out queue backlog and delivery rate
by dancab＠caltech.edu April 11, 2022

April 11, 2022

We experienced an issue where our upstream mail protection gateway had an issue for a few hours. As a result out Mailman system was inundated with hundreds of messages within half an hour. Mail delivery is continuing at a snails pace and it is now 4 hours behind. I noticed that the system isn't overloaded either via CPU or Memory. It's just slowly "working on it". Are there rate limits that can be tuned for Mailman queues such as the "out" queue? Could this be IO related somehow? I'd expect there to be a CPU spike in that case. Please advise. Thanks in advance. ---- Dan Caballero Systems Administrator Academic Computing Solutions IMSS - Caltech https://imss.caltech.edu Is there anyway to

Looking for equivalent functions from mailman2
by Julian Kippels April 6, 2022

April 6, 2022

Hi, I am currently in the process of converting all lists from our mailman2 instance to mailman3 lists. In the process I found that some of the mm2-commands that I have come to rely on are no longer available for mm3. For example, how could I get an equivalent output to what "list_owners -w" would have given me on mm2? The same goes for the old "list_members"-command. Thanks in advance Julian Kippels

NNTP support
by Philip Colmer April 5, 2022

April 5, 2022

Hi I'm struggling to understand from the documentation what Mailman 3 supports with regards to NNTP. Does it only support sending emails to a configured news server or does it support NNTP access to itself by user client software? Thank you. Regards Philip

Active archivers and archiving and thread question.
by bob B March 31, 2022

March 31, 2022

Digging into the mailman3 world, and want to check my logic... We normally don't use archives, so I have "archive policy" set to "Do not archive this list" for our lists. However, the "archives" button is still there on the list info page, and if users go into it, they don't see anything, But they can click "start a new thread" which sends a message to the list, but since archiving is turned off, that message does not show up there. Am I understanding that correctly? if I have "Active archivers" disabled, that hides that area from the users, correct? Any reason why these are separated? why have an active archiver, if archiving is turned off -OR- archives are turned on, but no active archiver?

New install - The Message have no valid senders
by kenneth.karlsson＠eco.cept.org March 31, 2022

I have installed a brand spanking new Ubuntu 21.10, with postfix as SMTP server and mailman3-full apt package.. All checks out fine except when i deliver mails into MM. Mailman Core Version GNU Mailman 3.3.3 (Tom Sawyer) Mailman Core API Version 3.1 Mailman Core Python Version 3.9.7 (default, Sep 10 2021, 14:59:43) [GCC 11.2.0] I have a very simple mail command going into Postfix, and it receives it fine and relay it to MM (email address obscured below but of course a proper email address was used !): The command: EHLO contoso.com mail from: <xxx(a)xxx.com> rcpt to: <mhtest(a)list.cept.org> DATA This is a test message .

Problem with redirection when entering alias without a / at the end
by Jens Günther March 31, 2022

March 31, 2022

Hey there, I'm using Apache2 as the webserver, configured https://mailman.xyz.de as Web host. When I want to get to Mailman Starting Page now I need to Enter the following URL: https://mailman.xyz.de/mailman3/ to be directly redirected as expected to https://mailman.xyz.de/mailman3/postorius/lists/ -> works. Problem: When leave out the slash at the end and I ONLY enter the following URL: https://mailman.xyz.de/mailman3 -> then I'm wrongly redirected to a page, taht does not exist: https://mailman.xyz.de/mailman/postorius/lists/ -> 404 Where can I change this misbehaviour? In Apache-conf everything seems as it'S in the docs, for the vHost I do not have any other custom settings. Thank you in advance. By the way: Is there an easy way to redirect directly from https://mailman.xyz.de to https://mailman.xyz.de/mailman3/postorius/lists/ -> what would be a possibility for that?

Mails are stuck in Mailman Pipeline Queue
by Shashikanth Komandoor March 30, 2022

March 30, 2022

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 2000 lists with 64 GB RAM and 8 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 been seeing a special scenario suddenly: most of the mails that are sent to this server are going to the pipeline queue and not getting released from there. No configuration changes are done and I'm not sure why the mails are getting stuck there. I have recreated the list but no luck. Could not identify the root cause. Please help in this regard. -- Thanks & Regards, Shashi Kanth.K 9052671936

changing default preferred language of list
by Paul Paulchen March 29, 2022

March 29, 2022

Hi MM community, need a little advise. We're running mailman in a Docker Container (maxking) Mailman Core Version GNU Mailman 3.3.5 (Tom Sawyer) Mailman Core API Version 3.1 Mailman Core Python Version 3.8.10 (default, May 6 2021, 06:30:44) [GCC 9.3.0] As far as I understood, it should be pretty easy. My wish: every new list we create has a default value for the preferred language: de (instead of us) Like described here: https://lists.mailman3.org/archives/list/mailman-users@mailman3.org/message… We put the values in: [mailman] default_language: de "/etc/mailman.cfg" and "/opt/mailman/mailman-extra.cfg" Nothing changes. When I create a new list via Postorius, is see the preferred language is US. Am I missing something? Is the default always US? And I have to change it manually? Cheers in advance! Paul

Docker-Setup: example.com in test mails
by Bjoern Franke March 29, 2022

March 29, 2022

Hi, we are running a docker setup with mailman-web and mailman-core. To our confusion, test mails testing for bounces are sent from example.com From: Mailman <mailman(a)example.com> To: Mailman Bounces <mailman-bounces(a)example.com> instead of the list domain and are therefore often considered as spam. The list domain should be lists.ffnw.de. Did I miss some setting? Best Regards Bjoern
