I have tried it using the fqdn url as well as the localhost:8000 url but in both cases requests.get immediately returns the response. The server side pushes the response within milliseconds. But that made me looking another time at the localhost tcpdump: I have noticed two connections to localhost:8000 where gunicorn with mailman_web.wsgi:application is running. The first one is POST /mailman3/lists/community.lists.example.com/anonymous_subscribe the second one is GET /mailman3/api/templates/list/community.lists.example.com/list:user:action:subscribe Both take 5 seconds. First the first one responds then shortly after the second one. I have noticed that only two gunicorn processes are running which looked like only one is a worker. Thus I have added workers=9 (2xncore+1) to /etc/mailman3/gunicorn.conf and restarted mailmanweb.service. Now it's working. So it must have been some kind of deadlock situation because it only had a single worker running. I have just followed the docs from https://docs.mailman3.org/en/latest/install/virtualenv.html#setting-up-guni… which doesn't mention anything about workers and I seriously don't have a clue about gunicorn. Maybe that could be added to the docs? Thanks for the help! Cheers, Gerald

[...] Clearly a total misreading on my part of the Django documentation to which you referred earlier. It talks about having to feed Django multiple settings.py files with different SITE_ID values and running migrate to configure them, then links to the document on migrations which starts out explaining how to use makemigrations to create them. I took that to mean creating and configuring Django sites from the command line required supplying customized database migrations. The particularly misleading bits are where it says: "To set the correct name and domain for your project, you can use a data migration." "In order to serve different sites in production, you’d create a separate settings file with each SITE_ID" It doesn't seem to talk about using django_admin at all (or if it does, it's not mentioned by name, maybe assuming the reader knows to use it in order to perform the necessary steps). Thanks for the clear examples! If these are available somewhere in Django's documentation, I did a terrible job of searching for them. > you need to create a domain in Postorius.

[...] Much appreciated, this was the other bit that was non-obvious to me. I guess you're saying Postorius's view of domains is independent from what's in Mailman Core, and there's no documented CLI/API for manipulating that in Postorius so I'll need to write one based on a reverse-engineering of its source code? Sounds doable now that I know where to look. Thanks again! -- Jeremy Stanley

I'm pretty sure it will install dependencies. I think (everything I say below is based on reading the README.md from pipx's pypa.io repo, so caveat installer) that the complexity that will arise is that (for example) a naive approach like $ pipx install mailman $ pipx install mailmanweb $ pipx install postorius $ pipx install hyperkitty will create 4 separate venvs with 3 copies of mailmanclient, 3 copies of django-mailman3, and two copies of Django. Besides the space waste, there's also the small problem that mailmanweb won't have copies of postorius and hyperkitty in its venv. :-þ pipx has an "inject" command that allows adding other packages to a venv, but I think this means that pipx has no great advantage over the standard way of installing mailman into a venv. pipx also installs stuff into the user's $HOME, specifically into ~/.local/share/pipx/venvs which I think will be kind of annoying if you need to dig into package resources. (I expect that you will still install configs into /etc/mailman3 and various data into /var/lib/mailman3/var or /opt/mailman3 or whatever without a problem.) This would only be an issue for heavy-duty customizers. This can probably be customized. One of the big advantages pipx touts is "look ma, no sudo". That's not really an advantage for system daemons, though. So bottom line is you can do it, but you'll need to study up on pipx arcana, because Mailman is a bunch of daemon it buys you very little, and the result won't look like any Mailman installation you've seen described on mailman-users or StackExchange.

As our organization chose a free open-source software to provide service, I think it might be the only way that we can get the issue resolved since there is no official support service for a volunteer based project. Most importantly, without your detail explanation it will be really hard for us to further study the issue and file the issue in the bug tracking system. It is a good lesson anyway since it really gives me some solid experiences about running codes with different versions of Python and it is sometimes not so trivial when developing unit tests.
