Best practice when deleting a mailing-list (archiving an old list)
by Marc SCHAEFER Sept. 10, 2024

Sept. 10, 2024

Hello, With Mailman2, my list deletion procedure was quite simple: - export the list configuration with config_list - export the list members - archive the archives somewhere - remove the aliases manually - delete the list I think that with Mailman3, the above can be done as follows: - export the list configuration with https://docs.mailman3.org/projects/mailman/en/latest/src/mailman/rest/docs/… - export the list members with https://docs.mailman3.org/projects/mailman/en/latest/src/mailman/model/docs… - archive the archives somewhere: this is my main question - remove the aliases manually: this is automatic - delete the list So, is there a simple way to export a list's archives in a way it can be reimported, now that everything seems to be in the database? Archiving the whole database is an issue here (its compressed dump size > 2 GB). Thank you for your ideas or pointers!

Mass Subscribe caused Delivery Status to become "unset"
by chad.hays86＠gmail.com Sept. 9, 2024

Sept. 9, 2024

One of the admins on our Mailman site said they recently performed a mass subscribe operation on list, however they noticed that for each user they subscribed, their "Delivery status" was unset, so they weren't receiving email updates whenever there was new activity on the list. They had to go in after the fact and manually set it to "Enabled" for each user that was subscribed via the mass subscription operation. Is this behavior expected? During the mass subscribed, pre-confirm, pre-approved, and pre-verified checkboxes were all checked.

It takes a very long time to display the list archives
by bryan.kartzman＠yu.edu Sept. 9, 2024

Sept. 9, 2024

When I try to display the archives of any list in my mailman3 installation it takes forever for it to display. We are talking a good three or four minutes. It doesn't matter if there are 100 messages in the archives or just one. We are using postgres for the mailman3 and django databases. On the server, when I click to display a list's archives, I see the process "gunicorn: worker [gunicorn]" is using nearly 100% of available CPU.

when on particular person sends a message to the list dozens of OTHER users have their bounce score incremented
by Ken Alker Sept. 9, 2024

Sept. 9, 2024

We have been experiencing a strange anomaly. We are running a small-ish list. When a particular subscriber to the list sends an email to the list, a couple of dozen (or more) of the recipient's of the message end up with their bounce scores incrementing. This particular subscriber uses about three different email addresses when he sends his messages and every one of them causes this behavior. There is another subscriber who also causes this behavior when he sends an email to the list, but only one of the two email addresses he sends from causes this behavior. There is a third person who causes this behavior every time. There are dozens of other subscribes who don't generate this behavior when they send to the list. I can't figure out why this is occurring. I *assume* that Mailman re-writes the headers to add DKIM, etc., before sending them to the list recipients but it sure seems like something in the header from the original sender is ending up in the final header (or something is LACKING) which is not liked by the recipient's MTA's. It doesn't seem like a subscriber sending an email to the list should be able to cause this behavior - but I'm no expert. The recipients appear to be using many different mail platforms (ie. their addresses are not all, or even mostly, @google.com or some other domain; the recipients appear to be a pretty good cross section of platforms). This has been going on all year (maybe longer). Any help or troubleshooting suggestions would be greatly appreciated.

Is there an easy way to tell which lists on my Mailman 3 installation are being used (i.e. received posts in the last two or three months)?

Setting base_url for the domain to use it in the templates.
by Timour Bakeev Sept. 8, 2024

