disable body transcoding
by Markus Schaaf 23 Sep '21

23 Sep '21

Hi, I have disabled all message modifications and filtering from within the webUI, and created empty header and footer template files. Still, some list messages get their body encoding changed to base64, breaking DKIM. What can I do to prevent this? (I'm a newbie to mailman3, so please give somewhat complete commands. I have read other threads with similar questions, but did not understand some shortened configuration commands.) BR

Username being set to givenname for socialaccount login
by cfarley＠iastate.edu 22 Sep '21

22 Sep '21

I have a new mailman3 install setup with Okta as a social application. This is working well for logins and data comes through as expected, but for some reason the username is being set at to a lowercase version of the given_name. The Extra data on the social users in the admin interface looks good, so I don’t think it’s a problem with the attributes coming from Okta. We have tried a number of variations on the below setting, but that all of them other than the default of “username” end up with the username being empty. ACCOUNT_USER_MODEL_USERNAME_FIELD = “email” Any direction would be welcome. Thank you!

Django primer for Mailman admins
by Abhilash Raj 20 Sep '21

20 Sep '21

Hey Everyone, This weekend I wrote some documentation[1] that I thought would be useful for Mailman admins when dealing with Django, since it is a frequent topic on -users list. The intent was to add only required information for admins to work with Mailman installs and provide enough pointers to right places, wherein more information can be found instead of duplicating them in Mailman's docs since it it often goes stale. Since the most common theme of questions are configuration (settings), management commands and deployment (running), I distributed the whole page in those three sections. If you as a system admin had to spend some time figuring out certain things about Django, it would be good to respond on this thread or just open a MR with additions to the page[1]. [1]: https://docs.mailman3.org/en/latest/django-primer.html I also made a small architecture diagram of the various components in a typical Mailman 3 install[2] since we didn't had any such existing diagram. Suggestions to this are also welcome. [2]: https://docs.mailman3.org/en/latest/architecture.html -- thanks, Abhilash Raj (maxking)

Mailman3 subscribe over command line
by tibor.molnar＠waltoninstitute.ie 20 Sep '21

20 Sep '21

I would be looking to be able to subscribe people to multiple lists through command line. Mailman 2.1 did have an add_members script we used but I'm not able to use this module in mailman3. Can anyone suggest a script or approach to this issue? Thank you, Tibor

very few moderation capabilities for moderators
by Guillermo Hernandez (Oldno7) 19 Sep '21

19 Sep '21

Hi all: I need to provide the list moderators a way to change the moderation flag for users from whichever it is (normally "list default processing") to "hold for moderation" and viceversa (to "list default" or to "accept") I understand that it could be done via console script (That's the way I did on mailman2: I made two commands using "withlist", one to hold, moderar.py, and other one to accept, desmoderar.py. I show you below) But I think I'm not the only one that could use as an improvement a way to do this on postorius/web. Before to trying implementing them on mailman3, I beg you to tell me if they could do that on mailman3. Thanks in advance. ****************** (moderar.py) #! /usr/local/bin/python # # script via withlist para moderar a pelo # """moderar un miembro. Save as bin/moderar.py Run via bin/withlist -r moderar <listname> <member> """ from Mailman import mm_cfg def moderar(mlist, member): if not mlist.Locked(): mlist.Lock() mlist.setMemberOption(member, mm_cfg.Moderate, True) mlist.Save() mlist.Unlock() ****************** (desmoderar.py) #! /usr/local/bin/python # # script via withlist para desmoderar un miembro # """desmoderar un miembro. Save as bin/desmoderar.py Run via bin/withlist -r desmoderar <listname> <member> """ from Mailman import mm_cfg def desmoderar(mlist, member): if not mlist.Locked(): mlist.Lock() mlist.setMemberOption(member, mm_cfg.Moderate, False) mlist.Save() mlist.Unlock() --

mm3mod: command line moderation tool
by David Bremner 18 Sep '21

18 Sep '21

Because we're not running postorius, and the moderate-by-mail change is not available in the older version of mailman3 we're running, I needed a tool to moderate lists from the command line. I found mailman-tools, but wasn't able to get them working with python3, so I started from scratch. Maybe someone else will find it useful https://git.tethera.net/mm3mod.git/about/ It's a work in progress, but I am running the version from that repo in production. Like any program using the REST interface, in principle this has complete administrator access to your mailman site, so you need to to trust both this code and the users you let run it. I do run it in "kiosk mode" via ssh command="/home/listmod/.local/bin/mm3mod" ssh-rsa blahblah in .ssh/authorized_keys. This is more of a keeping-honest-people-honest kind of thing.

