Problems after update to mailman 3.3.7
by Guillermo Hernandez (Oldno7) Dec. 7, 2022

Dec. 7, 2022

I've getting the most strange behaviour after update to last releases. In one of my mailman3 servers, the messages doesnt reach for some lists (the five last ones) the update have not showed any error but in the var/data for the lmtp and vmap postfix files mailman does not create aliases for that last 5 lists. Any message addressed to them is returned with a "no such user" error. If I create a new list the system or restart mailman runners it shows this error: Generating MTA alias maps /usr/local/lib/python3.9/site-packages/pymysql/connections.py:799: UserWarning: Previous unbuffered result was left incomplete warnings.warn("Previous unbuffered result was left incomplete") I did a CHECK TABLE on mailinglists table but all seems ok. I tried reinstalling PyMySQL, but has no effect. (well, I tried reinstalling all) It seems to me that something is preventing creation of that aliases, an then the that last five lists are unreachable. I have no clue of what to do now and I'm driving crazy. Some direction to look for will be much apreciated. Thanks in advance. P.S.: I can access via postorius/hyperkitty to the archives of the lists that are unreacheable. -- ___________________________________________ Mailman's content filtering has removed the following MIME parts from this message.

Strange messages after upgrading Mailman3
by Allan Hansen Dec. 6, 2022

Dec. 6, 2022

Hi all, I have been getting a few of these messages after my Mailman 3 was upgraded: "The content of this message was lost. It was probably cross-posted to multiple lists and previously handled on another list." The messages appear to come from list members and are distributed to the relevant lists, but with nothing of the original contents. They have appeared on different lists with, apparently different senders (unless spoofed). Other messages are going through the system unchanged. Anyone has any ideas? Yours, Allan

Issues encountered while upgrading to 3.3.7
by Odhiambo Washington Dec. 5, 2022

Dec. 5, 2022

Hello everyone, I am starting a new thread on this so that the issues I encountered do not get mixed up with the other discussions. Over the weekend I upgraded an MM3 installation to the latest versions of the components. I started off by creating a new venv, installing and then migrating the configurations and the scripts. In the end, I ended up with MM3 Core ==3.3.7, postorius==1.3.7, HyperKitty==1.3.6, django==4.1.3. 1. SQLAlchemy - At the stage where one runs 'mailman info', I encountered the first error: : sqlalchemy.exc.NoSuchModuleError: Can't load plugin: sqlalchemy.dialects:postgres This is solved by a change in mailman.cfg so that the URI starts with postgresql:// instead of postgres://. SQLAlchemy used to accept both but has removed support for the postgres name. <https://github.com/sqlalchemy/sqlalchemy/issues/6083#issuecomment-801478013> 2. Django==4.x At the point of running the post-update processes, particularly the "migrate" bit, I got the following error: : ImportError: cannot import name 'url' from 'django.conf.urls' (/opt/mailman/mm/venv/lib/python3.9/site-packages/django/conf/urls/__init__.py) I understand this is a consequence of the django.conf.urls.url() having been deprecated starting version 3 and has been removed in version 4 of Django. https://docs.djangoproject.com/en/4.1/releases/4.0/#features-removed-in-4-0 The upgrade process seems to have brought in the newer version of Django because now I have 4.1.3 up from 3.x If anyone wants, I found an elaborate explanation at https://bobbyhadz.com/blog/python-importerror-cannot-import-name-url-from-d… . My Google-fu found suggestions that in urls.py, I should import re_path and use it, or alias it for url for the migrate to work. The solution I used was to alias url to re_path, but I am considering just doing away with url altogether. Not sure which is the better option between using re_path or path. So here is the patch I have used: (venv) mailman@lists:~/mm$ diff -u urls.py.bak urls.py --- urls.py.bak 2022-12-03 12:20:28.028090659 +0300 +++ urls.py 2022-12-03 12:36:20.298875624 +0300 @@ -17,7 +17,8 @@ # Postorius.

Handling of spam
by Eggert Ehmke Dec. 5, 2022

Dec. 5, 2022

I have a mailing list that is open to nonmembers. Sometimes we get spam on that list. I have a working spamassassin/amavis spam filter on the system. Now comes the strange part: sometimes a spam message is put into a multi-part message and forwarded to the list owner (me). This multi-part message contains the message marked as spam, but is not marked as spam itself. The origin of those message is the bounces address of the list. So my first question is: where can those messages be generated? I can provide the message header, but it would contain a lot of details of my server. Cheers, Eggert

Is there an easy way to set Reply-To to a lists owner?
by Martin Lorenz Dec. 4, 2022

Dec. 4, 2022

Hi again, now, that Mailman3 is running smoothly I have a new question. We have a bunch of lists, which are only used for spreading news. Now the admin of theses lists (who happens to be my wife) asked me, if it was possible to change the settings such that all replys to one of these lists can only be sent to herself (i.e. the owner address) instead of being held for moderation. I thought of setting Reply-To to something like <list-owner> by "simply" entering a Variable into this field, instead of using the admins/owners literal email-address. Is this possible? Or is there another way of achieving the goal? TNX Greetings Martin

