Mailman3 memory footprint
by Marc SCHAEFER June 6, 2024

June 6, 2024

Hello, It seems the mailman & mailman-web memory footprint are somewhat big. It looks a lot of instances are started. I have seen this: https://gitlab.com/mailman/mailman/-/issues/1050 and added this to the end of /etc/mailman3/mailman-web.py: Q_CLUSTER = { 'workers': 2, 'timeout': 300, 'save_limit': 100, 'orm': 'default', 'poll': 5, } However, it does not seem to really reduce the memory footprint. Any other suggestions? Thank you.

Mailman3 doesn't send Mails to users (Debian12 with Plesk)
by marcus＠mbautze.de June 6, 2024

June 6, 2024

Hello, i already send this question to the plesk-forum but it seems that nobody there can help me :-( After updating from Debian 10 to 11 to 12, I now have mailman3 running on my server I then converted all lists from Mailman2 to Mailman3 following the instructions from mailman. I can access it via the web interface, manage everything etc. When I register on the web interface, I also receive the corresponding mails from Mailman (forgotten password...) Mails are also arriving, at least mails that are not allowed go into the mails to be approved. The problem, however, is that it does not send out any mails, nor do they appear in the archive. When I look in the Mailman-Log I find: May 16 01:44:55 2024 (6833) Cannot connect to SMTP server localhost on port 25 May 16 01:48:15 2024 (61252) error opening connection to nntp_host: localhost [Errno 111] Connection refused May 16 01:48:15 2024 (61252) NNTP error for list vereinsmitglieder(a)ludothek.de: [Errno 111] Connection refused The configuration of Mailman.cfg looks like this: incoming: mailman.mta.postfix.LMTP outgoing: mailman.mta.deliver.deliver smtp_host: localhost smtp_port: 25 smtp_user: smtp_pass: lmtp_host: 127.0.0.1 lmtp_port: 8024 In Mailman manuals I find hints that the transport routes have to be added to the Postfix-config. Doesn't Debian/Plesk do this automatically? Does anyone else have an idea what I need to change to get my mails out? I did the conversion from mailman2 to mailman3 with root because it didn't work with "sudo -u list "m, but the files stored in the file system all belong to list, so that shouldn't be the problem.

Sending to mangled 'From' addresses.
by hansen June 5, 2024

June 5, 2024

All, Due to the DMARC mitigation action ‘Replace From: with list address’, it happens often on my lists that someone sends a message to a mangled address, hoping that the message goes to the person listed as the sender. This happens mostly because the mail clients collect previous addresses and use them when as type-ahead candidates for new messages, which may be unrelated to the lists. For example, say the mail client captures my address as “Allan Hansen via <listname>” <listaddress> then later, when the person wants to send a message to me, the type-ahead puts this string in the ’To:’ field: “Allan Hansen via <listname>” and, to make it worse, the actual email address, <listaddress>, is often hidden. The result is that the email gets sent to the list instead of to me, together with (often) personal and (sometimes) embarrassing information. Is there a way to reject messages sent to recipients where the name part of the recipient is of the above format, i.e., "Allan Hansen via <listname>" In other words, filtering is done on the name part of the recipient, not the address part. Should I get onto the other list to request this as an enhancement? Yours, Allan

import21 detailed usage instructions in 2024
by Keith Christian June 3, 2024

June 3, 2024

1 Soon, I will be executing the first test imports from Mailman2.1 to Mailman3.9. 2 Planning to copy over the entire production Mailman2.1 to a new directory structure on the Mailman 3.9 machine. 3 Expecting that all .mbox and .pkl files will be present and no special work has to be done to bring them over will a "full" mailman2.1 copy. 4 Can the import21 program find the mailman2.1 .mbox and .pkl files on its own and process them? 5 Other than the mailman2.1 instance being shut down, any other prep that needs to be done? 6 Any special command line parameters to be aware of for import21? 7 Is there a list of troubleshooting steps for commonly encountered migration issues? Thanks. ------------------ Keith

import21 caused a few mails to be sent out
by Marc SCHAEFER June 2, 2024

June 2, 2024

Hello, After importing a (big > 3000 subscribers) list with import21, I noticed the following: 36 mails went out from LIST-NAME-bounces to subscribers, but they apparently all bounced. Could those be subscribers that Mailman2 saw bouncing and added the appropriate flag, and Mailman3 sent a probe after the import21? I checked for one of the e-mail address and: Mailman2: - that e-mail has the [X] R flag for "noncourriel" (no delivery) Mailman3: - that e-mail is Delivery mode Regular, Bounces to 0 NB: in MM2 and MM3, all users are in Hold for moderation, that's normal. In addition, there are a few mails in /var/lib/mailman/messages for example that same user: one file, showing a bounce from a remote server. So my questions: 1) is this behaviour to "probe" already disabled addresses normal, and not "port over" the "don't deliver"? 2) why are those messages held in messages/ ? 3) should I then, before running import21, clean the MM2 installation of all those users with [X] R flag? If yes, is there a simple command? Thank you for pointers or help. PS: there was no trafic on that imported mailing-list yet, it's a test.

Mailman sending email from user@example.com
by dgoldsmith＠sans.org May 30, 2024

May 30, 2024

I have defined an additional SITE in django and the SITE_ID value in /etc/mailman3/settings.py is set to reference that site's ID value. Messages for a list being distributed that are generating certain bounce errors are resulting in email from Mailman 3.x being sent to the list owners from the address user(a)example.com. Is there something else to update in the settings files, Django or the database to make it use the list owner email address tied to the domain of the site? Thanks, David Goldsmith

Django administration - User permissions
by advorkin＠cs.princeton.edu May 29, 2024

May 29, 2024

Hello, I'm trying to setup users with different permissions. For example: I created a group support with an ability to hyperkitty/mailing list/Can add/change/delete/view mailing list. Unfortunately, the user still does not have an ability to create mailing lists as the option does not exist. It does work when the user is set as "Superuser status". I've also tried giving every possible "available user permissions", but it didn't make a difference. Am I missing something? Thank you!

Installing Mailman3 under a Python Virtual environment running on RHEL9
by Andy Macheta May 29, 2024

May 29, 2024

Hi, So tried, without much success, to get Postorius working on my Mailman3 server and every internet trick& tip I tried did not work so decided to take a new approach as recommended at https://lists.mailman3.org/archives/list/mailman-users@mailman3.org/thread/… Used this reference: https://docs.mailman3.org/en/latest/install/virtualenv.html#installing-depe… which I know is more for Debian/Ubuntu systems but I was hoping that 90%+ would also work with Red Hat. Fell at the first hurdle with no packages available called "python3-dev" or "python3-venv" Is there anyone that has managed to install a running version of Mailman3 that has a working GUI whether it is on bare metal or Python virtual environment and if so, could they kindly let me know how they did it?? The closest I've come is a running command line version of Mailman3 which is fine for me of course but not for anyone else as they like access via web browser. Thanks in advance, Andy Macheta
