now, if the sender of the usenet post is a moderated member or a nonmember matching a *_these_nonmembers filter, those checks will be done and actions applied. Nonmember posts from senders not matching a *_these_nonmembers filter are still accepted as before. (LP: #1252575) - There is a new mm_cfg.py setting ANONYMOUS_LIST_KEEP_HEADERS. Since it is not possible to know which non-standard headers in a message might reveal sender information, we now remove all headers from incoming posts to anonymous lists except those which match regular expressions in this list. The default setting keeps non X- headers except those known to reveal sender information, Mailman added X- headers and x-Spam- headers. See the description in Defaults.py for more information. (LP: #1246039) i18n - The Japanese message catalog has been updated by SATOH Fumiyasu. (LP: #1248855) Bug Fixes and other patches - Added a reopen command to the sample init.d script in misc/mailman.in. (LP: #1251917) - Fixed a misspelling in Tagger.py causing an "unexpected keyword argument 'Delete'" exception. (LP: #1251495) - Fixed contrib/qmail-to-mailman.py to work with a user other than 'mailman' and to recognize more listname-* addresses. (LP: #412293) - Fixed a possible UnicodeDecodeError in bin/sync_members. (LP: #1243343) - Fixed Makefile to not include $DESTDIR in paths compiled into .pyc files for traceback purposes. (LP: #1241770) 2.1.16 (16-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@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 to generate a sitemap.xml file of an installation's public archives for submission to search engines. i18n - The Danish translation has been updated thanks to Tom Christensen. - Fixed a string in the Czech message catalog. (LP: #1234567) - 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) - pt_BR message catalog has two new and an updated message per Hugo Koji Kobayashi. (LP: #1138578) - German message catalog has been updated per Ralf Hildebrandt. - Corrected typo in templates/it/private.html. Bug Fixes and other patches - Fixed a crash in SpamDetect.py which caused messages with unparseable RFC 2047 encoded headers to be shunted. (LP: #1235101) - Fixed cron/disabled to send a fresh cookie when notifying disabled members. (LP: #1203200) - Added "message_id" to the interpolation dictionary for the Article.html template. (LP: #725498) - Changed the admin GUI to report only the bad entries in a list of email addresses if any are bad. (LP: #558253) - Added logging for template errors in HyperArch.py. (LP: #558254) - Added more explanation to the bad owner address message from bin/newlist. (LP: #1200763) - Fixed a bug causing the admin web interface to fail CSRF checking if the list name contains a '+' character. (LP: #1190802) - Fixed bin/mailmanctl -s to not remove the master lock if it can't be 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 interface. (LP: #1187201) - Backported recognition for mail.ru DSNs and minor bug fixes from lp:flufl.bounce. (LP: #1074592, LP: #1079249 and #1079254) - Defended against buggy web servers that don't include an empty QUERY_STRING in the CGI environment. (LP: #1160647) - The Switchboard.finish() method now logs the text of the exception when it fails to unlink/preserve a .bak file. (LP: #1165589) - The pending (un)subscriptions waiting approval are now sorted by email address in the admindb interface as intended. (LP: #1164160) - The subscribe log entry for a bin/add_members subscribe now identifies bin/add_members as the source. (LP: #1161642) - Fixed a bug where the Subject: of the user notification of a bin/remove_members unsubscribe was not in the user's language. (LP: #1161445) - Fixed a bug where BounceRunner could create and leave behind zero length bounce-events files. (LP: #1161610) - Added recognition for another Yahoo bounce format. (LP: #1157961) - Changed configure's method for getting Python's include directory from distutils.sysconfig.get_config_var('CONFINCLUDEPY') to distutils.sysconfig.get_python_inc(). (LP: #1098162) - 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 send_unsub_ack_to_this_batch will now assume default values if not set in mass unsubscribe URLs. (LP: #1032378) - Replaced utf-8 encoded characters in newly added German templates with HTML entities. (LP: #1018208) 2.1.15 (13-Jun-2012) Security - Strengthened the validation of email addresses. - An XSS vulnerability, CVE-2011-0707, has been fixed. - The web admin interface has been hardened against CSRF attacks by adding a hidden, encrypted token with a time stamp to form submissions and not accepting authentication by cookie if the token is missing, invalid or older than the new mm_cfg.py setting FORM_LIFETIME which defaults to one hour. Posthumous thanks go to Tokio Kikuchi for this implementation which is only one of his many contributions to Mailman prior to his death from cancer on 14 January 2012. New Features - Added a password reminder button to the private archive login page. Backported from the 2.2 branch. - There is a new list attribute regular_exclude_ignore set from mm_cfg.py DEFAULT_REGULAR_EXCLUDE_IGNORE. This defaults to True even though the prior behavior is equivalent to False. A True setting will ignore an exclude list if the poster is not a member of that list. The False setting can result in list members not receiving posts if the nonmember post is not accepted by the exclude list. Backported from 2.2 branch. - Eliminated the list cache from the qrunners. Indirect self-references caused lists to never be dropped from the cache which in turn caused the qrunners to grow very large in installations with many lists or multiple large lists. Bug #862683. - The user options 'list my other subscriptions' page now indicates for each list if the subscription is 'nomail' or 'digest'. Bug #793669. - A new list poster password has been implemented. This password may only be used in Approved: or X-Approved: headers for pre-approving posts. Using this password for that purpose precludes compromise of a more valuable password sent in plain text