Timeout in Postorius when trying to approve or reject moderated messages
by Sebastian Hagedorn Aug. 30, 2020

Aug. 30, 2020

Hi, I just set up a new Mailman 3 Suite installation (GNU Mailman 3.3.1 (Tom Sawyer)) on CentOS 7 using the virtualenv installation guide: https://docs.mailman3.org/en/latest/install/virtualenv.html I encountered a few issues, but I was able to resolve all of them, I think. All three components of the suite are up and running. The backend is a MariaDB database, the frontend is Apache with mod_wsgi. I can send messages to the server, and they are delivered to list members. One thing that I can't figure out is why I can't approve or reject messages that are held for moderation. In case it matters, I'm trying to moderate the list using the "root" account. Discarding works, but when I try to either accept or reject a message, there is a timeout. I can't find anything in mailman.log, mailmansuite.log or even /var/log/httpd/access_log. I managed to reject and approve messages manually using mailmanclient and the REST API, so the issue appears to be somewhere between Postorius 1.3.3 and mailmancore.

Throttle outgoing emails to a certain rate?
by arvid.teichtmann＠gmx.de Aug. 21, 2020

Aug. 21, 2020

Is there a possibility to throttle the sending of outgoing emails to a certain rate, e.g. 100 emails per hour, or to split them up into corresponding chunks? I run Mailman 2.1.33 on a hosted server and the provider only allows me to send a maximum of 100 emails per hour. The excess emails are also simply discarded and the sender and list administrator get a bunch of error emails. This is very annoying, especially because I didn't know about it and the problem only now occurs occasionally during operation... ;-( Thanks for all hints.

Spam sign ups
by Seth Seeger Aug. 21, 2020

Aug. 21, 2020

Hello all, I've suddenly started getting a slow but steady stream of fake sign ups. They fail because I'm getting a bounce back from the mail host saying that the email address they signed up with doesn't exist. I know this was asked a while back on this list, but I'm hoping there might be an update? Any way to add an am-I-human test to the sign up? Thanks, Seth

Aug. 19, 2020

Hi, it’s been quite a while since I’ve been back to the list, mailman has been working very well for me But recently it has stopped working. I’m not exactly sure what I did to cause this. I’m not seeing any clear error message. Running on Ubuntu linux, I don’t quite remember how to determine my mailman version.

Invalid confirm text
by w.schoener＠alp.dillingen.de Aug. 19, 2020

Aug. 19, 2020

Hi there, I am new to mailman 3, python and django. I try to configure a mailman 3 list. To establish german text, I used the web-admin interface of mm3 in the "templates"-section. I inserted a text for "The message sent to subscribers when a subscription confirmation is required" Now, when I try to subscribe to the list, I get my first message in german language, with the confirm request: return the message unchange. When I return the message, I get an answer: Invalid confirm text. My request is pending. And there is no way to solve this pending request, in the webinterface, no subscription request is shown, no member is shown and no no-member is shown. Have you any hint, what is going wrong. What do I have to respect to create a message, where the confirmation is working. Thank you Wolfgang

Single-Sign-out for List member
by w.schoener＠alp.dillingen.de Aug. 17, 2020

Aug. 17, 2020

Hello, I have to configure mailman 3 for a german company. The privacy policy in our country demands for mailing-lists, that its member can sign out in one step, it is called sigle-sign-out. So I would like to ad a link in the footer of every message, with which every receiver/member can sign out of the newsletter with one click. It does not seam to be possible, to put this into effect with mailman 3. Does anybody have any hints, how to create a link, and when this link is called, the user is signed out of the newsletter. Thank you, Wolfgang