Controlling Mailman3 from the Linux commandline
by Allan Hansen 18 Sep '21

18 Sep '21

All, Not versed in Python, I found using the Python gateway to Mailman3 commands rather cumbersome for the few and very simple interactions I have with the shell. So I implemented a set of .bash scripts that I use instead. They all have this from, where the last part is the Mailman shell command (in this case the command for adding members in file $1 to the list $2). #!/bin/bash exec /opt/mailman/mm/venv/bin/mailman -C "/opt/mailman/mm/mailman.cfg" members --addmembers $1 $2 To invoke it: . addMembers.bash <FILE_OF_EMAIL> <listname> I have other scripts for commands such as: List all lists List all members on all lists (with a sort -u) Send an email with a given list's members to a given address Delete members from a list Delete members from all lists Help Count members on a list Note the one that sends the member list to a given email address. It does this: #!/bin/bash exec /opt/mailman/mm/venv/bin/mailman -C "/opt/mailman/mm/mailman.cfg" members $2 |grep -v -e "has no members"|sed -e 's/.*/\L&/'|mailx --subject=$2 $1 This one I use a lot because the system has a bug that does not allow moderators to see the list of members on the list they are supposed to moderate. My lists are set up to allow this, but it does not work. The moderators send me an email with the request, I log on and run this script. I hope this is helpful. Yours, Allan

Docker mailman3 delete social logins, did something change?

Running mailman shell commands in a script
by Eggert Ehmke 16 Sep '21

16 Sep '21

Hello, I understand that the mailman shell is basically interactive. I need to run some actions as adding and deleting users in a Linux shell script, or even from another python program. How does that work? In fact, I miss the commands that were in the bin directory of the old mailman2 installation. Wouldn't it be nice to add them again to mailman3? Cheers, Eggert

Blocking email addresses

Does anyone have a working DKIM/ARC configuration?
by Philip Colmer 16 Sep '21

16 Sep '21

I've configured a Mailman 3 server with Postfix and added OpenDKIM to the latter to provide the DKIM headers, and configured Mailman to provide the ARC headers. However, in sending test messages to a mailbox hosted by Microsoft, I'm seeing a header like this: ARC-Authentication-Results: i=2; mx.microsoft.com 1; spf=pass (sender ip is 1.2.3.4) smtp.rcpttodomain=destination.org smtp.mailfrom=mmserver.org; dmarc=bestguesspass action=none header.from=mmserver.org; dkim=test (signature was verified) header.d=mmserver.org; dkim=fail (signature did not verify) header.d=sender.org; arc=fail (47) (I've changed the domains and IP address) Manually sending an email from the server to the same external email address does give me an email with a valid DKIM header: Authentication-Results: spf=pass (sender IP is 1.2.3.4) smtp.mailfrom=mmserver.org; destination.org; dkim=test (signature was verified) header.d=mmserver.org;destination.org; dmarc=bestguesspass action=none header.from=mmserver.org;compauth=pass reason=109 So I'm unclear as to where the problem may lie ... Hence the question: does anyone have Mailman 3 + Postfix working successfully with DKIM and ARC? Thanks. Philip

See https://gitlab.com/search?search=mailman&group_id=&project_id=&snippets=fal… I see that core is update frequently but other packages such as Mailman web have not been. mailman-suite is two weeks old. Mailman Web has not been updated for wo weeks. Does that mean I can download that Postorius and it will work with the latest mailman core updated in the past day? I expect that most changes don't break interfaces. Is that correct? Brett

External Mail-Server?
by Florian Schulze 12 Sep '21

12 Sep '21

Hi! Is it possible to use an external Mail-Server? Does mailman3 support that directly, or would I have to setup a local MTA which somehow fetches incoming mails from the external inbox and uses the external Mail-Server for delivery? Does anyone do that and have example configurations? Regards, Florian Schulze

New messages not being archived
by Sarah H 07 Sep '21

07 Sep '21

I have 2 active lists that are properly mailing out and working, plus an admin testing list that is as well. The list info pane correctly shows the mail volume and the imported archives from the previous 2.1 installation are present for both active lists. None of the 3 lists are generating new entries in the archive, all 3 are set up with default settings except 1 active and admin are set to private. I know that hyperkitty is showing some new content as admin was created in postorius and the list is present in hyperkitty and working in mailman. None of the logs show anything of note, mailmanweb.log has no new entries since it caused a serious issue when I changed the domain, uwsgi-error is the same and uwsgi.log has proper access logs. When trying to add a new thread via the hyperkitty interface I can see the email go through the maillog, I get the email with the entered content and everything else works, it just doesn't add a new thread to the archive. The installation is set up with the default settings from the virtualenv installation guide. Any assistance would be appreciated.

