As a temporary workaround, I've limited memory on the mailman-django-uwsgi container to 4 GiB (though, since I just did that this morning, I won't know until after midnight (presumably) if it worked or not), and set the RestartPolicy to always.

I don't know how qcluster is configured in the Debian packages (which are out of date and possibly buggy anyway). You may be using django-q <https://django-q.readthedocs.io/en/latest/> and if so, you should migrate to django-q2 <https://django-q2.readthedocs.io/en/master/>. Both typically use memcached as a backend. Settings that control this are typically ``` # Set retry > timeout. Q_CLUSTER = { 'timeout': 300, 'retry': 360, 'save_limit': 100, 'orm': 'default', } ``` and possibly a setting like `'workers': 2,` (default is the CPU count of the system but see <https://django-q2.readthedocs.io/en/master/configure.html#f1>). ``` CACHES = { 'default': { 'BACKEND': 'django.core.cache.backends.memcached.PyLibMCCache', 'LOCATION': '127.0.0.1:11211', } } ``` although the default if not set is ``` CACHES = { "default": { "BACKEND": "django.core.cache.backends.locmem.LocMemCache", } } ``` It is the `'orm': 'default'` setting that says to use Django's CACHES. See <https://django-q2.readthedocs.io/en/master/brokers.html#django-orm>. You can get info about what qcluster is doing with `manage.py qinfo` and monitor things with `manage.py qmemory` and `manage.py qmonitor`. -- Mark Sapiro <mark(a)msapiro.net> The highway is for gamblers, San Francisco Bay Area, California better use your sense - B.

I think I'm missing how I can configure Mailman so that the actual user's address is used. I think you are missing the point. This is a pseudo DSN. If it were a real DSN it would be something like From: mailer-daemon@somewhere To: listname-bounces@listdomain However, there is no real DSN because Mailman has gotten a reject in it's attempt to deliver to the outgoing MTA so it creates it's own pseudo DSN for the failure. Another way of looking at this is if you configured Mailman to deliver to a local MTA and configured that MTA to relay to your remote MTA, your local MTA would accept the message and then receive the 5xx status upon delivery to the Remote MTA and would then send an appropriate DSN back to the list-bounces address. Since you are skipping the local MTA part, Mailman gets the 5xx status upon delivery to the remote MTA and creates it's own DSN for itself. -- Mark Sapiro <mark(a)msapiro.net> The highway is for gamblers, San Francisco Bay Area, California better use your sense - B.

This is all from one post. The first is normal it just says that Mailman's var/public_suffix_list.dat doesn't exist, but it should be retrieved from https://publicsuffix.org/list/public_suffix_list.dat and then saved at var/public_suffix_list.dat so it doesn't need to be retrieved from the web again until the saved copy is older that the configured dmarc.cache_lifetime (default = 7 days, so that message) after which time the message will be 'Cached copy of public suffix list is out of date' The second is acceptance of the post. The third is a failure in archiving the message. Th HTML should contain an error message with a traceback which should help determine the problem. > Is there a way to kick it into re-running whatever it does at midnight > so I can test this again after putting the public suffix list back?

Midnight is a coincidence in this case. the above are all due to the post with Message-ID: <7500f0e2-1ae1-309d-60d7-6e592c7abf7a(a)west.net> The cached var/public_suffix_list.dat should now be there with a timestamp of Jul 02 00:13:04 (7 days from Jun 25 00:13:04) > Is the last (third) log line excerpt simply a result of the first, or do > I have something else messed up?

That file was for a test only. The German message catalog is at mailman/messages/de/LC_MESSAGES/. That directory should contain a mailman.po and a mailman.mo. If there is no mailman.mo, it needs to be created. The source distribution contains a generate_mo.sh script to generate these for all languages, but you can do the German one by changing to the mailman/messages/de/LC_MESSAGES/ directory in the running installation and doing msgfmt mailman.po -o mailman.mo >> Please be more specific than `all types of system mails`.

If you don't have the mailman/messages/de/LC_MESSAGES/mailman.mo file, this could be the reason, but there may be a bug. -- Mark Sapiro <mark(a)msapiro.net> The highway is for gamblers, San Francisco Bay Area, California better use your sense - B.
