Feature request, hyperkitty, low volume lists
by Alain D D Williams Jan. 9, 2025

Jan. 9, 2025

I host several low volume mail lists. Typically these are announcement lists where low volume is deliberate -- too many emails and people might unsubscribe. These lists are archived but most months there are not any postings. Browsing the archives can mean much clicking to find content, this is done better with mailman2. My request is to make finding content easier. Possibilities: • On the summary (left hand side) put the number of posts after the month name • Only show months (left hand side) where there are any posts For an example see: https://fridayfolk.phcomp.co.uk/mailman3/hyperkitty/list/announce@fridayfol… (There is one post in November) Regards -- Alain Williams Linux/GNU Consultant - Mail systems, Web sites, Networking, Programmer, IT Lecturer. +44 (0) 787 668 0256 https://www.phcomp.co.uk/ Parliament Hill Computers.

Mailman3 Docker persmission denied
by Commander456 Jan. 6, 2025

Jan. 6, 2025

Hello everyone, I recently installed the mailman-core Docker image (Version 0.5) and tried to create a list using the mailman commands inside the container. I used the --notify argument but doesn't receive any mail (I'm the list owner), However, inside the mailman.log I get the following error: Jan 06 20:54:25 2025 (156) Uncaught runner exception: [Errno 13] Permission denied: '/opt/mailman/var/queue/virgin/1736196864.6488764+2c5d24f89f86715d3deb3d0032735050cb9e29f8.pck' Jan 06 20:54:25 2025 (156) Traceback (most recent call last): File "/usr/lib/python3.12/site-packages/mailman/core/runner.py", line 164, in _one_iteration msg, msgdata = self.switchboard.dequeue(filebase) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/usr/lib/python3.12/site-packages/mailman/core/switchboard.py", line 150, in dequeue with open(filename, 'rb') as fp: ^^^^^^^^^^^^^^^^^^^^ PermissionError: [Errno 13] Permission denied: '/opt/mailman/var/queue/virgin/1736196864.6488764+2c5d24f89f86715d3deb3d0032735050cb9e29f8.pck' Jan 06 20:54:25 2025 (156) Skipping and preserving unparseable message: 1736196864.6488764+2c5d24f89f86715d3deb3d0032735050cb9e29f8 These are my file permissions: mailman-core:/opt/mailman/var/queue# ls -l total 48 drwxrwx--- 2 mailman nogroup 4096 Jan 6 17:11 archive drwxrwx--- 2 mailman nogroup 4096 Jan 6 20:54 bad drwxrwx--- 2 mailman nogroup 4096 Jan 6 17:11 bounces drwxrwx--- 2 mailman nogroup 4096 Jan 6 17:11 command drwxrwx--- 2 mailman nogroup 4096 Jan 6 17:11 digest drwxrwx--- 2 mailman nogroup 4096 Jan 6 17:11 in drwxrwx--- 2 mailman nogroup 4096 Jan 6 17:11 nntp drwxrwx--- 2 mailman nogroup 4096 Jan 6 17:11 out drwxrwx--- 2 mailman nogroup 4096 Jan 6 17:11 pipeline drwxrwx--- 2 mailman nogroup 4096 Jan 6 17:11 retry drwxrwx--- 2 mailman nogroup 4096 Jan 6 17:11 shunt drwxrwx--- 2 mailman nogroup 4096 Jan 6 20:54 virgin mailman-core:/opt/mailman/var/queue/virgin# ls -l total 0 Do you have any idea what I'm doing wrong?