email. Bug #770581. - A new mm_cfg.py setting AUTHENTICATION_COOKIE_LIFETIME has been added. If this is set to a non-zero value, web authentication cookies will expire that many seconds following their last use. Its default value is zero to preserve current behavior. - A new mm_cfg.py setting RESPONSE_INCLUDE_LEVEL has been added to control how much of the original message is included in automatic responses to email commands. The default is 2 to preserve the prior behavior of including the full message. Setting this to 1 in mm_cfg.py will include only the original headers, and 0 will include none of the original. It is recommended to set this to 0 in mm_cfg.py to minimize the effects of backscatter. Bug #265835. - A new mm_cfg.py setting DEFAULT_RESPOND_TO_POST_REQUESTS has been added to control the default for respond_to_post_requests for new lists. It is set to Yes for backwards compatibility, but it is recommended that serious consideration be given to setting it to No. Bug #266051. - A new mm_cfg.py setting DISCARD_MESSAGE_WITH_NO_COMMAND has been added to control whether a message to the -request address without any commands or a message to -confirm whose To: address doesn't match VERP_CONFIRM_REGEXP is responded to or just logged. It defaults to Yes which is different from prior behavior. Bug #410236. - Two new mm_cfg.py settings, BROKEN_BROWSER_WORKAROUND and BROKEN_BROWSER_REPLACEMENTS, have been added to control escaping of additional characters beyond the standard <, >, &, and " in the web UI. See the documentation of these settings in Defaults.py. The default values for these settings result in no change from the prior release. Bug #774588. i18n - Added some missing German templates from Egon Frerich. - Added Greek translation from Antonis Limperis. - A few errors in the Basque translation are fixed. Bug #836861. - Fixed a misspelling in the German invite.txt template. Bug #815444. - Fixed a missing format character in the Spanish translation. Bug #670988. - Thanks go to the following for updating translations for the changes in this release. Thijs Kinkhorst Stefan F�rster Fabian Wenk Bug Fixes and other patches - Fixed a bug that could send an admin notice of a held subscription with the subject in the user's preferred language instead of the list's preferred language and possibly not properly RFC 2047 encoded. (LP: #998949) - Fixed a possible CPU bound loop in OutgoingRunner if the attempt to Connect to the SMTP server throws a socket.error. (LP: #966531) - Fixed a potential crash in the web UI if a language is removed from the LC_DESCRIPTIONS dictionary. (LP: #966565) - Added an Auto-Submitted: header to invitations and (un)subscription confirmation requests to reduce the possibility of an autoresponder confirming the request. (LP: #265831) - Added javascript to the private.html and admlogin.html templates to focus the cursor on the entry field. (LP: #266054) - Added CPPFLAGS and LDFLAGS to src/Makefile to support their use. (LP: #637652) - Stopped removing the trailing slash from the List-Archive: header URL. (LP: #964190) - A configured version of contrib/courier-to-mailman.py is now created in build/contrib/courier-to-mailman.py. (LP: #999250) - Subscription disabled warnings are now sent without a Precedence: header. Bug #808821. - Backported 2.2 branch fix for a problem in SpamDetect.py that could cause header_filter_rules to fail to match RFC 2047 encoded headers. - Fix for bug #629738 could cause a crash in the admindb details display if the decoded message body contained characters not in the character set of the list's preferred language. Fixed. Bug #910440. - Added recognition for another Qmail bounce format. - Fixed an erroneous seek in the Mailman.Mailbox.Mailbox.AppendMessage method that could cause a corrupt mailbox for files opened 'w+'. Bug #901957. - A held message with a null sender caused a crash in the admindb interface. This is fixed by changing the sender to . Bug #897103. - Changed subject prefixing to allow for possible whitespace between an 'Re' and the following colon when determining how to add the prefix. Bug #893290. - Fixed a problem where topics regexps would not match RFC 2047 encoded Keywords: and/or Subject: headers. Bug #891676. - Fixed misleading response to an email approval of a held message. Bug #889968. - Added masthead.txt to the list of templates that can be edited via the web admin interface. Bug #266805. - Changed the way digest_footer is added to the RFC 1153 (plain) format digest for RFC compliance. Bug #887610. - Fixed cron/checkdbs to report unsubscriptions waiting approval. Bug #873821. - The fix for BUG #266220 (sf1181161) has been enhanced so that if there is a pathological HTML part such that the Approved: password text isn't found, but it is found after stripping out HTML tags, the post is rejected with an informative message. - A bug that would cause reset of any new_member_options bits other than the four displayed as checkboxes on the list admin General Options page whenever the page was updated or bin/config_list attempted to update new_member_options has been fixed. Bug #865825. - A problem with the logic avoiding unnecessarily reloading a current list object from the config.pck arises if the list is updated by another process within the same second that it was last read/written. That can cause the reading of latest version of the list to be skipped. This has been fixed. Bug #862675. - Fixed bin/export.py to accept case insensitive password schemes. Bug #833134. - Added Tokio Kikuchi's icons to the misc/ and installed icons/ directories. Bug #782474. - Fixed a problem which could result in raw, undecoded message bodies appearing in plain digests and archives. Bug #787790. - Fixed a problem in admindb.py where the character set for the display of the message body excerpt was not correctly determined. Bug #779751. - Prevented setting user passwords with leading/trailing whitespace. Bug #778088. - Mailman now sets the 'secure' flag in cookies set via https URLs. Bug #770377. - Added a logout link to the admindb interface and