Which folder should I share between pods with kubernetees persistentVolumeClaim ?
by antoine.depoisier＠ikmail.com Feb. 7, 2025

Feb. 7, 2025

I use mailman with kubernetees, and I have four pods. I currently use persistentVolumeClaim for two folders in the mailman configuration "cache" and "messages". I share these folders, as mailman needs to be consistent for these two folders, but I'm wondering if I should share other folders as well, like locks and such. There are all the folders in mailman archives cache data etc lists locks logs master.pid messages queue templates I ask this question because I often have a problem when creating a mailing list. I think I have a problem with the locks, but I'm not sure if the problem is due to the fact that the locks folder is not shared. If you want more details, here's the trace I sometimes get, when someone tries to create a mailing list: File "falcon/app.py", line 365, in falcon.app.App.__call__ File "/usr/lib/python3.12/site-packages/mailman/rest/lists.py", line 322, in on_post mlist = create_list(**validator(request)) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/usr/lib/python3.12/site-packages/mailman/app/lifecycle.py", line 102, in create_list call_name(config.mta.incoming).create(mlist) File "/usr/lib/python3.12/site-packages/mailman/mta/postfix.py", line 96, in create self.regenerate() File "/usr/lib/python3.12/site-packages/mailman/mta/postfix.py", line 106, in regenerate with Lock(lock_file): ^^^^^^^^^^^^^^^ File "/usr/lib/python3.12/site-packages/flufl/lock/_lockfile.py", line 467, in __exit__ self.unlock() File "/usr/lib/python3.12/site-packages/flufl/lock/_lockfile.py", line 417, in unlock raise NotLockedError('Already unlocked') flufl.lock._lockfile.NotLockedError: Already unlocked When I check the lock folder, I have these two files, and I'm wondering if I should delete these two files : -rw-rw---- 2 mailman nogroup 97 Feb 6 2025 master.lck -rw-rw---- 2 mailman nogroup 97 Feb 6 2025 master.lck|mailman-core-deployment-5f59557b66-bkkf4|16|4268829230172994873 Do you have any answer for me ?

Configuring ARC with multiple domains in Mailman3
by Lance A. Brown Feb. 6, 2025

Feb. 6, 2025

I'm working on setting up MailMan 3 on an Ubuntu 24.04 LTS server. I've got everything running and working with docker-mailman. Now I'm looking at configuring ARC and am a bit lost. How is ARC configured in a mailman3 with multiple domains? Do I set it up to use the hostname of the server Mailman is running on? Thanks for any assistance, --[Lance]

One-click unsubscribe?
by Jered Floyd Feb. 5, 2025

Feb. 5, 2025

I'm having a lot of problems with GMail delivery due to lack of "one-click unsubscribe" -- however that is quantified, which is not clear. In particular, there is an issue with the fact that Google ignores dots in email addresses. So I have many (MANY!) subscribers who try to use the List-Unsubscribe header target, but because they are subscribed as "idiotsubscriber(a)gmail.com" rather than "idiot.subscriber(a)gmail.com" (which they have since changed their sender to) they get a reject that they are not subscribed. These people are also far too unobservant to read the footer of every message that reads "You are subscribed as idiotsubscriber(a)gmail.com". Is there any way to provide personalized List-Unsubscribe header links, or have Mailman ignore dots in gmail.com addresses... or... anything? I'm finding reported spam percentages in the Google Postmaster Dashboard exceeding 0.1%, which causes massive delivery blocking to GMail-based subscribers. While I would gladly ban everyone who uses gmail, that sadly accounts for about half of the Internet today and would be incredibly unproductive. Thanks, --Jered

Moderation action "None" is misleading
by Markus Grandpré Feb. 5, 2025

Feb. 5, 2025

Dear List, I find the use of the term 'None' (or 'Kein' in the German translation; see attachments) in the 'Moderation action' column of the member list misleading, as the term suggests that no moderation action is applied to the respective member. However, this is not necessarily the case. If you check a member’s "Administration options / Moderation" setting, a moderation action, such as "Moderation" or "List default", may be in effect. I suggest that the 'Moderation action' column should display the currently set value of the 'Administration options / Moderation' setting for each member. Since some of our mailing lists frequently add and remove thousands of members, manually adjusting this setting for each member would not be practical.

