Does Mailman 3 log subscribes and unsubscribes for each list the way Mailman 2 did? Brian

Questions regarding message acceptance
by Pawel Grzywaczewski 19 Sep '24

19 Sep '24

Hello, I have few questions regarding usage of Mailman3: 1) We have list1 and list2 with members. Can we specify that all members of list1 can post messages to list2? We could potentially write a script that would synchronize members of another list to “Accept these non-members” of another list, but with thousands of lists it will be difficult to maintain lists in synchro. So perhaps there is a concept of adding another list to “Accept these non-members” and mailman real-time evaluate membership of another list upon message arrival? 2) In explanation of “Accept these non-members” it’s written: “While non-regexp addresses can be entered here, it is preferred to add the address as a nonmember and set the nonmember's Moderation to Default Processing”. I noticed that if someone posts to a list then he is added automatically to non-members. Which means that next time he will be able to post. My understanding is that it’s better to use the feature “Accept these non-members”. Am I correct? Thank you, Paweł

Disabled by bounce
by Allan Hansen 11 Sep '24

11 Sep '24

Hi all, Apparently Google just started to get very aggressive about DKIM settings. Some hundreds of my subscribers have had their subscriptions disabled because of Google's bounces. I tried to 'Enable' some of them, expecting that their bounce scores would be reset, but when I list the users, the bounce scores are still 5. Please advise. Will enabling them without the bounce score being reset just cause the server to disable them again. Yours, Allan

How to remove Held Unsubscriptions
by Mark 10 Sep '24

10 Sep '24

Hi As a moderator I receive an email each day for "Held Unsubscriptions" for a subscriber that was unsubscribed by the Owner sometime ago (using "Mass operations"). +++++++++++++++++++++++++++++++ The listname(a)domain.com list has 1 moderation requests waiting. Held Unsubscriptions: User: bart(a)example.com Please attend to this at your earliest convenience. +++++++++++++++++++++++++++++++ There is nothing showing under "Subscription requests > Pending approval". Could anyone tell me how I can stop these email notifications? I have access to the mailman shell and the databases. Thanks, Mark

security app causing django Internal Server Error: /archives/search emails
by sun zi 05 Sep '24

05 Sep '24

Greetings, I have set up a few lists and all seems to be working as expected, however I get a large number of emails due to internal server errors received when my security application is testing exploits to list URLs such as the following: https://<mylistdomain>/archives/search?sort=177120&cauft=&page=1&q=../../../../../../../../../../tmb/wditeteet424465304.txt. Is there any django logging filter changes that can be made to avoid receiving these emails? Any assistance would be greatly appreciated. Thank you!

Does Mailman 3 have something similar to https://www.msapiro.net/scripts/last_post.py displaying the last post time for a list or all lists?

MM3 generates long lines?
by peter＠chubb.wattle.id.au 28 Jul '24

28 Jul '24

I'm seeing emails being dropped when mm3 talks to the local smtp server, with log errors like: 2021-06-23 15:42:24 1lvvea-007r8u-VN H=localhost (<FQDN>) [::1] F=<announce-bounces@<FQDN>> rejected after DATA: maximum allowed line length is 998 octets, got 1036 The email itself did not have such long lines AFAICT. I can disable line length checking on the mailserver, but that sounds like a recipe for the next one along to drop the email. Peter C

Issues with a DMARC record leading to message being shunted

27 Jul '24

Hi! Recently a mail was not being distributed via our MM3 instance; I searched the logs and found: Dec 22 04:54:27 2023 (24) ACCEPT: <1d431542-b386-467b-8bf2-305f19ee7eb4(a)somenet.org> Dec 22 04:54:28 2023 (28) Uncaught runner exception: list index out of range Dec 22 04:54:28 2023 (28) Traceback (most recent call last): File "/usr/lib/python3.10/site-packages/mailman/core/runner.py", line 179, in _one_iteration self._process_one_file(msg, msgdata) File "/usr/lib/python3.10/site-packages/mailman/core/runner.py", line 272, in _process_one_file keepqueued = self._dispose(mlist, msg, msgdata) File "/usr/lib/python3.10/site-packages/mailman/runners/pipeline.py", line 37, in _dispose process(mlist, msg, msgdata, pipeline) File "/usr/lib/python3.10/site-packages/mailman/core/pipelines.py", line 53, in process handler.process(mlist, msg, msgdata) File "/usr/lib/python3.10/site-packages/mailman/handlers/validate_authenticity.py", line 125, in process authenticate(msg, msgdata) File "/usr/lib/python3.10/site-packages/mailman/utilities/retry.py", line 44, in f_retry return f(*args, **kwargs) File "/usr/lib/python3.10/site-packages/mailman/handlers/validate_authenticity.py", line 93, in authenticate auth_result = authenticate_message( File "/usr/lib/python3.10/site-packages/authheaders/__init__.py", line 395, in authenticate_message dmarc_result = check_dmarc(msg, spf_result, dkim_result, dnsfunc=dnsfunc, psddmarc=psddmarc) File "/usr/lib/python3.10/site-packages/authheaders/__init__.py", line 343, in check_dmarc result, result_comment, from_domain, policy = dmarc_per_from(from_domain, spf_result, dkim_result, dnsfunc, psddmarc) File "/usr/lib/python3.10/site-packages/authheaders/__init__.py", line 90, in dmarc_per_from record, orgdomain = receiver_record(from_domain) File "/usr/lib/python3.10/site-packages/authheaders/dmarc_lookup.py", line 117, in receiver_record retval = lookup_receiver_record(hostSansDmarc, dnsfunc) File "/usr/lib/python3.10/site-packages/authheaders/dmarc_lookup.py", line 92, in lookup_receiver_record tags = answer_to_dict(str(result)) File "/usr/lib/python3.10/site-packages/authheaders/dmarc_lookup.py", line 42, in answer_to_dict retval = {t[0].strip().lower(): t[1].strip().lower() for t in rawTags} File "/usr/lib/python3.10/site-packages/authheaders/dmarc_lookup.py", line 42, in <dictcomp> retval = {t[0].strip().lower(): t[1].strip().lower() for t in rawTags} IndexError: list index out of range Dec 22 04:54:28 2023 (28) SHUNTING: 1703220868.1418982+b27f5db154375fcd2c418d467172e4aad0d3d57a So the message has been shunted, due to this error. Something with DMARC and tags. So I checked the DMARC record for the sending domain somenet.org. It is "v=DMARC1;p=none;pct=100;rua=mailto:postmaster@somenet.org;mailto:postmaster@somenet.org;ri=3600;fo=1;" which is syntactically incorrect. The extra ";mailto:postmaster@somenet.org" is wrong, I guess the tag "ruf=" is missing here! It should probably read "v=DMARC1;p=none;pct=100;rua=mailto:postmaster@somenet.org;ruf=mailto:postmaster@somenet.org;ri=3600;fo=1;" So, should mm3 somehow "catch" this error somehow? According to the DMARC specs, an syntactically incorrect DMARC record should be ignored / handled as if none were present. -- Ralf Hildebrandt Charité - Universitätsmedizin Berlin Geschäftsbereich IT | Abteilung Netz | Netzwerk-Administration Invalidenstraße 120/121 | D-10115 Berlin Tel. +49 30 450 570 155 ralf.hildebrandt(a)charite.de https://www.charite.de

Held messages showing a reason not in English on the Postorious
by Alan KT So (ITSC) 27 Jun '24

27 Jun '24

We just notice a held message from a user's list showing the held reason in Ukrainian, but the interface is in US English and the list's preferred language is English (USA). We could not repeat the issue. What can be the reason behind?
