i have successfully set up mailman3 instance by following the guide at https://gitlab.com/mailman/mailman-suite-doc/blob/master/source/install/vir… and from this mailing list. my setup uses an alias domain i.e the mail server is different from the lists server. I have successfully created an alias domain and mailing list through Postorius but I keep getting this error in syslog. OSError: [Errno 99] error while attempting to bind on address ('xxx.xx.xx.xx', 8024): cannot assign requested address. Even when I change the port number, I still get the same error Kindly assist. here is my mailman.cfg config [paths.here] var_dir: /opt/mailman/mm/var [mailman] layout: here site_owner: postmaster(a)mail.example.com [database] class: mailman.database.postgresql.PostgreSQLDatabase url: postgres://mailman:#passwd@localhost/mailman [archiver.prototype] enable: yes # For the HyperKitty archiver.

Mailman 3 Hyperkitty indexes not being built
by tom＠gather.coop Oct. 19, 2022

Oct. 19, 2022

My config looks like this: HAYSTACK_CONNECTIONS = { 'default': { 'ENGINE': 'haystack.backends.whoosh_backend.WhooshEngine', 'PATH': os.path.join(BASE_DIR, "fulltext_index"), ... I have whoosh 2.7.4 installed. But my fulltext_index directory contains only one file, _MAIN_0.toc, which hasn't been updated in two years. What could be going on here? Presumably Hyperkitty should be indexing new messages as they are archived. I could run update_index to fix the index now but then it would just go out of date again. Also asked on SO: https://stackoverflow.com/questions/74055901/mailman-3-hyperkitty-indexes-n… Thank you!

URL-lines in templates get folded
by Frank Steinberg Oct. 18, 2022

Oct. 18, 2022

Hi, I’ve added links to some templates to give owners and moderators shortcuts to the postorius UI for moderation tasks, e.g., I’ve added https://lists.xxx.de/postorius/lists/$list_id/held_messages <https://lists.xxx.de/postorius/lists/$list_id/held_messages> Unfortunately those lines seem to exceed a certain limit and get folded, so that they appear as, e.g. https://lists.xxx.de/postorius/lists/$list_id/held_ <https://lists.xxx.de/postorius/lists/$list_id/held_> messages (or similar) and are not directly useful. Do you have any suggestion for this situation?

Upgrading packages
by Eggert Ehmke Oct. 13, 2022

Oct. 13, 2022

Hello Mark & all, I have the venv installation on my Debian 11 system running. I followed your suggestion to upgrade all packages. When upgrading hyperkitty by this command: pip install --upgrade git+https://gitlab.com/mailman/hyperkitty@master I noticed that mistune-2.0.0rc1 was upgraded to mistune-2.0.4. All packages were upgraded fine. I applied the patch to venv/lib/python3.9/site-packages/hyperkitty/lib/renderer.py to change the mistune import line. When I run now mailman-web migrate I get: *CommandError: Conflicting migrations detected; multiple leaf nodes in the migration graph: (0017_auto_20220628_1132, 0018_alter_emailtemplate_language in postorius).* *To fix them run 'python manage.py makemigrations --merge'* However, when I run the suggested command as: $ python ./venv/lib/python3.9/site-packages/mailman_web/manage.py makemigrations -- merge No conflicts detected to merge. Can I just ignore this behavior? At the moment, I don't dare to carry out these steps on my production system. Would be nice to shed some light on this. Eggert

