Strange URL in error message
by waps＠tantalus.jena.thur.de July 18, 2024

July 18, 2024

(Debian 12) I have the problem that the hyperkitty archive is empty. The file /var/log/mailman3/mailman.log show sometimes the message urllib3.exceptions.MaxRetryError: HTTPSConnectionPool(host='www.XXXXX-project.demailman3', port=443): Max retries exceeded with url: /hyperkitty/api/mailman/archive (Caused by NewConnectionError('<urllib3.connection.HTTPSConnection object at 0x7fa48b43a910>: Failed to establish a new connection: [Errno -2] Name or service not known')) (there is a slash missing between 'project.de' and 'mailman3'). My goal is, of course, to have an running archive. But I think the error message could be a hint about the reason) Do you have an idea what can I do about this?

deployment recommendation(?)
by noc＠iem.at July 18, 2024

July 18, 2024

(sorry, if this comes in double; i sent the same mail yesterday, but it seems it didn't make it (i did check the archives); so i'm re-sending via the webinterface) hi, it's summer here in europe, and students have left the campus. so - like every summer - I ponder on the idea of migrating our old mailman2 instance that has served us for the last twenty years to a new and shiny mailman3. and - like always - i'm a bit unsure about the best way to proceed to find the optimum deployment strategy for a long-running (decades) medium-sized (our largest list has ~1800 members) installation. one of our primary objectives is receiving *security updates*. we also would like to stay on top of development (that is: use the latest and greatest *stable* mailman3 release). in my heart i am a Debian person, so my mailman2 installation just used the Debian packages. the new deployment machine, will be Debian based as well. now https://docs.mailman3.org/en/latest/install/install.html lists three options: # Debian packages this is what I would normally pick, but: my past experience with mailman3 in Debian was... rather suboptimal. (my current Debian box running mailman3 is frozen at Debian/buster ("old-old-stable") because of mailman3). i see that the packages in current Debian/stable ("bookworm"), are lagging slightly (3.3.8, rather than 3.3.9), though that's to be expected from a distro with stable releases. otoh, Debian/unstable still ships 3.3.8, which is a bit disappointing. in any case, the really nice thing about (Debian-official) Debian packages is that they are typically - stable - guarantee an upgrade path between releases # Docker packages this is of course the simplest from a deployment perspective, but then i'm a bit worried about the security perspective. in my perception, docker deployments tend to get installed and then forgotten, and while the host OS keeps getting updates, the docker images are just left as is. so they tend to get stale. i would like to know how this is handled # virtualenv this is the deployment method recommended in the docs. however, it doesn't say why this method is any better than the others. also, the website says that it was last updated in 2019, so: is this recommendation still relevant? personally i do not have much experience with deployment of long-running software in virtualenv, and i'm esp worried a bit when it comes to switching python releases (which will happen multiple times in the next few years) i use virtualenv all the time for my pet projects, but there it doesn't matter much, if the venv breaks: i just delete it and start from scratch. but those are not long-running services. so: what are the drawbacks, limitations, advantages and benefits of the various deployment methods? i'd really like to make the switch this year! gmfasdr IOhannes

Setting PYTHONPATH in the virtual environment installation
by Keith Christian July 15, 2024

July 15, 2024

Before switching from a "git clone" installation to the virtual environment install, "/home/mailman3/mailman/src/mailman" was recommended as the PYTHONPATH setting. Here are some paths that exist in the Mailman3 virtual environment on the server in question: /opt/mailman3/venv/lib/python3.9/site-packages/mailman/archiving /opt/mailman3/venv/lib/python3.9/site-packages/mailman/archiving/__init__.py /opt/mailman3/venv/lib/python3.9/site-packages/mailman/archiving/__pycache__ /opt/mailman3/venv/lib/python3.9/site-packages/mailman/archiving/docs /opt/mailman3/venv/lib/python3.9/site-packages/mailman/archiving/mailarchive.py What is the proper setting for PYTHONPATH in this case? Thanks. ----------- Keith

mailman findmember runs very slow
by Wong, Wesley July 14, 2024

July 14, 2024

Hi, I am noticing a performance issue with Mailman 3 when using the "mailman findmember" CLI command to search for email address or name. On average, it takes about 15 - 20 seconds to run a query which is very slow IMHO. When searching through web administrator interface for Users, it takes only 1 -2 seconds. Is there a reason for such a discrepancy between the two interfaces? Is there any tuning to the CLI that could help with the performance issue? Here is the setup information regarding the VM hosting the Mailman 3 server: Memory: 16G CPU Cores: 6 Mailman CORE version: 3.3.9 Python version: 3.11.5 Database: MariaDB 10.6.15 OS: SLES 15 SP5 Thanks. wesley * * * Wesley Wong Senior Systems Engineer (ACIS) (310) 206-2571 wesley.wong(a)anderson.ucla.edu<mailto:wesley.wong@anderson.ucla.edu> UCLA Anderson School of Management | Transformative Leaders

repeated headers in mails from mailinglists
by Tobias Diekershoff July 14, 2024

July 14, 2024

Dear all, we have recently migrated from Mailman2 to Mailman3 and now discovered that all mails going through Mailman3 have the headers Archived-At and List-Archive repeated identically in the mail header ~100 times each. We are running Mailman3 on Debian Bookworm from the Debian repositories (mailman3 3.3.8-2~deb12u2) with postfix (3.7.11-0+deb12u1) and hyperkitty (1.2.1-1). Can somebody of you help me to get rid of the repeated header? Thanks in advance for you help!

Hiding the "subscribe without creating an account"
by Ben Sturmfels July 14, 2024

July 14, 2024

Hi Folks, My Mailman3 installation is receiving a trickle of fake registrations, for which it then attempts to send a "Your confirmation is needed to join..." email, which typically bounce. I suspect these are coming from the "subscribe without creating an account" form on the list summary page. I notice that lists.mailman3.org doesn't show this form at all - you have to create an account to subscribe: https://lists.mailman3.org/mailman3/lists/mailman-users.mailman3.org/ compared to mine with: https://lists.softwarefreedom.com.au/postorius/lists/free-software-melb.lis… Is there a configuration option that does this, or was it a custom change made in the templates? Was the change made to reduce fake registrations? Did it work? Regards, Ben -- Ben Sturmfels Sturm Software Engineering www.sturm.com.au +61 3 9024 2467

Pkl files with ".last" extension
by Keith Christian July 12, 2024

July 12, 2024

In the MM2 to MM3 migration project I'm involved with, I see files with names like config.pkl.last along with config.pkl. Is there a special reason for the ".last" extension and if so, what is it? Thanks, -------- Keith

bulk deletion of messages from Hyperkitty
by Danil Smirnov July 12, 2024

July 12, 2024

Hi, community! After importing from Mailman 2, thousands of badly compiled messages from the past appeared with empty content on the same date (date of import). Is there a safe way to delete them all? If we delete them from the database - hyperkitty_email table - do we need to do some clean-up of hyperkitty_thread table as well? Any advice? BR, Danil Smirnov
