Introducing Mailman Web project
by Abhilash Raj March 24, 2019

March 24, 2019

I have been working on a new sub-project Mailman Web[1][2]. This project basically combines Postorius and Hyperkitty together in a single package which you can easily use to serve Mailman's web interface. The basic motivation behind this was to make it simpler for people to install the web interface *and* make it easier for people to configure Mailman's web ui. Both Postorius and Hyperkitty are based on Django Web Framework, which uses settings.py as its default configuration language. While it is quite convenient for Python developers to be able to put Python statements in configuration to join/edit/configure settings. However, I think a traditional INI, or TOML style configuration is easier for non-developers without having to worry about PYTHONPATH, valid Python sytax etc, etc. For this reason, I decided to combine all the projects together into a Django project which can be easily installed and run: $ pip install mailman-web # Export Settings for commands to just work. $ export DJANGO_SETTINGS=mailman_web.settings $ django-admin migrate $ django-admin runserver This should get you default settings for running. If you want to customize your installation, which you almost always would need to in a prod environment, you can create a config file at one of these locations (which are searched in following order): - /etc/mailman-web.toml - /etc/mailman3/mailman-web.toml - ./mailman-web.toml Note that we support only TOML as the configuration language[3][4] because of its simplicity. I would have loved to use INI, like Mailman Core, but it turns out to be way too simple to represent more complex data structures like maps and tables, that is commonly used in Django's Settings. This project is currently in alpha stage (I created it today!), but can be installed with pip[5] and in my basic tests works. There isn't much in the project itself beyond some configurations. I also took this opportunity to document all the settings that are used in Mailman Web (both Postorius and Hyperkitty) together[6]. This is documented in code and so I really hope that it won't go out of date like many other places ;-) Improvements to docs is very welcome, just a modification of a comment and is quite easy to propose right in your web browser using Gitlab! Any questions, comments or suggestions are welcome. You can open issues for feature requests on gitlab[1] too.

Mailman Core 3.2.2 is now out
by Abhilash Raj March 24, 2019

March 24, 2019

Hello Everyone, Mailman Core 3.2.2 is released and available on PyPI[1]. This is a regular bugfix release and I had to do that to fix a version constraint which pulled in a pre-release of a dependency (falcon) when installed via pip and caused the default install to break. There are few other changes included in this release, including a big refactor of error reporting in Core's REST API. All the error responses are now correctly formatted as JSON with more information about the error. For example, invalid inputs for Enum data types return the valid options. Other error message are now generated from the input validtor and will be more informative. REST API also accepts input as JSON formatted body, alongside the x-www-form-urlencoded. A full list of changes are available here: https://mailman.readthedocs.io/en/latest/src/mailman/docs/NEWS.html#id1 This release supports Python 3.5-3.7. Thanks very much to all the contributors involved in this release. [1]: https://pypi.org/project/mailman/ -- thanks, Abhilash Raj (maxking)

Removing of bounce address from client.users?
by Aaryan Bhagat March 18, 2019

March 18, 2019

Let's say I have an email subscribed to multiple lists and almost all of them are generating bounce messages upon sending to that address. It is pretty much it is confirmed that this address is now stale and does not work now. Except from unsubscribing it from the lists I also think it would be wise to remove it from client.users. I need some pointers regarding if this should be applied or not? Am I missing some crucial info here?

Regarding GsOC proposal submission.
by Aaryan Bhagat March 17, 2019

March 17, 2019

For the project idea "Add support for bounce processing in Core" which I mentioned in the threads <https://mail.python.org/archives/list/mailman-developers@python.org/thread/… <https://mail.python.org/archives/list/mailman-developers@python.org/thread/… and got valuable inputs. I have drafted a basic version of idea------what should be implemented and how. But where should I post it ?

How strict are the dependencies on the django-compressor related backends?
by Christian Ehrhardt March 15, 2019

March 15, 2019

Hi, I was evaluating the Dependencies of mailman3 in Ubuntu and I was wondering if I could cut them down a bit. One thing that got my attention is the dependency from mailman3-web [1] to nodejs for less [2] and ruby-sass [3]. I was wondering if we could by default not install node-less/ruby-sass and what exactly that would imply. I have seen they are used for python3-django-compressor integration, but not a lot of actual LESS or SASS snippets in any related package. So I was wondering if that could be optional. Unfortunately I lack the expertise in that area, so I wanted to ask the mailman3 developer and user community: - could mailman3 work fine without those packages (making them a suggest instead of a depends) - what features would be lost exactly to a user and/or admin of mailman3? - I guess we would have to modify the default config at [4]or [5] then - any hints? I'd be very pleased if you could help me to check the doability and the impact of that dependency change. Thanks in advance, Christian P.S. Sorry - had to resend after full subscription (not only defining user at mail.python.org) to avoid the auto-reject [1]: https://salsa.debian.org/mailman-team/mailman-suite/blob/master/debian/cont… [2]: https://salsa.debian.org/mailman-team/mailman-suite/blob/master/debian/cont… [3]: https://salsa.debian.org/mailman-team/mailman-suite/blob/master/debian/cont… [4]: https://salsa.debian.org/mailman-team/mailman-suite/blob/master/mailman-sui… [5]: https://salsa.debian.org/mailman-team/mailman-suite/blob/master/mailman-sui… -- Christian Ehrhardt Software Engineer, Ubuntu Server Canonical Ltd

What is the processing time of bounce events?
by Aaryan Bhagat March 14, 2019

March 14, 2019

Good insight and starting point was made by Mark Sapiro and Stephen J.Turnbull in this thread <https://mail.python.org/archives/list/mailman-developers@python.org/thread/…> regarding the status of bounce processing in Mailman3 and how to move ahead on this. Current problem is I am facing is---- Given a list of registered bounce events in queue for processing. Does their processing time/method affect the other operations ( other runners especially ) of the server. This is important as their dependency or independency will decide the complexity of the process we should adopt for removing the subscriptions.

API best practices - REST or core?
by Derek Lambert March 14, 2019

March 14, 2019

I’m writing some code to update maillist owners based on data from another system. Are there any specific recommendations around using either the REST API or core over the other? Either should work for my case. Thanks, Derek Lambert

Doubt regarding definition of "temporary and permanent failures"
by Aaryan Bhagat March 13, 2019

March 13, 2019

Are "temporary and permanent failures" mentioned in "bounce.py" in "mailman/src/mailman/runners/" the same as "soft and hard bounces" respectively?
