Postorius fails to show list because of a large message being held
by Gilles Filippini 22 Dec '21

22 Dec '21

Hi, Recently a member of one of our private lists sent a message with a picture attached. Because of the large message size (23MB) it was put into the moderation queue. But since then postorius fails to open the list's page with this error: Something went wrong Mailman REST API not available. Please start Mailman core. The database logs show that it processed a request related to the held message just before failing: LOG: statement: SELECT message.id AS message_id_1, message.message_id AS message_message_id, message.message_id_hash AS message_message_id_hash, message.path AS message_path FROM message WHERE message.message_id = '<CAEcCghAdp+20jiG19jNGX06xhJ-iYvZGyyV8b-toW7LqCSv5JQ(a)mail.gmail.com>' LIMIT 1 Mailman Core logs: [2020-07-14 10:41:21 +0000] [36] [CRITICAL] WORKER TIMEOUT (pid:49) [2020-07-14 10:41:21 +0000] [49] [INFO] Worker exiting (pid: 49) [2020-07-14 10:41:22 +0000] [50] [INFO] Booting worker with pid: 50 How should I proceed to unblock the situation? Thanks, _g.

Negative number for digest size
by Gila Halpern 19 Nov '21

If I set the digest size threshold to -1, will that make the digest size unlimited, and it will send once per period specified in the digest frequency setting?

Moderation Action Changed After Import
by Brian Carpenter 12 Nov '21

12 Nov '21

I migrated a Mailman 2 list using import21 and the list's config.pck into a Mailman 3 list. The list owner reported back that about 98% of the list members had their moderation setting changed to Reject (with notification). He said the previous moderation was the list's default which was hold for moderation. Is such a thing possible with an import job? Is this perhaps a bug that has been reported previously? -- Brian Carpenter Harmonylists.com Emwd.com

mm3mod: command line moderation tool
by David Bremner 18 Sep '21

18 Sep '21

Because we're not running postorius, and the moderate-by-mail change is not available in the older version of mailman3 we're running, I needed a tool to moderate lists from the command line. I found mailman-tools, but wasn't able to get them working with python3, so I started from scratch. Maybe someone else will find it useful https://git.tethera.net/mm3mod.git/about/ It's a work in progress, but I am running the version from that repo in production. Like any program using the REST interface, in principle this has complete administrator access to your mailman site, so you need to to trust both this code and the users you let run it. I do run it in "kiosk mode" via ssh command="/home/listmod/.local/bin/mm3mod" ssh-rsa blahblah in .ssh/authorized_keys. This is more of a keeping-honest-people-honest kind of thing.

New messages not being archived
by Sarah H 07 Sep '21

07 Sep '21

I have 2 active lists that are properly mailing out and working, plus an admin testing list that is as well. The list info pane correctly shows the mail volume and the imported archives from the previous 2.1 installation are present for both active lists. None of the 3 lists are generating new entries in the archive, all 3 are set up with default settings except 1 active and admin are set to private. I know that hyperkitty is showing some new content as admin was created in postorius and the list is present in hyperkitty and working in mailman. None of the logs show anything of note, mailmanweb.log has no new entries since it caused a serious issue when I changed the domain, uwsgi-error is the same and uwsgi.log has proper access logs. When trying to add a new thread via the hyperkitty interface I can see the email go through the maillog, I get the email with the entered content and everything else works, it just doesn't add a new thread to the archive. The installation is set up with the default settings from the virtualenv installation guide. Any assistance would be appreciated.

How to increase maximum size of the message in mailman
by Shashikanth Komandoor 31 Aug '21

31 Aug '21

Hi Team, I am currently running Mailman 3 with version 3.3.1 and in-built postfix version 2.10.1-6 on RHEL 7.5 with PostgreSQL 11.7 version with default values. I am almost running 2200 lists with 128 GB RAM and 24 Cores on a single VM and on which all the mailman 3 components are running. I have been running this setup in production for the past 2 years and 6 months. I have recently encountered a scenario where a user sent mail with a PPT attachment to one of the lists on the said mailman server. The mail is received by postfix on the mailman server and is handed over to mailman at *0.0.0.0:8024 <http://0.0.0.0:8024>.* But the /var/log/maillog says the below error during the above hand shake. *status=bounced (host 0.0.0.0[0.0.0.0] said: 552 Error: Too much mail data* I have browsed google for understanding and fixing the issue. During which I encountered the information given by Mr. Mark Sapio at https://lists.mailman3.org/archives/list/mailman-users@mailman3.org/thread/…. But I could not fix the issue as it is mentioned the default size limit is 33554432. I request someone to suggest where I can customize the value 33554432 and put a higher value or can be configured without any limit. I have configured message_size_limit as 100MB at postfix level. I would like to configure, in fact, the same at mailman level too. But I don't understand where to edit. I tried editing the variable DATA_SIZE_DEFAULT value in /var/lib/mailman/mailman/.tox/py36-nocov/lib/python3.6/site-packages/aiosmtpd/smtp.py file but unfortunately no luck. So, could someone please help us in this regard ? Also, please also let me know if there is any limitation specific for the attachments so that I can customize that too respectively. -- Thanks & Regards, Shashi Kanth.K 9052671936

Question about message bounce stats
by Ruth Ivimey-Cook 30 Aug '21

30 Aug '21

When I used Mailgun some time back, it had a feature of, for any specific outgoing mailing, being able to show you stats and other details of which mails were received ok, which bounced, and which were undeliverable, which I found helpful to check every so often. Their system also kept track of long-term trends, eg for addresses that frequently failed. Does Mailman3 keep such stats, and if so is there any way to get access to them, even if only API? I would think it useful to do so (and yes, for individual outgoing messages at least for a period).

auto-away notices as bounces
by Andreas Barth 30 Aug '21

30 Aug '21

Hi, I had a user complaint that his subscription was disabled. Looking into details, his mail provider sent out lots of auto aways notices marked with Auto-Submitted: auto-replied (vacation) Should we not exclude these as being counted as bounce? (List settings are "Individual" for "Personalize" and yes for both "Include RFC2369 headers" and "Include the list post header". Regards, Andi

(nagios-)Monitoring for mailman3?
by Andreas Barth 29 Aug '21

29 Aug '21

Hi together, does anyone have a sensible nagios monitoring for mailman3? (I had the issue that after a data base restart mailman3 was somehow disturbed but the basic web interface was still available, just the detailed pages like .../lists/$listid/ showed the error) Andi
