Questions regarding message acceptance
by Pawel Grzywaczewski 19 Sep '24

19 Sep '24

Hello, I have few questions regarding usage of Mailman3: 1) We have list1 and list2 with members. Can we specify that all members of list1 can post messages to list2? We could potentially write a script that would synchronize members of another list to “Accept these non-members” of another list, but with thousands of lists it will be difficult to maintain lists in synchro. So perhaps there is a concept of adding another list to “Accept these non-members” and mailman real-time evaluate membership of another list upon message arrival? 2) In explanation of “Accept these non-members” it’s written: “While non-regexp addresses can be entered here, it is preferred to add the address as a nonmember and set the nonmember's Moderation to Default Processing”. I noticed that if someone posts to a list then he is added automatically to non-members. Which means that next time he will be able to post. My understanding is that it’s better to use the feature “Accept these non-members”. Am I correct? Thank you, Paweł

Disabled by bounce
by Allan Hansen 11 Sep '24

11 Sep '24

Hi all, Apparently Google just started to get very aggressive about DKIM settings. Some hundreds of my subscribers have had their subscriptions disabled because of Google's bounces. I tried to 'Enable' some of them, expecting that their bounce scores would be reset, but when I list the users, the bounce scores are still 5. Please advise. Will enabling them without the bounce score being reset just cause the server to disable them again. Yours, Allan

How to remove Held Unsubscriptions
by Mark 10 Sep '24

10 Sep '24

Hi As a moderator I receive an email each day for "Held Unsubscriptions" for a subscriber that was unsubscribed by the Owner sometime ago (using "Mass operations"). +++++++++++++++++++++++++++++++ The listname(a)domain.com list has 1 moderation requests waiting. Held Unsubscriptions: User: bart(a)example.com Please attend to this at your earliest convenience. +++++++++++++++++++++++++++++++ There is nothing showing under "Subscription requests > Pending approval". Could anyone tell me how I can stop these email notifications? I have access to the mailman shell and the databases. Thanks, Mark

security app causing django Internal Server Error: /archives/search emails
by sun zi 05 Sep '24

05 Sep '24

Greetings, I have set up a few lists and all seems to be working as expected, however I get a large number of emails due to internal server errors received when my security application is testing exploits to list URLs such as the following: https://<mylistdomain>/archives/search?sort=177120&cauft=&page=1&q=../../../../../../../../../../tmb/wditeteet424465304.txt. Is there any django logging filter changes that can be made to avoid receiving these emails? Any assistance would be greatly appreciated. Thank you!

Display the last post time for a list or all lists.

Does Mailman 3 have something similar to https://www.msapiro.net/scripts/last_post.py displaying the last post time for a list or all lists?

MM3 generates long lines?
by peter＠chubb.wattle.id.au 28 Jul '24

28 Jul '24

I'm seeing emails being dropped when mm3 talks to the local smtp server, with log errors like: 2021-06-23 15:42:24 1lvvea-007r8u-VN H=localhost (<FQDN>) [::1] F=<announce-bounces@<FQDN>> rejected after DATA: maximum allowed line length is 998 octets, got 1036 The email itself did not have such long lines AFAICT. I can disable line length checking on the mailserver, but that sounds like a recipe for the next one along to drop the email. Peter C