made both admin and admindb logout effective for a site admin cookie if allowed. Bug #769318. - Replaced the old Mailman logos and icon that install to Mailman's icons directory with the new ones. If you copy these elsewhere on your server, please copy these new ones. - Changed bin/genaliases to only call the POSTFIX_*_CMD commands once when MTA = 'Postfix'. Bug #266408. - Added a report of the affected members to the warnings issued when setting a list with digest members digestable=No and when setting a list with non-digest members nondigestable=no. Bug #761232. - Fixed a problem where content filtering could remove the headers from an attached message/rfc822 part if the message in that part is multipart/alternative and collapse_alternatives is Yes. Bug #757062. - Changed the subscribe CGI to strip leading and trailing whitespace from the supplied email address. Bug #745432. - Changed the maximum number of arguments for the who command to be considered administrivia from 2 to 1 to help avoid false positives. Bug #739524. - Added the list name as 'display-name' in added Sender: headers to help mitigate Outlook et al 'on behalf of' displays. Bug #736849. - Fixed a typo in the usage() definition cron/gate_news. Bug #721015. - Fixed an uncaught KeyError when poster tries to cancel a post which was already handled. Bug #266224. - Held message user notifications now come From: list-owner instead of list-bounces. Bug #714424. - Issue an HTTP 404 status for private archive file not found. - @listname entries in *_these_nonmembers are no longer case sensitive. Bug #705715. - Changed bin/rmlist to also remove heldmsg files for the removed list and fixed a problem with removal of stale locks for the list. Bug #700528. - Fixed a bug where content filtering could leave a multipart message or part with just one sub-part. These should be recast to just the sub-part. Bug #701558. - Fixed a bug that could erroneously handle posts from addresses in *_these_nonmembers and send held/rejected notices to bogus addresses when The From or other sender header is RFC 2047 encoded. Bug #702516. - Updated contrib/mm-handler-2.1.10 to better handle lists with names that look like admin addresses. Bug #697161. - Added bounce recognition for a bogus Dovecot MDN. Bug #693134. - Fixed a problem where an emailed command in the Subject: header with a non-ascii l10n of an 'Re:' prefix is ignored. Bug #685261. - Fixed a problem with approving a post by email when the body of the approval mail is base64 encoded. Bug #677115. - Fixed the host name in the From: address of the owner notification from bin/add_members. Bug #666181. 2.1.14 (20-Sep-2010) Security - Two potential XSS vulnerabilities have been identified and fixed. New Features - A new feature for controlling the addition/replacement of the Sender: header in outgoing mail has been implemented. This allows a list owner to set include_sender_header on the list's General Options page in the admin GUI. The default for this setting is Yes which preserves the prior behavior of removing any pre-existing Sender: and setting it to the list's -bounces address. Setting this to No stops Mailman from adding or modifying the Sender: at all. Additionally, there is a new Defaults.py/mm_cfg.py setting ALLOW_SENDER_OVERRIDES which defaults to Yes but which can be set to No to remove the include_sender_header setting from General Options, and thus preserve the prior behavior completely. - Bounce processing has been enhanced so that if a bounce is returned to a list from a non-member who is a member of a regular_include_list, the bounce will be processed as a bounce for the included list. i18n - Fixed a missing format character in the German bin/mailmanctl docstring. - Updated Dutch translation from Jan Veuger. - Updated Japanese Translation from Tokio Kikuchi. - Updated Finnish translation from Joni T�yryl�. - Made a few corrections to some Polish templates. Bug #566731. - Made a minor change to the Chinese (China) message catalog. Bug #545772. - Changed a few DOCTYPE directives in templates for compliance. Bug #500952 and Bug #500955. Bug Fixes and other patches - Made minor wording improvements and typo corrections in some messages. Bug #426979. - Fixed i18n._() to catch exceptions due to bad formats. Bug #632660. - Fixed admindb interface to decode base64 and quoted-printable encoded message body excerpts for display. Bug #629738. - Fixed web CGI tracebacks to properly report sys.path. Bug #615114. - Changed the member options login page unsubscribe request to include the requesters IP address in the confirmation request. Bug #610527. - Changed fix_url to lock the list if not locked. Bug #610364. - Made a minor change to the English subscribeack.txt (welcome message) template to emphasize that a password is only required to unsubscribe *without confirmation*. - Fixed an issue in admindb that could result in a KeyError and "we hit a bug" response when a moderator acts on a post that had been handled by someone else after the first moderator had retrieved it. Bug #598671. - Fixed a bug which would fail to show a list on the admin and listinfo overview pages if its web_page_url contained a :port. Bug # 597741. - Fixed bin/genaliases to not throw TypeError when MTA = None. Bug #587657. - Provided the ability to specify in mm_cfg.py a local domain (e.g. 'localhost') for the local addresses in the generated virtual-mailman when MTA = 'Postfix'. See VIRTUAL_MAILMAN_LOCAL_DOMAIN in Defaults.py. Bug #328907. - Made a minor change to the removal of an Approved: pseudo-header from a text/html alternative to allow for an inserted '\xA0' before the password. - Fixed Content Filtering collapse_alternatives to work on deeply nested multipart/alternative parts. Bug #576675. - We now accept/remove X-Approved: and X-Approve: headers in addition to Approved: and Approve: for pre-approving posts. Bug #557750. - Reordered the 'cancel' and 'subscribe' buttons on the subscription confirmation web page so the default action upon 'enter' will be the subscribe button in browsers that pick the first button.