Mailman container images 0.3.12 is now out
by Abhilash Raj 05 Sep '21

05 Sep '21

Hey Everyone, I have just tagged release 0.3.12 on Github for container images for Mailman 3[1]. This release includes the fix for CVE-2021-40347 that was announced earlier today. For the folks using 0.3 or 0.3.11 release tags, it is highly recommended that you upgrade to this release. This release also bumps the version of Mailman Core to 3.3.4, Mailmanclient to 3.3.3 and Django-mailman3 to 1.3.7. Note that is since the main and v0.3.12 branches are different in many ways, the default documentation[2] and the docker-compose.yaml files in the main branch aren't accurate if you are using the stable release. Please refer to the README[3] at v0.3.12 tag in the Github repo for more accurate docker-compose.yaml and documentation. The project has grown large enough that we need to start versioning the documentation, if someone has experience with versioning docs using Github pages and mkdocs, then I very much need some help here! For those of you who are using the rolling release, it is recommended that you **don't** upgrade to this stable release. The fixes have been pulled into the rolling tags too, so just make sure that you upgrade to the latest published version of rolling release, which as of this writing should be based off on fda837f8d15540e190992c30f7971f50fca54dac commit[4]. This might not be the latest by the time you upgrade if I add a new commit, so look for versions published after 4:00 PM PST 9/5/2021. I am also working on cutting a new release, 0.4.0, which is backwards incompatible with the setup required to talk to web server and MTA (hence the minor version bump!). That should bring the rolling releases and stable releases closer to each other and add improvements around not needing static IPs in the docker network anymore, plus several bug fixes. If someone wants to test the upgrade to 0.4.0 from 0.3 release and is willing to try out the instructions at [5], it would give me some confidence in cutting out the release sooner. The only thing stopping the release of 0.4.0 images is that I haven't verified if the upgrade from 0.3 is documented enough or not. For all the registries listed in README[6], I am still trying to push to Quay (maybe I need to just skip pushing to Quay :-). So, just use the other two to pull the images, Github (ghcr.io) has more generous pull download policy for un-authenticated users though.

New vulnerability in Hyperkitty master branch
by Abhilash Raj 05 Sep '21

05 Sep '21

Hey Everyone, A new vulnerability was reported against Hyperkitty’s git master branch branch which can expose the archives of a private Mailing List through the new Feeds API that was added to Hyperkitty recently to someone who isn't a member or logged-in. Thanks to Ngo Wei Lin for reporting this vulnerability. This bug does not affect any stable released version of Hyperkitty and only affects installations from source (1.3.5b1 version). To differentiate from the vulnerable version, I have bumped the version in master branch to 1.3.5b2, so if you have 1.3.5b1 installed, you should upgrade! The fix for this bug has been committed to master branch[1][2] less than an hour ago as of this writing. If you are using git branches to install Hyperkitty, you can upgrade using the following command: $ pip install --upgrade git+https://gitlab.com/mailman/hyperkitty@master I have also triggered a build for Mailman container images[3] with this changes, so if you are using the rolling container images (which are the only affected ones), then you should upgrade to the latest one when the build[1] finishes (approximately in next 30mins). Do note that this version of rolling release of mailman-web image also includes the fix for the vulnerability announced against Postoruis earlier today. You can verify that you have the fixed version of Hyperkitty in the image by running: $ docker run -it --entrypoint bash maxking/mailman-web:rolling bash-5.0# pip list | grep HyperKitty HyperKitty 1.3.5b2 Ensure that you get 1.3.5b2 version. [1]: https://gitlab.com/mailman/hyperkitty/-/merge_requests/362 [2]: https://gitlab.com/mailman/hyperkitty/-/commit/ed086015acbf66ba377e2af7f6e7… [3]: https://github.com/maxking/docker-mailman/runs/3519658592 -- thanks, Abhilash Raj (maxking)

CVE-2021-40347: New security release for Postorius
by Abhilash Raj 05 Sep '21

05 Sep '21

Everyone, A security vulnerability was reported against Postorius recently which allows any logged-in user to unsubscribe any other member on any other list on same Mailman installation using a specially crafted POST request due to a missing ownership check. This has been assigned CVE-2021-40347. This affects all past versions of Postorius including 1.0.0. Thanks to Kunal Mehta for the security report and a quick patch to fix the vulnerability. I am also attaching a minimal patch that fixes it along with this email, without tests and NEWS so that it applies to older versions of Postorius easily (I have tested the included patch with 1.3.3, 1.3.2 git tags). Upgrading to 1.3.5 release is highly recommended and it mostly includes the fix for this vulnerability (and a small compatibility fix for django-mailman3 1.3.6) so it shouldn’t introduce any other bugs. You can upgrade to this release by running: $ pip install postorius==1.3.5 A full change log is available here[1] as usual and can be downloaded from PyPI[2]. [1]: https://docs.mailman3.org/projects/postorius/en/latest/news.html#news-1-3-5 [2]: https://pypi.org/project/postorius/1.3.5/ Since there aren't many changes, this release requires 3.5+ like 1.3.4. Although, note that the next release will drop support for 3.5 and will support 3.6 only. For those of you who use container images, I am working on 0.3.12 of container images right now, so look out for that announcement. For those of you using the rolling releases, you can already upgrade to the latest version of the rolling release as it has the fix. -- thanks, Abhilash Raj (maxking)

