How to debug DMARC check?
by Gilles Filippini 03 Sep '23

03 Sep '23

Hi, I've been running a dockerized mailman3 server for several years with DMARC mitigation set to conditional. I use the 0.4 version of the mailman3 docker images. Recently I had to update my network configuration to prevent spammers using IPv6 to circumvent the no-relay configuration of my exim4 server. Previously, I had both exim4 and mailman3 on the same docker bridge 172.19.0.0/16 and exim4 was configured to relay email from this network only. There was no problem regarding DMARC mitigation : most of the emails didn't need to be altered. Now I have added an internal docker network 172.29.0.0/16 and configured exim4 to relay from this internal network only. Since this network is not accessible from the host, IPv6 spammers are blocked (*). But since this modification mailman alters every emails with DMARC mitigation. Any hint how to debug this issue? Thanks in advance, _g. (*) With IPv6 incoming connexions mailman docker replaces the client address with the IPv4 address of the host one the bridge network: 172.19.0.1.

Add date stamps to django (I think) logfiles?
by kjohnson＠eclypse.org 01 Sep '23

01 Sep '23

The webserver and archive part of mailman writes some logfiles on my system with entries like: 17:19:05 [Q] INFO Process-1 guarding cluster twenty-pluto-arizona-pasta 17:19:05 [Q] INFO Process-1:4 pushing tasks at 2831 17:19:05 [Q] INFO Q Cluster twenty-pluto-arizona-pasta running. These seem to match this format in settings.py: 'format': '%(levelname)s %(asctime)s %(process)d %(name)s %(message)s' except that I would expect asctime to have a date attached. A pointer to relevant documentation would be very much appreciated. Thanks. Ken

Installing Mailman3 on Debian Bullseye
by Franklin Weng 30 Aug '23

30 Aug '23

Hi, After several times attempts I finally successfully build a (reliable enough) mailman3 instance on Debian. I had a blog article describing how I did it. Maybe there were something you find it ridiculous, but they are all what I found important and may not be shown in the current documents. https://blogs.slat.org/node/1012 Hope this helps. Franklin

log rotation in maxking-docker-version
by Jens Günther 27 Aug '23

27 Aug '23

Hey there, while checking some logs I was realising that there is no log rotation and some of them piled up to 5GB over the past year(s). Does anybody know how to activate it (if it's possible) or ... Ok, I found a clue and it's still open :-) https://github.com/maxking/docker-mailman/issues/535 -> does anybody have a different approach? Regards, Jens.

Can't start mailman after reboot.

I have successful rebooted my computer server several times, and mailman has always started without a problem Now mailman won't start. See below. I tried to see if it was a problem with mysql. But I can successfully connect to the sql server using the mailman username and password, from the command line. What else can I try???

Only allow users to subscribe from certain domains
by bob B 23 Aug '23

23 Aug '23

Does Mailman have anyway to just allow users to subscribe themselves to a list from certain domains... ie any user from test.com or test2.com I do not believe this exists, but have a list manger who is asking. I feel they will have to either, approve all requests, or have a web frontend built that could filter that out and then send the subscribe commands in the backend. Thanks

applying patch 1130
by David Newman 22 Aug '23

22 Aug '23

Please forgive a dumb question from a non-programmer: How to apply the !1130.diff patch to a venv installation? https://gitlab.com/mailman/mailman/-/merge_requests/1130 I am looking to upgrade Debian 11 to 12. The latter uses python3.11, which no longer has a dependency on importlib_resources. As a result, MM3 won't start unless all references to importlib_resources instead call importlib.resources, now part of stdlib. I tried patching all importlib.resource references by hand, and MM3 starts – but that can't be the "right" way to do this. Also, the diff references a src directory that doesn't exist under /opt/mailman. Thanks in advance for patching clues. dn

importlib_resources issue?
by Dave McGuire 21 Aug '23

21 Aug '23

Hi folks, I'm trying to test a fresh venv-based install from this procedure: https://docs.mailman3.org/en/latest/install/virtualenv.html Platform is SmartOS (Solaris 11) with Python 3.10. The installation goes fine, but initial startup bombs with: ImportError: cannot import name 'path' from 'importlib_resources' (/opt/mailman/venv/lib/python3.10/site-packages/importlib_resources/__init__.py) I assume this is related to importlib_resources moving into stdlib at some point. Is there a reasonable way around this? Thanks, -Dave -- Dave McGuire, AK4HZ New Kensington, PA

Ansible role to install Mailman3
by samuel.d.darwin＠gmail.com 04 Aug '23

04 Aug '23

Hi, Before installing the Mailman Suite, I searched on https://galaxy.ansible.com/ for Ansible roles that might automate the whole process. https://github.com/galaxyproject/ansible-mailman3 turned out to be quite good. However, it was slightly out-of-date. I cloned it, made a few bug fixes, and corrected linting errors. Then, going further, added optional basic installations of Nginx, Postfix, PostgreSQL into the role. If anyone is installing Mailman they are welcome to try it out. https://github.com/cppalliance/ansible-mailman3 Now, I see there was a discussion on this very list about https://github.com/rivimey/ansible-mailman3 which was also a fork of natefoo's repo. What are the differences? As Stephen Turnbull wrote: "her (rivimey's) setup may be more complicated than most folks need (IIRC, she has a multi-homed setup with Mailman core, Postorius, and HyperKitty on three separate IPs on a separate subnet in the DMZ, while Mailman was really designed for three Mailman applications running on the same host, along with the database server and MTA)." My version of the role didn't follow the tactic of "three separate IPs on a separate subnet in the DMZ". Mainly, it adds postfix and postgres. Fixes small errors. Also, in a git branch of the repository named mailman3-core, I removed all the web code, so there is a version of the role that only installs core. We will use that while bundling the web components into another Django app, already deployed with docker. There is an open question about maintenance. Among the three roles mentioned here, which is being actively kept up-to-date? Perhaps there are no guarantees from any of them. At this instant in time, https://github.com/cppalliance/ansible-mailman3 is the most recent. Would it make sense to mention these roles in the official documentation? Not sure. Installing mailman3 is complicated and because of that, is a good fit for Ansible.