Bug #533468. - Added a traceback to the log message produced when processing the digest.mbox throws an exception. - Added a urlhost argument to the MailList.MailList.Create() method to allow bin/newlist and the the create CGI to pass urlhost so the host will be correct in the listinfo link on the emptyarchive page. Bug #529100. - Added the List-Post header to the default list of headers retained in messages in the MIME digest. Bug #526143. - When daemonizing mailmanctl, we now ensure terminal files are closed. - Fixed a bug in pipermail archiving that caused fallback threading by subject to fail. Bug #266572. - We now give an HTTP 401 status for authentication failures from admin, admindb, private, options and roster CGIs, and an HTTP 404 status from all the CGIs for an invalid list name. - Backported the listinfo template change from the 2.2 branch to fix Bug #514050. - Fixed a bug where going to an archives/private/list.mbox/list.mbox URL would result in a munged URL if authentication was required. Bug #266164. - Fixed a bug where check_perms would throw an OSError if an entry in Mailman's lists/ directory was not a directory. Bug #265613. - Fixed a bug where a message with an Approved: header held by a handler that precedes Approve (SpamDetect by default) would not have the Approved: header removed if the held message was approved.

Bug Fixes and other patches - Added "white-space: pre-wrap" style for

 tag in archives.
      Bug #266467.