base64 re-encoding and line endings
by David Bremner Aug. 15, 2020

Aug. 15, 2020

I (along with some other admins) run a mailman3 (3.2.1, on debian stable) mailing list for notmuch (https://notmuchmail.org) It's our main method of reviewing, so we get lots of mail from git-send-email. Occasionaly people send it with Content-Transfer-Encoding 8bit. As far as I can tell what happens then is mailman3 re-encodes it as base64, taking the line endings as CRLF. git-am is unable to apply the patches that have been re-encoded. This seems somewhat related to [1]. Like one commentator there, I would be happy to be able to turn off the re-encoding, although I have the feeling from playing with the python email libraries that this might not be that easy. I'm writing in hope that someone can suggest another workaround, perhaps some kind line-ending rewriting before base64 encoding. I guess with 8bit transfer encoding there probably isn't a clear distinction between the line-endings on the wire, and the intended line-endings for delivery, but it could be inferred from the "X-Mailer: git-send-email" header. As a test, I sent the same patch through our mailman instance with Content-Transfer-Encoding base64 and that applies fine, since the original \n line endings are inside the base64 container. It's a known mis-feature of git-am that it can handle either CRLF line endings or base64 encoding, but not the combination of both. I have a local workaround involving re-formatting the patches, but I'd really like anyone to be able to apply the patches from the list archive. [1]: https://gitlab.com/mailman/mailman/-/issues/269

Announce Only List
by joseverde＠gmail.com Aug. 14, 2020

Aug. 14, 2020

So if we want to make a list announce only (e.g. only specific folks) can post, I've found I can set the list settings to automatically discard messages from members and non-members. Then I go into the individual permissions on each user to be allowed to post without moderation. This works fine, however it seems cumbersome. My expected solution was to make the announce only members moderators - however it appears being a moderator does not give any special ability to post to the list (nor does it appear to make you a 'member' from the point of mailman when sending messages to the list, since a moderator who is not a subscriber gets treated like a nonmember from the posting permissions perspective). Is this correct?

I've recently migrated from Mailman 2 to Mailman 3 but I'm setting up Hyperkitty just now.

How to Unshunt Specific Message ?
by Shashikanth Komandoor Aug. 12, 2020

Aug. 12, 2020

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 in production environment from the past 3 months almost. I learnt how to unshunt the messages that got unshunted in mailman 3. But the command *mailman unshunt* would unshunt all the messages in the shunt queue. I want only a specific message to be unshunted and resent. I don't find my requirement reached with the help of *mailman unshunt*. Please suggest. -- Thanks & Regards, Shashi Kanth.K 9052671936 <https://www.avast.com/sig-email?utm_medium=email&utm_source=link&utm_campai…> Virus-free. www.avast.com <https://www.avast.com/sig-email?utm_medium=email&utm_source=link&utm_campai…> <#DAB4FAD8-2DD7-40BB-A1B8-4E2AA1F9FDF2>

How to create user accounts and mail addresses through CURL instead of Site Administration ?
by Shashikanth Komandoor Aug. 11, 2020

Aug. 11, 2020

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 in production environment from the past 3 months almost. I am currently automating a few things using the CURL commands but only postorius related as of now. Now I have a requirement. I need to create a lot many users and their mapping email ids through Site Administration almost daily. But it is becoming to do the same through Graphical Interface. So, I just want to know the CURL commands that can be used to create the user accounts and email ids mapped to user accounts. Please do the needful. -- Thanks & Regards, Shashi Kanth.K 9052671936 <https://www.avast.com/sig-email?utm_medium=email&utm_source=link&utm_campai…> Virus-free. www.avast.com <https://www.avast.com/sig-email?utm_medium=email&utm_source=link&utm_campai…> <#DAB4FAD8-2DD7-40BB-A1B8-4E2AA1F9FDF2>

Better documentation for Mailman Core's config options
by Abhilash Raj Aug. 7, 2020

