Re: Mailman, etc. upgrade woes and persistent bugs
by Abhilash Raj
I am trying to distill some information from this discussion to be
used for the implementation in Postorius. I'll maybe reiterate a bit
of what Steve was saying just to confirm I am on the same page.

So it seems like we have some sort of agreement that we need all the
roles to be able to see all the 4 states. Roles here are basically Admin(
i.e. list owner/moderator/site admin) and Subscriber.
There is no access control to transition "from" any state but each value
of non-enabled states is sort of a role's way to disable the delivery. Not
all states are settable by all roles.
1. A subscriber can only transition from any to "enabled" or "by_user"
state but can see if delivery was disabled "by_admin" or "by_bounces"
as separate state in the Options page.
2. An admin can transition to "enabled", "by_user" and "by_moderator".
They should use "by_user" when acting on behalf of the user and other
when there are any administrative reason to disable delivery, whatever
that may be. I expect "by_admin" to be used sparingly, and I don't see
any use cases for it.
3. Mailman itself will use the "by_bounces" to disable delivery due to
bounces.
Is that an accurate description?

I don't plan on shutting down the host anytime soon, so hopefully, I
remember to the next time it restarts.
I started out with Fedora the year before it adopted systemd, so I never

I'm totally fine with this because that's why we setup the host, although
one thing I noticed in the logs was that other servers
trying to connect to the host was rejected, they're trying to send logs to
a mailing list, which should work just fine but then it seems
they need to connect to this host.

The logs don't show Dovecot complaining about binding to port 24, the only

Which log is this? I would guess it's the mailmanweb.log.

This is the front-end gunicorn WSGI server, handling a request for
Postorius.

This is the Python socket library actually talking to the REST API of
Mailman core. An unspecified error occurs in the C code. It is not
handled.

This is the "Something's wrong, hope you have a clue 'cause I don't"
last line of defense error handler.
My guess is that it's a timeout on a socket.
I think you should also see log messages and a traceback in the
mailman.log.
The timeout for the mailmanweb gunicorn is configured in the gunicorn
conf file, usually in /etc/mailman3. This is relatively short (I
think my installation is default at 120 seconds).
The timeout for the REST API gunicorn is in
site-packages/mailman/config/gunicorn.cfg. This is long (360 seconds)
so if my conjecture about timeout is correct it's the mailmanweb
gunicorn that's timing out. If you need to change this one, you may
be able to simply put "timeout: 360" in the [webservice] section of
your mailman.cfg file, but if that doesn't work you can copy
gunicorn.cfg to /etc/mailman3/rest-wsgi.cfg, change the timeout in it,
and add "configuration: /etc/mailman3/rest-wsgi.cfg" to the
[webservice] section of mailman.cfg.

Templates branch for Mailman 3.1
by Barry Warsaw
Hello developers!
There are three big features still in progress for Mailman 3.1, the templates
branch, MySQL support, and unsubscription workflow. There is already a merge
request for MySQL support and I'm hoping to merge that soon. Abhilash is also
working on the unsubscription workflow feature but there's no MR for that yet.
The templates feature is very nearly done, so I think now is a good time to
ask for testing, feedback, and review. This is a generalization of the
welcome_message_uri feature in MM3.0 where you could specify e.g. the welcome
message as a URL to download and cache when necessary. This is important
because Core doesn't know whether there is even a web ui (e.g. Postorius)
involved, or where things like clickable links to unsubscribe would be. Sites
also want to customize footers to include information like codes of conduct,
etc.
Now (or when this branch lands), you will be able to specify a URL to retrieve
any template that Mailman uses internally, whether they are confirmation
messages, bounce probes, welcome and goodbye messages, etc. These can be
templates for administrators, users, and members.
Because I'm hoping to get some reviews, I'll point you at the documentation
for more details:
https://gitlab.com/warsaw/mailman/blob/templates/src/mailman/rest/docs/temp…
The branch did end up being much bigger and tentacled than I expected, but
it's all hanging together pretty well now, and all the tests pass. There's
still a small number of to-dos, but some of them will get punted, and the
others won't have a major effect on the overall use and visibility of the
feature.
https://gitlab.com/warsaw/mailman/blob/templates/TODO.rst
Note also that if you interact with the REST API v3.0, nothing changes
externally, but the old IMailingList attributes are mapped onto the new
templates mechanism. API v3.1 is where you see all the actual new feature
end-points exposed. Of course, any MM2 list converted to MM3.1 will use the
new templates stuff too.
Feedback very much welcome, either here or on the MR:
https://gitlab.com/mailman/mailman/merge_requests/170
I'd like to land this some time in the next week or so. Then I'll work on the
other two big branches and start to release some betas.
Cheers,
-Barry

Hi Guillermo,
We've faced the same issue and already reported it:
https://gitlab.com/mailman/mailman/-/issues/1044
I would not recommend anyone using MySQL/MariaDB database engine upgrade to
the latest version yet.