Issues with a DMARC record leading to message being shunted

Hi! Recently a mail was not being distributed via our MM3 instance; I searched the logs and found: Dec 22 04:54:27 2023 (24) ACCEPT: <1d431542-b386-467b-8bf2-305f19ee7eb4(a)somenet.org> Dec 22 04:54:28 2023 (28) Uncaught runner exception: list index out of range Dec 22 04:54:28 2023 (28) Traceback (most recent call last): File "/usr/lib/python3.10/site-packages/mailman/core/runner.py", line 179, in _one_iteration self._process_one_file(msg, msgdata) File "/usr/lib/python3.10/site-packages/mailman/core/runner.py", line 272, in _process_one_file keepqueued = self._dispose(mlist, msg, msgdata) File "/usr/lib/python3.10/site-packages/mailman/runners/pipeline.py", line 37, in _dispose process(mlist, msg, msgdata, pipeline) File "/usr/lib/python3.10/site-packages/mailman/core/pipelines.py", line 53, in process handler.process(mlist, msg, msgdata) File "/usr/lib/python3.10/site-packages/mailman/handlers/validate_authenticity.py", line 125, in process authenticate(msg, msgdata) File "/usr/lib/python3.10/site-packages/mailman/utilities/retry.py", line 44, in f_retry return f(*args, **kwargs) File "/usr/lib/python3.10/site-packages/mailman/handlers/validate_authenticity.py", line 93, in authenticate auth_result = authenticate_message( File "/usr/lib/python3.10/site-packages/authheaders/__init__.py", line 395, in authenticate_message dmarc_result = check_dmarc(msg, spf_result, dkim_result, dnsfunc=dnsfunc, psddmarc=psddmarc) File "/usr/lib/python3.10/site-packages/authheaders/__init__.py", line 343, in check_dmarc result, result_comment, from_domain, policy = dmarc_per_from(from_domain, spf_result, dkim_result, dnsfunc, psddmarc) File "/usr/lib/python3.10/site-packages/authheaders/__init__.py", line 90, in dmarc_per_from record, orgdomain = receiver_record(from_domain) File "/usr/lib/python3.10/site-packages/authheaders/dmarc_lookup.py", line 117, in receiver_record retval = lookup_receiver_record(hostSansDmarc, dnsfunc) File "/usr/lib/python3.10/site-packages/authheaders/dmarc_lookup.py", line 92, in lookup_receiver_record tags = answer_to_dict(str(result)) File "/usr/lib/python3.10/site-packages/authheaders/dmarc_lookup.py", line 42, in answer_to_dict retval = {t[0].strip().lower(): t[1].strip().lower() for t in rawTags} File "/usr/lib/python3.10/site-packages/authheaders/dmarc_lookup.py", line 42, in <dictcomp> retval = {t[0].strip().lower(): t[1].strip().lower() for t in rawTags} IndexError: list index out of range Dec 22 04:54:28 2023 (28) SHUNTING: 1703220868.1418982+b27f5db154375fcd2c418d467172e4aad0d3d57a So the message has been shunted, due to this error. Something with DMARC and tags. So I checked the DMARC record for the sending domain somenet.org. It is "v=DMARC1;p=none;pct=100;rua=mailto:postmaster@somenet.org;mailto:postmaster@somenet.org;ri=3600;fo=1;" which is syntactically incorrect. The extra ";mailto:postmaster@somenet.org" is wrong, I guess the tag "ruf=" is missing here! It should probably read "v=DMARC1;p=none;pct=100;rua=mailto:postmaster@somenet.org;ruf=mailto:postmaster@somenet.org;ri=3600;fo=1;" So, should mm3 somehow "catch" this error somehow? According to the DMARC specs, an syntactically incorrect DMARC record should be ignored / handled as if none were present. -- Ralf Hildebrandt Charité - Universitätsmedizin Berlin Geschäftsbereich IT | Abteilung Netz | Netzwerk-Administration Invalidenstraße 120/121 | D-10115 Berlin Tel. +49 30 450 570 155 ralf.hildebrandt(a)charite.de https://www.charite.de

Held messages showing a reason not in English on the Postorious

27 Jun '24

We just notice a held message from a user's list showing the held reason in Ukrainian, but the interface is in US English and the list's preferred language is English (USA). We could not repeat the issue. What can be the reason behind?

A poll: "Delete this thread"
by Sam Darwin 26 Jun '24

26 Jun '24

Hi, If you have a locally installed mailman3 instance, could you try (as an administrator) to visit a thread in Hyperkitty and click "Delete this thread"? Does the thread get deleted, and you return to "Recently active discussions" and everything is fine? Even just a few replies would indicate a pattern. That it's usually ok, for example. I get a spinning wheel, and "Thread matching query does not exist." HyperKitty==1.3.9, PostgreSQL, Ubuntu 22.04, memcached, gunicorn.

