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?

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.

Using cronjob to remove and add members to a mailing list
by Jerry Barnabee Aug. 10, 2022

Aug. 10, 2022

I want to be able to run a cronjob on my server that uses a php script to add new users and/or remove users from a mailing list. Not having any luck finding any simple examples. My thought is that the php script would get email addresses from a database (which I can do) and then feed them to a mailman command line to either add or remove a user. The cronjob is entered via Cpanel. Have several cronjobs that modify databases but have never tried something that would actually execute a unix command. Thanks, Pineyscripter

Mailman3 - from Whoosh to Xapian
by Kimmo L. July 5, 2022

July 5, 2022

Hello! My idea/plan is to replace Whoosh with Xapian. So far i have added this line inside settings.py: 'ENGINE': 'xapian_backend.XapianEngine', and installed pip package: pip install xapian-haystack Put i think its not enough and im missing something. If i try to do use "mailman-web rebuild_index", then i get some error messages: File "/opt/mailman/venv/lib64/python3.9/site-packages/xapian_backend.py", line 23, in <module> import xapian ModuleNotFoundError: No module named 'xapian' Any ideas what im missing ?

Held message notifications are not being sent to moderators
by Bruce Johnson June 22, 2022

June 22, 2022

We have numerous lists set as announcement lists by setting all members as moderated. However the moderators are not getting notifications for held messages; only the list owner is getting the notifications. This is a new-ish phenomenon, since I know they used to be sent to all the moderators, too. I can see the held messages in the vette logfile, and the smtp logfile shows the message to the list owner being sent, twice, but that’s it. vette: Jun 22 11:02:39 2022 (1248) Faculty post from johnson(a)pharmacy.arizona.edu held, message-id=<980174D2-74F6-4C25-8E2B-A21440D9D698(a)pharmacy.arizona.edu>: Post by non-member to a members-only list SMTP: Jun 22 11:02:41 2022 (1260) <mailman.358.1655920959.1248.faculty(a)pharmacy.arizona.edu> smtp to faculty for 1 recips, completed in 0.105 seconds Jun 22 11:02:41 2022 (1260) <mailman.360.1655920959.1248.faculty(a)pharmacy.arizona.edu> smtp to faculty for 1 recips, completed in 0.105 seconds As our office gets the emails for the list owners I was able to confirm the message ID for the notification. This is a problem, obviously. Is there any weird setting I could have made to break this? -- Bruce Johnson University of Arizona College of Pharmacy Information Technology Group Institutions do not have opinions, merely customs

Approved postings are not being delivered
by Francis Jayakanth June 22, 2022

June 22, 2022

Hi, I moderate and administrate a professional discussion list with about 6,000 subscribers. Most of the subscribers use Gmail, Yahoo, or other free email services. In the recent past, approved list postings are not being delivered to Gmail and Yahoo. I have subscribed to the list using my Gmail, Yahoo, and official email ids. I receive approved list messages only to my official email id, but not to my other two email ids. Our network support team tells me that the issue is because of the blacklisting of the email relay host used for mailing list service. Can someone help me to resolve the issue? I'm using Mailman 2.1.20 Thanks, Francis

Odd issue after setting Mailman to use https by default.
by Bruce Johnson June 21, 2022

June 21, 2022

Last week I got a notification from our SSL cert provider that the cert for our mailman server was expiring, so I renewed it, and realized that when I rebuilt the server last year I didn’t actually enable it in Apache. So I did, and added a rewrite rule in the httpd.conf to force all traffic to use https. After that, whenever a moderator or admin tried to submit a response for a held message, we would get a pop-up stating that “This form is insecure” , if we proceeded, the form submitted but nothing would happen…the message was not approved or discarded. After I removed the rewrite rule, the action works now, but it drops me onto the http:// site not https:// . Is there some site setting in Mailman I am missing to tell it to always use https:// ?

What can cause "Munge From" (from_is_list) to have no effect?
by Mark Hills June 19, 2022

June 19, 2022

I'm having trouble with a Mailman install which I maintain for a charity (2.1.39_1 on FreeBSD 12.3-p5) In diagnosing a DMARC "FAIL" reported in Gmail I notice that some settings are having absolutely no effect: from_is_list dmarc_moderation_action dmarc_quarantine_moderation_action dmarc_none_moderation_action So in my testing today, at no point have I been able to get Mailman to "Munge From" or "Wrap Message" in any way. Other nearby settings work, so I am able to change the config; it's the correct list etc. I've also tried re-starting. Logs in /usr/local/mailman/log aren't showing any errors or hints. As some feedback, an FAQ [*] mentions ALLOW_FROM_IS_LIST; setting this has no impact, not suprising as the source code doesn't seem to mention this string anyway. Reading more carefully, I can see this doesn't apply to the current version; perhaps someone with Wiki access might consider the manner it's written, whilst technically correct, is a little backward/confusing, or removing old information. [*] https://wiki.list.org/DOC/What%20can%20I%20do%20about%20members%20being%20u… Many thanks -- Mark
