Moving mm3 -> mm3 to different host
by Axel Rau 19 Oct '23

19 Oct '23

Hi all, There are lots of threads for mm2 -> mm3 moves, but only one thread mm3 -> mm3. Some time ago, I found a post from Mark, explaining the steps, but I can't find it again. I have created a working mm3 installation on the new host with both mailman and mail-web dbs imported. hyperkitty archive seems to in the db. What are the next steps to complete the transfer? - rsyncing messages, lists and templates to new host - Setting up DNS CNAMES to the new server - Adapting exim to accept mails to the aliased domain - Can I keep the old listname, with the old domain name? -What else has to be done ? Thanks, Axel -- --- PGP-Key: CDE74120 ☀ mobile: +49 160 7568212 computing @ chaos claudius

Unusual behavior: Standard discussion lists with prefix are sometimes having prefix *dropped*
by Thomas Ward 19 Oct '23

19 Oct '23

I noticed some unusual behavior in Mailman3 stable release on PyPI and such. Namely, there are instances where replies are being processed and the prefix tags are simply being **lost** and dropped by Mailman3, instead of being properly prepended where they're supposed to go. Is this a known bug or does it need its own bug in the gitlab tracker? Thomas

Thread IDs on messages incrementing per reply?
by Thomas Ward 19 Oct '23

19 Oct '23

Trying to use the thread prefix component to *tag* thread IDs in a system, but not increment per message. It looks like replies are being received and then thread prefixes are getting incremented. "[Test-%07d]" is the prefix I"m using on a given test list, but we want it to increment by thread ID and *not* per message. (6 messages for instance have been sent, two were replies to [Test-0000004] and though the system properly archived it in the same conversation, it still incremented the digit counter). Is there a way to achieve this in Mailman3 without me having to write some kind of custom code for this? Thomas

Rootkit issues
by Kyriakos Terzopoulos 18 Oct '23

18 Oct '23

Hi, After installing mailman and using it for a few days, I got several complaints from my hosting company for abuse. After checking the server, it seems that there is a rootkit (Blitz) running with the mailman process. Has anyone come across this issue? Are there any specific steps to secure the mailman user?

Simple ubi8/mailman3 container image
by Jered Floyd 17 Oct '23

17 Oct '23

Abhilash maintains a very complete and well-documented container deployment for Mailman 3, but when I was setting up my environment a few months ago I wanted to build on top of RHEL 8 as well as use a database instance shared across multiple applications. So I ended up creating a bare-bones container image that suited my needs and was closer to just doing a simple local install, but keeping the isolation, reproducibility, and rollback benefits of running as a container. I've been meaning to polish it up and share in case it is useful to others, but finally recognizing that I likely won't get to that soon I've just put it on GitHub here: [ https://github.com/jeredfloyd/mailman-container | https://github.com/jeredfloyd/mailman-container ] Doing a "podman build" of this should result in a container image that is very much like the result of doing a venv install. This uses the Red Hat Universal Base Image (UBI), which can be freely redistributed, gets upstream security updates, and is eligible for support on a paid RHEL subscription. --Jered

Hello, Users who have Outlook receive an attached txt file with the name ATT00001.txt when they receive an email from a mailman3 list. Is there a way to stop it from sending this file? Thank you so much

Post installation issues (recipients refused) with Exim4 in a virtual host environment
by Kyriakos Terzopoulos 17 Oct '23

17 Oct '23

Hi, I have set up (I believe successfully) and configured the following in a Virtualhost environment (with HestiaCP): - A record for lists.mydomain.com - Venv - Mailman core - Mailman web (run migrate, collectstatic, compress, compilemessages) Postorius - gunicorn, hyperkitty - Nginx - SMTP exim4 conf I can see Posrorius and I have logged in and created my first mailing list: [image: Screenshot 2023-10-11 at 10.57.31 AM.png] My issue is that even though I have subscribed to my list as you can see above, I am not receiving the confirmation email.

Setting up on ubuntu server 22.04
by Kyriakos Terzopoulos 15 Oct '23

15 Oct '23

Hi guys, I have an Ubuntu 22.04 server running on a Hetzner machine, with HestiaCP (Exim4) on it. I cannot for the life of me start the service of mailman3 core. Following the installation tutorial I have tried with the venv approach and I am having the following issues: 1) It is not clear to me whether the mailman configuration should be outside venv (and outside the mailman shell). 2) For the above reason I have created a config file: /etc/mailman3/mailman.cfg and the mailman3 service outside venv. When starting the service I get the following: ImportError: cannot import name 'path' from 'importlib_resources' (/opt/mailman/venv/lib/python3.10/site-packages/importlib_resources/__init__.py) I've set up the database, the mailman user and the virtual environment. I know I am missing something here (e.g. Python version? other dependencies?). In general would it be better or/and easier to set this up on a new machine in my Hetzner cloud e.g. on Debian which seems to have packages of mailman available? Thanks in advance for all your help. Kyriakos

Memory usage cgroup and free -m
by golden_rock＠hotmail.com 12 Oct '23

12 Oct '23

Hi, Currently the mailman3 cgroup slice uses up to 875MB: Control Group Tasks %CPU Memory Input/s Output/s system.slice/mailman3.service 16 0.1 875.3M - - Is 875MB a normal expected amount, or more than expected? To confirm that this is truly used and not "cached", I use the new Available column from the "free -m" output, which is the pre-computed available memory for a new process, added in recent years. The output of free -m under the Available column when mailman3 is running is : 161 MB When I stop the mailman service, the output of free -m Available column goes up to: 1071 MB Showing that the 875MB previously were not available for release for new processes. If I start mailman service again, the output of free -m Available column goes back to : 325MB and will be reducing gradually over time. I looked around on posts, documentation and others, but didn't find guides related to reducing RAM usage, is that a possibility or is this memory usage expected?