Aug. 7, 2020

Hey All, For the past few days, I've been trying to improve the documentation style for Mailman Core's config options. Internally, Mailman has all configurations defined in an ini formatted `schema.cfg` file, which serves as a schema for our `zope.configuration` library. We had that file simply embedded in the sphinx documentation previously as a wall of text. I ended up writing a Sphinx (our documentation generator) plugin which parses the config file and presents the same documentation with more bells and whistles so it is easier to lookup and link sections and config options.[1] The process of doing that was fun and I learnt how to write a simple sphinx plugin, so yay! It treats the comments above each config option in the ini file as it's doc and basically generates ReST text that it passes to Sphinx to parse and convert to the markup format that you see in browser. You can look at it in the source repo[2] . Do note that not all sections are documented yet, I am still figuring out what would be a good way to document template sections like `[plugins.master]` and other similar sections of that kind. [1]: https://gnu-mailman--667.org.readthedocs.build/projects/mailman/en/667/src/… ((URL is for the PR, the main doc seems like is serving the cached version from an older build).

Installation Help on Ubuntu 18
by joseverde＠gmail.com Aug. 3, 2020

Aug. 3, 2020

Hi folks, I spent many hours last night trying to get Mailman 3 up and running. I am using Ubuntu on a Digital Ocean LAMP droplet (so PHP, Apache, Sql, and Postfix are already installed). The LAMP stack works as I have a successful installation of YOURLS going on. So, I tried to use this guide (https://docs.google.com/document/d/1xIcSsoNFp2nHi7r4eQys00s9a0k2sHhu1V5Plan…) to install the Mailman3 package and got to the configuration screen (the one with all the DOS-esque GUI). I ran it but it kept saying the DB wasn't installed. Was I supposed to create SQL databases and users before running that and use those usernames/databases in the credentials it asks for? It doesn't seem like that in the way it asks the questions (since it asks to create a password) but I wasn't sure. Anywho, I tried to remove the package completely and restart but I keep spinning my wheels. So my questions: 1. Does that guide actually work? Did I just foul up the database part? 2. Is there a better way to install mailman3 with some nice step-by-step directions to follow? 3. Is there a way to completely wipe my previous installs without wiping the server? ( I didn't back up...silly I know ). I used apt-get --purge remove to uninstall mailman3 and mailman to start over, did that do the trick? Sorry for all the questions.

Custom Templates and reject_message() error
by Marcel Pietschmann Aug. 2, 2020

Aug. 2, 2020

Hi everyone, I'm running Mailman 3 in maxking's Docker container (tag 0.3). Mailman3 runs really well, thanks for that good job! But I noticed two errors. 1) When a new list is created, Mailman will not notify the list owners of their new mailing list. I tested it with the default template "domain:admin:notice:new-list.txt" and my own template (which i copied in $var_dir/templates/domains/DOMAIN/de/ Any customs templates in $var_dir/templates... aren't sent out, always the default templates from /usr/lib/python3/site-packages/mailman/templates/de. I can't find anything in the logs for that issue. 2) When a post requires an approval and I reject it with a notification a server error occurs: "An error occurred while processing your request." The Traceback in mailmanweb.log is: ERROR 2020-08-01 16:19:19,926 17 django.request Internal Server Error: /postorius/lists/list.domain.de/held_messages/moderate Traceback (most recent call last): File "/usr/lib/python3.6/site-packages/django/core/handlers/exception.py", line 34, in inner response = get_response(request) File "/usr/lib/python3.6/site-packages/django/core/handlers/base.py", line 115, in _get_response response = self.process_exception_by_middleware(e, request) File "/usr/lib/python3.6/site-packages/django/core/handlers/base.py", line 113, in _get_response response = wrapped_callback(request, *callback_args, **callback_kwargs) File "/usr/lib/python3.6/site-packages/django/views/decorators/http.py", line 40, in inner return func(request, *args, **kwargs) File "/usr/lib/python3.6/site-packages/django/contrib/auth/decorators.py", line 21, in _wrapped_view return view_func(request, *args, **kwargs) File "/usr/lib/python3.6/site-packages/postorius/auth/decorators.py", line 60, in wrapper return fn(*args, **kwargs) File "/usr/lib/python3.6/site-packages/postorius/views/list.py", line 549, in moderate_held_message mailing_list.reject_message(msg.request_id, reason=reason) TypeError: reject_message() got an unexpected keyword argument 'reason' Thanks a lot for any suggestion.