Sept. 8, 2024

Hi all! I'm trying to use extended placeholders for the [templated texts](https://docs.mailman3.org/projects/mailman/en/latest/src/mailman/res… in the message footer that are sent to the members: > Along with these, Mailman supports placeholder as URLs for web interface when `base_url` property is set at the Domain level. These include: > domain_url - URL to homepage for a domain. > mailinglist_url - URL to homepage for a mailinglist. > held_message_url - URL to page for handling all held messages. > pending_subscriptions_url - URL to page for handling pending subscription requests. > pending_unsubscriptions_url - URL to page for handling pending unsubscriptions. The REST API docs mention `base_url` as the property of the domain: [domain URLs](https://docs.mailman3.org/projects/mailman/en/latest/src/mailman/rest… But my attempts to use REST API to set it fail: ``` curl --user 'restapi:restpass' \ -X PATCH \ -H "Content-Type: application/json" \ -H 'Accept: application/json' \ -d '{ "base_url": "https://example.net/mailman3" }' \ http://localhost:8001/3.1/domains/example.net | jq '.' { "title": "400 Bad Request", "description": "Unexpected parameters: base_url" } ``` My MM3 instance is the latest(3.3.9), provided by the maxking mailman-core docker image. It looks like there is a lot of confusion about `base_url` in general, as hyperkitty seems also use the property with the same name, for example: https://lists.mailman3.org/hyperkitty/list/mailman-users@mailman3.org/threa… So what is the correct way to get those extended placeholders to work in the templates? It's also not clear to me, what the the primary domain should be for the installation - server hostname, as in `lists.mailman3.org` or the domain, used in the mailing list(s) itself, like `mailman3.org` for mailman-users(a)mailman3.org... With best regards, Timour Bakeev

Can you use @list to include members in accept these non-members in v3?
by Lieuallen, Thomas Otis Sept. 5, 2024

Sept. 5, 2024

In Mailman v2, one could use @listname in ‘accept_these_nonmembers’: A line consisting of the @ character followed by a list name specifies another Mailman list in this installation, all of whose member addresses will be accepted for this list. I don’t see this option listed in version 3. Is it no longer supported/allowed? Is there another option? We often send email to lists of lists and have loved that @listname option to help us deliver email to 20+ lists without needing to approve the emails each time or reconfigure all the lists when another sender needs to be added. Thank you Tom Lieuallen Oregon State University

security app causing django Internal Server Error: /archives/search emails
by sun zi Sept. 5, 2024

Sept. 5, 2024

Greetings, I have set up a few lists and all seems to be working as expected, however I get a large number of emails due to internal server errors received when my security application is testing exploits to list URLs such as the following: https://<mylistdomain>/archives/search?sort=177120&cauft=&page=1&q=../../../../../../../../../../tmb/wditeteet424465304.txt. Is there any django logging filter changes that can be made to avoid receiving these emails? Any assistance would be greatly appreciated. Thank you!

Assistance Needed for Ubuntu 22.04 Mailman3 Installation and Configuration
by smiithjohn90＠gmail.com Aug. 31, 2024

Aug. 31, 2024

Hello Everyone, I'm trying to install Mailman3 on an Ubuntu 22.04 server right now, and I've run across a few obstacles that I'd like help with. I've followed the installation instructions, but I'm having trouble in a couple places, so I was hoping an experienced someone might help me out. This is what I have completed thus far: - I used the apt-get package manager to install Mailman3. - PostgreSQL was configured as the database backend. - Postfix was installed and set up to function as the Mail Transfer Agent (MTA). - Assemble Postorius, Hyperkitty, and the Mailman3 core. Problems I'm Having: Postorius and Hyperkitty Connectivity: I'm having problems making sure that the Mailman core is correctly connected to Postorius and Hyperkitty. I get a 502 Bad Gateway error when I try to access the web interfaces. Despite checking my specifications, I am unable to identify the problem. Problems with Email Delivery: I'm also having trouble with email delivery. Although Mailman appears to be receiving emails, it is not appearing to be sending any out. I think there might be a Postfix problem, but I'm not sure how to solve it. Generally Suggested Practices: Are there any particular security best practices I should be aware of when it comes to Mailman3 installations? I want to confirm that my configuration is both performance- and security-optimized. https://lists.mailman3.org/archives/list/mailman-users@mailman3.org/thread/… https://www.igmguru.com/salesforce/salesforce-developer-training https://lists.mailman3.org/archives/list/mailman-users@mailman3.org/thread/… I would be grateful for any advice or resources! It would be really beneficial if someone with a similar setup could share their settings or troubleshooting procedures. Thank you in advance.