    - Added vette logging for rejected and discarded (un)subscribe requests.

    - Fixed a bug in admindb.py that could erroneously discard an unsubscribe
      request as a duplicate.

    - Decoded RFC 2047 encoded message subjects for a few reports.
      Bug #266428.

    - Fixed the French, Spanish and Hebrew translations which improperly
      translated the 'coding:' line in bin/config_list output.

    - Fixed the auto-responder to treat messages to -confirm, -join, -leave,
      -subscribe and -unsubscribe as requests rather than posts.  Bug #427962.

    - Configure/make no longer builds Japanese and Korean codecs in
      pythonlib if Python already has them.

    - Inadvertently setting a null site or list password allowed access
      to a list's web admin interface without authentication.  Fixed by
      not accepting null passwords.

    - Changed VERP_CONFIRM_REGEXP  in Defaults.py to work if the replying
      MUA folds the To: header and in cases where the list name includes '+'.

    - Fixed some paths in contrib/check_perms_grsecurity.py. Bug #411192.

    - Replies to commands sent to list-request now come From: list-owner
      instead of list-bounces.

    - Mailman no longer folds long sub-part headers in multipart messages.
      In addition, Mailman no longer escapes From_ lines in the body of
      messages sent to regular list members, although MTA's may do it anyway.
      This is to avoid breaking signatures per Bug #265967.

    - XSS protection in the web interface went too far in escaping HTML
      entities.  Fixed.

    - Removed or anonymized additional headers in posts to anonymous lists.

    - Fixed a bug that could cause incorrect threading of replies to archived
      messages that arrive with timestamps in the same second.

    - Scrubbed HTML attachments containing tab characters would get the tabs
      replaced by a string of ' ' without a semicolon.  Fixed.

    - Caught a TypeError in content filtering, collapse alternatives that
      occurred with a malformed message if a multipart/alternative part
      wasn't multi-part.  Reported in comments to bug #266230.

    - Fixed a few things in bin/update:
      - Changed some old messages for more current meaning.
      - Fixed qfiles update to not lose metadata from 2.1.5+ format entries.
      - Fixed 2.0.x template migration to not die if the templates/ tree
        contains subdirectories from a version control system.

    - Fixed a bug that would show a list on the admin and listinfo overview
      pages if its web_page_url host contained the current host as a
      substring.  Bug #342162.

    - Fixed a bug in Utils.canonstr() that would throw a UnicodeDecodeError
      if the string contained an HTML entity > 255 and also characters in the
      128-255 range.  Bug #341594.

    - Added recognition for more bounces.

    - Updated contrib/mmdsr to report preserved messages and to use mktemp to
      create temp files.

2.1.12 (23-Feb-2009)

  Bug fixes and other patches

    - Fix compatibility with Python 2.6.

    - Fixed a bug in admin.py which would result in chunked pages of the
      membership list for members whose address begins with a non-alphanumeric
      character to not be visible or retrievable.

    - Changed ListAdmin.py to make rejected post messages From: the -owner
      address instead of the -bounces address.

    - With MTA = 'Postfix', if the STANZA END for a list being removed is
      missing or munged, the remainder of the aliases and/or virtual-mailman
      file is lost.  Fixed.

    - Since Mailman 2.1.1, 2.0.x outstanding subscription and held message
      requests have not been migrated properly.  This is fixed.
      Bug #266106 (sf998384).

    - Changed cron/gate_news to continue processing the remaining lists on
      certain errors that can be caused by configuration of a particular list.
      Bug #265941 (sf775100).

    - Fixed a bug in AvoidDuplicates.py that caused it to fail if the address
      in the To: or Cc: header differed in case from the case-preserved member
      address.  Bug #297795.

    - Fixed a problem in SecurityManager that caused it to not find the
      cookie when CheckCookie was not given a user and the user in the cookie
      had a %xx encoded character.  Bug # 299220.

    - Fixed a minor fromusenet reporting issue in the contributed mmdsr
      script.

    - Fixed a minor issue in cron/gate_news that could cause a list's
      watermark to not be completely updated.

    - Fixed an issue that prevented editing the options.html template from
      the web admin interface. SF Bug #2164798.

    - Fixed a problem in Decorate which could throw a TypeError on conversion
      to unicode of a header/footer that was already unicode because of
      interpolating a unicode value.