domain owner role

Dear all, recently, I have added one account to a domain as domain owner. I did expect the new owner to see all lists in that domain in Postorius, but he sees no list at all.

How to increase maximum size of the message in mailman
by Shashikanth Komandoor 31 Aug '21

31 Aug '21

Hi Team, I am currently running Mailman 3 with version 3.3.1 and in-built postfix version 2.10.1-6 on RHEL 7.5 with PostgreSQL 11.7 version with default values. I am almost running 2200 lists with 128 GB RAM and 24 Cores on a single VM and on which all the mailman 3 components are running. I have been running this setup in production for the past 2 years and 6 months. I have recently encountered a scenario where a user sent mail with a PPT attachment to one of the lists on the said mailman server. The mail is received by postfix on the mailman server and is handed over to mailman at *0.0.0.0:8024 <http://0.0.0.0:8024>.* But the /var/log/maillog says the below error during the above hand shake. *status=bounced (host 0.0.0.0[0.0.0.0] said: 552 Error: Too much mail data* I have browsed google for understanding and fixing the issue. During which I encountered the information given by Mr. Mark Sapio at https://lists.mailman3.org/archives/list/mailman-users@mailman3.org/thread/…. But I could not fix the issue as it is mentioned the default size limit is 33554432. I request someone to suggest where I can customize the value 33554432 and put a higher value or can be configured without any limit. I have configured message_size_limit as 100MB at postfix level. I would like to configure, in fact, the same at mailman level too. But I don't understand where to edit. I tried editing the variable DATA_SIZE_DEFAULT value in /var/lib/mailman/mailman/.tox/py36-nocov/lib/python3.6/site-packages/aiosmtpd/smtp.py file but unfortunately no luck. So, could someone please help us in this regard ? Also, please also let me know if there is any limitation specific for the attachments so that I can customize that too respectively. -- Thanks & Regards, Shashi Kanth.K 9052671936

Hi Team, One of my colleagues is trying to become a member of the mailman-users list but she is not able to become so even after sending multiple emails to the list. Could someone suggest this ? -- Thanks & Regards, Shashi Kanth.K 9052671936

Question about message bounce stats
by Ruth Ivimey-Cook 30 Aug '21

30 Aug '21

When I used Mailgun some time back, it had a feature of, for any specific outgoing mailing, being able to show you stats and other details of which mails were received ok, which bounced, and which were undeliverable, which I found helpful to check every so often. Their system also kept track of long-term trends, eg for addresses that frequently failed. Does Mailman3 keep such stats, and if so is there any way to get access to them, even if only API? I would think it useful to do so (and yes, for individual outgoing messages at least for a period). Regards, Ruth -- Tel: 01223 414180 Blog: http://www.ivimey.org/blog LinkedIn: http://uk.linkedin.com/in/ruthivimeycook/

auto-away notices as bounces
by Andreas Barth 30 Aug '21

30 Aug '21

Hi, I had a user complaint that his subscription was disabled. Looking into details, his mail provider sent out lots of auto aways notices marked with Auto-Submitted: auto-replied (vacation) Should we not exclude these as being counted as bounce? (List settings are "Individual" for "Personalize" and yes for both "Include RFC2369 headers" and "Include the list post header". Regards, Andi

(nagios-)Monitoring for mailman3?
by Andreas Barth 29 Aug '21

29 Aug '21

Hi together, does anyone have a sensible nagios monitoring for mailman3? (I had the issue that after a data base restart mailman3 was somehow disturbed but the basic web interface was still available, just the detailed pages like .../lists/$listid/ showed the error) Andi

