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.

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?

Excessive or fatal bounces issue
by Florin Pasăre Nov. 23, 2023

Nov. 23, 2023

Hello, I've been having some issues lately. We are using Mailman 2.1.15. I've looked over the FAQ but the only thing that I could find is to contact the ISPs and ask to be whitelisted - am I understanding this correctly? Here is a brief description of the issue: Our server hosts 5 listserv, the biggest one counts over 530 subscribed members from 55 different countries. We had received sporadic bounces triggered by emails sent to these lists since the install of the server in 2016, but in the last months the number of bounces we get has increased. We receive these bounce notifications informing us that the given *subscription has been disabled* due to *excessive or fatal bounces *(up to around 30 bounce notifications triggered by a single email sent to one of the listservs). Every time we get such notifications, we untick the bounce under “nomail [reason]" in the admin management site for each of the email addresses that haven been disabled by the system. Furthermore, it has happened several times in the past few months that a number of email addresses have been automatically removed from the listservs (at the same time, from different countries). We have not found an explanation for why this happens or a solution, so the only thing we are able to do is to manually add them back to the listservs. We have also asked these colleagues for which we have received bounces to check whether there is anything blocking the listservs’ emails from their side (note that many of them work in ministries or agencies with strong security features), and to add the server IP to the white list, but the problem persists. Thank you for your time, Florin Pasăre,

Hide list address?
by Ricardo Kleemann Nov. 17, 2023

Nov. 17, 2023

Hi, Is there any way to configure Mailman such that, for an announcement-only type list, when a message is sent to the list, the To: shows the member's address, rather than the list address? Some list software allows the ability to hide the list address itself, so that address is not advertised. I couldn't find any configuration specific to that.

Hevy resource footprint forces backdrop to mailman 2.1
by Martin Lorenz Aug. 5, 2023

Aug. 5, 2023

Greetings, after many years of smoothly running a mailman2 instance I had to migrate my virtual server to a new provider. There I found, that mailman2 was no longer supported and tried to migrate to mailman3 .. with much pain and no success. Mailman3 keeps crashing my v-server and swallows almost every mail sent to any of the migrated lists. So I wanted to switch back to mailman 2.1.39 by installing from the source package and found that this also fails due to missing python2 support. How to solve this? Thank you very much

List Won't Send Mail
by David Andrews July 28, 2023

July 28, 2023

I have a list that won't send out mail. I believe that all the settings are correct, but I could have missed something. I am running Mailman 2.1.39 cPanel, and I have access to the command line. I have a list that I needed to modify settings. It was established by a prior administrator, to whom I have no contact. I can access admin UI, and modified everything. However, at the bottom of the Administrative page, where it says "list run by" the domain it shows is incorrect. It is a domain used for mail only on my installation. The list comes up on my list of lists pages, but when I mail to it, it get permanent error list not found. I hope this makes sense! Dave p.s. I don't know why or how, but I think the list isn't completely registered with the system. Also, I was able to establish a similar list, with different capitalization of name, the both show up on admin page, but not sure how to get rid of the bad one because it doesn't show up in the cPanel UI. Dave

Where's the installation directions / source, etc, please?
by Richard＠KarmannGhia.org July 20, 2023

Hi All, I used to use plain-ole mailman, WAY back in the '90s, BEFORE mailman2 and LONG before mailman3... And I sure wish mailman2 had been done by people who had a sense for the challenges for normal non-developer system managers to deal with the software they actually developed. I'm sure it's fine if you're already a Django programmer and use "containers" all the time, but I'm not a Django fanboy, don't ever care to be, and think the idea of containers is inappropriate technology for a hell of a lot of use-cases, especially a small, self-run, no-budget installation. But maybe the worst is that the developers of that stuff can't be bothered to create a wrapper so you've got ONE consistent way to do things from the command line?! WTF?! What the he... OK, no reason to get into a rant. Ya know, I tried it, gave it a fair attempt, and given my experience, if I wrote what I think of it here, I might get banned! So, I'm done with it and want to go back to the old stuff. I'll happily build from source, etc. But my simplistic web searches haven't returned results and I'm afraid I didn't keep great records about it back when since it was just a part of my Fedora package system! So, any pointers for this long-in-the-tooth Fedora Sys Admin? Thanks folks, Richard (from somewhere in San Franciso's east bay area...)

Python 2.7.15, etc, vs Python3...
by Richard＠KarmannGhia.org July 19, 2023

July 19, 2023

Inching forward here folks, trying to get Mailman 2.1.39 going. I get to the point it calls Python and it dies with: checking for python... /usr/local/bin/python checking Python interpreter... configure: error: ***** No Python interpreter found! ***** Try including the configure option ***** --with-python=/path/to/python/interpreter I checked; there are only 245 different Python packages installed! -slap-forehead- What was I thinking! OF COURSE it requires more of 'em! If I type python and then double-hit tab, I get: python3 python3.11 python3.11-config python3.11-x86_64-config python3-config python-argcomplete-check-easy-install-script python-argcomplete-tcsh python-config ...I tryed to install the corresponding package, which appears to be Python 2.7.15, it as a package but it couldn't be found by the usual package manager OTOH, can Python3 (what's there now) be THAT backwards incompatible?! SURELY I can make it happy somehow, right? How about an ln -s of /usr/local/bin/python to the one in my path? Do I have to install the old Python from source, TOO?! Anybody know? Thanks, R P.S. It seems BIZARRE to me that we have the good ole cc and gcc that just work after however many decades, yet the modern developers seem just not have a clue how - or just don't care - to code for longevity - what, the code to get python has to enter python3 now or just die? Really? I'm sure you can easily tell I strongly disagree with modern practices about dependencies; "computer science" has gone backwards, at least in strategy! ... But I digress...
