Hi Mark, yes, we are using a local copy of the gunicorn.cfg. It is in the home directory of our mailman3 instance (like the mailman.cfg, same directory). We will now look into the postgresql database - maybe there is an index missing or something like that. Thank you for help.

This is how Core actually does work[1] if you subscribe via Email and you already have a primary address. It will lookup a user using the address and if the address is the primary address of the user, it will subscribe the primary address. However, if it isn’t the primary address, and this is a new address, it will subscribe the address instead of user because the address isn’t verified at this point and hence can’t be a primary address. We could extend the subscription workflow to add an additional step to set this address as primary and subscribe the primary address. Postorius has the full ability to define its own workflow because REST API provides full expression capability and doesn’t enforce anything. Previous versions didn’t had support for subscribing as Primary Address, but that has since changed and is the default one in the dropdown. This is for authenticated subscription, the anonymous subscribe works similar to email -join command. Mass-subscribe is probably working the same way.

Like mentioned above, it should be possible to do what you suggest.

Primary Address is also an attribute of the Mailman User, so it should be possible for an admin to set that for a user if the user doesn’t have an account. When they sign up, they’d be able to manage and update accordingly. I have started working on designing a User management page[2] in Core which should make it easy for superuser to manage several things about a User, including the ones that don’t have an account in Postorius to manage their own. The list os “tasks” an admin can do isn’t decided, but please feel free to write comments there about things you’d like to be able to do as a server admin.

Re: Mailman backend maintenance task

by Eugenio Jordan (external)

Dear Steve: I really appreciate you also took your time to provide more insights on how Mailman works, and how their different components interact each other. There are two "minor" tasks and one major task that we would need to accomplish within PostGRESQL, namely rebuilding the index related to hyperkitty_email table primary key, rebuilding also another index on the very same table supporting an uniqueness constraint (these would be the minor); and running vacuum full on the whole database to effectively reduce the size of precisely hyperkitty_email table, which is the largest table in this database, and if possible retrieve back to the SAN the extra space we had to add to cope with that very table size increasing. The way vacuum full locks the tables are, among all the locking mechanisms provided by PostGRESQL to guarantee the transactional integrity, one of the strongest, if not the strongest one (as far as I know, the tables are more ore less recreated when running vacuum full). The idea we were considering was more or less stopping all of the components, then starting up only PostGRESQL, and then performing each one of the mentioned tasks. Actually our PG release allow "online" indices rebuild (drop + rebuild concurrently), but we did not want to assume the risk if, for whatever reason, new records were added to the table breaking the uniqueness of both constraints (fixing this cases turns out to be a real pain in most cases). Alternatively, we could lock the table ourselves to get more or less the same effect, true, although, after all, the final impact on potential connections willing to run DML would be the same. In other words, rather than having lots of transactions coming from whether core component processes or web component processes fail, we prefer to stop everything. But it's got of course the worst downside: we would receive Let me please now go back to your kind explanation to see if I did get things correctly. You mention that regardless the connectivity that Mailman's core processes might have with the database, the emails will be received by and queued until the connection is back again and they can be delivered to the distribution lists' members. Could you please confirm whether this task would be actually delegated to Postfix (or any MTA integrated with Mailman)? If so, this is actually what we need: we could afford delaying the reception a couple of days, whilst we are sure that no mail will be lost. Once more, thanks a lot for your kind help.

I have been following your discussion with Abhilash, and he's definitely the expert, especially if you are using the containers he creates and distributes. But there's some information here he hasn't mentioned yet. Please consider the following discussion to be background that allows you to understand some of the considerations. I've only run the Mailman 3 suite with all three running constantly on the same host, so I have no experience with this kind of issue.

