New messages not being archived

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 Aug. 31, 2021

Aug. 31, 2021

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 Aug. 30, 2021

Aug. 30, 2021

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 Aug. 30, 2021

Aug. 30, 2021

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 Aug. 29, 2021

Aug. 29, 2021

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

Logging subscriptions and unsubscriptions
by Christian Schoepplein Aug. 28, 2021

Aug. 28, 2021

Hi, I am in the process to migrate from mailman 2 to mailman 3 and currently I am setting up the new environment and do some tests and play around with the new system. I'd like to have a seperate log for list subscriptions and unsubscriptions. For that reason I added the following section to the mailman-extra.cfg file: [logging.subscribe] path: subscribe.log That created a file called subscribe.log but not everything regarding subscription / unsubscriptions is added to the file. When subscribing and unsubscribing a user via mail only the following line is shown: Aug 27 10:58:31 2021 (28) tmod(a)mm3.example.com: held subscription request from chris(a)example.com Nothing regarding the finished subscription and absolutely nothing regarding the unsubscription performed later. Also in mailman.log I can find the following lines: Aug 27 10:58:05 2021 (28) deque: do_confirm_verify Traceback (most recent call last): File "/usr/lib/python3.8/site-packages/mailman/app/workflow.py", line 69, in __next__ return step() File "/usr/lib/python3.8/site-packages/mailman/app/subscriptions.py", line 356, in _step_send_confirmation raise StopIteration StopIteration Aug 27 10:58:31 2021 (28) deque: subscribe_from_restored Traceback (most recent call last): File "/usr/lib/python3.8/site-packages/mailman/app/workflow.py", line 69, in __next__ return step() File "/usr/lib/python3.8/site-packages/mailman/app/subscriptions.py", line 326, in _step_get_moderator_approval raise StopIteration StopIteration Aug 27 10:58:33 2021 (29) OWNER: <163005471133.28.13827351997075408419@mailman-core> Is this because a higher logging level or is this an error? I can find nothing really helpfull regarding subscriptions and unsubscriptions in any logfile. Is this wanted or can this changed by any configuration setting or are this information stored in the database? Cheers, Schoepp

Unwanted E-mail to Maillists Submitted via Postorius Interface
by matthew＠alberti.us Aug. 28, 2021

Aug. 28, 2021

Hi Everyone, I’ve seen a recent uptick in SPAM messages making it into mailing lists. Looking at the raw, it seems that the e-mails are being submitted thru the Postorius/Hyperkitty “Start a New Thread” interface. Is there a way to turn that off? We would want people to only be able to post via e-mail. Part of the problem is that our anti-spam system RSPAMD trusts the mailman-web IP… so it doesn’t scan things originating from there.. ☹ Another uestion: Is there a way to implement captcha, or is there a recommended gate that can be put in the signup process? Apparently bots are finding a way thru the signup process, and then sending messages to the list via the Postorius web interface. There seems to be a Django plugin for it; but it appears the Mailman code would have to be adjusted to implement it. I’m open to any suggestions, including on places to check for misconfiguration. 😊 Thanks. - Matt Alberti

Error on timeout vs retry values
by Robert Moody Aug. 25, 2021

Aug. 25, 2021

Hi everyone, I have recently setup a new mailman3 service using the venv method. Everything is functionally working however I keep getting an error sent to the mailman email every min which I can not seem to figure out why. /opt/mailman/venv/lib/python3.7/site-packages/django_q/conf.py:142: UserWarning: Retry and timeout are misconfigured. Set retry larger than timeout, failure to do so will cause the tasks to be retriggered before completion. See https://django-q.readthedocs.io/en/latest/configure.html#retry for details. See https://django-q.readthedocs.io/en/latest/configure.html#retry for details.""" I have edited the timeout and retry values in the /opt/mailman/venv/lib/python3.7/site-packages/django_q/conf.py file and restarted both mailman and mailman-web however this still keeps repeating. Any ideas? Regards, Robert -- This message has been scanned for viruses and dangerous content by MailScanner, and is believed to be clean.