Hi, I have a problem with digests not being sent daily (periodically). Mailman 3.3.9 installed in virtualenv Enable Digests = YES Send Digest Periodically = YES Digest size threshold = 0 Cron is set and is running. An error report (below) is generated and emailed.

unique key violation because of case sensitivity of email address
by Jörg Schulz 16 Jun '24

16 Jun '24

After updating to the most recent version of mailman-web, the migrations script issued an error: Apply all migrations: account, admin, auth, contenttypes, django_mailman3, django_q, hyperkitty, postorius, sessions, sites, socialaccount mailman-web | Running migrations: mailman-web | Traceback (most recent call last): mailman-web | File "/usr/lib/python3.12/site-packages/django/db/backends/utils.py", line 89, in _execute mailman-web | return self.cursor.execute(sql, params) mailman-web | ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ mailman-web | psycopg2.errors.UniqueViolation: duplicate key value violates unique constraint "account_emailaddress_user_id_email_987c8728_uniq" mailman-web | DETAIL: Key (user_id, email)=(27, John.Doe(a)mynicedomain.de) already exists. mailman-web |(...) Digging into the db, I found the duplicate to result from a duplicate entry using john.doe(a)mynicedomain.de Obviously, the process that originally created the entry, took case sensitivity literally which doesn't seem to be the case any longer for the migration script. I fixed this by removing one of the duplicates hoping no further errors will come up.... What would have been the better approach?

running a script for the mailman-shell (to discard held messages) gives errors about a package argument for relative import
by stephan.edel＠gmx.net 16 Jun '24

16 Jun '24

Our organization has been been communicating through about a dozen mailing lists, running on mailman, with ~200 subscribers, for 15-odd years. After Debian 10 LTS ran out, I had to upgrade our organisations Debian server, forcing me into mailman3. I haven't managed, yet, to get the web interface running, so I need to do the most urgent tasks in the shell for now. I have found out that, for example, to discard all held messages from the list "motor", I need to > sudo -u list mailman shell -l motor.our-server.de and in the shell, >>> from mailman.app.moderator import handle_message >>> rdb = IListRequest(m) >>> for req in rdb.held_requests: ... if req.request_type == RequestType.held_message: ... handle_message(m, req.id, Action.discard) > commit() Now, obviously, I put these exact lines in a script, so I don't have to type it out every single time, and try to run it using > sudo -u list mailman shell -l testlist.our-server.de -r ./mm_discard_held.py but that invariably gives me ------------------------ Traceback (most recent call last): File "/usr/bin/mailman", line 33, in <module> sys.exit(load_entry_point('mailman==3.3.8', 'console_scripts', 'mailman')()) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/usr/lib/python3/dist-packages/click/core.py", line 1130, in __call__ return self.main(*args, **kwargs) ^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/usr/lib/python3/dist-packages/click/core.py", line 1055, in main rv = self.invoke(ctx) ^^^^^^^^^^^^^^^^ File "/usr/lib/python3/dist-packages/mailman/bin/mailman.py", line 69, in invoke return super().invoke(ctx) ^^^^^^^^^^^^^^^^^^^ File "/usr/lib/python3/dist-packages/click/core.py", line 1657, in invoke return _process_result(sub_ctx.command.invoke(sub_ctx)) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/usr/lib/python3/dist-packages/click/core.py", line 1404, in invoke return ctx.invoke(self.callback, **ctx.params) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/usr/lib/python3/dist-packages/click/core.py", line 760, in invoke return __callback(*args, **kwargs) ^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/usr/lib/python3/dist-packages/click/decorators.py", line 26, in new_func return f(get_current_context(), *args, **kwargs) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/usr/lib/python3/dist-packages/mailman/commands/cli_withlist.py", line 294, in shell r = call_name(dotted_name, m, *run_args) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/usr/lib/python3/dist-packages/mailman/utilities/modules.py", line 69, in call_name named_callable = find_name(dotted_name) ^^^^^^^^^^^^^^^^^^^^^^ File "/usr/lib/python3/dist-packages/mailman/utilities/modules.py", line 52, in find_name module = import_module(module_path) ^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/usr/lib/python3.11/importlib/__init__.py", line 121, in import_module raise TypeError(msg.format(name)) TypeError: the 'package' argument is required to perform a relative import for './mm_discard_held' ------------- I've tried a PYTHONPATH=/root/bin , where mm_discard_held.py lives, as suggested.

