Editing Mailman's text files
by Pete Bell 08 May '24

08 May '24

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 27 Feb '24

27 Feb '24

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?

spamming
by Jim Dory 17 Dec '23

17 Dec '23

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

Unable to post messages to a Mailman 2 List
by Francis Jayakanth 07 Dec '23

07 Dec '23

Hi, I'm administering and moderating a professional list called LIS-Forum with close to 5k members. I'm still on Mailman 2.1.26 on Ubuntu 18.04 with Postfix as an MTA. Till recently, the list was running smoothly. On average, there will be 2/3 postings every day. However, postings have not been received in the last two days. When I explored further, I noticed that postings made to the list are not reaching the list, nor are the members posting messages getting acknowledgements. I'm using SMTP Office 365 as the relay host. Generic emails sent from the Mailman server are getting distributed. So, there aren't any issues with incoming or outgoing emails. Mailman as service is up and running, and its service status is as follows: #service mailman status â mailman.service - Mailman Master Queue Runner Loaded: loaded (/lib/systemd/system/mailman.service; enabled; vendor preset: enabled) Active: active (running) since Thu 2023-11-16 14:11:31 IST; 30min ago Process: 2586 ExecStop=/usr/lib/mailman/bin/mailmanctl stop (code=exited, status=0/SUCCESS) Process: 2616 ExecStart=/usr/lib/mailman/bin/mailmanctl -s start (code=exited, status=0/SUCCESS) Main PID: 2617 (mailmanctl) Tasks: 9 (limit: 4915) CGroup: /system.slice/mailman.service ââ2617 /usr/bin/python /usr/lib/mailman/bin/mailmanctl -s start ââ2619 /usr/bin/python /var/lib/mailman/bin/qrunner --runner=ArchRunner:0:1 -s ââ2620 /usr/bin/python /var/lib/mailman/bin/qrunner --runner=BounceRunner:0:1 -s ââ2621 /usr/bin/python /var/lib/mailman/bin/qrunner --runner=CommandRunner:0:1 -s ââ2622 /usr/bin/python /var/lib/mailman/bin/qrunner --runner=IncomingRunner:0:1 -s ââ2623 /usr/bin/python /var/lib/mailman/bin/qrunner --runner=NewsRunner:0:1 -s ââ2624 /usr/bin/python /var/lib/mailman/bin/qrunner --runner=OutgoingRunner:0:1 -s ââ2625 /usr/bin/python /var/lib/mailman/bin/qrunner --runner=VirginRunner:0:1 -s ââ2626 /usr/bin/python /var/lib/mailman/bin/qrunner --runner=RetryRunner:0:1 -s Nov 16 14:11:31 xxx.xxx.xxx.xx systemd[1]: Starting Mailman Master Queue Runner...