Logging subscriptions and unsubscriptions
by Christian Schoepplein 28 Aug '21

28 Aug '21

Hi, I am in the process to migrate from mailman 2 to mailman 3 and currently I am setting up the new environment and do some tests and play around with the new system. I'd like to have a seperate log for list subscriptions and unsubscriptions. For that reason I added the following section to the mailman-extra.cfg file: [logging.subscribe] path: subscribe.log That created a file called subscribe.log but not everything regarding subscription / unsubscriptions is added to the file. When subscribing and unsubscribing a user via mail only the following line is shown: Aug 27 10:58:31 2021 (28) tmod(a)mm3.example.com: held subscription request from chris(a)example.com Nothing regarding the finished subscription and absolutely nothing regarding the unsubscription performed later. Also in mailman.log I can find the following lines: Aug 27 10:58:05 2021 (28) deque: do_confirm_verify Traceback (most recent call last): File "/usr/lib/python3.8/site-packages/mailman/app/workflow.py", line 69, in __next__ return step() File "/usr/lib/python3.8/site-packages/mailman/app/subscriptions.py", line 356, in _step_send_confirmation raise StopIteration StopIteration Aug 27 10:58:31 2021 (28) deque: subscribe_from_restored Traceback (most recent call last): File "/usr/lib/python3.8/site-packages/mailman/app/workflow.py", line 69, in __next__ return step() File "/usr/lib/python3.8/site-packages/mailman/app/subscriptions.py", line 326, in _step_get_moderator_approval raise StopIteration StopIteration Aug 27 10:58:33 2021 (29) OWNER: <163005471133.28.13827351997075408419@mailman-core> Is this because a higher logging level or is this an error? I can find nothing really helpfull regarding subscriptions and unsubscriptions in any logfile. Is this wanted or can this changed by any configuration setting or are this information stored in the database? Cheers, Schoepp

Unwanted E-mail to Maillists Submitted via Postorius Interface
by matthew＠alberti.us 28 Aug '21

28 Aug '21

Hi Everyone, I’ve seen a recent uptick in SPAM messages making it into mailing lists. Looking at the raw, it seems that the e-mails are being submitted thru the Postorius/Hyperkitty “Start a New Thread” interface. Is there a way to turn that off? We would want people to only be able to post via e-mail. Part of the problem is that our anti-spam system RSPAMD trusts the mailman-web IP… so it doesn’t scan things originating from there.. ☹ Another uestion: Is there a way to implement captcha, or is there a recommended gate that can be put in the signup process? Apparently bots are finding a way thru the signup process, and then sending messages to the list via the Postorius web interface. There seems to be a Django plugin for it; but it appears the Mailman code would have to be adjusted to implement it. I’m open to any suggestions, including on places to check for misconfiguration. 😊 Thanks. - Matt Alberti

docker mailman-core mailman3 image not responding on port 8024

Error on timeout vs retry values
by Robert Moody 25 Aug '21

25 Aug '21

Hi everyone, I have recently setup a new mailman3 service using the venv method. Everything is functionally working however I keep getting an error sent to the mailman email every min which I can not seem to figure out why. /opt/mailman/venv/lib/python3.7/site-packages/django_q/conf.py:142: UserWarning: Retry and timeout are misconfigured. Set retry larger than timeout, failure to do so will cause the tasks to be retriggered before completion. See https://django-q.readthedocs.io/en/latest/configure.html#retry for details. See https://django-q.readthedocs.io/en/latest/configure.html#retry for details.""" I have edited the timeout and retry values in the /opt/mailman/venv/lib/python3.7/site-packages/django_q/conf.py file and restarted both mailman and mailman-web however this still keeps repeating. Any ideas? Regards, Robert -- This message has been scanned for viruses and dangerous content by MailScanner, and is believed to be clean.

Mailman backend maintenance task
by eugenio.jordan＠esa.int 24 Aug '21

24 Aug '21

Dear all. My apologies if the answer to this question is obvious, but I am pretty newbie for 3 version, and to be very honest I haven't had enough time yet to have a deep look into the documentation. Our customer is currently using PostGRESQL as backend, and we would like to perform some maintenance tasks, namely running vacuum full, or at least trying to rebuild hyperkitty_email primary key related index. We have been asked on the real impact of putting in place such initiative. Though the latter is related to archiving, I haven't found a way to stop just Hyperkitty or Django related processes other than stopping Mailman's core, hence preventing mails addressed to distribution lists from being delivered, could you please confirm if I am correct? Regarding the former, as far as I have read, the "mappings" lists -> addresses are stored just in the database, so if we run some kind of procedure or task like vacuum which will lock exclusively tables, or want anyway to have the database stopped for a cold backup or whatever, Mailman willl not work, that is, again the mails addressed to the distribution lists will not be delivered. Will you please confirm this point, too? Really wish we had a testing environment to have been able to check this ourselves and not bothering others, but unfortunately we lack it, and we need to provide an answer as soon as possible. Thanks a lot for your time. Best regards.