To have mailman3 start at boot, trying to configure the systemd mailman3.service unit, but having issues
by Keith Christian 10 Jun '24

Hello, mailman list: Trying to add the mailman3.service unit so that mailman3 will start on system boots/reboots. Seeing different behavior with the mailman3.service unit commands vs. with the "/opt/mailman3/venv/bin/mailman" command line. Everyone on this list is more experienced than I with reading systemd error messages and Python code, so your ideas are appreciated. I am using letters and numbers to navigate the six screenshots in this email, I hope this is helpful, without being too much info. Running the following OS and Python versions.

Email to list owner on list creation only sent when using mailman create --notify command
by Perry Kollmorgen 10 Jun '24

10 Jun '24

Hi, This is only a minor issue, however as a nicety for new list owners I am hoping there is work around or something I have missed. I have the following file: templates/domains/<fqdn_listname/en/domain:admin:notice:new-list.txt When I use the mailman create command with the --notify option the new owners receives an email with the correct template info from the above file. However when I use mailmanclient python bindings or Postorius to create an list, there is no email sent. Is there an option to include a notify option when using mailmanclient or the API direct perhaps ? Or even maybe a way to trigger a notification manually at some point once the list is completely setup including both short and long descriptions ? Thank you. Regards, Perry

Digests not working correctly
by Joel Lord 08 Jun '24

08 Jun '24

So I seem to have problems with both periodic AND size-triggered digests. Size first, this is simpler. Just got one sent out, clearly triggered by a new email getting added to the queued up messages, but the setting for the list is the default 30KB and the digest came out at 23.2 KB. Is it measuring the accumulated queue as size on disk including metadata and filesystem block sizes or something, rather than the size of what the emailed digest will be? Periodic is much more complicated, even to explain. I have the cron job running nightly at 11:00 PM and it certainly seems to be working, except for one really odd thing. The list also definitely has periodic digests enabled in the web UI. This is a very bursty list, so it will go mad with traffic for a few weeks and then will go mostly idle for a month or so. The first digest of a burst is definitely size-triggered, but pretty reliably it has the last few messages from the previous burst in there. So the one I got today had three messages from today and one message from May 4th. But that May 4th message should have gone out at 11:00 PM on May 4th with the daily digest and then gotten flushed from the pending digest queue, right? -- Joel Lord

Using the API to create nonmembers with a different moderation action than the list default
by Perry Kollmorgen 08 Jun '24

08 Jun '24

Hi, My next challenge is to script the setup of a bunch of nonmembers who have a moderation action of accept (or maybe defer) whilst the list itself has a nonmember action of hold. This is due to a relatively heavy use of nested lists, and have a fair number of people who might possibly send to all lists, and are important enough they wouldn't want to be manually allowed each time even if it only once. When using the mailmanclient python bindings I have worked out I can add nonmembers with something like: mailing_list.add_role('nonmember', 'nonmember(a)yourdomain.com', display_name='Non Member') However I can't see anything in the mailmanclient docs which suggest it is possible to configure a member_moderation_action or moderation_action field for that member. I assume I'll need to fall back to using the REST API directly, and most likely something along these lines: 1/ Obtain the member ID for an email address of someone who already been added as a nonmember. 2/ Patch an endpoint which looks something like: /members/{member_id} I'm not able to use the mailman binary (e.g mailman shell) on the mailman-core host itself as I would like to query an existing database of people and reach out to a mailman endpoint from the database host rather than opening that host up to further network access. I figured it might be a good stage in which to ask for a little help and pointers before I continue, perhaps there is something I have missed for a better way to approach this. Thanks.

