Mailman 3 January 2024 - Mailman-Users

Upgrade instructions
by G. Armour Van Horn June 7, 2025

June 7, 2025

I have a couple of Mailman lists on a server happily running 2.1.9 but I am also a moderator on a very active list that's running on 2.1.12. I do not host this list, just volunteer because I have some experience with Mailman. That list has started to get some significant bounces due to the DMARC issue that isn't addressed in this older version. The host intends to upgrade so that we can address that but they report that they haven't been able to make archives searchable in their experimentation with 2.1.16. I don't know if that search function is part of the more recent versions of Pipermail or if they've installed something else. I'm nervous about attempting to upgrade, given the paucity of documentation for that, particularly the fact that it tells me to use the same configuration options I used for the current install and I haven't a clue what those might have been. If I could find some more robust upgrade docs I'd like to try the upgrade in case I could contribute anything to the problem with the large list. Today I had to clear the bounce flags on 47 members. Not all that hard, but tedious. Van -- ---------------------------------------------------------- Sign up now for Quotes of the Day, a handful of quotations on a theme delivered every morning.

Sharing PHP or Scripts to a list
by patricia traore Nov. 8, 2024

Nov. 8, 2024

Hi All, I hope that I'm asking in the right place. We have just created a developers discussion public list in our organization with over 47 subscribers. My question is, in case someone shares some php codes in his message, will that code affect the corresponding html page of that message, while browsing the archive of messages publicly from a web browser? Or will pipermail instead display the shared codes as plain text? Thanks, Patricia Traore Project Lead, Maniflex Ltd | maniflexa.com

spamming
by Jim Dory Aug. 9, 2024

Aug. 9, 2024

I've got a new problem with my mailing list. I run a local announcements/trade list that should be of no interest to non-locals. I started seeing warnings from Yahoo about users marking messages as spam.. (I'm subscribed to Yahoo's Antispam Feedback. I never got other feedback loops from others - like Microsoft - to work). The messages that were being marked as spam by users were the confirmation emails sent by mailman to confirm a signup. To avoid having Yahoo shut down the list as spam (for its subscribers), I set the subscription to be approved by admin, so I could review who was trying to sign up. More and more now I'm seeing what appears to be spammers trying to subscribe, but I can't be sure. I'm seeing emails like: hirofeet0916(a)yahoo.co.jp (doesn't seem local) blvckpvlm(a)gmail.com (not many use user names such as that) fsafwcasgsadf2(a)gwqc.com (obviously not real - couldn't find domain with minimal searching) Plus some that could be local but how would I know. I could take off the "approval by admin" for subscription and just deal with anyone that is a problem afterward, but I do worry that they may be harvesting emails from subscribers, which are available in the reply-to headers. Don't know if there's anything I can do. Anyone else dealing with this? thanks. Jim

Editing Mailman's text files
by Pete Bell May 8, 2024

May 8, 2024

Hi. I'm a new member of this group but have been running an email list with Mailman for a long time. I am now setting a list up again and want to give a "look and feel" to the list which has more branding of my user group as a whole, and less of a Mailman-feel. I seem to remember that besides editing the public HTML pages, it is possible to edit the text files which Mailman automatically sends out for certain needs (such as 'approve.txt', 'adminsubscribeack.txt', 'invite.txt', and so on). A. Is this still the case? B. If so, where can I find them? (in case they've changed from the ones I have from long ago). C. Where do they need putting, so that Mailman can use them again? It's important that I should tell you that Mailman on my webhosts servers is a "server-wide" installation, and I don't get to edit anything which other clients to their servers need. This would be only for my own use, and as such I need to know where these files go in my own webspace, and how to get Mailman to use them instead of the default ones. I should also say that I have done this before, so unless the facility to do this has been ditched in recent years, I *should* still be able to do it ! Does Mailman perhaps look for these files somewhere in my webspace (which I have to give a specific name), and if it doesn't find them it goes on to find its default versions of these files? Thanks in advance for your help. Pete Bell, UK

Running two list with same email prefix
by Andrea Cappelli Feb. 27, 2024

Feb. 27, 2024

Hi all, I'm running a mail server with Debian Lenny, MTA is Postfix and i will use postfix-to-mailma.py script to run list I would set up Mailman for running mailing list with same email prefix on different domains, obvious with different list names For example we have ml.domain1.com and ml.domain2.net, i would like to have LISTADDRESS LISTNAME tech(a)ml.domain1.com tech-ml.domain1.com tech(a)ml.domain.2.net tech-ml.domain2.net In this way i can have the same address on differente domains and Mailman (my version is 2.1.11) can distinguish between lists because the list name is different. The list name will be also used to access web interface, so we have http://ml.domain1.com/mailman/admin/tech-ml.domain1.com http://ml.domain2.net/mailman/admin/tech-ml.domain2.net Is possible to accomplish this task? Any idea?

Find number of list members with "withlist"?
by Ralf Hildebrandt Jan. 23, 2024

Jan. 23, 2024

Sorry for the simple question, but how do I get the number of list members from a particular list using "withlist"? I'm trying to find lists with generic_nonmember_action set to 0 AND the number of list members exceeding a certain threshold. -- Ralf Hildebrandt Charité - Universitätsmedizin Berlin Geschäftsbereich IT | Abteilung Netz | Netzwerk-Administration Invalidenstraße 120/121 | D-10115 Berlin Tel. +49 30 450 570 155 ralf.hildebrandt(a)charite.de https://www.charite.de

Emails not being sent, but showing up in archives?
by Seeds of Success Jan. 3, 2024

Jan. 3, 2024

Hello, For the last two months or so, the emails that I send out on the mailman list do not get sent out to the subscribers, but do show up on the archived threads. I am not very mailman savvy, and have recently taken over admin roles from someone else. Any guidance on how I might address the issue would be appreciated!
