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

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

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
by Ralf Hildebrandt 27 Jul '24

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

Digests not working correctly
by Joel Lord 08 Jun '24

08 Jun '24

So I seem to have problems with both periodic AND size-triggered digests. Size first, this is simpler. Just got one sent out, clearly triggered by a new email getting added to the queued up messages, but the setting for the list is the default 30KB and the digest came out at 23.2 KB. Is it measuring the accumulated queue as size on disk including metadata and filesystem block sizes or something, rather than the size of what the emailed digest will be? Periodic is much more complicated, even to explain. I have the cron job running nightly at 11:00 PM and it certainly seems to be working, except for one really odd thing. The list also definitely has periodic digests enabled in the web UI. This is a very bursty list, so it will go mad with traffic for a few weeks and then will go mostly idle for a month or so. The first digest of a burst is definitely size-triggered, but pretty reliably it has the last few messages from the previous burst in there. So the one I got today had three messages from today and one message from May 4th. But that May 4th message should have gone out at 11:00 PM on May 4th with the daily digest and then gotten flushed from the pending digest queue, right? -- Joel Lord

Trying to save a new style
by Perry Kollmorgen 07 Jun '24

07 Jun '24

Dear Mailman-users list, I have embarked on project to stand up a Mailman3 instance for general staff email announcements and a small number of adhoc lists. I have a fair amount up and working using Docker and Postfix, with generally emails to/from lists working well, as well as the web interface. One of the reasons I've used Mailman3 is the API and mailman shell options which I'm slowly trying to wrap my head around, but having some progress. I have a question for the moment on something which has stumped me, and whilst I may have more questions as I continue on this implementation, I am hopeful someone can point out where I am going wrong on this. Welcome to the GNU Mailman shell Use commit() to commit changes. Use abort() to discard changes since the last commit. Exit with ctrl+D does an implicit commit() but exit() does not. >>> from zope.component import getUtility >>> from mailman.interfaces.styles import IStyleManager >>> manager = getUtility(IStyleManager) >>> >>> for style in manager.styles: ... print(style.name) ... legacy-announce legacy-default private-default >>> >>> >>> from zope.interface import implementer >>> from mailman.interfaces.styles import IStyle >>> @implementer(IStyle) ... class TestStyle: ... name = 'AB-Announce-Style' ... description = 'AB Announce mailing list style.' ... def apply(self, mailing_list): ... mailing_list.admin_immed_notify = true ... mailing_list.admin_notify_mchanges = true ... mailing_list.advertised = false ... mailing_list.allow_list_posts = false ... mailing_list.anonymous_list = false ... mailing_list.archive_policy = "private" ... mailing_list.archive_rendering_mode = "markdown" ... mailing_list.collapse_alternatives = false ... mailing_list.convert_html_to_plaintext = false ... mailing_list.default_member_action = "defer" ... mailing_list.default_nonmember_action = "hold" ... mailing_list.digest_send_periodic = false ... mailing_list.digests_enabled = false ... mailing_list.emergency = false ... mailing_list.include_rfc2369_headers = true ... mailing_list.max_message_size = 40000 ... mailing_list.max_num_recipients = 30 ... mailing_list.member_roster_visibility = "moderators" ... mailing_list.send_goodbye_message = true ... mailing_list.send_welcome_message = true ... mailing_list.subscription_policy = "moderate" ... mailing_list.unsubscription_policy = "moderate" ... >>> manager.register(TestStyle()) >>> >>> commit() >>> >>> for style in manager.styles: ... print(style.name) ... AB-Announce-Style legacy-announce legacy-default private-default So at this point the style has been registered, however it doesn't look to save this permanently. When I quit the shell and log back in, it only shows the original 3 styles. Nor can I see the style from the web interface. Welcome to the GNU Mailman shell Use commit() to commit changes. Use abort() to discard changes since the last commit. Exit with ctrl+D does an implicit commit() but exit() does not. >>> from zope.component import getUtility >>> from mailman.interfaces.styles import IStyleManager >>> manager = getUtility(IStyleManager) >>> >>> for style in manager.styles: ... print(style.name) ... legacy-announce legacy-default private-default >>> Is there a way to save this style permanently ? Thank you for any assistance you can provide. Regards, PerryK