Owner's or Moderator's Lists
by Johnny Cison July 31, 2020

July 31, 2020

I feel like I'm missing something obvious, but is there a page in Postorius that lists all of the lists of which the user is the owner or moderator? When I visit the /lists/ URL as an admin, I see a full list. When I visit the /lists/ URL without being logged in, I see public lists. I've heard from two people who are list owners (and confirmed they're logged in and their email is showing as verified) that they also just see the public lists on the /lists/ page. (I tried searching the archives and didn't see anything that addressed this. My apologies if I overlooked it!)

Good choice of defaults for content filtering?
by hansen＠rc.org July 31, 2020

July 31, 2020

Hi all, I had MM2 set to the default filtering that I think came OOTB. MM3 has none such and I was wondering: a. What were those MM2 defaults (My MM2 server is long gone now). b. Is there a better set today. I know that MIME types can be faked, but they have worked. I want to avoid anything that can contain malicious code while also allowing simple text to go through.

A little stuck with installation of MM3 - ModuleNotFoundError: No module named 'flufl.lock'

500 Internal Server Error on specific list pages
by Johnny Cison July 30, 2020

July 30, 2020

I have a new Mailman 3 server set up and am having a strange issue with just one particular list.

The email confirming the registration of an account on postorius is not correctly translated in Italian
by Massimo Zappalà July 30, 2020

July 30, 2020

Hi everyone, thanks to the files.po on Weblate, I have translated all Mailman-Core, Postorius, Hyperkitty and Django_mailman3. I have also translated the confirmation message to subscribe to a list. Everything works, except for this: When I register a new account on postorius, he sends me a confirmation email totally in English, except the following final block which is sent in Italian: in my /usr/lib/python3/dist-packages/allauth/locale/it/LC_MESSAGES/django.po #: templates/account/email/email_confirmation_message.txt:7 #, python-format msgid "" "Thank you from %(site_name)s!\n" "%(site_domain)s" msgstr "" "Grazie da %(site_name)s!\n" "%(site_domain)s" By carefully analyzing the same file .po, I notice that the Italian translation of the whole text already exists. Why does the confirmation email arrive in English? #: templates/account/email/email_confirmation_message.txt:1 #, fuzzy, python-format #| msgid "" #| "User %(user_display)s at %(site_name)s has given this as an email " #| "address.\n" #| "\n" #| "To confirm this is correct, go to %(activate_url)s\n" msgid "" "Hello from %(site_name)s!\n" "\n" "You're receiving this e-mail because user %(user_display)s has given yours " "as an e-mail address to connect their account.\n" "\n" "To confirm this is correct, go to %(activate_url)s\n" msgstr "" "Ciao da %(site_name)s!\n" "\n" "L'Utente %(user_display)s di %(site_name)s ha registrato questo indirizzo e-" "mail.\n" "Per confermare, clicca qui %(activate_url)s\n" Thanks Max

Hi everyone, My Version installed on Debian buster: mailman3: 3.2.1 postorius: 1.2.4 hyperkitty: 1.2.2 All interfaces work well in Italian language, but "Welcome message" is in English.

mailman2 import not working
by Abhijith PA July 29, 2020

July 29, 2020

Hello. Recently I migrated a mailman2 mailing list to mailmam3. There was one problem[1] I faced. Currently I am running Debian packaged version (3.2.2-1) which don't have this fix. But it was manually done with this[2] method. Basically this is what I did for migration: ------------------------------------------- mailman create -o <foo(a)example.com> foo-bar(a)lists.example.com mailman import 21 foo-bar(a)lists.example.com path/to/config.pck ------------------------------------------- Then imported archives with ------------------------------------------ python3 manage.py hyperkitty_import --pythonpath /usr/share/mailman3-web --settings settings -l foo-list(a)list.example.com <path to>/foo-list.mbox python3 manage.py update_index_one_list foo-list(a)example.com --pythonpath /usr/share/mailman3-web --settings settings ------------------------------------------ After everything done tried a test mail, but didn't reach any of the inbox though mail is archived. mailman.log says message is accepted ACCEPT: <FEE2E515-C054-41E6-9853-744D3312A137(a)xxxxxx.org> Nothing after this.