Hi As a moderator I receive an email each day for "Held Unsubscriptions" for a subscriber that was unsubscribed by the Owner sometime ago (using "Mass operations"). +++++++++++++++++++++++++++++++ The listname(a)domain.com list has 1 moderation requests waiting. Held Unsubscriptions: User: bart(a)example.com Please attend to this at your earliest convenience. +++++++++++++++++++++++++++++++ There is nothing showing under "Subscription requests > Pending approval". Could anyone tell me how I can stop these email notifications? I have access to the mailman shell and the databases. Thanks, Mark

possible backscatter attack using Mailman3 servers
by David Newman Jan. 5, 2025

Jan. 5, 2025

Greetings. On a system running Mailman 3.3.9 and Postfix, I'm seeing about 20-30 entries per day in the Postfix queue where it appears a Gmail user signs up for a mailing list that requires confirmation, and Gmail responds that the user is too busy to handle requests. There are no publicly advertised email lists on this server, and I don't ever see anything in the Mailman logs indicating the user ever tried signing up. I've pasted the mail.log transaction below, with only slight obfuscation: - "mail10.example1.com" is this server's canonical hostname - lists are hosted on "lists.example2.com" and "mail.example3.com" - "someuser9413(a)gmail.com" is the user supposedly signing up Thanks in advance for clues on determining where these requests are coming from, and how I might block them. I have a strong interest in having my server not amplifying backscatter traffic like this. Alternatively, if this is a Postfix problem, please let me know that too. dn Jan 3 10:29:22 mail10 postfix/postscreen[4052406]: CONNECT from [::1]:55274 to [::1]:25 Jan 3 10:29:22 mail10 postfix/postscreen[4052406]: WHITELISTED [::1]:55274 Jan 3 10:29:22 mail10 postfix/postscreen[4052406]: using backwards-compatible default setting respectful_logging=no for client [::1]:55274 Jan 3 10:29:22 mail10 postfix/smtpd[4052407]: connect from localhost[::1] Jan 3 10:29:22 mail10 postfix/smtpd[4052407]: discarding EHLO keywords: CHUNKING Jan 3 10:29:22 mail10 postfix/smtpd[4052407]: 4YPsYG1X2xzHQfw: client=localhost[::1] Jan 3 10:29:22 mail10 postfix/cleanup[4052628]: 4YPsYG1X2xzHQfw: message-id=<173592896219.2314.15515568084960961396(a)mail10.example1.com> Jan 3 10:29:22 mail10 postfix/smtpd[4052407]: disconnect from localhost[::1] ehlo=1 mail=1 rcpt=1 data=1 quit=1 commands=5 Jan 3 10:29:22 mail10 postfix/qmgr[3635053]: 4YPsYG1X2xzHQfw: from=<postmaster(a)example2.com>, size=901, nrcpt=1 (queue active) Jan 3 10:29:22 mail10 postfix/10025/smtpd[4052639]: connect from localhost[127.0.0.1] Jan 3 10:29:22 mail10 postfix/10025/smtpd[4052639]: discarding EHLO keywords: CHUNKING Jan 3 10:29:22 mail10 postfix/10025/smtpd[4052639]: 4YPsYG33SkzHSdN: client=localhost[127.0.0.1] Jan 3 10:29:22 mail10 postfix/cleanup[4052628]: 4YPsYG33SkzHSdN: message-id=<173592896219.2314.15515568084960961396(a)mail10.example1.com> Jan 3 10:29:22 mail10 postfix/10025/smtpd[4052639]: disconnect from localhost[127.0.0.1] ehlo=1 mail=1 rcpt=1 data=1 quit=1 commands=5 Jan 3 10:29:22 mail10 postfix/qmgr[3635053]: 4YPsYG33SkzHSdN: from=<postmaster(a)example2.com>, size=1939, nrcpt=1 (queue active) Jan 3 10:29:22 mail10 amavis[4017234]: (4017234-09) Passed CLEAN {RelayedInternal}, MYNETS/MYUSERS LOCAL [::1]:55274 ESMTP/ESMTP <postmaster(a)example2.com> -> <someuser9413(a)gmail.com>, (), Queue-ID: 4YPsYG1X2xzHQfw, Message-ID: <173592896219.2314.15515568084960961396(a)mail10.example1.com>, mail_id: P9P7GnranpAW, b: Zp0DirpBL, Hits: -, size: 900, queued_as: 4YPsYG33SkzHSdN, Subject: "[mail.example3.com] Please Confirm Your Email Address", From: <postmaster(a)example2.com>, helo=mail10.example1.com, dkim_new=dkim:example1.com, 217 ms Jan 3 10:29:22 mail10 postfix/amavis/smtp[4052633]: 4YPsYG1X2xzHQfw: to=<someuser9413(a)gmail.com>, relay=127.0.0.1[127.0.0.1]:10024, delay=0.24, delays=0.02/0/0.01/0.21, dsn=2.0.0, status=sent (250 2.0.0 from MTA(smtp:[127.0.0.1]:10025): 250 2.0.0 Ok: queued as 4YPsYG33SkzHSdN) Jan 3 10:29:22 mail10 postfix/qmgr[3635053]: 4YPsYG1X2xzHQfw: removed Jan 3 10:29:22 mail10 postfix/smtp[4052642]: Trusted TLS connection established to gmail-smtp-in.l.google.com[2607:f8b0:4023:c0d::1b]:25: TLSv1.3 with cipher TLS_AES_256_GCM_SHA384 (256/256 bits) key-exchange X25519 server-signature ECDSA (prime256v1) server-digest SHA256 Jan 3 10:29:22 mail10 postfix/smtp[4052642]: 4YPsYG33SkzHSdN: host gmail-smtp-in.l.google.com[2607:f8b0:4023:c0d::1b] said: 450-4.2.1 The user you are trying to contact is receiving mail at a rate that 450-4.2.1 prevents additional messages from being delivered.

