migration plan and auto responder
by Mohsen Masoudfar 23 Jul '20

23 Jul '20

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 22 Jul '20

22 Jul '20

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 22 Jul '20

22 Jul '20

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 21 Jul '20

21 Jul '20

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 21 Jul '20

21 Jul '20

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
by Dave Clements 20 Jul '20

20 Jul '20

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 19 Jul '20

19 Jul '20

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.

Creating new lists

Hi, I'd like to delegate lists creation to a couple of other users. I've added their email addresses as domain owners, but still they don't have the "Create New List" button available. Which condition a mailman user has to fulfill to be allowed to create new lists? Thanks, _g.

Also deleted website example.com
by w.schoener＠alp.dillingen.de 17 Jul '20

17 Jul '20

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