This would not be worth doing with generic ACLs from Postorius, unless
the list had (many) fewer than 100 users. What I'd end up doing (and I
bet you would too) is write a 15-line mailmancli script that extracted
membership information and then created the ACLs. But you'd still
have to modify the Django templates, I suspect, and perhaps database
schema.
Essentially the same 15 lines could be put into Mailman itself without
ACLs, and checking ACL membership is not going to be much, if at all,
faster than checking list membership.

Not sure what you mean by private and public here, but if you mean
which changes we should maintain and which changes you should maintain
locally, I haven't seen anything in this thread that we wouldn't want
to offer all Mailman 3 users. From Abhilash's and Mark's posts, I
believe they feel that way too. It's just a question of whether a
very general implementation is needed/worthwhile.

Probably should've read more of the thread before previous reply ;-)
So, the issue _could_ be due to latency to the remote database vs local
database that we have on m.p.o. Mailman3 is not very efficient when it
comes to total no. of database queries done per operation, which is
something I have been (very slowly) tracking and fixing on a
case-by-case basis.
So, for example, handling 1 held message in m.p.o made 1.1k postgres
database calls in total and even though they were each only few hundred
micro-seconds each, the total added up to roughly ~2sec avg response
time on the handle message API endpoint. If you handle more than 1, it
scales linearly.
My suspicion is that in your case Dan, due to a remote instance, the
latency per call is higher (maybe in the order of few or 10s of
milliseconds is my guess?) and then depending on the total no. of
entries you have in pendings and pendedkeyvalue tables (with some
filters, not _all_ entries), it adds up to a high value.
The no. of database calls here is of order n^2, where n is the entries
in pendings of type "held message" and "data" and their respective
linked relationships in pendedkeyvalue table.
My MR makes it such that we don't need to scan all entries of
"type"="data", so that part will become constant time. And the pending
of type "held message" will be limited to no. of held messages in a
single MailingList(compared to all mailing lists like today), so it will
help depending on the distribution of held messages in various lists. I
am also exploring ways to make that 2nd query also constant time.

Re: MM3 Postfix FROM header issue
by eboltz＠lhtservices.com
Mark,
Thanks for the assistance thus far.
When I create a new Domain within Postorius. If I set the Mail Host to 'example.com' and the Alias Domain to 'lists.example.com', create a new list such as 'staff_test', it'll default to the 'example.com' domain (which is the real domain). Then when I subscribe, I'll get an email from 'staff_test(a)example.com', when I want it to be from 'staff_test(a)lists.example.com' instead, also if I reply back to the 'staff_test(a)example.com' then I"ll get a bounce-back that it doesn't exist, but if I send to 'staff_test(a)lists.example.com' it'll go to the newly created list. I'd like all defaults to be '@lists.example.com', if that makes sense.
Here are the settings of my postfix_lmtp and postfix_vmap

The right place to get help regarding these guides would be the author of
the posts, which AFAIK, have no affiliation with Mailman Core Team.
On a (very) quick glance, it seems fine.

How much memory do yo have in your VM? Have you tried using a bigger VM?

I already started out on the above route. Its an adaptation because I
am running Fedora. I had no problem with system-wide installations via
dnf package management. However, some parts of the documentation does

I will come to this eventually (assuming that does not break things
later). I aim to get it all working with regular pip packages first. I
have installed mailman core already.
Fedora expects mailman files to reside at /usr/lib/mailman. It appears
to ship with a mailman unix user. I adapted to those system defaults.
Now I observe that "su - mailman" gives me the proper prompt but
.bashrc doesn't kick in. I still have to manually change to the
virtual environment despite setting the automatic change in .bashrc.
However, "su mailman" runs .bashrc but the prompt says "bash X.XX $".
Is this normal?
Subsequent parts of the doc show the path "/opt/mailman/mm/var/*" which
should correspond to "/usr/lib/mailman/mm/var/*" on my instance.
However, I don't see any instructions on how to get the "/mm" folder
and the associated sub-folders. I just have "/usr/lib/mailman"
I am lost
"pip list" within the venv environment confirms that I have "mailman
3.3.5". What am I missing?