mailman transfer from 2to3
by Daniel Germer Dec. 28, 2024

Dec. 28, 2024

Hello all, I am new to mailman3, once upon a time I had mailman installed on my server, but had trouble with many things, especially virtual hosts not possible in mailman2... However on https://docs.mailman3.org/en/latest/pre-installation-guide.html#what-do-i-n… are no system requirements for the installation. I assume, that I cannot just install mailman3 on a regular webhoster, but there is no section: You need to have root access to a Linux system with at least 8/16/31/64GB RAM and at least 1/2/5/7 GB of free diskspace (ssl or hard-disk?) You need so and so much for 100/1000 Lists with 10/100/1000 Users each and 5/50/500 Mailings per day... where do I find that information? what is the smallest possible machine to run mailman3 on? Can I run it on a raspberry pi? regards, Daniel

Dec. 26, 2024

Dears, I am currently cleaning up a huge list of non-members. In contrast to the members list where I can select multiple entries and delete them at once, this is not possible in the list of non-members? Can this be enabled in a future release? Thank you and kind regards Torge

MTA setup
by Arte Chambers Dec. 24, 2024

Dec. 24, 2024

I've got a new installation of Mailman 3 setup, however I am having some issues I'm not sure how to troubleshoot. Mailman is successfully sending invite emails however user messages sent to the list are not being sent to subscribers. Also in Hyperkitty none of my test messages to the list are showing up in the archive. I am using Postfix with an SMTP relay hosted at Brevo.com (formally sendinblue).

Suggestion on Mailing Lists page

Dec. 24, 2024

This is the page that lists the mailing lists that I have. It would be really useful if there was an indication next to each list if that list required attention, eg an email awaiting moderation.

MM2 to MM3 Archives Loading
by Joshua Bushe Dec. 22, 2024

Dec. 22, 2024

Hi everyone, I’ve successfully converted a list from Mailman 2 to Mailman 3, and most things are working smoothly. However, I’m encountering an issue with the archives in the GUI: Problem: The archives don’t load on the overview page. Odd Behavior: If I use the search function, the archives appear as expected, but they remain invisible on the main overview. Has anyone encountered this issue or have suggestions for troubleshooting? Thanks in advance for your help!