    - Fixed an issue where list creation would report bad owner email
      instead of bad listname when the list name had non-ascii characters.
      SF Bug #2126489.

    - Fixed an issue where in some circumstances HyperArch.py would translate
      ' at ' into the wrong language ultimately throwing a UnicodeDecodeError
      when the translation was decoded with a different character set.
      Bug #308152.

    - Corrected a typo in Mailman/Gui/Privacy.py. Bug #309757.

    - Changed the pattern used to recognize URLs in messages for the pipermail
      archive in order to try to do a better job of making hyperlinks.
      Bug #310124.

    - Added missing --bare option to French translation of list_lists help.
      Bug #312119.

    - Fixed a long standing error that stopped relative hrefs from being
      generated for links on Mailman's web pages.

    - Changed the admindb interface so that when messages are rejected from
      the summary page, the reject reason is the rejection message from the
      Errors.HoldMessage subclass instead of the generic "No reason given".

    - Fixed the admin Membership List Find member function so the 'letter'
      links to a chunked result would still be limited to the Find member
      search. SF patch #1532081.

    - Changed scripts/driver to return a 405 status for non GET, POST, HEAD
      methods. SF patch #1578756.

    - Fixed a bug in admindb.py in the implementation of replacing "No Reason
      Given" with the default rejection reason.  Bug #325016.

    - Changed Gui/Topics.py to validate regexps in VERBOSE mode.  Bug #327008.

    - Worked around a potential problem in HyperArch.py with unicode character
      set arguments.  Bug #328353.

    - Recognize a couple more bounces.

    - Fixed a bug introduced in 2.1.11 which would attempt to store bounce info
      for a member just deleted if bounce_you_are_disabled_warnings is zero.

  i18n

    - Updated Dutch, Catalan and Polish translations.

  Miscellaneous

    - Added Lindsay Haisley's courier_to_mailman.py to the contrib directory.

    - Added John Dennis' (RedHat) FHS patch to the contrib directory.

2.1.11 (30-Jun-2008)

  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
      'preconfigured'. This has been fixed.

    - Brazilian Portuguese translation updated by Diego Francisco
      de Gastal Morales.

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

  Miscellaneous

    - Brad Knowles' mailman daily status report script updated to 0.0.18.

2.1.10 (21-Apr-2008)

  Security

    - The 2.1.9 fixes for CVE-2006-3636 were not complete.  In particular,
      some potential cross-site scripting attacks were not detected in
      editing templates and updating the list's info attribute via the web
      admin interface.  This has been assigned CVE-2008-0564 and has been
      fixed.  Thanks again to Moritz Naumann for assistance with this.

    - There is a new mm_cfg.py/Defaults.py variable
      OWNERS_CAN_CHANGE_MEMBER_PASSWORDS which controls whether the list
      owner can change a member's password from the member's options page.
      This defaults to No and should be changed to Yes only if list owners
      are trusted to not change a member's password, log in as the member
      and make global membership changes.

  New Features

    - Changed cmd_who.py to list all members if authorization is with the
      list's admin or moderator password and to accept the password if the
      roster is public.  Also changed the web roster to show hidden members
      when authorization is by site or list's admin or moderator password
      (1587651).

    - Added the ability to put a list name in accept_these_nonmembers
      to accept posts from members of that list (1220144).

    - Added a new 'sibling list' feature to exclude members of another list
      from receiving a post from this list if the other list is in the To: or
      Cc: of the post or to include members of the other list if that list is
      not in the To: or Cc: of the post (Patch ID 1347962).

    - Added the admin_member_chunksize attribute to the admin General Options
      interface (Bug 1072002, Partial RFE 782436).

Internationalization

    - Added the Hebrew translation from Dov Zamir.  This includes addition of
      a direction ('ltr', 'rtl') to the LC_DESCRIPTIONS table.  The
      add_language() function defaults direction to 'ltr' to not break
      existing mm_cfg.py files.

    - Added the Slovak translation from Martin Matuska.

    - Added the Galician translation from Frco. Javier Rial Rodr�guez.

  Bug fixes and other patches

    - Added bounce recognition for several additional bounce formats.

    - Fixed CommandRunner.py to decode a quoted-printable or base64 encoded
      message part (1829061).

    - Fixed Scrubber.py to avoid loss of an implicit text/plain message part
      with no Content-* headers in a MIME multipart message (759841).  Fixed
      several other minor scrubber issues (1242450).