Could not locate column in row for column 'user.id'
by Shashikanth Komandoor July 28, 2020

July 28, 2020

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 in production environment from the past 2 months almost. From the past few days, I found my server is responding to the users very slowly and throwing the Server Error page (of course getting the required page after multiple refreshes) for almost every click on the postorius pages (not yet observed on hyperkitty front end which in fact is not so important for me as of now). During that time, I observed in the mailman.log an error message saying "Could not locate column in row for column 'user.id'". The complete traceback log is attached with the mail. The error message is generated for almost all the lists and all the clicks. And despite this error message, I don't know how the required page is loaded after a few refreshes of the webpage. I don't know how to resolve this issue. Please advise. Also, please let me know if anything I need to share with you. -- Thanks & Regards, Shashi Kanth.K 9052671936

# comment allowed in a template file?
by skenny＠scss.tcd.ie July 28, 2020

July 28, 2020

I've found that dropping files in to the templates directory is a simple and convenient way to make certain things happen. E.g. I can set a default footer for all posts by putting the desired content in a file called var/templates/site/en/list:member:generic:footer.txt. I'm running Mailman 3 in maxking's Docker container. I'm also using Puppet to do as much configuration as possible, so I'd like to add a comment to the file that reads something like: # This file is managed by Puppet. Is it ok to do this? I may not have searched the docs enough, but I couldn't find anything relating to comments. One other observation in case it's any use: Initially, I created the template files with owner set to "root". This resulted in postings to lists getting stuck in mailman-core. It's vital that these files are owned by user "mailman". Once I changed the owner of the file to the latter, everything worked. Stephen

Hi Team, Today, I found an error message like "Multiple rows were found for one_or_none()" when a hold message is approved for a list. Until yesterday the mails were accepted and delivered fine. But today the above said error message is thrown. Apart from that, I saw the mail had gone into the shunt queue. The "mailman qfile" output of the shunt message and the respective traceback log from mailman.log are attached. You may please go through them and help me out. Please also let me know if I have to share any more details. -- Thanks & Regards, Shashi Kanth.K 9052671936

mailman3 nightly script(s) are leaking memory + mitigation
by Mark Dadgar July 24, 2020

July 24, 2020

So as I mentioned in another thread, I have a shiny new install of mailman3 latest using venv (thanks, Brian!). It’s running on ubuntu 20.04 using python 3.8.2, django 2.2.12, nginx, postgres, and memcached. The only functions this server runs are 1) postfix and dovecot for a small number of personal email accounts, and 2) mailman3 for a couple of mailing lists (one of which is fairly high traffic). Not long after install, I saw a couple of instances of the OOM killer activating in the logs.

I am still seeing the erosion of a couple of MB of swap each day, but it’s WAY better than losing 250MB-350MB overnight.

Re: Mailman REST API not available. Please start Mailman Core.
by Shashikanth Komandoor July 23, 2020

July 23, 2020

Thank you Mark for your response. I understood that gunicorn is a front end that is used like web server like nginx. But I don't think I am using it instead I am using the httpd to redirect requests to postorius. And I am starting the mailman-suite with the command "python manage.py runserver 0.0.0.0:8000 --insecure &". Hope this does not use gunicorn (which of course I don't know what it is until now). Please correct me if any point I am mentioning is wrong. So, in this case, do you think configuring gunicorn as below would work: *calling gunicorn.cfg in mailman.cfg as below * *[webservice]* *configuration: /var/lib/mailman/mailman/src/mailman/config/gunicorn.cfg* *and content of gunicorn.cfg as below* *(venv3) [root@lsmgr mailman]# cat /var/lib/mailman/mailman/src/mailman/config/gunicorn.cfg[gunicorn]# All the options that can be put here are available at# http://docs.gunicorn.org/en/stable/settings.html#settings <http://docs.gunicorn.org/en/stable/settings.html#settings># No of seconds to wait before killing the worker processes.* *workers = 4graceful_timeout = 90* Also what is the difference between timeout and graceful_timeout ?