Debian 11 mailman3 installation question
by William Oliver Oct. 13, 2022

Oct. 13, 2022

I have had an installation of mailman3 running for a year or so with no problems. This was a manual installation. I ended up having to change machines, so I decided to install using the debian 11 package. It seems to have gone well except.... when I restart mailman3 service, I get the following fail and error message: oot@emergenis:/etc/nginx/sites-enabled# systemctl restart mailman3 Job for mailman3.service failed because the control process exited with error code. See "systemctl status mailman3.service" and "journalctl -xe" for details. root@emergenis:/etc/nginx/sites-enabled# systemctl status mailman3 ● mailman3.service - Mailman3 server Loaded: loaded (/lib/systemd/system/mailman3.service; enabled; vendor preset: enabled) Active: failed (Result: exit-code) since Tue 2022-10-11 15:09:45 EDT; 8s ago Docs: man:mailman(1) https://mailman.readthedocs.io/ Process: 1056 ExecStart=/usr/bin/mailman -C /etc/mailman3/mailman.cfg start --force (code=exited, status=1/FAILURE) CPU: 9.193s Oct 11 15:09:43 emergenis.com mailman3[1056]: File "/usr/lib/python3/dist-packages/mailman/commands/cli_control.py", line 109, in start Oct 11 15:09:43 emergenis.com mailman3[1056]: call_name(config.mta.incoming).regenerate() Oct 11 15:09:43 emergenis.com mailman3[1056]: File "/usr/lib/python3/dist-packages/mailman/mta/postfix.py", line 133, in regenerate Oct 11 15:09:43 emergenis.com mailman3[1056]: raise RuntimeError(NL.join(errors)) Oct 11 15:09:43 emergenis.com mailman3[1056]: RuntimeError: command failure: /usr/sbin/postmap /var/lib/mailman3/data/postfix_lmtp, 1, Operation not permitted Oct 11 15:09:43 emergenis.com mailman3[1056]: command failure: /usr/sbin/postmap /var/lib/mailman3/data/postfix_domains, 1, Operation not permitted Oct 11 15:09:45 emergenis.com systemd[1]: mailman3.service: Control process exited, code=exited, status=1/FAILURE Oct 11 15:09:45 emergenis.com systemd[1]: mailman3.service: Failed with result 'exit-code'.

Oct. 12, 2022

Hi, Where and how do I set the default setting of "Delivery status" to be "Enabled". I'm not seeing any clues in mailman3-web/settings.py At the moment, a new subscriber is neither "Enabled" or "Disabled". Thanks, Mark

Performance issues with Mailman 3
by Wong, Wesley Oct. 8, 2022

Oct. 8, 2022

Hi, I am having some performance problems with Mailman 3 (version 3.3.5) when it sends out a lot of messages to people. We recently migrated from our old Mailman 2.1.x system to Mailman 3.x about 3 months ago. We host about 350 lists with membership counts varying between 10 to 1500 members on some of the lists. I noticed that outbound messages from Mailman to our outbound SMTP are getting delayed up to an hour when Mailman is processing a lot of messages going to lists. I was wondering if there are good performance tuning tips to be considered for Mailman 3 (i.e. OS, database and/os Mailman Core). I am running the setup on a VM. Here is my configuration for VM and OS: VM config: ESX 6.7 (CPU: Intel(R) Xeon(R) Gold 6242) 4 CPU 8 GB SLES 15 SP3 Python 3.9.10 MariaDB 10.5.17 Mailman 3.3.5 Thanks. wesley Wesley Wong Senior Systems Engineer Anderson Computing & Information Services | ACIS 310-206-2571 [ucla-logo---new_smaller] ___________________________________________ Mailman's content filtering has removed the following MIME parts from this message.

Mailman2 CLI commands for Mailman3
by Dave Hall Oct. 5, 2022

Oct. 5, 2022

Hello. Sorry if this is an old topic. I'm in the process of migrating from 2.1 to 3.2. In my use case one of the advantages of Mailman 2.1 vs services like Google Groups has been the ability to manage lists from the command line. Things like using sync_members to update the list for a committee when the membership of the committee is updated one a year, or like using find_members and remove_members to remove a user from all mailing lists when they leave the organization. Even the ability to script mailing list creation. So far I haven't found these commands in Mailman3. I hope there is a plan to add these soon. Thanks. -Dave -- Dave Hall Binghamton University kdhall(a)binghamton.edu
