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.

sudden (?) issue with subscription options CGI
by ddewey＠cyberthugs.com Dec. 1, 2024

Dec. 1, 2024

Have an older RHEL 7 Mailman2 server that's worked flawlessly for years, but whose time is short... new MM3 server slowly being built. However, one of my members alerted me today that they were unable to log into the Subscription Options page due to a 500 Server Error. The page itself displays fine, but entering the username and pass results in the server error. Only thing I see in the apache error logs is as follows (listdomain and list name obfuscated): End of script output before headers: options, referer: https://list.listdomain.com/mailman/options/listname As far as I know (dangerous), this was working fine post-last upgrade, which was September '23, and everything else is working fine other than the Options cgi. Running mailman-2.1.39 installed from source. Minimal config options on build - ./configure --with-cgi-gid=apache Apache httpd-2.4.6-99.el7_9.1 Python 2.7.5 Any other hints to try to debug this? Didn't see anything at all in any of the Mailman logs. Thanks for any suggestions!

Unexpected error with senddigests
by Mailman Admin Nov. 25, 2024

Nov. 25, 2024

Hello We are still on Mailman 2 (preparing for switch to Mailman 3). Our current production system works since more than 15 years without hiccups. We have suddenly an error with senddigests. # /usr/lib/mailman/cron/senddigests -l MAILINGLIST List: MAILINGLIST: problem processing /var/lib/mailman/lists/MAILINGLIST/digest.mbox: This error only occurs with one mailing list. We could not find any additional error messages. No digest is sent for this list. We checked access rights, they are OK. The content of /var/lib/mailman/lists/MAILINGLIST/digest.mbox seems to be OK too. Any idea, why this could happen? Or how we can get more error infos? System: Debian GNU/Linux 10 (buster) ELTS Python 2.7.16 mailman 2.1.29-1+deb10u5 Kind regards, Christian Mack -- Christian Mack Universität Konstanz Kommunikations-, Informations-, Medienzentrum (KIM) Abteilung IT-Dienste Forschung, Lehre, Infrastruktur 78457 Konstanz +49 7531 88-4416

Read-only File System
by John Nov. 20, 2024

Nov. 20, 2024

Hello, Several days ago, I posted a message to his list concerning our installation of Mailman 2, and a weird problem that caused messages posted to a list to fail, as /usr/local/mailman/qfiles/in/ was behaving like it was read-only. First off, thanks to everyone who replied with suggestions. While we haven't determined what was causing this issue, we did devise a work-around of sorts. I'm posting it here in case someone else encounters the same issue. The problem that we encountered was that mailman / python regarded /usr/local/mailman/qfiles and all the directories under it to be read-only. They're not - anything else that wants to create a file therein can do so. This was how we fixed it: 1. Stop mailman if it's running. 2. cd /usr/local/mailman . 3. cp -R qfiles /qfiles . (I suspect there are more appropriate places to copy the directory to, such as /var - this worked for us and we stopped messing with it.) 4. mv qfiles qfiles.dist - just in case you ever figure out the real cause and want to reverse all this. 5. ln -s /qfiles qfiles . (That is, create a symbolic link to the /qfiles directory, or wherever you decided to put it.) 6. Start mailman Mailman proved to have no problem writing to the relocated qfiles directory, and everything magically started working. Hope this saves someone from banging their head against a wall, as we very nearly wound up doing. ::Jack

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

Reliable mailing list deliveries
by Hoover Chan Nov. 4, 2024

Nov. 4, 2024

I'm looking for current best practices for configuring Mailman servers so that they can deliver mail to subscribers, especially those with gmail addresses and other e-mail service providers who use similar anti-spam strategies. Is it simply some combination of SPF, DMARC and DKIM? Maybe a particular way to set these up? Or something else? (The MTA? DNS?)
