Mailman sends Welcome emails, but does not send [List] postings emails

Having recently installed this same version of mailman (GNU Mailman 3.3.8 (Tom Sawyer)) a few times successfully, I have a puzzle with a current new installation. Via the command line I can create lists and add members, and the new members receive their Welcome message from mailman. But when a member sends an email to post to a list (e.g. hc(a)cs.org as shown here), the mailserver delivers it to mailman: May 29 16:36:58 localhost postfix/lmtp[44386]: E762E427CB: to=<hc(a)cs.org>, relay=127.0.0.1[127.0.0.1]:8024, delay=0.84, delays=0.8/0/0.01/0.03, dsn=2.0.0, status=sent (250 Ok) but no copy is sent to the members / subscribers. After the posts are received by mailman (as recorded in /var/tmp/mailman/logs/smtp.log), nothing more is added in any of the log files in /var/tmp/mailman/logs/... An attempt to imitate a technique seen elsewhere for [logging.smtp] for leaving some breadcrumbs by adding into mailman.cfg: - - - [logging.subscribe] level: debug path: mailman.log - - - and restarting mailman led to no detectable change. Expecting no change, I even changed for one UNmoderated list: >>> dump_json('http://localhost:8001/3.1/lists/hc.cs.org' ... '/config/default_member_action', ... dict(default_member_action='accept'), 'PATCH', ... username='...', password='...') date: Mon, 29 May 2023 16:31:31 GMT server: gunicorn status: 204 the default_member_action from 'defer' to 'accept' to rule out some moderation process delay. How can I enable some kind of trace or gather more information to learn where this configuration is in error? Cheers, Nelson

Migration failure (2.1.29 to 3.3.8 on Debian testing)
by {16/7} 08 Jun '23

08 Jun '23

Hello, I have both the mailman and mailman3-full packages installed on my machine and I'm following the migration guide located here: https://docs.mailman3.org/en/latest/migration.html Running the command { mailman import21 mylist(a)mysite.com /var/lib/mailman/lists/mylist/config.pck } completes once I create the list but states that it cannot convert the msg_footer and digest_footer mailing list attributes. (I might also point out that the { mailman create mylist(a)mysite.com } command isn't actually documented on that webpage.) I can't seem to find the manage.py script in my $PATH and after searching, I find it as part of the mailman3-web package. When I run { sudo -H -u list python manage.py hyperkitty_import mylist(a)mysite.com /var/lib/mailman/archives/private/mylist.mbox/mylist.mbox }, it fails with "ImportError: No module named django.core.management". If I run the script directly as { sudo -H -u list /usr/share/mailman3-web/manage.py ... }, I get "PermissionError: [Errno 13] Permission denied: '/usr/share/mailman3-web/settings_local.py'". By default, settings_local.py's group is www-data, and not knowing where to go next, I decided to try changing that file's group to list. When I re-ran the command (as user list), I got a Python traceback that gives "PermissionError: [Errno 13] Permission denied: '/var/log/mailman3/web/mailman-web.log'". Next, I changed the file's group back to list and decided to try running the manage.py script as the www-data user. This results in "/usr/lib/python3/dist-packages/django_q/conf.py:139: UserWarning: Retry and timeout are misconfigured." and "System check identified some issues:" followed by a list of "Auto-created primary key used when not defining a primary key type, by default 'django.db.models.AutoField'" warnings for a number of Django tables. At the end of this list is "CommandError: The list address must be given on the command-line". But it *was* given. My questions are: 1. How do I undo any damage (if any) my efforts may have caused? 2. What's the correct way to run manage.py?

Where does sender postorius@ come from?
by Jens Günther 07 Jun '23

07 Jun '23

I just realized, that mails for registering an account and/or resetting ones password are obviously sent from postorius@SERVE_FROM_DOMAIN. Why are they not sent from MAILMAN_ADMIN_EMAIL? The problem is: - an account is trying to register with a mailaddress from a HostEurope-server - HostEurope-Servers are doing Sender-Callouts (bad practise :-D) to verify that a mailaccount exists - mail is then bouncing, b/c those are not answered (shoud I?): status=bounced (host [80.237.138.5] said: 550-Sender verification is required but failed. - bounce then can't be processed, since mailaccount does not exist :-D status=bounced (mail for SERVE_FROM_DOMAIN loops back to myself) Am I missing something are shouldn't it be better to send those mails from MAILMAN_ADMIN_EMAIL? (I don't want to mess with these sender callouts or change anything, HostEurope has been a little bit of a pain in the ... with mailinglists and not much help at all). Thanks in advance, Jens.

Is there any way to tell which moderator of a list approved a particular post to that list?

Subscribe to a list on a Mailman3 server without account registration
by c.buhtz＠posteo.jp 06 Jun '23

06 Jun '23

Hello, I might miss something here but I'm confused about a difference between Mailman2 and 3. On MM2 I just subscribed a mailinglist via my EMail address. I didn't need to create an account on the MM2 server first. But it seems on MM3 it is otherwise. For example I use MM3 on python.org. It seems I have to register first before subscribing to a mailing list. https://mail.python.org/mailman3/lists/twisted-web.python.org/ Is this observation correct? Kind Christian

mailman break DKIM signature by modifying body
by Peter Münster 06 Jun '23

06 Jun '23

Hi, I'm using mailman 3.3.8. Some messages with attachments from Google users get rejected by spam filters because of invalid DKIM signatures. It seems, that mailman alters some lines in the body. Here an example: Original message: --8<---------------cut here---------------start------------->8--- Lines: 2031 --000000000000f846c505fc494b7a-- --000000000000f846c705fc494b7c Content-Type: application/pdf; [...] Content-Disposition: attachment; [...] --8<---------------cut here---------------end--------------->8--- Altered message: --8<---------------cut here---------------start------------->8--- Lines: 2032 --000000000000f846c505fc494b7a-- --000000000000f846c705fc494b7c Content-Type: application/pdf; [...] Content-Disposition: attachment; [...] --8<---------------cut here---------------end--------------->8--- An empty line is added, and the spaces after the semicolons are removed. Perhaps related to https://gitlab.com/mailman/mailman/-/issues/1079. What could I do please, to prevent such modifications of the body? TIA for any help, -- Peter

Digests not working correctly
by Joel Lord 05 Jun '23

05 Jun '23

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

Change config to create a new list with all archives off
by Tibor Molnar 02 Jun '23

Can archiving be changed anywhere in mailman3 configs, so then all new lists created do not archive by default?

Why are "Subscription options" left unselected if I don't manually select them?
by mrl＠psfc.mit.edu 01 Jun '23

01 Jun '23

When I subscribe to a mailing list, and I don't manually select some of the "Subscription options", they are left unselected when I go back to look at them. I would have thought that if I didn't make a selection, that they would be set to a default option. Or am I wrong? Thanks.

dmarc mitigation debug
by Thomas Krichel 01 Jun '23

01 Jun '23

Hi gang! I have a list with DMARC mitigation action "Replace From: with list address" DMARC Mitigate unconditionally "Yes". But list posts still have the poster's From:, breaking DMARC. How can I debug this? For a start, I looked in my sqlite database. Changes on the web interface list settings seem to be correctly applied to the database. But I don't see a "munge_from" in the fields of a list in the database. -- Written by Thomas Krichel http://openlib.org/home/krichel on his 21181st day.
