after last upgrade I've got a CSRF failed verification
by Guillermo Hernandez (Oldno7) Sept. 5, 2025

Sept. 5, 2025

I did upgrade one of my mailman3 server after Abhilasj announcement: "I am pleased to announce several new releases for GNU Mailman project. 1. Mailman Core 3.3.6 1 <https://docs.mailman3.org/projects/mailman/en/latest/src/mailman/docs/NEWS.…> 2. Postorius 1.3.7 2 <https://docs.mailman3.org/projects/postorius/en/latest/news.html#section-2> 3. Hyperkitty 1.3.6 [3] 4. Mailmanclient 3.3.4 [4] 5. Django-mailman3 1.3.8 [5]" I did it via pip and all seems to be working, but when I try to discard or accept any message via postorius it shows a Forbidden 403 error CSRF verification failed. In my settings.py I have commented out these variables: # Other security settings # SECURE_SSL_REDIRECT = True # If you set SECURE_SSL_REDIRECT to True, make sure the SECURE_REDIRECT_EXEMPT # contains at least this line: # SECURE_REDIRECT_EXEMPT = [ # "archives/api/mailman/.*", # Request from Mailman. # ] # SESSION_COOKIE_SECURE = True # SECURE_CONTENT_TYPE_NOSNIFF = True # SECURE_BROWSER_XSS_FILTER = True # CSRF_COOKIE_SECURE = True # CSRF_COOKIE_HTTPONLY = True # X_FRAME_OPTIONS = 'DENY' I've been messing with them whith no results. It's like it lacked some value in some template... Can someone, please, point me in the right direction? Thanks in advance -- ___________________________________________ Mailman's content filtering has removed the following MIME parts from this message.

Dear Users, trying to update mailman3 to lastest version, we fail during mailman-web migrate with: Operations to perform: Apply all migrations: account, admin, auth, contenttypes, django_mailman3, django_q, hyperkitty, postorius, sessions, sites, socialaccount Running migrations: Applying account.0006_emailaddress_lower...Traceback (most recent call last): File "/opt/mailman/venv/lib/python3.10/site-packages/django/db/backends/utils.py", line 89, in _execute return self.cursor.execute(sql, params) File "/opt/mailman/venv/lib/python3.10/site-packages/django/db/backends/sqlite3/base.py", line 328, in execute return super().execute(query, params) sqlite3.IntegrityError: UNIQUE constraint failed: account_emailaddress.email We found a workaround to fake the migration with migrate --fake Operations to perform: Apply all migrations: account, admin, auth, contenttypes, django_mailman3, django_q, hyperkitty, postorius, sessions, sites, socialaccount Running migrations: Applying account.0006_emailaddress_lower...

I'm unsure if i should recover from snapshot or keep it going? Could this be some duplicate users with same mail-address? I have at least spotted one user and delete him. thank you. Stefan

Sept. 5, 2025

Hi all, i tried to install Mailman3 according to https://docs.mailman3.org/en/latest/install/virtualenv.html#virtualenv-inst…. I’m using Mariadb instead of PostgreSQL, but that is no problem until now. Where i fail: I have to make an entry var_dir: /opt/mailman/mm/var in /etc/mailman3/mailman.cfg. But there is no directory /opt/mailman/mm, and there are no subdirectories. No $var_dir, no postfix_lmtp, no postfix_transports. Where do i get those files from? TIA QNo

Question: as Admin, I disabled the self-registration via settings.py. What is the correct method to register a few new users now?
by Wikinaut Sept. 2, 2025

Sept. 2, 2025

Disabled by line ACCOUNT_ADAPTER = 'django_mailman3.views.user_adapter.DisableSignupAdapter' (via https://gitlab.com/mailman/django-mailman3/-/merge_requests/129 ) When I want to register a few new users, I need to comment this line and restart mailmanweb. Question: is there a better method for admins to register a few new persons to Hyperkitty/Postorius so that they can act as owners and moderators of some of the lists?