    - Added Date and Message-ID headers to the confirm reply message that
      Mailman adds to the admin notification (1471318).

    - Fixed Cgi/options.py to not present the "empty" topic to user.

    - Fixed Handlers/CalcRecips.py to not process topics if topics are
      disabled for the list.  This caused users who had previously subscribed
      to topics and elected to not receive non-matching posts to receive no
      messages after topics were disabled for the list.

    - Fixed MaildirRunner.py to handle hyphenated list names.

    - Fixed a bug in MimeDel.py (content filtering) which caused
      *_filename_extensions to not match if the extension in the message was
      not all lower case.

    - Fixed versions.py to not call a non-existant method when converting held
      posts from Mailman 1.0.x lists.

    - Added a test to configure to detect a missing python-devel package on
      some RedHat systems.

    - Fixed bin/dumpdb to once again be able to dump marshals (broken since
      2.1.5) (963137).

    - Worked around a bug in the Python email library that could cause Mailman
      to not get the correct value for the sender of a message from an RFC
      2231 encoded header causing spurious held messages.

    - Fixed bin/check_perms to detect certain missing permissions on the
      archives/private/ and archives/private//database/ directories.

    - Improved exception handling in cron/senddigests.

    - Changed the admindb page to not show the "Discard all messages marked
      Defer" checkbox when there are only (un)subscribes and no held messages.
      Also added a separator and heading for "Held Messages" like the ones for
      "Subscribe Requests" and "Unsubscribe Requests".  Suppressed the
      "Database Updated" message when coming from the login page.  Also
      removed the "Discard all messages marked Defer" checkbox from the
      details page where it didn't work (1562922, 1000699).

    - Fixed admin.py so null VARHELP category is handled (1573393).

    - Fixed OldStyleMemberships.py to preserve delivery statuses BYADMIN
      and BYUSER on a straight change of address (1642388).  Also fixed a
      bug that could result in a member key with uppercase in the domain.

    - Fixed bin/withlist so that -r can take a full package path to a
      callable.

    - Removal of DomainKey/DKIM signatures is now controlled by Defaults.py
      mm_cfg.py variable REMOVE_DKIM_HEADERS (default = No).  Also, if
      REMOVE_DKIM_HEADERS = Yes, an Authentication-Results: header will be
      removed if present.

    - The DeprecationWarning issued by Python 2.5 regarding string exceptions
      is supressed.

    - format=flowed and delsp=yes are now preserved for message bodies when
      message headers/footers are added and attachments are scrubbed
      (1495122).

    - Queue runner processing is improved to log and preserve for analysis in
      the shunt queue certain bad queue entries that were previously logged
      but lost.  Also, entries are preserved when an attempt to shunt throws
      an exception (1656289).

    - The admin Membership List pages have been changed in that the email
      address which forms a part of the various CGI data keys is now
      urllib.quote()ed. This allows changing options for and unsubbing an
      address which contains a double-quote character, but it may require
      changes to scripts that screen-scrape the web admin interface to
      produce a membership list so they will report an unquoted address.

    - The fix for bug 1181161 in 2.1.7 was incomplete.  The Approve(d): line
      wasn't always found in quoted-printable encoded parts and was never
      found in base64 encoded parts.  This is now fixed.

    - Fixed a mail loop if a list owner puts the list's -bounces or -admin
      address in the list's owner attribute (1834569).

    - Fixed the mailto: link in archived messages to prefix the subject with
      Re: and to put the correct message-id in In-Reply-To (1621278, 1834281).

    - Coerced list name arguments to lower case in the change_pw, inject,
      list_admins and list_owners command line tools (patch 1842412).

    - Fixed cron/disabled to test if bounce info is stale before disabling
      a member when the threshold has been reduced.

    - It wasn't noted here, but in 2.1.9, queue runner processing was made
      more robust by making backups of queue entries when they were dequeued
      so they could be recovered in the event of a system failure.  This
      opened the possibility that if a message itself caused a runner to
      crash, a loop could result that would endlessly reprocess the message.
      This has now been fixed by adding a dequeue count to the entry and
      moving the entry aside and logging the fact after the third dequeue of
      the same entry.

    - Fixed the command line scripts add_members, sync_members and
      clone_member to properly handle banned addresses (1904737).

    - Fixed bin/newlist to add the list's preferred language to the list's
      available_languages if it is other than the server's default language
      (1906368).