Re: [ERROR] Error handling request List archivers

July 23, 2020

Thank you Mark for guiding me to the benefit of putting the list and so I have added the list. Along with the [archiver.hyperkitty], [mta] and [database], few lines of my mailman.cfg look like below: *[webservice]workers = 4timeout = 900* The above block of webservice is added yesterday for testing or trail as I am getting the above issue. And there is no line that is calling *gunicorn* in my mailman.cfg. Apart from that I tried to locate and see the content of the gunicorn.cfg file as below : *(venv3) [root@lsmgr mailman]# cat /var/lib/mailman/mailman/src/mailman/config/gunicorn.cfg[gunicorn]# All the options that can be put here are available at# http://docs.gunicorn.org/en/stable/settings.html#settings <http://docs.gunicorn.org/en/stable/settings.html#settings># No of seconds to wait before killing the worker processes.graceful_timeout = 30* Please confirm the time I have to change is *graceful_timeout *in *gunicorn.cfg* and if I have changed how do I restart the *gunicorn*.

migration plan and auto responder
by Mohsen Masoudfar July 23, 2020

July 23, 2020

Hi, I am writing this in the hope to get some good advises for migration lists from Mailman2 to Mailman3. Thanks a lot in advance. Here is the requirements: * During the migration the old system shouldn't process the emails for the list under migration in the normal way. It should send an email, and only one to the member who sent the original email to the list saying the list is under migration. I know I could do this by auto responder, but the original email would be processed and sent to all members, which I want to block . * After migration the old system should send, per auto responder again, an email to the member who sent to the list, mentioning the new address (the domain is a new one, the list name the same), but again not sending the original email to the list members. * No hackers, robots, spammers should get the new list address. The lists are all hidden. Best regards Mohsen Masoudfar Lead System Analyst, IT Operation American Association for the Advancement of Science 1200 New York Ave, NW, Washington, DC 20005 202-326-7087

Python 3.5 support?
by Joel Lord July 22, 2020

July 22, 2020

I'm looking through the recent changes to Core and Postorius and I keep spotting what looks like removal of the test cases for Python 3.5. Is the next release going to be dropping support for 3.5? Is this because 3.5 is going EOL shortly or because there are changes in the upcoming release that actively will not work on 3.5? -- Joel Lord