The paradox of VERP probe messages
by Jeremy Stanley Feb. 2, 2025

Feb. 2, 2025

tl;dr: Is there a way to have VERP probe messages not include copies of the bounce message that triggered them? Longer form... Some months ago I turned on bounce processing for a fairly large list with a long history, because I could see from the MTA logs that there were easily hundreds of old subscribers whose addresses had become defunct and this seemed like a great way to clean that up and make the server more conscientious at not repeatedly trying to deliver messages to sites that were just going to reject them. This worked really well. Until legitimate subscribers also started to get removed, that is, due primarily to false positives from overzealous spam filters. I had previously read about MM3's VERP probe message feature, which seemed to solve the main reason I had kept bounce processing disabled in the MM2 days, and thought it was on by default but clearly it wasn't. So I found the necessary config option and switched that on. This worked really well. Until legitimate subscribers started to get removed again, that is, due primarily to false positives from overzealous spam filters. See, I realized that the VERP probes were helpfully including copies of the most recent bounce for that user, and those NDRs quite often helpfully included their own copies of the messages which had been bounced. So if a subscriber's MTA was rejecting a message because the content looked like spam, then there was a good chance it would also reject the VERP probe message because it included the same content which had caused the earlier rejection. The VERP probe feature was essentially defeating its own purpose as a neutral confirmation that the subscriber hadn't been rejecting messages due to their content. This behavior raises a more significant concern as well. The MTA on the Mailman server in this case (Exim if it matters) wants to perform batch deliveries when there are multiple subscribers who all share the same remote MTAs. If multiples of those reject a list post, then the NDR back to Mailman aggregates those multiple rejections into a single message. If that incident triggers a VERP probe, the bulk NDR enumerating the addresses of all the subscribers who were rejected gets forwarded along as part of the VERP probe, disclosing a potentially sensitive litany of random subscriber addresses to other subscribers within that batch. I don't know whether this is a misconfiguration, or an unintended consequence of the intersection of Mailman and MTA features. While I understand that the inclusion of a bounce sample within a VERP probe may be a way to take some workload off list admins in that users can possibly see a message/rejection to explain the reason for the probe, the downsides of that choice make the feature unfortunately unusable for some lists that could otherwise have benefited from it. Am I possibly missing an existing switch that could make VERP probe messages *not* include copies of the bounces that triggered them? This is in some ways similar to the problems I've noticed with message hold notifications to moderators including copies of the held messages, since these are (at least in the case of the lists I manage) often spam, so has a tendency to cause the mail providers for the list moderators to start considering the mailing list server a spam source. If there were a switch to make message hold notifications to moderators *not* include copies of the messages themselves, I'd start allowing moderator notifications again. Suggestions welcome! Also willing to try to submit patches to enable some of these solutions if they don't already exist. And thanks to anyone who read this far! -- Jeremy Stanley

Outgoing runner lockup? + "slice inspector" tool
by Stephen J. Turnbull Feb. 1, 2025

