UnpicklingError on mailman lists command
by Bryan Loniewski Aug. 4, 2021

Aug. 4, 2021

Hi all -- I'm getting the error below when trying to exec the "mailman lists" command. I've turned debugging on within my test mailman.cfg like so... [database] class: mailman.database.mysql.MySQLDatabase <snip> debug: yes [logging.database] level: debug path: dbmailman.log and can see a lot of info including the row(s) with each lists data returned in dbmailman.log. Any guidance on further troubleshooting/debugging? Note that listing the members returns fine (at least for the handful of lists I just tested, i.e., /opt/mailman/mm/bin/mailman members bry_test(a)lists-test.rutgers.edu) $ /opt/mailman/mm/bin/mailman lists Traceback (most recent call last): File "/opt/mailman/venv/bin/mailman", line 8, in <module> sys.exit(main()) File "/opt/mailman/venv/lib/python3.6/site-packages/click/core.py", line 829, in __call__ return self.main(*args, **kwargs) File "/opt/mailman/venv/lib/python3.6/site-packages/click/core.py", line 782, in main rv = self.invoke(ctx) File "/opt/mailman/venv/lib/python3.6/site-packages/mailman/bin/mailman.py", line 68, in invoke return super().invoke(ctx) File "/opt/mailman/venv/lib/python3.6/site-packages/click/core.py", line 1259, in invoke return _process_result(sub_ctx.command.invoke(sub_ctx)) File "/opt/mailman/venv/lib/python3.6/site-packages/click/core.py", line 1066, in invoke return ctx.invoke(self.callback, **ctx.params) File "/opt/mailman/venv/lib/python3.6/site-packages/click/core.py", line 610, in invoke return callback(*args, **kwargs) File "/opt/mailman/venv/lib/python3.6/site-packages/click/decorators.py", line 21, in new_func return f(get_current_context(), *args, **kwargs) File "/opt/mailman/venv/lib/python3.6/site-packages/mailman/commands/cli_lists.py", line 78, in lists for mlist in list_manager.mailing_lists: File "/opt/mailman/venv/lib/python3.6/site-packages/mailman/model/listmanager.py", line 100, in mailing_lists MailingList._list_id).all() File "/opt/mailman/venv/lib/python3.6/site-packages/sqlalchemy/orm/query.py", line 3246, in all return list(self) File "/opt/mailman/venv/lib/python3.6/site-packages/sqlalchemy/orm/loading.py", line 101, in instances cursor.close() File "/opt/mailman/venv/lib/python3.6/site-packages/sqlalchemy/util/langhelpers.py", line 69, in __exit__ exc_value, with_traceback=exc_tb, File "/opt/mailman/venv/lib/python3.6/site-packages/sqlalchemy/util/compat.py", line 178, in raise_ raise exception File "/opt/mailman/venv/lib/python3.6/site-packages/sqlalchemy/orm/loading.py", line 81, in instances rows = [proc(row) for row in fetch] File "/opt/mailman/venv/lib/python3.6/site-packages/sqlalchemy/orm/loading.py", line 81, in <listcomp> rows = [proc(row) for row in fetch] File "/opt/mailman/venv/lib/python3.6/site-packages/sqlalchemy/orm/loading.py", line 589, in _instance populators, File "/opt/mailman/venv/lib/python3.6/site-packages/sqlalchemy/orm/loading.py", line 726, in _populate_full dict_[key] = getter(row) File "/opt/mailman/venv/lib/python3.6/site-packages/sqlalchemy/sql/sqltypes.py", line 1708, in process return loads(value) _pickle.UnpicklingError: pickle data was truncated ________________________ Bryan Loniewski Rutgers University OIT:EAS:Messaging and Collaboration Services System Administrator

web api
by Ethan Furman Aug. 4, 2021

Aug. 4, 2021

Greetings again! Is there a remote API I can use to manage a list? One of the lists I manage has 1800 or so users, the vast majority of which have never posted, and I need to remove them (preferably not one by one). The list is meant to be actively used, so going forward I want to be able to unsubscribe anyone who hasn't posted in the last year. Both of those would be much more nicely done with a python script on my computer if I had a means to communicate with the mm3 server remotely. Any and all help appreciated! -- ~Ethan~

at the finish line of mailman3 docker, but can't sign in.
by bob B Aug. 2, 2021

Aug. 2, 2021

I am trying to setup mailman3 in docker and have some questions, I can see the finish line :) i hope. I start my images and I can access the web,http://Servername.domain.com/postorius/lists/ and no list are there of course, but How do i sign in? I click the forget link and I have to enter in a email address. I put in the email address I added to the docker-compose.yaml but that does not wrok. I have these setup in the .yaml file. MAILMAN_ADMIN_USER: The username for the admin user to be created by default. MAILMAN_ADMIN_EMAIL: The email for the admin user to be created by default. I found this url http://Servername.domain.com/admin/login However I never set a password and here is no forget button, Basically once I have docker installed, and mailman3 up and no lists are available, How do I setup or/and sign in as admin? Also In docker how can I test sending mail? the command "mailman-web sendtestemail youremailid@domain" from the mailman-web container does not work. How can I make sure my containers can send and receive mail?