Docker Support Sucks
by Brian Carpenter July 22, 2020

July 22, 2020

Ok, now that I got that out of the way. Maybe I can get some help here for a Docker Installation of Mailman 3. I updated a Maxking's Docker installation to Postorius 1.3.3. It made my client's list unusable to a continual stream of removals due to ghost bounce processes. So, I want to totally move away from the use of Docker (mainly because I have found it buggy and the support is simply lacking) and install Mailman 3 for this client from source. However I need to get an export of their list members. But of course, I can't. Rest API times out and I don't know how to apply the instructions I was given to fix it and I don't have days to way for one. So please help. I increased the gunicorn workers to 4, hoping that would allow me to do the CSV export. No. So was given these instructions: ### The issues seems to be due to timeout not due to high load. You want to increase the timeout for gunicorn and you can do that by specifying a gunicorn.ini config file: [webservice] configuration: /path/to/gunicorn.cfg and then in the gunicorn.cfg you can add [gunicorn] timeout = 90 graceful_timeout = 30 ### I applied the above changes to /opt/mailman/core/mailman-extra.cfg and created the gunicorn.cfg file. Restarted the docker container (mailman-core) and no access to Postorius due to no REST api. After restarting docker-mailman, I can't access Postorius due to the following error: ERROR 2020-07-20 20:16:27,351 15 postorius Mailman REST API not available Traceback (most recent call last): File "/usr/lib/python3.6/site-packages/urllib3/connection.py", line 160, in _new_conn (self._dns_host, self.port), self.timeout, **extra_kw File "/usr/lib/python3.6/site-packages/urllib3/util/connection.py", line 84, in create_connection raise err File "/usr/lib/python3.6/site-packages/urllib3/util/connection.py", line 74, in create_connection sock.connect(sa) ConnectionRefusedError: [Errno 111] Connection refused During handling of the above exception, another exception occurred: Traceback (most recent call last): File "/usr/lib/python3.6/site-packages/urllib3/connectionpool.py", line 677, in urlopen chunked=chunked, File "/usr/lib/python3.6/site-packages/urllib3/connectionpool.py", line 392, in _make_request conn.request(method, url, **httplib_request_kw) File "/usr/lib/python3.6/http/client.py", line 1254, in request self._send_request(method, url, body, headers, encode_chunked) File "/usr/lib/python3.6/http/client.py", line 1300, in _send_request self.endheaders(body, encode_chunked=encode_chunked) File "/usr/lib/python3.6/http/client.py", line 1249, in endheaders self._send_output(message_body, encode_chunked=encode_chunked) File "/usr/lib/python3.6/http/client.py", line 1036, in _send_output self.send(msg) File "/usr/lib/python3.6/http/client.py", line 974, in send self.connect() File "/usr/lib/python3.6/site-packages/urllib3/connection.py", line 187, in connect conn = self._new_conn() File "/usr/lib/python3.6/site-packages/urllib3/connection.py", line 172, in _new_conn self, "Failed to establish a new connection: %s" % e urllib3.exceptions.NewConnectionError: <urllib3.connection.HTTPConnection object at 0x7f96340a2e10>: Failed to establish a new con$ During handling of the above exception, another exception occurred: Traceback (most recent call last): File "/usr/lib/python3.6/site-packages/requests/adapters.py", line 449, in send timeout=timeout File "/usr/lib/python3.6/site-packages/urllib3/connectionpool.py", line 725, in urlopen Commenting out "configuration: /opt/mailman/gunicorn.cfg" brings Postorius back up. I am really frustrated here. All I want to do is export a 3000 member list and I can't. Updating Mailman 3 using new Docker images shouldn't break a stable installation either. Please help. Brian

Fwd: HOWTO: Mailman 3 Equivalent of "Accept: @all"
by Abhilash Raj July 21, 2020

July 21, 2020

Please use the mailman-users(a)mailman3.org list for questions related to Mailman 3 usage. Abhilash ----- Original message ----- From: "hmills(a)t-online.de" <hmills(a)t-online.de> To: "mailman-users-owner(a)mailman3.org" <mailman-users-owner(a)mailman3.org> Subject: HOWTO: Mailman 3 Equivalent of "Accept: @all" Date: Tuesday, July 21, 2020 9:31 AM Greetings, I have a question concerning usage of mailman3 (not an installation issue). Previously we used mailman2 & changed to mailman3 some months ago. "We" being a sports club located in Northern Germany. I guess I'm the "List Administrator" & "Moderator" - a colleague is the "Site Administrator". We use a number of maillists - one for "all" members and further ones e.g. for "instructors", "juniors" and so on. With mailman 2 it was possible to add "Accept: @all" in the configuration of the smaller maillists such as "instructors" thus enabling any club member to mail to the "instructors" but mails amongst the "instructors" remained just with themselves. Up to now we cannot do this with mailman3 which means I have to frequently approve mails (with the associated delay). I'm told (but not "how to do it") that with the recent update to mailman3 which our Site Administrator has installed it should be possible to do the "Accept: @all" mechanism - or similar. Could some kind soul please simply explain how I can achieve this? Best Wishes Howard -- thanks, Abhilash Raj (maxking)

Mail going to Held Messaging even the moderation is set to Accept Immediately
by Shashikanth Komandoor July 21, 2020