Installing mailman3 from Ubuntu 20.04 repository
by Andy Cravens 24 Aug '21

24 Aug '21

I’m testing Mailman3 on Ubuntu 20.04 and installing the packages from the default Ubuntu repo. I’m not sure I’ll perform the install this way once we move to production. I don’t know what group is responsible for keeping the Mainlam3 package in the Ubuntu repository up to date but I’d like to find out how committed that groups is to keeping the package current. We patch often and it would be convenient if the Mailman3 package is kept updated and current. If there is going to be some significant lag time I may decide to install manually when we go to production. Any thoughts on this? — Andy

Hi everyone, from here: https://hosted.weblate.org/projects/gnu-mailman/hyperkitty/it/ I see that there is a way to change the language of mailman3, postorius and hyperkitty But I don't find how. I read that you can download the .po files for the chosen language, but I didn't understand how to use these files. Could anyone show me how to do it? Thank you in advance. Max

Error when disabling signup
by Rainer Herbst 17 Aug '21

17 Aug '21

Dear all, over the last couple of weeks, I have installed and configured mailman3 using the docker containers. It took me some time, but now it works quite well. At last, I wanted to disable the sign-up because only LDAP users should be able to login. As described in django_mailman3/views/user_adapter.py, I added the following line to my settings_local.py: ACCOUNT_ADAPTER = 'django_mailman3.views.user_adapter.DisableSignupAdapter' After that, an error is thrown: ModuleNotFoundError at /accounts/login/ No module named 'django_mailman3.views.user_adapter' What could be the reason for that and how to solve it?

Mailman3 Issue with Sending Mail to Yahoo/AOL
by chris＠zimmerman.to 11 Aug '21

11 Aug '21

Hi everyone. I have a dedicated Ubuntu box that is running mailman3. I have a single email list on it. The subscriber base is about 350 users. There is a good chunk of these users that are aol.com or yahoo.com users. I've been getting complaints from the Yahoo people that mail is delayed at times, or messages that come out of order. Looking at the mailq on the box, I can see there are plenty of emails stuck in the queue. I have all sorts of messages like this ... -Queue ID- --Size-- ----Arrival Time---- -Sender/Recipient------- 3576C540CB4 9917 Tue May 11 11:27:13 pcho-bounces(a)pchochat.com (host mta6.am0.yahoodns.net[67.195.204.74] said: 452 Too many recipients tnmpmscs (in reply to RCPT TO command)) <removed list of email addresses> (host mta6.am0.yahoodns.net[67.195.204.74] said: 421 [IPTS04] Messages from 74.112.73.65 temporarily deferred due to unexpected volume or user complaints - 4.16.55.1; see https://postmaster.verizonmedia.com/error-codes (in reply to end of DATA command)) <removed list of email addresses> 10932540D16 32765 Tue May 11 18:34:13 pcho-bounces(a)pchochat.com (host mta6.am0.yahoodns.net[67.195.228.111] said: 421 4.7.0 [TSS04] Messages from 74.112.73.65 temporarily deferred due to unexpected volume or user complaints - 4.16.55.1; see https://postmaster.verizonmedia.com/error-codes (in reply to MAIL FROM command)) <removed list of email addresses> (host mx-biz.mail.am0.yahoodns.net[67.195.204.83] said: 421 4.7.0 [TSS04] Messages from 74.112.73.65 temporarily deferred due to unexpected volume or user complaints - 4.16.55.1; see https://postmaster.verizonmedia.com/error-codes (in reply to MAIL FROM command)) <removed list of email addresses> (host mx-aol.mail.gm0.yahoodns.net[67.195.228.84] said: 421 4.7.0 [TSS04] Messages from 74.112.73.65 temporarily deferred due to unexpected volume or user complaints - 4.16.55.1; see https://postmaster.verizonmedia.com/error-codes (in reply to MAIL FROM command)) (host mta6.am0.yahoodns.net[67.195.228.111] said: 421 4.7.0 [TSS04] Messages from 74.112.73.65 temporarily deferred due to unexpected volume or user complaints - 4.16.55.1; see https://postmaster.verizonmedia.com/error-codes (in reply to MAIL FROM command)) <removed list of email addresses> So it seems that Yahoo/AOL keeps detecting my mailman3 server as either spam, sending too much email, or too many recipients. This email server is for our neighborhood community. Its moderated to join, and we know every single user on this list. We know it's not being reported as spam by our users. Anyone anyone shed some light on how to appropriately solve this issue?