Intermittent attacks agains Mailman instance
by Rich Kulawiec 30 Nov '23

30 Nov '23

Over the past couple of months, I've observed a series of attacks against Mailman that are likely related because they use the same tactic every time. That tactic is to use Mailman's web interface to generate multiple subscription requests for multiple people. My guess is that the goal may be either (a) to harrass those people or (b) to get the outbound subscription confirmation requests from Mailman marked as spam (in mail systems which support that function) or (c) both. To spot this: check your subscription logs for bursts of activity -- in particular, subscription requests for the same address to multiple lists (including multiple unrelated mailing lists), and in further particular, requests that are never ACK'd, AND, in further particular, requests that originate from network space unlikely to be populated by real users. Of course I have no way of knowing if the instance I'm looking at is the only one being targeted or whether others are seeing this as well. On that point, it might be useful for those of you reading this to extract the networks below and use "grepcidr" or a similar tool to check them against your logs. That's part of my reason for writing this. The other part is to share the lists of network allocations that I've firewalled out from ports 80 and 443; all of these participated in one or more attacks (and subsequently tried to particpate in others, but were blocked). You may want to preemptively drop these into your firewall(s) IF it turns out that other Mailman instances are also being targeted. Here there are, in three groups: Pnvgroup: 23.94.58.0/25 PNVGROUPLtd 23.94.58.128/25 PNVGROUPLtd 23.95.99.0/25 PNVGROUPLtd 107.172.18.0/25 PNVGROUPLtd 192.3.56.0/25 PNVGROUPLtd 192.3.56.128/25 PNVGROUPLtd 192.3.57.0/25 PNVGROUPLtd 192.3.57.128/25 PNVGROUPLtd 192.3.58.0/25 PNVGROUPLtd 192.3.58.128/25 PNVGROUPLtd 192.3.59.0/25 PNVGROUPLtd 198.12.72.128/25 PNVGROUPLtd 198.23.168.0/25 PNVGROUPLtd 198.23.168.128/25 PNVGROUPLtd 198.23.169.0/25 PNVGROUPLtd 198.23.170.0/25 PNVGROUPLtd 198.23.170.128/25 PNVGROUPLtd 198.23.171.0/25 PNVGROUPLtd 199.188.102.0/25 PNVGROUPLtd Proxies-LLC: 108.165.184.0/22 PROXIES-LLC 108.165.188.0/22 PROXIES-LLC 108.165.184.0/22 PROXIES-LLC 75.102.24.0/23 PROXIES-LLC 75.102.8.0/23 PROXIES-LLC Miscellaneous: 91.243.92.0/24 QualityNetworkCorp 91.243.94.0/24 QualityNetworkCorp 103.160.101.0/24 IRT-DURABLEDNS-AP 172.98.181.0/24 Braveway/PrivateCustomer 172.104.17.0/24 Linode (this is just a chunk of the network) 194.26.135.0/24 ChangWayTechnologiesCoLimited 194.33.191.0/25 VirtuoHoldingsInc 194.33.191.128/25 VirtuoHoldingsInc ---rsk

Mailman 3 Issue - Unable to Authenticate with Mailman Core REST API
by Patricia Traore 27 Nov '23

27 Nov '23

Fellow mailman enthusiasts, I am configuring Mailman 3's web frontend components, Hyperkitty, based on the provided documentation: <https://docs.mailman3.org/en/latest/config-web.html>. I have successfully set up Django and completed various configuration steps, but I am encountering an issue with authenticating with the Mailman Core REST API. Description of the issue: → Mailman core REST API Configuration: in the Django settings.py file, I have set the MAILMAN_REST_API_URL to the correct URL of the Core's REST API server (http://localhost:8001/). Additionally, I have specified the MAILMAN_REST_API_USER and MAILMAN_REST_API_PASS with the appropriate credentials (default values used in the core are 'restadmin' and 'restpass'). → Authentication failure: despite the correct configuration of the REST API settings, when attempting to interact with the Mailman Core REST API through Hyperkitty, authentication fails. Depicting that authentication credentials are invalid. → MAILMAN_ARCHIVER_KEY configuration: I have also configured the MAILMAN_ARCHIVER_KEY in the Django settings.py file, ensuring that it matches the value set in the mailman-hyperkitty.cfg file as per the documentation. → Documentation: I have carefully followed the documentation related to the Mailman REST API and the configuration parameters. However, I couldn't find any specific troubleshooting steps or additional settings that might be required to ensure successful authentication. That's why I'm here seeking assistance to identify any potential misconfigurations or steps I might have missed in setting up the authentication between the Mailman web components and the Mailman Core REST API. Your insights, suggestions, or guidance on resolving this authentication issue would be highly appreciated. Let me know if additional information or specific configurations are needed. Thanks in advance for your support! Patricia T. Flexing codes with <https://maniflexa.com/services/uganda-web-design-company/>.

Excessive or fatal bounces issue
by Florin Pasăre 23 Nov '23

23 Nov '23

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,

Sharing PHP or Scripts to a list
by patricia traore 22 Nov '23

22 Nov '23

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