Trying to save a new style
by Perry Kollmorgen 07 Jun '24

07 Jun '24

Dear Mailman-users list, I have embarked on project to stand up a Mailman3 instance for general staff email announcements and a small number of adhoc lists. I have a fair amount up and working using Docker and Postfix, with generally emails to/from lists working well, as well as the web interface. One of the reasons I've used Mailman3 is the API and mailman shell options which I'm slowly trying to wrap my head around, but having some progress. I have a question for the moment on something which has stumped me, and whilst I may have more questions as I continue on this implementation, I am hopeful someone can point out where I am going wrong on this. Welcome to the GNU Mailman shell Use commit() to commit changes. Use abort() to discard changes since the last commit. Exit with ctrl+D does an implicit commit() but exit() does not. >>> from zope.component import getUtility >>> from mailman.interfaces.styles import IStyleManager >>> manager = getUtility(IStyleManager) >>> >>> for style in manager.styles: ... print(style.name) ... legacy-announce legacy-default private-default >>> >>> >>> from zope.interface import implementer >>> from mailman.interfaces.styles import IStyle >>> @implementer(IStyle) ... class TestStyle: ... name = 'AB-Announce-Style' ... description = 'AB Announce mailing list style.' ... def apply(self, mailing_list): ... mailing_list.admin_immed_notify = true ... mailing_list.admin_notify_mchanges = true ... mailing_list.advertised = false ... mailing_list.allow_list_posts = false ... mailing_list.anonymous_list = false ... mailing_list.archive_policy = "private" ... mailing_list.archive_rendering_mode = "markdown" ... mailing_list.collapse_alternatives = false ... mailing_list.convert_html_to_plaintext = false ... mailing_list.default_member_action = "defer" ... mailing_list.default_nonmember_action = "hold" ... mailing_list.digest_send_periodic = false ... mailing_list.digests_enabled = false ... mailing_list.emergency = false ... mailing_list.include_rfc2369_headers = true ... mailing_list.max_message_size = 40000 ... mailing_list.max_num_recipients = 30 ... mailing_list.member_roster_visibility = "moderators" ... mailing_list.send_goodbye_message = true ... mailing_list.send_welcome_message = true ... mailing_list.subscription_policy = "moderate" ... mailing_list.unsubscription_policy = "moderate" ... >>> manager.register(TestStyle()) >>> >>> commit() >>> >>> for style in manager.styles: ... print(style.name) ... AB-Announce-Style legacy-announce legacy-default private-default So at this point the style has been registered, however it doesn't look to save this permanently. When I quit the shell and log back in, it only shows the original 3 styles. Nor can I see the style from the web interface. Welcome to the GNU Mailman shell Use commit() to commit changes. Use abort() to discard changes since the last commit. Exit with ctrl+D does an implicit commit() but exit() does not. >>> from zope.component import getUtility >>> from mailman.interfaces.styles import IStyleManager >>> manager = getUtility(IStyleManager) >>> >>> for style in manager.styles: ... print(style.name) ... legacy-announce legacy-default private-default >>> Is there a way to save this style permanently ? Thank you for any assistance you can provide. Regards, PerryK

Mailman3 memory footprint
by Marc SCHAEFER 06 Jun '24

06 Jun '24

Hello, It seems the mailman & mailman-web memory footprint are somewhat big. It looks a lot of instances are started. I have seen this: https://gitlab.com/mailman/mailman/-/issues/1050 and added this to the end of /etc/mailman3/mailman-web.py: Q_CLUSTER = { 'workers': 2, 'timeout': 300, 'save_limit': 100, 'orm': 'default', 'poll': 5, } However, it does not seem to really reduce the memory footprint. Any other suggestions? Thank you.