Weird startup problem after upgrade
by Odhiambo Washington Dec. 3, 2022

Dec. 3, 2022

I am facing an odd situation in which MM3 doesn't start successfully on reboot, but I can start it manually. This is a venv install. This started after I did an upgrade (pip install --upgrade mailman postorius hyperkitty mailman-hyperkitty) followed by the requisite collectstatic|compress|compilemessages|migrate post-update commands. Secondly, it appears that the upgrade did NOT change the versions for the upgraded components - postorius=1.3.6, hyperkitty=1.3.5, Mailman Core Version=3.3.5. I was expecting the version to all bump up to the latest. Thanks in advance for any insights into what could be causing this. wash@lists:~$ systemctl status mailman3 × mailman3.service - GNU Mailing List Manager Loaded: loaded (/etc/systemd/system/mailman3.service; enabled; vendor preset: enabled) Active: failed (Result: timeout) since Fri 2022-12-02 18:58:13 EAT; 9s ago CPU: 25.241s Dec 02 18:58:12 lists mailman[1637]: File "/opt/mailman/mm/venv/lib/python3.10/site-packages/mailman/core/runner.py", line 114, in signal_handler Dec 02 18:58:12 lists mailman[1639]: for atexit_call in reversed(_threading_atexits): Dec 02 18:58:12 lists mailman[1639]: File "/opt/mailman/mm/venv/lib/python3.10/site-packages/mailman/core/runner.py", line 114, in signal_handler Dec 02 18:58:12 lists mailman[1637]: raise RunnerInterrupt Dec 02 18:58:12 lists mailman[1639]: raise RunnerInterrupt Dec 02 18:58:12 lists mailman[1637]: mailman.interfaces.runner.RunnerInterrupt: Dec 02 18:58:12 lists mailman[1639]: mailman.interfaces.runner.RunnerInterrupt: Dec 02 18:58:13 lists systemd[1]: mailman3.service: Failed with result 'timeout'.

Mailman web interface / uwsgi
by Jan Eden Nov. 28, 2022

Nov. 28, 2022

Hi, I followed the installation instructions at https://docs.mailman3.org/en/latest/install/virtualenv.html#virtualenv-inst…, which thankfully shielded me from configuring the Django applications for the web interface manually. All Django applications (postorius, hyperkitty, haystack etc) are loaded via mailman_web/settings/base.py, which is in turn referenced by the top-level settings file in /etc/mailman3. uwsgi is linked to mailman_web via /etc/mailman3/uwsgi.ini. So far, so good. I do not want to dive into the interaction between the various components and just want to switch from a http socket (http-socket = 0.0.0.0:8000) to a file socket (socket = /opt/mailman/mm/var/mailman.sock). After making this change in /etc/mailman3/uwsgi.ini, I applied it in the nginx proxy configuration proxy_pass http://127.0.0.1:8000; → proxy_pass http://unix:/opt/mailman/mm/var/mailman.sock; and received an error message (as expected): 2022/11/25 18:39:12 [error] 2978606#2978606: *3 upstream prematurely closed connection while reading response header from upstream, client: 37.201.155.65, server: lists.eden.one, request: "GET /mailman3/lists/ HTTP/2.0", upstream: "http://unix:/opt/mailman/mm/var/mailman.sock:/mailman3/lists/", host: "lists.eden.one" There are obviously a couple of places where the http-socket on port 8000 is referenced (e.g. mailman_web/settings/mailman.py, /opt/mailman/mm/hyperkitty.cfg). Is there an overview of the required changes when using a different (file) socket? Related question: My own (much simpler) Django applications use the following (e.g. in mysite_nginx.conf): upstream django { server unix:///private/tmp/mysite.sock; } location / { uwsgi_pass django; } instead of the "http://unix:/..." notation I tried for Mailman above. Is there any difference between the upstream/uwsgi_pass combination and the proxy_pass variant? Thanks, Jan

Default list styles
by Jan Eden Nov. 27, 2022

Nov. 27, 2022

Hi, the list creation web interface offers three list styles (announce, ordinary, ordinary w/ private archive). When selecting the announce style, I would expect a different default message acceptance setting for members (i.e. reject), because this is how an announce list should work. In practice, a list created with the announce style is configured just as an ordinary mailing list (as far as I can see in the web interface, and according to the handling of a test message sent by a regular member of an announce list). What am I missing here? - Jan

Mailman3 not able to deliver emails sent through list, but moderation notifications
by Daniel Böhmer Nov. 27, 2022

Nov. 27, 2022

Hello Mailman users, I've been using Mailman2 for 10+ years and have recently upgraded to Debian Buster with Mailman3. I've tried to setup Mailman3 similarly but it fails to deliver emails sent through a list. I do receive all moderation notifications at the same time. During startup /var/log/mailman3/mailman.log receives: > Cannot connect to SMTP server localhost on port 25 but I've made sure postfix is listening on *:25 for both IPv4 and IPv6. When sending a message to a list the same file receives: > Nov 25 11:38:14 2022 (70371) ACCEPT: <MESSAGEID@HOST> (message ID and host redacted) and nothing else happens: no more log messages, Postfix logs the email sent TO Mailman but doesn't log anything about emails sent BY Mailman. If Mailman fails to send emails via Postfix I'd expect it to log error messages but it doesn't seem to do so. I found this article stating the the SMTP error message might be misleading: https://blog.tfiu.de/mailman3-cannot-connect-to-smtp-server-localhost-on-po… How to further debug this? What could be wrong with my Mailman3 instance and how to fix it? Kind regards Daniel Böhmer