Mailman core can certainly run without either Postorius or HyperKitty. Controlling Mailman core (moderation, helping users) without Postorius is annoying, but it can be done. If you stop the HyperKitty process, what should happen, I believe, is that posts for archiving will accumulate in the 'archive' queue until HyperKitty is available again. It's been a while since I studied this so I could be completely wrong, but as I understand it HyperKitty and Postorius are not daemon processes. Rather, they are WSGI applications, which means they are subprocesses spawned by your webserver, and controlled by it. In order to keep them from running, you would reconfigure the webserver to not call those WSGI applications. How that is done is specific to the webserver and the WSGI module. If you are running from Docker containers, most likely, you can just stop their containers. The larger problem is that Mailman core uses a RDBMS. Normally both Django and Mailman are referring to the same RDBMS, PostgreSQL in your case. I'm not familiar with the vaccuum operation; if it requires taking the whole RDBMS down, and Mailman is running on that RDBMS, you're out of luck. Mailman can accept posts and queue them, but it can't deliver them to subscribers without access to the RDBMS tables. If it's just a matter of locking some tables while other are available, then it should work because the tables used by core and HyperKitty are disjoint as far as I know. (I think Postorius and HyperKitty both use Django's user tables for authorization, so at least for those tables both Postorius and HyperKitty will have to be down, but core can continue running because its database is completely separate.) > Regarding the former, as far as I have read, the "mappings" lists > -> addresses are stored just in the database, so if we run some > kind of procedure or task like vacuum which will lock exclusively > tables, or want anyway to have the database stopped for a cold > backup or whatever, Mailman willl not work, that is, again the > mails addressed to the distribution lists will not be > delivered. Will you please confirm this point, too? That depends on how "vacuum" works. If you can tell the RDBMS not to lock Mailman core's tables, it can continue to run. Definitely if the database is not running, Mailman will continue to receive and store the posts, but it won't be able to distribute mail to subscribers until its tables are available again. At that point the queued posts will be processed normally, except that if there's a large backlog, they won't go out in a quick burst, it may take a while. One possible worry, depending on how you are connected to the Internet, is that your provider may interpret the sudden burst of outgoing mail when Mailman comes back on line as spam or some other sort of mischief. Mailman has no way to throttle this: it feeds messages to the MTA until the MTA says "stop". Then it waits until the MTA is ready again.

Postorius Suggestion: Give owner a view of all users of all owned lists

by Stephen J. Turnbull

Andreas Vetter writes: > it would be real great if owners that own several lists, but are > not superusers, can see all users of all *their* lists and manage > them. A down-"selected" version of the superusers view. > Would that be possible? Possible, yes. I don't know how to do it well enough to add to our distribution. Note that owners can't actually manage users -- that really does need to be a superuser. Owners can manage subscriptions to the lists they own. So first we'd want to create a new "Subscriptions" item for the top menu; the "Users" item isn't appropriate. I'm not sure who that item should be visible to. Most likely only owners, because individuals already have ways to see all their subscriptions, and it's not obvious they would want the same presentation as your superowners. Then you'd iterate over the logged-in owner's lists and collect all of the subscriptions. I guess you'd want them to be organized by address rather than by list. By User is out, I think -- owners can't normally see Users, and I'm unhappy abou the privacy implications of being able to correlate nole(a)alset.com with head(a)dodgy.gov in general, although I realize it's not a problem in your setting. Without a more complete specification of what your users need, and the presentation they'd want to see, I personally am unwilling to go farther than those comments. Maybe one of the other devs feels differently. Also, "domain owner" is way under-implemented currently. For the hierarchical situation you outline, all the problems go away for domain owners. Of course then you'd need to split out lists by domain, but to me that's a small cost to preserve sanity in the structure. Steve

Re: Listing/Exporting member list error: Mailman REST API not available. Please start Mailman core.

by Daniel Armengod

Can confirm the problem is reproducible on mailman 3.3.0 installed via PIP. Postorius hangs on exporting CSV subscribers [1] (~6k in this case), with error "Mailman REST API not available. Please start Mailman core" (which is otherwise running fine). mailman3.log also shows WORKER TIMEOUT log entry, exactly the same as OP's message. > You can add a new |gunicorn.cfg| next to your |mailman.cfg| and add > the additional options. For further reference if anyone reads this thread, see [2]. I had to look that up to figure out where the file name "gunicorn.cfg" came from. It's not immediately obvious to the reader why a file named "guincorn.cfg" should be specially interpreted by mailman3. The suggested fix - increasing timeout of worker process - did work perfectly for me. Thanks :) Regards, Daniel [1] http://www.<redacted>.org/postorius/lists/<redacted>/csv_view/ [2] https://mailman.readthedocs.io/en/latest/src/mailman/runners/docs/rest.html…

If it's purely a matter of managing subscriptions by individual users, that's the path of least resistance, I think. I would not be surprised if there are things you don't actually need, but you'd need to implement so that Postorius doesn't blow up if some IMember feature you haven't implemented gets accessed. If in the future you might have an external personnel database with other stuff in it, and you want Mailman automatically synced to that, then IMember now might make sense to avoid technical debt in the future.