Feb. 1, 2025

Hi, I'm advising a user on a system which experiences occasional lockups in an outgoing runner. The runner contacts a remote smarthost, and occasionally locks up with the smtp connection still open according to "lsof -i :25". This state seems to be permanent: the backlog for that slice starts to grow without bound, for at least an hour. When this was happening once a month, they would just restart Mailman core, and the backlog would clear in minutes. But recently it's been happening daily which is distracting their staff, and worries me. Another thing that is strange about this site is that it should be possible to hit that runner with a SIGUSR1 and restart it. This works for me, but on that system the stuck runner exits, but does not restart. Since normally it only happens to one runner of several, I wanted to identify the runner and process. I attach the tool I developed, for anyone who might have configured multiple runners and is interested to see the distribution across runners. Has anybody seen an outgoing runner lock up with an open smtp session? Any ideas on why? My analysis so far: - Because a restart works every time, I'm pretty sure it doesn't have anything to do with message content. - I believe both the Mailman host and the outgoing smarthost are Linodes, in the same datacenter. The problematic Mailman system is Mailman 3.3.6, Python 3.10 on Ubuntu 16.xx LTS. I believe the smarthost is a more recent Ubuntu LTS, probably running Postfix 3.7 as the MTA. (Yes, they have sufficiently paranoid security and QA teams. ;-) - We're using smtplib, which as far as I can tell basically has a 60s timeout for each command. Thus you'd think it would time out. I guess it could be inflooping on timeout, retry, timeout, retry, but I don't know how to check that. Maybe ss(8) will serve? - My system where SIGUSR1 works as documented is Python 3.11.2 on a Digital Ocean droplet with Debian 12.9, Linux 6.1.0. - I haven't tried to reproduce the Python 3.10 + Mailman 3.3.6 configuration and test SIGUSR1 in that configuration yet. Seems unlikely, waiting for the proverbial "round tuit". - It has occurred to us to use the local Postfix as the relay MTA. I'm waiting on a report whether that alleviates the problem. Even if so, I want to fix the underlying defect if possible. Any ideas would be welcome, including general debugging advice. Here's the promised slice_inspector tool. (Patches and suggestions welcome, though I don't promise to implement any time soon.) The tool imports some files from Mailman core, click, and psutil (not psutils!) I believe the latter modules are required by Mailman, so you should be able to run it as is under the 'mailman' user (or perhaps 'list' on Debian) in the environment Mailman itself uses. It defaults to assuming that mailman.cfg is /etc/mailman3/mailman.cfg. You'll probably need to fix the shebang if you want to chmod +x. The '--help' should be pretty self-explanatory. Steve

messages with attachments, without text discarded silently
by Schulz Feb. 1, 2025

Feb. 1, 2025

Using the current mailman version, I can reproduce the following: - send a text-formatted email with attachment but without text body to a list. - the msg will be received by mailman - the msg shows up in shunt, the log shows: ile "/usr/lib/python3.12/email/message.py", line 343, in set_payload payload = payload.encode(charset.output_charset, 'surrogateescape') ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ UnicodeEncodeError: 'ascii' codec can't encode characters in position 10-17: ordinal not in range(128) an attempt to unpickle the file leads to the same error. I know it's uncommon to send emails without txt but with attachments - but it may happen; at least we would welcome an error message.

Occasionally "The content of this message was lost."
by Frank Richter Jan. 30, 2025

Jan. 30, 2025

Hello, occasionally we face the problem "The content of this message was lost." when handling a message on hold. We use the mailman3 packages on Debian 12: 3.3.8-2~deb12u2 GNU Mailman 3.3.8 (Tom Sawyer) Python 3.11.2 (main, Nov 30 2024, 21:22:50) [GCC 12.2.0] with postgresql, exim and Apache httpd on the same machine.

I have tried to find an equal issue, but could not find it. If so, sorry for the doubling... I have recently setup a fresh mailman3 installation on my debian12 box. It works fine. The only thing which is not working is in the archive overview I see a spinning wheel. The participants and number of discussions is increasing and the archive files are getting the archived messages. mailman -info shows: GNU Mailman 3.3.8 (Tom Sawyer) Python 3.11.2 (main, Nov 30 2024, 21:22:50) [GCC 12.2.0] config file: /etc/mailman3/mailman.cfg db url: mysql+pymysql://.....:....@localhost/mailman3?charset=utf8mb4&use_unicode=1 devmode: DISABLED REST root url: http://localhost:8001/3.1/ REST credentials: restadmin:....... mailman-web qinfo shows: -- Default 1.3.9 on ORM default -- Clusters 0 Workers 0 Restarts 0 Queued 0 Successes 100 Failures 0 Schedules 0 Tasks/day 14.00 Avg time 0.1756 Webserver: apache2/2.4.64 It looks like a AJAX problem, but not sure about that. Any help would be appriciated. Freerk What is missing