Avoiding non-members to be saved.
by Guillermo Hernandez (Oldno7) 09 Aug '21

09 Aug '21

Hi all: Yesterday I had a problem with a private list. A spammer sent a mail forging one address that was a non-member (in fact was an "accept this no subscriber mails" from mailman 2.1 import) with very bad intentions and it was distributed. There were no list of "accept this non members" in the Postorius config (but I'm sure that that address was "accepted" in 2.1). To avoid this from any other non member address I deleted ALL non-members. I think it is solved now (deleting all and putting to hold just the non-members addresses that I would want to pass messages on) The fact is that any sender address of mails sent to the list is saved as a "non member", and it make me nervous as it will grow despite it is a legitimate message or not. Anybody knows if there is a per list config to avoid saving all that addresses as non members? o a overall config? I couldn't find anything about this in the config pages (or googling it) Thanks in advance. --

I need professional help to get virtualenv Mailman3 installation running
by John Seifarth 09 Aug '21

09 Aug '21

Hello, I have been running Linux mailman2 servers for about 10 years, and sendmail/postfix servers for over 20 years. I have a client who wants to upgrade to Mailman 3 from their current Mailman2 system. I wanted to avoid the disruption of an upgrade, so I implemented a series of test servers with different names (leaving the mailman2 server in production at its historical address) running Ubuntu 18 and Ubuntu 20, using the mailman3 packages (3.1and 3.2 respectively). I sort of got it running with mailman 3.2 on Ubuntu 20, but couldn’t get Hyperkitty archiving to work. Plus the fact that mail bounce handling isn’t implemented prior to mailman 3.3.2, I decided to install the latest mailman version available in a venv environment, using the instructions at https://docs.mailman3.org/en/latest/install/virtualenv.html I followed the instructions carefully using the same paths, and tracked down and fixed errors as each step progressed. I finally set up a WSGI server according to the instructions, searched for and found (fragmentary) instructions for setting up the Apache configuration, started the mailman3 and mailman web services, and now have no errors in the /opt/mailman/web/logs files, the /var/log/apache files, and in syslog. But when I try to connect via the Web, I get the message "Server error An error occurred while processing your request.” in my browser. No other clues. I’m completely stuck, and I need help to conclude this rapidly, the client really needs the new service up and running ASAP. I’m at the limit of my competence. I’ve been learning Python on and off (insufficient available time), and I installed Django and ran the tutorials. I still am woefully unskilled in the subtleties of a complex Python project like Mailman/Posterious/Hyperkitty, and I really need the help of an expert who can log into the server and see for themselves where the problem(s) are, and fix them. What I need is an experienced Python programmer, who has installed, run, and upgraded venv mailman3 installations. Of course, I will pay for this expertise, and charge it to the end client. In other words, I will pay you directly, and then I will worry about getting paid myself later. I am ready to pay €60/h for your skills, paid directly to your bank account, after receipt of your invoice. It shouldn’t be all that much work, since everything has been installed according to instructions, I’m just not a good enough Python programmer to get all the parts to work together correctly. It’s important to note that the end client is an organisation of European political parties, the virtual machine running the Ubuntu 20 server is hosted at OVH in France. Thus the professional with whom I would work should preferably also be based in the EU, and subject to EU law. Practically speaking, if anyone is interested, please send me a direct email with your email address and phone number, and then we can discuss how to do this practically in terms of SSH access, passwords, etc. Thanks for taking the time to read this, and I hope some Python Mailman pro can come to my aid.

Mailman3 stopped working after Upgrade to Ubuntu 21.04
by Thomas Möhle 08 Aug '21

08 Aug '21

Hey, I have set up mailman3 with mailman3-web on my mailserver and after upgrading to Ubuntu 21.04 my setup stopped working. I can see repeating log entries of mailman trying to reach something within hyperkitty and getting an error. The same constant repeating cycle of log entries is visible in my log files. I have attached my config files as well as the logfiles for mailman3 and mailman-web. As you can see, I'm not really getting many errors, yet within 5 seconds there are almost 2000 lines of log entries where mailman tries to reach something within hyperkitty over and over and over again. One thing I did to create an error message is start up both services, then edit a test list, that I created, in the web interface. This is the error you can find in the logs then: ERROR 2021-08-07 12:50:26,932 2343625 postorius Un-handled exception: HTTP Error 404: Traceback (most recent call last): File "/usr/lib/python3/dist-packages/django/core/handlers/base.py", line 113, in _get_response response = wrapped_callback(request, *callback_args, **callback_kwargs) File "/usr/lib/python3/dist-packages/django/views/generic/base.py", line 71, in view return self.dispatch(request, *args, **kwargs) File "/usr/lib/python3/dist-packages/postorius/views/generic.py", line 74, in dispatch return super(MailingListView, self).dispatch(request, *args, **kwargs) File "/usr/lib/python3/dist-packages/django/views/generic/base.py", line 97, in dispatch return handler(request, *args, **kwargs) File "/usr/lib/python3/dist-packages/postorius/views/list.py", line 301, in get primary_email = set_preferred(request.user, mm_user) File "/usr/lib/python3/dist-packages/postorius/utils.py", line 77, in set_preferred mm_user.preferred_address = primary_email.email File "/usr/lib/python3/dist-packages/mailmanclient/restobjects/user.py", line 57, in __setattr__ super(User, self).__setattr__(name, value) File "/usr/lib/python3/dist-packages/mailmanclient/restbase/base.py", line 131, in __setattr__ return super(RESTObject, self).__setattr__(name, value) File "/usr/lib/python3/dist-packages/mailmanclient/restobjects/user.py", line 145, in preferred_address response, content = self._connection.call(url, {'email': email}) File "/usr/lib/python3/dist-packages/mailmanclient/restbase/connection.py", line 127, in call raise HTTPError(url, response.status_code, urllib.error.HTTPError: HTTP Error 404: WARNING 2021-08-07 12:50:26,938 2343625 django.request Not Found: /mailman3/postorius/lists/test.lists.example.com/ Can anyone here help me debug this? I'm working on this problem for days now and can't seem to find a solution. Thanks so much in advance, Thomas