migration
by Dave McGuire July 31, 2021

July 31, 2021

Hi folks. Some time ago, I set up mm3 and have been running a bunch of lists on it with great success. I was a long-time mm2 user, and while the differences are significant, I'm glad I made the switch. However, in what seems to have been a moment of insanity in retrospect, I installed mm3 from my OS' package repository. Yeah, I know, that was dumb. Now I'd like to migrate to a new server, and I'd like to install mm3 in the normal way. Is there a way that I can "dump" the configuration from an existing mailman3 server, and "import" it into a new instance? I'd really like to avoid re-doing all of the configuration, etc, as there are quite a few lists and everything is set up pretty much the way I want it. I would appreciate any advice from this learned group. Thanks, -Dave -- Dave McGuire, AK4HZ New Kensington, PA

Mailman lifecycle
by eugenio.jordan＠esa.int July 30, 2021

July 30, 2021

Dear all. Perhaps this is a sort of dummy questions for software supported by the Community, my apologies in advance. I have been asked on information related to the end of life of support for 3.1 version, and I was wondering whether you could please provide some insights on how the Mailman life cycle is conceived. For instance, are there periodically planned releases, say 1 per year? If so, will you please confirm how long we are to expect the previous versions to be maintained? Thanks so much in advance for the help. Best regards.

Footer question...
by David Partain July 27, 2021

July 27, 2021

Hi, Background: I have a painful mailman3 installation based on ubuntu 18.04 packages, a mistake I regret but have to live with until I can finish a fresh install of the latest. Currently running on mailman 3.1.1-9 and python-django-mailman3 version 1.1.0-4 (if that matters). I migrated > 1200 lists from an old mailman2 installation. That brought along all of the footers (naturally), and now I'm trying to get rid of them but failing miserably. I've spent a fair bit of time reading archives of this list, but I'm still stuck. Here's what's configured... In /etc/mailman3/mailman.cfg: -------------------------------------------------------------------------------------------------------------------------- var_dir: /var/lib/mailman3 # Root directory for site-specific template override files. template_dir: $var_dir/templates -------------------------------------------------------------------------------------------------------------------------- In that directory, list-specific directories like: /var/lib/mailman3/templates/lists/list.mydomain/ and, as an example, en/list_member_digest_footer.txt For the migrated lists, that might have: ------------------------------------------------------------------------------------------------------------------------- _______________________________________________ $display_name mailing list -- $listname To unsubscribe send an email to ${short_listname}-leave@${domain} ------------------------------------------------------------------------------------------------------------------------ Based on what I've read elsewhere, my first attempt was to create an empty file doing 'cp /dev/null list_member_digest_footer.txt' to replace the one installed in migration. That had no effect. As a shot-in-the-dark, I did 'cp /dev/null list:member:regular:footer.txt' to see if that might have some effect. Nope. I suppose some decision is made earlier in the process to tack on the footer, so these files I'm manipulating have zero effect. Anyone have suggestions of what I can do? Thanks in advance. David

requiring questionnaire from new users
by Ethan Furman July 27, 2021

July 27, 2021

Greetings! Is there a way to require new users to answer a questionnaire when they subscribe? I suspect that one of the lists I manage is getting a lot of subscribers who don't understand what that particular list is for, and having to answer a question or two would allow me to direct them to better resources. Any and all info appreciated! -- ~Ethan~

non-members issue with held email
by Lars Schimmer July 20, 2021

July 20, 2021

Hi I want to check a issue with a few mailing lists of us. We do run mailman3 on debian with debian package 3.2.1-1 (not yet updated for backup reasons). We created a new mailinglist, added 3 owner and several members. Now we want some email addresses to post to that list but not receive mails from the list. So I added those to the "non-member" area of the mailinglist and checked every non-member to "acceppt at once". But on a test, a email address, which is owner AND non-member, cannot send to mailinglist, always get a "HOLD: ...... The message is not from a list member" The Email address in that HOLD log entry is the same as in the owner/non-member list. Any idea howto check the mailman3 logs for this case? Thank you.

Deleting default "example.com" domain breaks everything
by mcarter＠corneredrats.com July 18, 2021

July 18, 2021

Hello. I'm new with v3 of mailman. Installed via aptitude on deb10. After I logged in as admin, I created my actual domain, as "example.com" was there by default. I then deleted example.com, and everything broke. The only site I had was still using example.com. How do I either a) restore example.com in config or CLI (as web UI is completely broken now), or b) move my one and only "Site 1" to the domain I created? Thanks.

Debian10 pkg install: set up Postorius superuser?
by mcarter＠corneredrats.com July 16, 2021

July 16, 2021

Hey, all. I've installed mailman3 to replace mailman2 from the Deb10 package mailman3-full. Command line appears to work, but I had to manually add the Uwsgi module to get the user web site to run. I can't find a reference to what the default admin user password is, and running "python settings.py createsuperuser" doesn't work with error: root@mail:/usr/share/mailman3-web# python manage.py createsuperuser Traceback (most recent call last): File "manage.py", line 8, in <module> from django.core.management import execute_from_command_line ImportError: No module named django.core.management Any idea what else needs to get installed that the aptitude package missed? Any way to just manually set the admin's password without having to install anything else?