Hello, i already send this question to the plesk-forum but it seems that nobody there can help me :-( After updating from Debian 10 to 11 to 12, I now have mailman3 running on my server I then converted all lists from Mailman2 to Mailman3 following the instructions from mailman. I can access it via the web interface, manage everything etc. When I register on the web interface, I also receive the corresponding mails from Mailman (forgotten password...) Mails are also arriving, at least mails that are not allowed go into the mails to be approved. The problem, however, is that it does not send out any mails, nor do they appear in the archive. When I look in the Mailman-Log I find: May 16 01:44:55 2024 (6833) Cannot connect to SMTP server localhost on port 25 May 16 01:48:15 2024 (61252) error opening connection to nntp_host: localhost [Errno 111] Connection refused May 16 01:48:15 2024 (61252) NNTP error for list vereinsmitglieder(a)ludothek.de: [Errno 111] Connection refused The configuration of Mailman.cfg looks like this: incoming: mailman.mta.postfix.LMTP outgoing: mailman.mta.deliver.deliver smtp_host: localhost smtp_port: 25 smtp_user: smtp_pass: lmtp_host: 127.0.0.1 lmtp_port: 8024 In Mailman manuals I find hints that the transport routes have to be added to the Postfix-config. Doesn't Debian/Plesk do this automatically? Does anyone else have an idea what I need to change to get my mails out? I did the conversion from mailman2 to mailman3 with root because it didn't work with "sudo -u list "m, but the files stored in the file system all belong to list, so that shouldn't be the problem.

Sending to mangled 'From' addresses.
by hansen 05 Jun '24

All, Due to the DMARC mitigation action ‘Replace From: with list address’, it happens often on my lists that someone sends a message to a mangled address, hoping that the message goes to the person listed as the sender. This happens mostly because the mail clients collect previous addresses and use them when as type-ahead candidates for new messages, which may be unrelated to the lists. For example, say the mail client captures my address as “Allan Hansen via <listname>” <listaddress> then later, when the person wants to send a message to me, the type-ahead puts this string in the ’To:’ field: “Allan Hansen via <listname>” and, to make it worse, the actual email address, <listaddress>, is often hidden. The result is that the email gets sent to the list instead of to me, together with (often) personal and (sometimes) embarrassing information. Is there a way to reject messages sent to recipients where the name part of the recipient is of the above format, i.e., "Allan Hansen via <listname>" In other words, filtering is done on the name part of the recipient, not the address part. Should I get onto the other list to request this as an enhancement? Yours, Allan

Recently active discussions - Hyperkitty
by Sam Darwin 04 Jun '24

04 Jun '24

Hi, Sometimes not sure if it's preferable to open a gitlab issue, or chat on the mailing list. I have run a large archive import into mailman3/hyperkitty. After that's done, waited a day, for scheduled cron jobs to complete. In "All Threads", all the email archives are present. The import worked. In "RECENTLY ACTIVE DISCUSSIONS" on the main page, it says: RECENTLY ACTIVE DISCUSSIONS No discussions this month (yet). Nothing there. That means if I direct users to visit the site, the page, it appears empty. That's too bad. :-) It should display recent emails. What would affect this feature during an archive import? Is it a problem with the import script itself, or with a scheduled cron job, or something else? Would you expect "Recently active discussions" be empty when very recent archives do exist? Thanks, Sam

import21 detailed usage instructions in 2024
by Keith Christian 03 Jun '24

1 Soon, I will be executing the first test imports from Mailman2.1 to Mailman3.9. 2 Planning to copy over the entire production Mailman2.1 to a new directory structure on the Mailman 3.9 machine. 3 Expecting that all .mbox and .pkl files will be present and no special work has to be done to bring them over will a "full" mailman2.1 copy. 4 Can the import21 program find the mailman2.1 .mbox and .pkl files on its own and process them? 5 Other than the mailman2.1 instance being shut down, any other prep that needs to be done? 6 Any special command line parameters to be aware of for import21? 7 Is there a list of troubleshooting steps for commonly encountered migration issues? Thanks. ------------------ Keith
