Is a directory: '…/mailman/templates'
by Stefan Tatschner April 14, 2020

April 14, 2020

hey folks, I am struggling with my mailman server for quite some time now. I am on 3.3 and the out runner cannot sent emails any more. According to this issue [1] I found out--by logging the exception as well--, that mailman has this problem: Mar 31 09:34:51 2020 (71057) ACCEPT: <c1e4aa1be5b61c289c69a66a6d55565333d5a35b.camel(a)rumpelsepp.org> Mar 31 09:34:52 2020 (71079) Cannot connect to SMTP server 127.0.0.1 on port 25: [Errno 21] Is a directory: '/usr/lib/python3.8/site-packages/mailman/templates' What the hell is going on here? ☹︎ any ideas what's wrong? The runner doesn't try to connect to postfix, since it fails with a strange template error. Stefan [1]: https://gitlab.com/mailman/mailman/-/issues/514

Protocol version
by David Krantz April 5, 2020

April 5, 2020

Hi. I have the following displayed when I look at the "System Information" in Postorius: Mailman Core Version GNU Mailman 3.3.0 (La Villa Strangiato) Mailman Core API Version 3.0 Mailman Core Python Version 3.7.6 (default, Dec 19 2019, 23:49:42) [GCC 5.4.0 20160609] What surprises me is the protocol version. I have tried to set the protocol version to 3.1 in mailman core (which should be the latest according to the documentation) and restarting both core and web but that gives no effect. Normally I have not had any protocol version defined. Everything seems to work just fine but something is strange, either the documentation, my setup or mailman/postorius. // David

Postorius confirmation mails shown in uwsgi-error.log but not sent
by Ralph Seichter April 4, 2020

April 4, 2020

I have struggled for hours but cannot seem to figure it out. After registering new user accounts in Postorius, the "confirm your address" emails don't get sent via SMTP (my MTA does not even log connection attempts), but their content is displayed in uwsgi-error.log. I think I disabled developer mode in Core and Postorius: $ mailman conf | grep devmode [devmode] enabled: no [devmode] recipient: [devmode] testing: no [devmode] wait: 60s $ grep ^DEBUG settings.py DEBUG = False Users can subscribe via list-join(a)domain.tld, including confirmations. Account registration using the WebUI works as well, it's just the emails that don't get sent. What am I missing, I wonder? -Ralph

Finding a mailman3 installation description that works
by ralf.wiegand＠tena-sda.org April 1, 2020

April 1, 2020

WE are currently using mailman2. I have the task to setup and install a maiman3 server. Postfix is installed and working. Can anybody point me to a link where the actual installation is described using RHEL 7 or RHEL 8. This will be a hardened DISA compliant server, so I am trying to avoid installing compilers and tools that are not part of the standard RHEL 7 repos. Thank You, Best regards, Ralf Wiegand

Mailman3 moving to new server, not able to establish SMTP connection
by Andrew Hodgson March 28, 2020

March 28, 2020

Hi, Whilst we are all stuck in doors I have started a project to move Mailman3 from a Docker installation to a new server using a Python venv. Old server was Debian Jessie and the new one is Buster. Using Exim with stock config. Everything seems to be going ok but mail isn't delivering (cannot connect to SMTP server). I have /opt/mailman which I did chown -R list:list mailman.cfg has following MTA settings: [mta] incoming: mailman.mta.exim4.LMTP configuration: python:mailman.config.exim4 I wrote a Systemd unit which starts Mailman from the venv and started up Mailman once I got Postgres sorted so it would create the necessary files in the var directory structure. One thing I noticed and had to fix is that it doesn't creat the directories for existing lists, and the Exim config examples out there check for the existance of those directories to identify whether the address exists. I created those anyway and set ownership perms as before. Once I fixed that I sent a test message to the owner address and that routed correctly and the headers indicated the message was sent back to localhost by Mailman. However I can't get it to route a list message, here is a log showing the start of the Mailman master processes and me sending a test message from Outlook (so incoming mail is routing ok): Mar 28 16:03:20 2020 (21877) Master started Mar 28 16:03:32 2020 (21889) lmtp runner started.

