Re: Mailman REST API not available. Please start Mailman Core.
by Shashikanth Komandoor
Thank you Mark for your response.
I understood that gunicorn is a front end that is used like web server like
nginx.
But I don't think I am using it instead I am using the httpd to redirect
requests to postorius.
And I am starting the mailman-suite with the command "python manage.py
runserver 0.0.0.0:8000 --insecure &". Hope this does not use gunicorn
(which of course I don't know what it is until now).
Please correct me if any point I am mentioning is wrong.
So, in this case, do you think configuring gunicorn as below would work:
*calling gunicorn.cfg in mailman.cfg as below *
*[webservice]*
*configuration: /var/lib/mailman/mailman/src/mailman/config/gunicorn.cfg*
*and content of gunicorn.cfg as below*
*(venv3) [root@lsmgr mailman]# cat
/var/lib/mailman/mailman/src/mailman/config/gunicorn.cfg[gunicorn]# All the
options that can be put here are available at#
http://docs.gunicorn.org/en/stable/settings.html#settings
<http://docs.gunicorn.org/en/stable/settings.html#settings># No of seconds
to wait before killing the worker processes.*
*workers = 4graceful_timeout = 90*
Also what is the difference between timeout and graceful_timeout ?
Please help me if I can increase the management better. Any guide is also
helpful for me.

Doesn't 'apt purge -y mailman3 mailman3-web python3-django-mailman3 && apt
autoremove -y && \apt autoclean' achieve the same for a package-based
installation?
I'd keep /etc/mailman3 and /opt/mailman and just do chown -R mailman: those
two directories. I find it easy to edit files in /etc/mailman3/ as user
mailman.
Anyway, best of luck.
You are now on the right track.

Hi Mark,
Thank you for your kind answer. While I've been running a mailman site for many years, I'm just getting going with mailman3 (and migrating my 1400 lists...) and I feel lost occasionally :)

That directory has all of the messages sent to that list:

Yes, I'm still seeing the errors. When I send mail to a list with a cute emoji, I see the following in /var/log/mailman3/web/mailman-web.log:
ERROR 2021-01-28 10:58:45,708 16923 django.request Internal Server Error: /mailman3/hyperkitty/api/mailman/archive
(bunch of python errors omitted)
DataError: (1366, u"Incorrect string value: '\\xF0\\x9F\\x98\\x8A\\x0A\\x0A...' for column 'content' at row 1")
Also, a bunch of mail is sent to root, presumably one for every message that has previously failed, with the same error information, plus information about the POST method done. (If something there would be helpful, please let me know.)
Finally, I'm doing all of this on Ubuntu, with the packages available in the distro, which means:
mailman3 3.1.1-9
mailman3-doc 3.1.1-9
mailman3-full 3.1.1-9
mailman3-web 0+20170523-14
python-django-hyperkitty 1.1.4-4
python-django-mailman3 1.1.0-4
python-django-postorius 1.1.2-3
python-mailmanclient 3.1.1-5
python3-mailman-hyperkitty 1.1.0-4
Thanks very much for any help you can offer.
Cheers,

Removing the template allows normal subscriptions and the generic welcome message is sent out.

If this is from the installed settings.py, it isn't going to work,
since you specified a routable domain (I think, although
"list1.iitm.ac.in" is not in the public DNS), which will have a
routable address, not localhost.
What IP does your DNS report for "list1.iitm.ac.in"?
> HOSTNAME = 'localhost.local'
That isn't what you told Mailman via hyperkitty.cfg. I'm not sure it
matters, but I think you should make sure all the config files agree
on the name of the host.

This can be problematic, at least if you enable error messages by email.

Setting for archiving multi email domains?

What do you mean by "set"? That the list has archiving enabled?
What is in the Postfix logs? Where does Postfix try to deliver the
second class of email (list-specific domains)? Is there a "bounce"
(more precisely, a Delivery Status Notice telling you that the mail
was not delivered, and with luck, why Postfix had a problem)? What is
in the Mailman logs?
I assume from your description (one server, multiple domains) that
these list-specific domains are "virtual" domains that are handled by
the single server. It seems likely that something is going wrong with
the routing in Postfix.

(2) above will allow receiving mail for those domains, but is unlikely
to be sufficient for routing to lists. You also need to inform
Mailman about the virtual domains, because the internal name of the
mailing list includes the domain.
Postfix has extensive support for virtual domains. This is somewhat
tricky. Are you familiar with this support, as documented in
http://www.postfix.org/VIRTUAL_README.html, and the general docs? For
Mailman's needs from Postfix, see
https://docs.mailman3.org/projects/mailman/en/latest/src/mailman/docs/mta.h….
If the above aren't sufficient hints, we need more information about
both the Postfix configuration and the Mailman configuration.
In a later message
https://lists.mailman3.org/archives/list/mailman-users@mailman3.org/message…,
you report at the end of the traceback (line folded for readability):
> AttributeError: 'NoneType' object has no attribute 'preferences'

This seems to indicate that either your list has a member that doesn't
exist in Mailman's subscriber database or (maybe) that there are no
subscribers, because it's trying to get profile information about a
nonexistent list member (represented by the Python 'None' object).
Did this occur only once? How many messages are in the "shunt" queue?

i know.
the problem is, that right now i have a running (Debian-based, thus
outdated) mailman3 installation, and I still haven't found a proper
strategy to upgrade and keep staying up-to-date.
so for the time being i'm stuck with what i have.
>
> Something like the following in `mailman shell` can do it.
thanks a lot.
afaiu, this snippet allows me to purge outdated pending subscriptions.
modifying it slightly, also allows me to just list the pending
subscriptions along with their tokens and print them out.
is it still possible to just use these tokens to confirm the pending
subscription (even though it is long overdue)?
if so, i could just send out a reminder to those 50 or so people who
have not confirmed yet.
while investigating this a bit, i also noticed that it seems that with
mailman3 the only option to confirm a pending subscription is via email
("leaving the subject intact") - at least that is the only option that
is listed in the confirmation mail.
now i would like to massage this into what i think is a bit more
user-friendly.
first of all: most email confirmation systems allow me to either "reply
by email" or "click this link".
is there a way to do this for mailman3? that is: is there a (hidden) URL
that would accept the token in order to confirm a subscription?
also: the confirmation mail says that the subject must be kept intact.
however, i noticed that the actual "From" address of the confirmation
mail already contains the token.
would it be enough if people just sent an email to this special
email-address (that contains the token), regardless of the subject?
i'm thinking of sending a rather personalized email that has a more
attractive subject than "confirm flkdsajfsalkjflsajfsoisjdl".
finally: what else is required to approve the confirmation? will the
sender's email-address be taken into account? (e.g. if they subscribed
"foo+mylist(a)example.com" but send the confirmation-reply from
"foo(a)example.com", will that still work?
sorry for so many questions.
i *did* search the documentation, but simply haven't found anything that
would help me.
i've probably looked in the wrong places, but mailman3 is rather huge so
it's easy to miss the imprtant parts.

Exactly, and I have entered all the credentials from the "OAuth 2.0 Client
ID and Client Secret"
of the twitter developer portal.
https://webmail.kictanet.or.ke/~wash/twitter-oauth.png
I have checked my settings_local.py several times trying to find out why