    - Changed the first URL in the RFC 2369 List-Unsubscribe: header to go
      to the options login page instead of the listinfo page.

    - Changed the options login page to not issue the "No address given" error
      when coming from the List-Unsubscribe and other direct links.  Also
      changed to remember the user's language selection when redisplaying the
      page following an error.

    - Changed cmd_subscribe.py to properly accept (no)digest without a
      password and to recognize (no)digest and address= case insensitively.

    - Fixed a problem where GuiBase._getValidValue() would truncate a
      floating point Number type to an int if the value was a float instead
      of a numeric string. This affected setting floating point values with
      config_list.

  Miscellaneous

    - Brad Knowles' mailman daily status report script updated to 0.0.17.

    - An updated mm-handler (mm-handler-2.1.10) that can help reduce
      backscatter has been added to the contrib directory.

2.1.9 (12-Sep-2006)

  Security

    - A malicious user could visit a specially crafted URI and inject an
      apparent log message into Mailman's error log which might induce an
      unsuspecting administrator to visit a phishing site.  This has been
      blocked.  Thanks to Moritz Naumann for its discovery.

    - Fixed denial of service attack which can be caused by some
      standards-breaking RFC 2231 formatted headers.  CVE-2006-2941.

    - Several cross-site scripting issues have been fixed.  Thanks to Moritz
      Naumann for their discovery.  CVE-2006-3636

    - Fixed an unexploitable format string vulnerability.  Discovery and fix
      by Karl Chen.  Analysis of non-exploitability by Martin 'Joey' Schulze.
      Also thanks go to Lionel Elie Mamane.  CVE-2006-2191.

  Internationalization

    - New languages: Arabic, Vietnamese.

  Bug fixes and other patches

    - Fixed Decorate.py so that characters in message header/footer which
      are not in the character set of the list's language are ignored rather
      than causing shunted messages (1507248).

    - Switchboard.py - Closed very tiny holes at the upper ends of queue
      slices that could result in unprocessable queue entries.  Improved FIFO
      processing when two queue entries have the same timestamp.

2.1.8 (15-Apr-2006)

  Security

    - A cross-site scripting hole in the private archive script of 2.1.7
      has been closed.  Thanks to Moritz Naumann for its discovery.

  Bug fixes and other patches

    - Bouncers support added: 'unknown user', Microsoft SMTPSVC, Prodigy.net
      and several others.

    - Updated email library to 2.5.7 which will encode payload into qp/base64
      upon setting.  This enabled backing out the scrubber related patches
      including 'X-Mailman-Scrubbed' header in 2.1.7.

    - Fix SpamDetect.py potential hold/reject loop problem.

    - A warning message from email package to the stderr can cause error
      in Logging because stderr may be detached from the process during
      the qrunner run.  We chose not to output errors to stderr but to
      the logs/error if the process is running under mailmanctl subprocess.

    - DKIM header cleansing was separated from Cleanse.py and added to
      -owner messages too.

    - Fixes: Lose Topics when go directly to topics URL (1194419).
      UnicodeError running bin/arch (1395683).  edithtml.py missing import
      (1400128).  Bad escape in cleanarch.  Wrong timezone in list archive
      index pages (1433673).  bin/arch fails with TypeError (1430236).
      Subscription fails with some Language combinations (1435722).
      Postfix delayed notification not recognized (863989).  2.1.7 (VERP)
      mistakes delay notice for bounce (1421285).  show_qfiles: 'str'
      object has no attribute 'as_string' (1444447).  Utils.get_domain()
      wrong if VIRTUAL_HOST_OVERVIEW off (1275856).

  Miscellaneous

    - Brad Knowles' mailman daily status report script updated to 0.0.16.

2.1.7 (31-Dec-2005)

  Security

    - The fix for CAN-2005-0202 has been enhanced to issue an appropriate
      message instead of just quietly dropping ./ and ../ from URLs.

    - A note on CVE-2005-3573: Although the RFC2231 bug example in the CVE has
      been solved in Mailman 2.1.6, there may be more cases where
      ToDigest.send_digests() can block regular delivery.  We put the
      send_digests() calling part in a try/except clause and leave a message
      in the error log if something happened in send_digests().  Daily call of
      cron/senddigests will provide more detail to the site administrator.

    - List administrators can no longer change the user's option/subscription
      globally.  Site admin can change these only if
      mm_cfg.ALLOW_SITE_ADMIN_COOKIES is set to Yes.