Mailing lists as the main collaboration centre at SME
by Rodrigo Camacho Aug. 31, 2025

Aug. 31, 2025

Hello all, I own and run a small company (lanao.org) I am looking for companies which have put mailing lists not only as a form of general announcement but especially as the main way to collaborate. I am thinking of moving my team to a model like that and would love to read about some best practices or strong opposition to the idea. I am hopeful that out there there are companies which have resisted the Microsoft Teams virus. If your company uses mailing lists to run, please reach out. We are currently using Gitlab issues to collaborate which has been quite successful. I would be very interested to trade tips. Best wishes, Rodrigo

Hi all, I'm just reviewing Stalwart as a many-in-one mailing system. Did anybody yet succeed in plugging mailman into stalwart (the incoming bit seems to be difficult)?

New subscribed (by invitation) user: no password received in invitation/welcome e-mail. Postorius sign up / password reset broken
by ^m'e Aug. 30, 2025

Aug. 30, 2025

Hi there, I migrated form MM2.1 to MM3.3.10 on Debian Trixie (mariadb backend) -- I know that's a bit unorthodox to ask here for help on a non venv-based installation, but hopefully I'll first gain a bit of insight of MM3 in order to formulate a more precise request to Debian maintainers. ## Issue #1. A newly invited (from Postorius mass subscription page) and confirmed user doesn't get any password in their invitation/welcome e-mail. I guess that's because MM3 allows a user to subscribe without having an account, right? Else, there's a problem. ## Issue #2 Anyway, if that new user asks for a password reset on Postorius they get "Server error An error occurred while processing your request." Log shows: ``` ERROR 2025-08-29 17:59:17,227 173488 django.request Internal Server Error: /accounts/password/reset/ Traceback (most recent call last): File "/usr/lib/python3/dist-packages/django/core/handlers/exception.py", line 55, in inner response = get_response(request) File "/usr/lib/python3/dist-packages/django/core/handlers/base.py", line 197, in _get_response response = wrapped_callback(request, *callback_args, **callback_kwargs) File "/usr/lib/python3/dist-packages/django/views/generic/base.py", line 105, in view return self.dispatch(request, *args, **kwargs) ~~~~~~~~~~~~~^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/usr/lib/python3/dist-packages/django/utils/decorators.py", line 46, in _wrapper return bound_method(*args, **kwargs) File "/usr/lib/python3/dist-packages/django/views/generic/base.py", line 144, in dispatch return handler( form.save(self.request) ~~~~~~~~~^^^^^^^^^^^^^^ File "/usr/lib/python3/dist-packages/allauth/account/forms.py", line 633, in save adapter.send_password_reset_mail(user, email, context) ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~^^^^^^^^^^^^^^^^^^^^^^ File "/usr/lib/python3/dist-packages/allauth/account/adapter.py", line 577, in send_password_reset_mail return self.send_mail("account/email/password_reset_key", email, context) ~~~~~~~~~~~~~~^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/usr/lib/python3/dist-packages/allauth/account/adapter.py", line 201, in send_mail msg.send() ~~~~~~~~^^ File "/usr/lib/python3/dist-packages/django/core/mail/message.py", line 299, in send return self.get_connection(fail_silently).send_messages([self]) ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~^^^^^^^^ File "/usr/lib/python3/dist-packages/django/core/mail/backends/smtp.py", line 134, in send_messages sent = self._send(message) File "/usr/lib/python3/dist-packages/django/core/mail/backends/smtp.py", line 152, in _send self.connection.sendmail( ~~~~~~~~~~~~~~~~~~~~~~~~^ from_email, recipients, message.as_bytes(linesep="\r\n") ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ ) ^ File "/usr/lib/python3.13/smtplib.py", line 861, in sendmail self.ehlo_or_helo_if_needed() ~~~~~~~~~~~~~~~~~~~~~~~~~~~^^ File "/usr/lib/python3.13/smtplib.py", line 611, in ehlo_or_helo_if_needed if not (200 <= self.ehlo()[0] <= 299): ~~~~~~~~~^^ File "/usr/lib/python3.13/smtplib.py", line 451, in ehlo self.putcmd(self.ehlo_msg, name or self.local_hostname) ~~~~~~~~~~~^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/usr/lib/python3.13/smtplib.py", line 378, in putcmd self.send(f'{s}{CRLF}') ~~~~~~~~~^^^^^^^^^^^^^^ File "/usr/lib/python3.13/smtplib.py", line 365, in send raise SMTPServerDisconnected('please run connect() first') smtplib.SMTPServerDisconnected: please run connect() first ``` The same happens if the new users tries to sign up. Any idea? Cheers -- Marco
