[Bug 1462755] [NEW] qrunner crashes on invalid unicode sequence
by Thijs Kinkhorst 28 Feb '22

28 Feb '22

Public bug reported: When a message contains an invalud unicode sequence in its header, qrunner flat out crashes on that: May 17 15:32:20 2015 (981) Uncaught runner exception: 'utf8' codec can't decode byte 0xe9 in position 18: invalid continuation byte May 17 15:32:20 2015 (981) Traceback (most recent call last): File "/var/lib/mailman/Mailman/Queue/Runner.py", line 119, in _oneloop self._onefile(msg, msgdata) File "/var/lib/mailman/Mailman/Queue/Runner.py", line 190, in _onefile keepqueued = self._dispose(mlist, msg, msgdata) File "/var/lib/mailman/Mailman/Queue/IncomingRunner.py", line 130, in _dispose more = self._dopipeline(mlist, msg, msgdata, pipeline) File "/var/lib/mailman/Mailman/Queue/IncomingRunner.py", line 153, in _dopipeline sys.modules[modname].process(mlist, msg, msgdata) File "/var/lib/mailman/Mailman/Handlers/CookHeaders.py", line 239, in process i18ndesc = uheader(mlist, mlist.description, 'List-Id', maxlinelen=998) File "/var/lib/mailman/Mailman/Handlers/CookHeaders.py", line 65, in uheader return Header(s, charset, maxlinelen, header_name, continuation_ws) File "/usr/lib/python2.7/email/header.py", line 183, in __init__ self.append(s, charset, errors) File "/usr/lib/python2.7/email/header.py", line 267, in append ustr = unicode(s, incodec, errors) UnicodeDecodeError: 'utf8' codec can't decode byte 0xe9 in position 18: invalid continuation byte May 17 15:32:20 2015 (981) SHUNTING: 1431869540.389822+156779307d54473d0eb732994bb67eee95733285 A solution for this specific case is to have Mailman/Handlers/CookHeaders.py pass the erorrs='replace' parameter. I would say that this is actually a bug in python-email, since I think it doesn't make sense to set errors to "strict" rather than something like "replace" when the intention is to parse stuff so free-formed, under-specd and user-controlled as email. Nonetheless, Mailman already sets errors='replace' in some places so it might aswell add it here. ** Affects: mailman Importance: Undecided Status: New -- You received this bug notification because you are a member of Mailman Coders, which is subscribed to GNU Mailman. https://bugs.launchpad.net/bugs/1462755 Title: qrunner crashes on invalid unicode sequence To manage notifications about this bug go to: https://bugs.launchpad.net/mailman/+bug/1462755/+subscriptions

[Bug 544477] [NEW] setting localhost in postfix_lmtp breaks delivery
by Patrick Ben Koetter 27 Sep '20

27 Sep '20

Public bug reported: Setting localhost in postfix_lmtp works against Postfix defaults and breaks delivery. Reason: The Postfix lmtp client only uses dns queries by default to search for hostnames. If the DNS server does not provide an answer for "localhost" delivery from the lmtp client to mailman fails. Solution: Provide "127.0.0.1" instead of "localhost". This does not require DNS and is even faster because it saves DNS lookups. Example: hey2(a)mailman.state-of-mind.de lmtp:[localhost.localdomain]:8024 ** Affects: mailman Importance: Undecided Status: New ** Tags: 3.0 mailman -- setting localhost in postfix_lmtp breaks delivery https://bugs.launchpad.net/bugs/544477 You received this bug notification because you are a member of Mailman Coders, which is subscribed to GNU Mailman.

[Bug 1731604] [NEW] VERP fails if the recipient address local part is quoted.
by Mark Sapiro 13 Apr '20

13 Apr '20

Public bug reported: We have seen (very rarely) cases where a recipient address has a quoted local part such as "jr."@example.org. This results in a VERPed sender address like list-bounces+"jr."=example.org(a)example.com which is syntactically invalid. The VERPed sender should be "list- bounces+jr.=example.org"@example.com in this case. I.e., the entire VERPed sender local part should be quoted, not just the recipient local part. This also requires BounceRunner to recognize this and restore the original local part. ** Affects: mailman Importance: Medium Assignee: Mark Sapiro (msapiro) Status: In Progress -- You received this bug notification because you are a member of Mailman Coders, which is subscribed to GNU Mailman. https://bugs.launchpad.net/bugs/1731604 Title: VERP fails if the recipient address local part is quoted.

[Bug 883193] [NEW] Remove the X- prefix from some headers
by Barry Warsaw 15 Jan '19

15 Jan '19

Public bug reported: MM3 still uses a lot of X- headers, but some of the X- prefixes can be removed. In general, we can just claim the Mailman- prefix for Mailman specific headers. Candidates include: Mailman-Rule-Hits Mailman-Rule-Misses Mailman-Version Mailman-Approved-At Mailman-LMTP-MailFrom (i.e. X-MailFrom) Mailman-Copy (or remove this header) Mailman-Content-Filter (from X-Content-Filtered-By) Also, fix the outdated comments about add-dup-header in avoid_duplicates.py and verp.py. Probably also get rid of X-List-Administrivia (and possibly reduced_list_headers). These seem unnecessary now. ** Affects: mailman Importance: Undecided Status: New ** Tags: mailman3 -- You received this bug notification because you are a member of Mailman Coders, which is subscribed to GNU Mailman. https://bugs.launchpad.net/bugs/883193 Title: Remove the X- prefix from some headers To manage notifications about this bug go to: https://bugs.launchpad.net/mailman/+bug/883193/+subscriptions

[Bug 1094696] [NEW] Event notifications on postings
by George Chatzisofroniou 23 Dec '18

