As Simon mentioned, try using DEBUG=False, if you don't already have that. With DEBUG=True, you should see emails printed in a `emails` directory under `mailman-suite_project` directory. This is a confirmation email to verify the email addresses, which happens even if you create an account from command line. > That being said, the enormous number of configuration files to consider > and dozens of cross-references to other pages in the docs make the > installation guide hard to follow; it also lacks logical structure in my > opinion, when it refers to parts of the configuration which are later > explained.

There are only two primary configuration files (there are a few more for finer configurations ;-): - mailman.cfg: This is the configuration for the Core engine and can be located any of the places mentioned in [1] or pointed to by environment var MAILMAN_CONFIG_FILE. - settings.py: This is the configuration file for Django under `mailman-suite_project` and controls the frontend (Postorius & Hyperkitty). Django is a huge framework with literally 1000s of options. It would be impossible to copy that information from Django's documentation and keep it updated in our docs. Hence, we have links to appropriate places when needed. Same goes out for the rest of the libraries that we use. All the settings mentioned in the documentation go to either of these files, except, when configuring web server and mail server. Please open an issue[2] if it is not clear where a particular configuration snippet goes and we will fix it.

Re: Installing Mailman3 on Debian Bullseye

Is that correct? > > Correct. This means that you're stuck with the Debian version of the Mailman 3 suite until they update which can be slow. Mailman 3 is now mature enough that if you're still happy with the Debian version a month after installing, you'll probably still be happy with it when Debian updates. It's a good tradeoff for the majority. But for example mixing a "testing" Mailman with a "stable" Python is likely to end badly because we frequently upgrade required levels of dependencies. So you either have to get a Debian upgrade of Mailman of your current Debian version, or you need to move to a whole not-stable Debian system. Not a pleasant choice if you think you need new features or a bugfix *now*. This is why we recommend the venv or other isolated installations. They allow you to upgrade the dependencies as well as the core packages without interfering with the rest of your system. > IIRC I got some errors about handling characters encoding if I > don't set up charset in language.master and language.en > section. But the memory is vague and I don't want to go back > retesting that... I suspect that you set up charset in .master and realized that it doesn't work because .en overrides it with ASCII, and then fixed .en. That's what happened to me. > Honestly I was totally confused by all these, and as I have said, > the MM3/Django/Hyperkitty/... documents didn't help much. Upstream documents are rarely very helpful with whole sets of large packages from distros in my experience. You install the packages, you go through a bunch of configuration screens, and you finish knowing *nothing about how anything works*. Then you need a little tweak that the configuration screens don't deal with, and you don't even have the vocabulary to grep or Google effectively. :-( Then again, I'm the kind of person who prepares to sleep by reading software manuals. ;-) But I do think you lose quite a bit of knowledge by using packages, and it's painful to find obscure details without it. Django doesn't actually show its face much in Mailman, so Django docs are not much use even to the site admin, unless you actually hack on Mailman. The only exceptions are authentication and the template language. Authentication is just hard, with more details then the Lego set in the Lego store. The templating docs are pretty good, IMO. The Mailman docs are in somewhat sad state. The content is actually quite comprehensive and detailed as these things go, but much of it is hard to discover. The original idea was to keep the docs in the sources, as doctests for examples and in the docs directory for exposition. These docs are more developer-oriented, obviously. Then there were several attempts to create a suite package which would require core, Postorius, and HyperKitty and streamline the setup process. The "mailman-suite" version came with a companion "mailman-suite-docs" package, which I think is now the basis for mailman.readthedocs.io aka docs.mailman3.org. However mailman-suite turned out to more trouble than it was worth, and mailman-web was developed to address the more useful approach of unifying some mailman-to-Django APIs for Postorius and HyperKitty (the django_mailman3 package) and configuration (a unified settings.py, as well as standardized top-level urls.py and views.py). Of course each of these contributed more documentation, some of it redundant, older versions left to slowly become obsolete (ie, incorrect) .... "Someday" I'd like get the documents reorganized, eliminate as much redundancy as possible and make things more discoverable. But it's a mammoth task. Steve

In addition to implementing the frontend the way I want it (expose/hide feature that are useful/unuseful to our users), I want to fully customize the visual appearance to represent the SaaS offering properly. This is exactly the reason why Mailman core was decoupled from archiving and the web UI. HyperKitty and Postorius were developed because we knew that almost no one would use Mailman core without archiving and a web management UI, but we always hoped that others might develop and contribute other web based archiving and management interfaces. Brian Carpenter of EMWD who tragically died of COVID did exactly that with his Affinity and Empathy PHP applications that interface with Mailman core via the REST API. EMWD hosts lists that use those interfaces, and had Brian not died, some version of those might be open sourced, but his initial thrust was to keep them proprietary for his business reasons. There is an early description of Brian's concept for Affinity at https://gitlab.com/mailman/affinity. > *** we're not try to hide that Mailman is in the equation, just how the overall interface is visually represented *** > > That all being said, on a slight segway... Aside from using the REST API, is it practical or possible to manipulate the database directly? That is, in doing so would it just work or are there extra moving parts when an API request is issued? It probably is possible, but I would definitely discourage it. The REST API should provide everything you need without your having to reimplement everything it does. -- Mark Sapiro <mark(a)msapiro.net> The highway is for gamblers, San Francisco Bay Area, California better use your sense - B.

While a user was able to send a message previously that contained an image, I was unsuccessful. It should be the same as Mailman 2.1. What are your settings for content filtering. In Postorius the only thing exposed are Settings -> Alter Messages -> Filter content, Collapse alternatives and Convert html to plaintext. If this Filter content Yes, content is filtered according to the other two settings and MIME parts may be removed according to the list settings filter_types, pass_types, filter_extensions and pass_extensions. These settings exist in core, but aren't exposed in Postorius. For a new MM3 list these settings are empty, but for a list imported from Mailman 2.1, they are set according to the corresponding MM 2.1 settings.

Deactivate list without deleting it?

by Colin Watson

Hi, I'm experimenting with a port of Launchpad's mailing list infrastructure to Mailman 3. If Barry's reading, he may remember that this is no trivial task, so I'm very definitely not promising that it will be done any time soon. :-) However, for the most part it looks relatively tractable with the aid of the plugin improvements in Mailman 3.2.0; I have the rough outline of a plugin that implements much the same feature set as our current pile of monkey-patches against Mailman 2.1 in a much nicer way. One of the major things I haven't figured out yet is list deactivation and reactivation. In our current 2.1-based code, you can deactivate a list in a reversible way, which basically tars up the list directory so that the list archives can be restored later. This isn't a native operation in 2.1, but it could be done because everything lived on the filesystem. In 3, it's less trivial. We could go to some effort to dump things out of the HyperKitty database and restore it on reactivation, but that seems rather complex and a bit silly. Ideally, I'd like mailing lists to have a "deactivated" state in addition to full deletion. In this state, the list would appear nonexistent for most purposes: incoming email would be rejected, Postorius would deny its existence, etc. There'd need to be corresponding extensions to the IArchiver interface which caused the archiver to put its archives of that list into a corresponding deactivated state, in which it would retain the messages but queries for them would return 404 or similar; these extensions would need to be optional, since while it should be relatively easy to do this in HyperKitty it could be hard or impossible for other archivers, and perhaps this should be a separate operation from deactivating the list itself since people may want to close a list while leaving its archives accessible. Has there been any discussion of this in the past, or any advice as to implementation strategy? Thanks, -- Colin Watson [cjwatson(a)ubuntu.com]
