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

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

Installing Mailman on Ubuntu
by Dennis Putnam July 20, 2024

July 20, 2024

I'm trying to install mailman 3 on Ubuntu. It seems that mailman is not in any of the Ubuntu repositories. If there is a repo, I can't find it. Instead I cloned the github source. However, there is no documentation, that I can find, that explains what to do with the source (https://docs.mailman3.org/projects/mailman/en/latest/src/mailman/docs/insta…). Can someone point me to a repo for Ubuntu or documentation on how to compile and install mailman 3 from source?

Error messages from Mailman without "real content".
by Christian Buser July 20, 2024

July 20, 2024

Hi all We are running some lists using Mailman (obviously version 2.1.39) on cPanel (110.0.36). For some days now, I have received 2 or 3 error messages which are not telling me anything, see the "Errormessage.jpg" attached. Sorry, my error message is in German, but I’ll quickly try to translate: "A message to the list was notdistributed and needs approval by you as an administrator". But I see nothing in the error message about the reason why it is held. I see the originally sent message to the list as an attachment, and I also see the "confirm" message, which I could use to discard the message. Using confirm message works, but if I try to discard the message from cPanel’s mailing list interface (open moderator’s actions, or how it could be called in English), I get an error - see "HitaBug.jpg" attached. Our provider says he has no idea how to correct this behaviour (which is new for me, it worked until probably a weeg ago). Thank you for any ideas.

Hackers subscribing lots of people
by John July 18, 2024

July 18, 2024

Hello, We're running mailman 2. Quite a few script kiddies and other idiots have figured out that they can use our mailman installation to annoy people. They bypass the subscribe page directly, and run cgi-bin/subscribe directly - many, many times. We fixed the problem by removing the appropriate executable permission from cgi-bin/subscribe and rewriting the list info page to handle subscriptions differently. (We removed the Subscribe fields and button.) While this works, it's inelegant and a bit convoluted. Is there another way to prevent this, and leave the default info page intact? Thanks. ::Jack

Mailman subscribe confirmation
by John July 5, 2024

July 5, 2024

Hello, We've encountered a weird issue with mailman 2. We're using mailman 2.1.39, running on a straight RHEL 9 server. When someone subscribes to a mailing list, they receive an email that says, among other things: Or visit this web page: http://<ourdomain.com>/mailman/confirm/<ourlist>/9e2fccef2ac047bb3d67e602e7fb695a277afe43<http://ourdomain.com/mailman/confirm/ourlist/9e2fccef2ac047bb3d67e602e7fb69…> Normally, clicking on this link would confirm the subscription. In our case, it prompts for the string again, and keeps doing so - it seems that mailman doesn't recognize the string as being valid. Using one of the other confirmation methods, such as just replying to the message, works correctly. The new subscriber is confirmed successfully. The same issue occurs for unsubscribe requests. The What steps are required for subscription? option is set to Confirm. Can anyone suggest how to fix this? Thanks. ::Jack

'mount' will show that, and fstab could make that the default. What happens when you manually try to create a file in /usr/local/mailman/qfiles/in/? Is 'selinux' turned on? that can cause all kinds of permission errors. How was mailman started and by which user? Are the mailman user/group correct? Otherwise, without a lot more info about your installation and whay you've checked we're just making wild guesses. z!

Read-only file system
by John July 1, 2024

We're attempting to install mailman on our new server. It's been running happily on our old one for years. This server is running Oracle 9 RHEL Linux. It uses postfix for its MTA. We built mailman 2. 1.39 from source, with the options ./configure --with-cgi-gid=apache –with-mail-gid=nobody . If someone subscribes to our mailing list, mailman will successfully send a confirmation message. Messages posted to the list, however, fail with: Command died with status 1: "/usr/local/mailman/mail/mailman post newsletter". Command output: Traceback (most recent call last): File "/usr/local/mailman/scripts/post", line 69, in <module> main() File "/usr/local/mailman/scripts/post", line 64, in main tolist=1, _plaintext=1) File "/usr/local/mailman/Mailman/Queue/Switchboard.py", line 136, in enqueue fp = open(tmpfile, 'w') IOError: [Errno 30] Read-only file system: '/usr/local/mailman/qfiles/in/1719765141.057583+cb104828efdd0023821ead337d3d60f72e949690.pck.tmp' Setting /usr/local/mailman/qfiles/in/ to have write permissions for all didn’t fix the problem. Does anyone have any experience with this issue, and a suggestion as to how to resolve it? We’ve tried everything we can think of, and madness is setting in. Thanks.