July 21, 2020

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 in production environment from the past 2 months almost. Recently I observed a peculiar case. There is a list say testlist(a)lists.testdom.com has a member say testuser(a)testdom.com whose Moderation attribute is set to "Accept immediately (bypass all other rules)". It is expected that the mail should be delivered to the recipients without being held irrespective of the body content as per my knowledge. (Correct me if I am wrong). But the mail went to "held messages" and is waiting for pending approval. The same user if he sends a normal and simple test mail, it is getting delivered automatically without coming to the "held message". And the same mail (which went to "held messages") is tried to be sent by another member whose moderation attribute is also set to "Accept immediately" only but observed the same effect as the message going to the "held messages". As per my understanding on Mailman 3, if the moderation attribute is set to "Accept immediately (bypass all other rules)" then without checking any rules, it should be delivered to the recipients of the list irrespective of the message or body of the message but is there any such checking if the body content or subject or any thing else is checked even if the moderation bit is set to "Accept immediately". Please help me to resolve this issue. Also, please let me know if I need to share any details. -- Thanks & Regards, Shashi Kanth.K 9052671936 <https://www.avast.com/sig-email?utm_medium=email&utm_source=link&utm_campai…> Virus-free. www.avast.com <https://www.avast.com/sig-email?utm_medium=email&utm_source=link&utm_campai…> <#DAB4FAD8-2DD7-40BB-A1B8-4E2AA1F9FDF2>

Sudden increase in "***UNCHECKED***" in email subjects

Hi all, I have just noticed a big jump in the number of emails going out with "***UNCHECKED***" added to the subject line. Some of these are from users who had their moderation set to "Accept Immediately," but even after I change that to "Default processing" I am still getting those messages. The default action for members is "Default processing" Any ideas what settings I am missing? Thanks, Dave C -- https://bcc2020.github.io/ https://galaxyproject.org/

Confusing mailman user model
by Gilles Filippini July 19, 2020

July 19, 2020

Hi, I'm trying to understand the Mailman user model, and I'm confused about the respective roles of tables 'auth_user' and 'user'. Both have an 'id' column referred to as 'user_id' when used as a foreign key. But there seems to be no relation at all between them as they use different ids for the same user. Our mailman server was migrated from mailman2 to mailman3 about 1.5 year ago, and there is an inconsistency I'd like to fix: 2 of our users have a registered Mailman account with their respective email addresses in table 'auth_user', but these very same addresses in the 'address' table are linked to another old admin account in the 'user' table. Then if add one of these addresses as a domain owner, it it the old admin address which is selected instead. How could I fix that? Thanks in advance, _g.

Hi there, i also deleted the website example.com, while I tried to configure my mailman 3 site. Now I get a Server-error, when I try to open my mailman3 sites: "An error occurred while processing your request" I tried to fix this problem by changing the SITE_ID=2 in my settings_local.py. But nothing helped, also the SITE_ID=0 did change nothing. I made a "/etc/init.d/apache2 restart" to ensure, that the settings are loaded again, but it didnt help. Is there anything I can do, besides reinstalling all django and mailman 3? Mailman Version 3.2.1, Python 2.7.16, Django 1.11.28 Thanks for any hints :-) Wolfgang

The Use of Hyperkitty as a Forum and Archiver
by Brian Carpenter July 15, 2020

July 15, 2020

Dear Mailman 3 Users, Since Mailman 3 includes a forum feature via Hyperkitty, I would like to know the following: - Has the forum feature (Hyperkitty) of MM3 been received well by your list members or is it mostly ignored? - Do you see an increase in the use of HK as a forum from your list members? - What kind of feedback have you received from your list members considering the forum function of MM3? Positive or negative? - Do you think HK is received well by your list members as an archiver and do you think it provides a better user experience for viewing/searching archives vs Pipermail of MM2? Thank you for anything you shared. I am very curious to know the state of Hyperkitty among the Mailman 3 user community. -- Please let me know if you need further assistance. Thank you for your business. We appreciate our clients.