23 Dec '18

Public bug reported: It looks like there is no way for a MM3 plugin to be signaled for a new posting. It would be great if core could provide a notification to the plugins that have subscribed to this event when a new post occurs. This notification should carry some interesting information, like the number of recipients and the message size. This request is also essential for the MM3-Metrics module (https://launchpad.net/mm3-metrics). ** Affects: mailman Importance: Undecided Status: New ** Tags: events mailman3 metrics modules notification plugins post -- You received this bug notification because you are a member of Mailman Coders, which is subscribed to GNU Mailman. https://bugs.launchpad.net/bugs/1094696 Title: Event notifications on postings To manage notifications about this bug go to: https://bugs.launchpad.net/mailman/+bug/1094696/+subscriptions

[Bug 1414352] [NEW] Improve code coverage by adding tests
by Terri 23 Dec '18

23 Dec '18

Public bug reported: Mailman Core and Postorius have sets of tests, but could use more extensive test coverage. This bug is meant to be a repeatable bug suitable for new contributors (e.g. prospective Google Summer of Code Students). In short: find a piece of Postorius or Mailman Core that isn't yet tested and write a test (or set of tests) for it. Contributors wishing to work on Mailman Core should look at START.rst and DATABASE.rst for more information about setting up tests. For Postorius, Florian is working on vcrpy test integration, so new tests can use that format.

[Bug 1696066] [NEW] Postfix module - Mailman wrapper - Couldn't write data/aliases.db and data/virtual-mailman.db files
by Laurent Declercq 15 Jun '18

15 Jun '18

Public bug reported: Dear project leader At least in version 2.1.23, there is a bug regarding permissions set for Mailman data/aliases table and Mailman data/virtual-mailman map when these files are created from scratch. Here I describe the current behavior for the Mailman data/aliases table only but the problem is identical for the Mailman data/virtual-mailman map. In order, the following conditions have to be met: - Postfix need read access to the aliases.db file - Mailman like to be owner of those files and the Mailman group needs write access to them I. Postfix needs a read access to the aliases.db file We can either set permissions as 0660 and add postfix user to mailman group (what I've done), or set the permissions as 0664 II. Mailman group needs a write access to those files at any time The following behavior has been observed: When creating a new list on command line, using bin/newlist script as follow: # newlist -u virtualhost foobar the files will be created as follow: -rw-rw---- 1 root list aliases -rw-r----- 1 root list aliases.db The same thing has been observed when recreating the file from scratch using bin/genaliases: -rw-rw---- 1 root list aliases -rw-r----- 1 root list aliases.db Note that in both cases, files were not present. Thus, they were created from scratch. As you can see here, the Mailman data/aliases table is created with the expected group and permissions but the data/aliases.db file is only writable by owner. From the POSTALIAS(1) command point of view, that is the expected behavior: The file is created with the same group and other read permissions as their source file. The problem here is that with those permissions, creating a list through Mailman interface later on will result in a permissions denied error because the Mailman group, through the wrapper, cannot write (update) the aliases.db file (no write permissions). That is really a problem. Of course, one can just pre-create the files as follow: # cd /var/lib/mailman # sg list -c "touch data/aliases && postalias data/aliases" # chmod 0660 data/aliases* but that seem tedious. What if at some point (for any reason), the files get recreated from scratch? So, from my point of view, the MTA/Postfix.py module should always set correct permissions on resulting *.db file, after running POSTALIAS(1) command to be sure that Mailman group has write permissions, at least when the files are created from scratch.

Thank you. ** Also affects: mailman (Ubuntu) Importance: Undecided Status: New ** Also affects: mailman (Debian) Importance: Undecided Status: New ** Description changed: Dear project leader At least in version 2.1.23, there is a bug regarding permissions set for Mailman data/aliases table and Mailman data/virtual-mailman map when these files are created from scratch. Here I describe the current behavior for the Mailman data/aliases table only but the problem is identical for the Mailman data/virtual-mailman map. In order, the following conditions have to be met: - Postfix need read access to the aliases.db file - Mailman like to be owner of those files and the Mailman group needs write access to them I.

Thus, they were created from scratch. As you can see here, the Mailman data/aliases table is created with the expected group and permissions but the data/aliases.db file is only writable by owner. From the POSTALIAS(1) command point of view, that is the expected behavior: The file is created with the same group and other read permissions as their source file. The problem here is that with those permissions, creating a list through Mailman interface later on will result in a permissions denied error because the Mailman group, through the wrapper, cannot write (update) the aliases.db file (no write permissions). That is really a problem. Of course, one can just pre-create the files as follow: # cd /var/lib/mailman # sg list -c "touch data/aliases && postalias data/aliases" # chmod 0660 data/aliases but that seem tedious.

[Merge] lp:~futatuki/mailman/2.1-add-smtp-timeout into lp:mailman/2.1
by Yasuhito FUTATSUKI＠POEM 09 Feb '18

09 Feb '18

Yasuhito FUTATSUKI at POEM has proposed merging lp:~futatuki/mailman/2.1-add-smtp-timeout into lp:mailman/2.1. Requested reviews: Mailman Coders (mailman-coders) For more details, see: https://code.launchpad.net/~futatuki/mailman/2.1-add-smtp-timeout/+merge/33… This add a feature to specify timeout for SMTP response to avoid waiting response forever, to SMTPDirect Handler. To specify timeout, set SMTP_TIMEOUT in mm_cfg.py. By default, this is disabled(waiting response until respond the MTA). To test this feature, set mm_cfg.SMTP_TIMEOUT to small value and setup MTA to wait responding (by using greet pause feature, etc) and run smtp test or post message to mailing list to deliver it. -- Your team Mailman Coders is requested to review the proposed merge of lp:~futatuki/mailman/2.1-add-smtp-timeout into lp:mailman/2.1.
