by Stephan Krinetzki June 7, 2022

June 7, 2022

Hello all, our Mailman3 has over 7GB of bounces in its bouncedir. I noticed that some messages there are already over 3 years old. Now my question: Is there a way to remove the old bounces?

Can login at /admin, but cannot login at the account/login page.
by pabsta＠gmail.com May 11, 2022

May 11, 2022

Hi All, thanks for your contibution to opensource softwares. I have done the installation walkthrough on the wiki page (thanks to Brian Carpenter) and I am almost there. I can run the three services and they provide the relevant web interfaces (admin, postorius, hyperkitty). In comparison to the walkthrough, I did two changes; First, I used different port numbers , as it would otherwise conflict with other services on the server. Second, I disabled the social accounts authentification mechanisms. I am still running on sqllite, as I am still testing things (one task at a time). Using my "superuser" credentials, I can log to the admin section in a fraction of a second. The server response time is less than one second. Once logged in, I can navigate through all the site as an authenticated user, including in the postorius pages related to list management. The services work normally. However, if logout and attempt to login from the postorius website, I get a « 502 bad gateway » error after roughly 30 seconds. The logs in Systemctl for gunicorn register a "DIGEST-MD5 common mech free" error message and the nginx error logs just show a connection drop: 2021/08/12 18:11:09 [error] 26026#26026: *31 upstream prematurely closed connection while reading response header from upstream, client: [ip redacted], server: [domain redacted], request: "POST /accounts/login/ HTTP/2.0", upstream: "http://127.0.0.1:8006/accounts/login/", host: "[domain redacted]", referrer: "https://[domain redacted]/accounts/login/?next=/mailman3/lists/" Two additional clues may help understanding what is going on: 1- If I attempt to login with improper credentials, the services respond normally, and I get the expected red box with "invalid credentials" message on the postorius page. It is only when proper credentials are given that the connection fails. 2- If I attempt to register a new email adress, the services also fail to respond (although with no DIGEST-MD5 message registered). It thus seems to be a post "POST" problem, but what puzzles me is that it is not an issue for the admin page. Below the relevant sections of my settings.py page. The skipped ([...]) sections are as in the walkthrough files. In particular, the AUTH_PASSWORD_VALIDATORS, the EMAIL_BACKEND are as is and the "USE_X_FORWARDED_HOST" is still commented. ##Settings.py [...] # SECURITY WARNING: keep the secret key used in production secret!

Lessons learned and a couple little gotcha for newbies
by William Oliver April 13, 2022