This is a dualstack machine and I was wondering whether we had any IPV6 issues (I had an issue with Gunicorn and Nginx routing traffic due to this earlier that I had to sort), but as owner addresses are working I don't know what is different on that. Any suggestions? Thanks. Andrew.

421 - Too many sessions from source IP
by hansen＠rc.org March 27, 2020

March 27, 2020

My new MM3 server is receiving these errors from cox.net: "(delivery temporarily suspended: host cxr.mx.a.cloudfilter.net[34.212.80.54] refused to talk to me: 421 cxr-ibgw-6004a.stratus.cloudmark.com cmsmtp too many sessions from 213.125.4.246. Refer to Error Codes section at https://www.cox.com/residential/support/email-error-codes.html for more information. AUP#CXCNCT) " The link gives just this: 421 - [too many sessions from <source IP>] The sending IP address has exceeded the five maximum concurrent connection limit. Configure your sending server to establish no more than five concurrent connections. 1. Is that a legitimate excuse to refuse passing on emails or is cox.net too stingy? 2. Is that a setting we need to change in Mailman somewhere? Or should this be handled in some Postfix setting? Yours, Allan

Things I miss about mailman2
by Quanah Gibson-Mount March 24, 2020

March 24, 2020

Now that we are on mailman3, I'm finding things that were really useful in mailman2 are completely missing in mailman3, which seems odd, since they in particular affect the ability of list moderators to do their job well. a) When a post was made to a moderated list in mailman2, I would get an email that included a LINK to the held email. Now I just get a canned email saying I need to go to the dashboard, blah blah. Why was this link removed? It was extremely useful and now I have to jump through extra hoops. b) When a post is made to a moderated list in mailman2, when I went to the page to approve/deny/discard, there was additionally an option to remove the moderated flag from the user for all future emails. This option no longer exists. This was EXTREMELY useful, as we force all new members of the list to be moderated for a time while we evaluate the quality of their postings. Now I have to go manually track down the user and their settings. Unnecessary extra hoops to jump through c) When a post is made to a moderated list, one of the options when selecting REJECT was it allowed me to set a custom message when rejecting the email. This was extremely useful. For example today, someone emailed our bug tracking list directly instead of filing a bug. In the past, I would have added a note to them about what they should do (in this case, I would have told them to send their email to our community technical discussion list). Now I can no longer do that, I can only reject it or discard it. Why was this removed? --Quanah -- Quanah Gibson-Mount Product Architect Symas Corporation Packaged, certified, and supported LDAP solutions powered by OpenLDAP: <http://www.symas.com>

Xapian alternatives
by Andrew Bernard March 24, 2020

March 24, 2020

Are there alternative search engines to Xapian that can be used for Mailman 3? I have come to understand that Xapian development stalled in the v2.0 attempt.

March 19, 2020

Now I am seeing this in the log every few seconds: 12:12:29 [Q] INFO Process-1:4 processing [rebuild_thread_cache_votes] 12:12:29 [Q] ERROR Failed [rebuild_thread_cache_votes] - Thread matching query does not exist. : Traceback (most recent call last): File "/opt/mailman/mm/venv/lib/python3.7/site-packages/django_q-1.0.1-py3.7.egg/django_q/cluster.py", line 377, in worker res = f(*task['args'], **task['kwargs']) File "/opt/mailman/mm/venv/lib/python3.7/site-packages/HyperKitty-1.2.3-py3.7.egg/hyperkitty/tasks.py", line 189, in _rebuild_thread_cache_votes thread = Thread.objects.get(id=thread_id) File "/opt/mailman/mm/venv/lib/python3.7/site-packages/Django-2.1.9-py3.7.egg/django/db/models/manager.py", line 82, in manager_method return getattr(self.get_queryset(), name)(*args, **kwargs) File "/opt/mailman/mm/venv/lib/python3.7/site-packages/Django-2.1.9-py3.7.egg/django/db/models/query.py", line 399, in get self.model._meta.object_name hyperkitty.models.thread.Thread.DoesNotExist: Thread matching query does not exist.

I am having a lot of trouble with these sort of errors, as you will see from my flurry of posts recently. Yes, I am running all the jobs. Andrew