remove non members from a list
by Guillermo Hernandez (Oldno7) 06 Aug '21

06 Aug '21

Hi all: I need to remove all non members from a list. I know I can do it via Postorius, but it has to be done one at a time. (you can delete ALL suscribers but not all non members...) Anyone has a python recipe to do this? I've been searching and googling but I cannot find the way of doing it safely. And via DDBB there are more than one table involved and I'd rather not mess it all... Thanks in advance

UnpicklingError on mailman lists command

Hi all -- I'm getting the error below when trying to exec the "mailman lists" command. I've turned debugging on within my test mailman.cfg like so... [database] class: mailman.database.mysql.MySQLDatabase <snip> debug: yes [logging.database] level: debug path: dbmailman.log and can see a lot of info including the row(s) with each lists data returned in dbmailman.log.

web api
by Ethan Furman 04 Aug '21

04 Aug '21

Greetings again! Is there a remote API I can use to manage a list? One of the lists I manage has 1800 or so users, the vast majority of which have never posted, and I need to remove them (preferably not one by one). The list is meant to be actively used, so going forward I want to be able to unsubscribe anyone who hasn't posted in the last year. Both of those would be much more nicely done with a python script on my computer if I had a means to communicate with the mm3 server remotely. Any and all help appreciated! -- ~Ethan~

at the finish line of mailman3 docker, but can't sign in.
by bob B 02 Aug '21

02 Aug '21

I am trying to setup mailman3 in docker and have some questions, I can see the finish line :) i hope. I start my images and I can access the web,http://Servername.domain.com/postorius/lists/ and no list are there of course, but How do i sign in? I click the forget link and I have to enter in a email address. I put in the email address I added to the docker-compose.yaml but that does not wrok. I have these setup in the .yaml file. MAILMAN_ADMIN_USER: The username for the admin user to be created by default. MAILMAN_ADMIN_EMAIL: The email for the admin user to be created by default. I found this url http://Servername.domain.com/admin/login However I never set a password and here is no forget button, Basically once I have docker installed, and mailman3 up and no lists are available, How do I setup or/and sign in as admin? Also In docker how can I test sending mail? the command "mailman-web sendtestemail youremailid@domain" from the mailman-web container does not work. How can I make sure my containers can send and receive mail?

migration
by Dave McGuire 31 Jul '21

31 Jul '21

Hi folks. Some time ago, I set up mm3 and have been running a bunch of lists on it with great success. I was a long-time mm2 user, and while the differences are significant, I'm glad I made the switch. However, in what seems to have been a moment of insanity in retrospect, I installed mm3 from my OS' package repository. Yeah, I know, that was dumb. Now I'd like to migrate to a new server, and I'd like to install mm3 in the normal way. Is there a way that I can "dump" the configuration from an existing mailman3 server, and "import" it into a new instance? I'd really like to avoid re-doing all of the configuration, etc, as there are quite a few lists and everything is set up pretty much the way I want it. I would appreciate any advice from this learned group. Thanks, -Dave -- Dave McGuire, AK4HZ New Kensington, PA

Mailman lifecycle
by eugenio.jordan＠esa.int 30 Jul '21

30 Jul '21

Dear all. Perhaps this is a sort of dummy questions for software supported by the Community, my apologies in advance. I have been asked on information related to the end of life of support for 3.1 version, and I was wondering whether you could please provide some insights on how the Mailman life cycle is conceived. For instance, are there periodically planned releases, say 1 per year? If so, will you please confirm how long we are to expect the previous versions to be maintained? Thanks so much in advance for the help. Best regards.