April 13, 2022

I just finished, with great help from Mark Sapiro on the list, a new installation of mailman3. I used the instructions at https://docs.mailman3.org/projects/mailman/en/latest/src/mailman/docs/insta… and https://docs.mailman3.org/en/latest/install/virtualenv.html There were a couple of gotchas that I didn't see well documented. 1) I got the error django.template.library.InvalidTemplateLibrary: Invalid template library specified. ImportError raised when trying to load 'hyperkitty.templatetags.decorate': cannot import name 'escape_html' from 'mistune.scanner' (/opt/mailman/venv/lib/python3.9/site- packages/mistune/scanner.py) when I ran 'mailman-web migrate' The fix was trivial: I just added the lines: from mistune.util import escape_html from mistune.util import escape_url to /opt/mailman/venv/lib/python3.9/site-packages/mistune/scanner.py It's not hard to search for those definitions, but if someone doesn't know a smattering of python, it might not be obvious. 2) Similarly, migrate (using postgres) also gave the error: File "/opt/mailman/venv/lib/python3.9/site- packages/django/db/backends/postgresql/utils.py", line 6, in utc_tzinfo_factory raise AssertionError("database connection isn't set to UTC") I was able to find a discusson of this one at https://stackoverflow.com/questions/68024060/assertionerror-database-connec… which had me downgrade to an older version of psycopg2-binary: pip install psycopg2-binary==2.8.6 There might be a different fix, but this worked. 3) When I ran the test "uwsgi --ini /etc/mailman3/uwsgi.ini" I got the error: ModuleNotFoundError: No module named 'settings' This was also trivially fixed by adding the path: export PYTHONPATH=$PYTHONPATH:/etc/mailman3 in /opt/mailman/.bashrc 4) Sometimes when I rebooted the machine, when I ran 'systemctl start mailman3' I'd get the error that mailman wouldn't start because the lock was stll there. I never could figure out where the lock was, so I worked around it by replacing ExecStart=/opt/mailman/venv/bin/mailman start with ExecStart=/opt/mailman/venv/bin/mailman start --force in /etc/systemd/system/mailman3.service I'm sure there's something bad about doing that, but it works for me, so far. 5) I had a problem with mail to outside people not being delivered while mail to the local host was delivered. It turned out that this was because in my mailman.cfg I had "smtp_host:my.listserver.tld when it should have been localhost. The error was "relay access denied." To fix this, I had to add my.listserver.tld to "mynetworks" in /etc/postfix/main.cf, ie change: mynetworks = 127.0.0.0/8 10.0.0.0/24 to mynetworks = 127.0.0.0/8 10.0.0.0/24 111.222.333.444 <--- my ip address However, Mark Sapiro (a God) told me this was because I had changed a line in the [mta] section of mailman.cfg. I had changed smtp_host: localhost to smtp_host: mydomain.tld Here's the thing. The reason I did this was because the instructions at https://docs.mailman3.org/en/latest/config-core.html give this as their model: [mta] incoming: mailman.mta.postfix.LMTP outgoing: mailman.mta.deliver.deliver lmtp_host: mail.example.com lmtp_port: 8024 smtp_host: mail.example.com <---- not localhost smtp_port: 25 The instructions are good, but there are a few places where one size does not fit all, I guess. 6) A second error in delivery to outside addresses resulted in an "Access denied" error. A search on the internet revealed that this had to do with (for me) smtpd_recipient_restrictions in postfix. See, for instance: https://know.mailsbestfriend.com/postfix_error_relay_access_denied_noqueue_… Changing this fixed things. I'm not sure, but I think this shows up mostly with installations that include dovecot. 7) If you are using virtual domains in postfix, you need to use the "unusual postfix configuration" in https://docs.mailman3.org/projects/mailman/en/latest/src/mailman/docs/mta.h… virtual_alias_maps = hash:/path-to-mailman/var/data/postfix_vmap 8) You need to manually set the local virtual host for mailman3. Somehow, I got the impression from the installation instructions that this was done automagically to the default x.mydomain.tld if your domain is mydomain.tld. It doesn't. 9) Follow the instructions verbatim, and follow them in the order provided. I installed postfix and nginx out of order, and it did OK, but once you get into the python virtual environment, it is easy to miss something if you don't do it in order. 10) Jot down lots of notes. This is one of the more complicated installations I've done, mostly because it involved configuring a zillion packages to talk to each other: Postfix, nginx, postorius, hyperkitty, django, and others (I'd never heard of "whoosh" or "sass" for instance). All of these can be unforgiving with configuration errors. The default installation instructions assumed a number of packages I'd never used. I'm an apache/dovecot/mysql kind of person, and I had to switch to nginx/postgres to use the instructions as the written defaults. I'm sure I could have used apache and mysql, but it would mean trying to figure out what didn't work without following the installations verbatim. I'd never even heard of postorius, hyperkitty, or django. So, it was easy to get confused a bit. Taking notes of changes I made was important in being able to back out of disastrous choices. Plus, once I'd installed it on one machine, I sat down and installed it on another machine, and it was very useful to have written down how I fixed an issue when it came up again -- and I didn't remember exactly what I had done. 11) Make multiple sequential backups of configuration files. I went down a couple of paths I shouldn't have gone down. For instance, with the vmap issue, I got it in my head that it was a postfix configuration issue, not a mailman issue. So I kept changing things in postfix. Once I was told that it was in *mailman* I had to set the virtual host, I needed to back out of about 8 tweaks I'd made to main.cf in /etc/postfix. If I hadn't been making main.cf.backup.01, main.cf.backup.02, etc. I would have had to spend another few hours trying to remember what inappropriate changes I had made. This is particularly true for me because I am not a great typist, and when I try to retype something to back out, there's a reasonable chance I'll mistype something and it still won't work. With these backups, I don't have both manually back out of things *and* proof my typing again and again. It's a lot easier to delete backups once things are working than to try to remember what you did late at night after a couple of bourbons. 12) Choose one set of installation instructions and follow it. Don't try to mix instructions from different tutorials unless you really know what you are doing. I didn't. For instance, there's a different set of mailman3 installation instructions at: https://wiki.list.org/DOC/Howto_Install_Mailman3_On_Debian10 It does things a little differently. It's useful to look at that when you are debugging why something's not working, but you can get into some trouble trying to do both installations at the same time -- which I found myself doing when something wasn't working. It didn't help. billo

out queue backlog and delivery rate
by dancab＠caltech.edu April 11, 2022

April 11, 2022

We experienced an issue where our upstream mail protection gateway had an issue for a few hours. As a result out Mailman system was inundated with hundreds of messages within half an hour. Mail delivery is continuing at a snails pace and it is now 4 hours behind. I noticed that the system isn't overloaded either via CPU or Memory. It's just slowly "working on it". Are there rate limits that can be tuned for Mailman queues such as the "out" queue? Could this be IO related somehow? I'd expect there to be a CPU spike in that case. Please advise. Thanks in advance. ---- Dan Caballero Systems Administrator Academic Computing Solutions IMSS - Caltech https://imss.caltech.edu Is there anyway to

Active archivers and archiving and thread question.
by bob B March 31, 2022

March 31, 2022

Digging into the mailman3 world, and want to check my logic... We normally don't use archives, so I have "archive policy" set to "Do not archive this list" for our lists. However, the "archives" button is still there on the list info page, and if users go into it, they don't see anything, But they can click "start a new thread" which sends a message to the list, but since archiving is turned off, that message does not show up there. Am I understanding that correctly? if I have "Active archivers" disabled, that hides that area from the users, correct? Any reason why these are separated? why have an active archiver, if archiving is turned off -OR- archives are turned on, but no active archiver?

Problem with redirection when entering alias without a / at the end
by Jens Günther March 31, 2022

March 31, 2022

Hey there, I'm using Apache2 as the webserver, configured https://mailman.xyz.de as Web host. When I want to get to Mailman Starting Page now I need to Enter the following URL: https://mailman.xyz.de/mailman3/ to be directly redirected as expected to https://mailman.xyz.de/mailman3/postorius/lists/ -> works. Problem: When leave out the slash at the end and I ONLY enter the following URL: https://mailman.xyz.de/mailman3 -> then I'm wrongly redirected to a page, taht does not exist: https://mailman.xyz.de/mailman/postorius/lists/ -> 404 Where can I change this misbehaviour? In Apache-conf everything seems as it'S in the docs, for the vHost I do not have any other custom settings. Thank you in advance. By the way: Is there an easy way to redirect directly from https://mailman.xyz.de to https://mailman.xyz.de/mailman3/postorius/lists/ -> what would be a possibility for that?
