problem configuring mailman3 on debian bullseye
by Servizio Informatico U.I.C.I. Sezione territoriale di Brescia March 16, 2023

March 16, 2023

Hello all, I'm a blind server administrator living in Italy. I use mailman since 2010 and I was very happy for this list manager. When was released the version 3 I started to have many problems to configure it. In this days I installed a new server for my association and I have this problem that I don't know to solve. The server is a debian bullseye. I installed mailman3-full from the standard packege. I'm using nginx as web server. I configured mailman3 and mailman3-web wit https support. All is working fine, but if I attempt to subscribe someone it does not work. I send a subscription e-mail to the address list and I receive correctly the request to confirm subscription. When I reply to the request mailman log gives this error: requests.exceptions.SSLError: HTTPSConnectionPool(host='localhost', port=443): Max retries exceeded with url: /postorius/api/templates/list/listname.domain/list:user:notice:welcome (Caused by SSLError(SSLCertVerificationError("hostname 'localhost' doesn't match either of 'example.com', 'www.example.com'"))) The strange thing is that I configured a domain list.example.com and in the configuration files I put this domain. Mailman3-web works fine I can create lists and make settings. Have you an idea about this issue?

Change 'from' server for outgoing messages
by Benjamin Goldberg March 12, 2023

March 12, 2023

Hi. I'm running mailman3 on a VPS. The hostname of the VPS is not the hostname that I'm using for mailman3. The webapp is using an Apache Virtual host. I am routing outgoing emails through a third-party smtp relay. The VPS hostname is smart.bnmng.com and the mailing list hostname is 757pug.org Signup confirmation and welcome emails are working. They appear to be coming from the intended host, which is 757pug.org But emails from the mailing lists are being blocked by the smtp relay. I think it's because they are not coming from 757pug.org; They are coming from smart.bnmng.com All of the mailinglists' mail_host fields are correct, 757pug.org from mailman.cfg: incoming: mailman.mta.postfix.LMTP outgoing: mailman.mta.deliver.deliver lmtp_host: 127.0.0.1 lmtp_port: 8024 smtp_host: smtp.mailersend.net smtp_port: 587 smtp_secure_mode: starttls smtp_user: (my relay service username) smtp_pass: (my relay service password) from settings.py: DEFAULT_FROM_EMAIL = 'admin(a)757pug.org' SERVER_EMAIL = 'admin(a)757pug.org' EMAIL_BACKEND = 'django.core.mail.backends.smtp.EmailBackend' EMAIL_HOST = 'smtp.mailersend.net' EMAIL_USE_TLS = True EMAIL_PORT = 587 EMAIL_HOST_USER = (my relay service username) EMAIL_HOST_PASSWORD = (my relay service password) So it seems like mailman core is not using the mail_host field. How can I fix that? Thank you

MM2 -> MM3 Migration: listinfo page
by Odhiambo Washington March 10, 2023

March 10, 2023

I have migrated from MM2 to MM3. However, writing HTML is not one of my strengths. I need to edit my MM2 listinfo page to: a. Remove everything below the "Subscribing to LISTNAME" heading and below that add a link to the new http://WEBSERVER/accounts/signup/ which ideally should open on a new browser tab. b. Add a link to the new archives at https://WEBSERVER/archives/list/$list_id/ For those who have migrated from MM2 to MM3, does someone have an elegantly modified listinfo page they are willing to share? -- Best regards, Odhiambo WASHINGTON, Nairobi,KE +254 7 3200 0004/+254 7 2274 3223 "Oh, the cruft.", egrep -v '^$|^.*#' ¯\_(ツ)_/¯ :-)

Where to configure 'hostname' used in 'From:'-header?
by Dmitri Heerdegen March 10, 2023

March 10, 2023

Hello, I've recently installed MM3 with Exim4 on, say, subdomain.myhost.tld and configured MM3 to use lists.someotherdomain.tld as web host and mail host. Thus, the mailman.cfg contains: [mta] smtp_host: lists.someotherdomain.tld When I send a message to test(a)lists.someotherdomain.tld it gets delivered, however the 'From:'-header becomes "test(a)subdomain.myhost.tld".

Attack on Mailman Server?
by Eggert Ehmke March 9, 2023

March 9, 2023

I had some attacks on my wordpress homepage today, I added some IPs to the blacklist of my firewall. At the same time, I got several reports like this: Internal Server Error: /accounts/signup/ TemplateDoesNotExist at /accounts/signup/ 429.html Request Method: OPTIONS Request URL: https://lists.eehmke.de/accounts/signup/ Django Version: 3.2.16 Python Executable: /opt/mailman/venv/bin/uwsgi Python Version: 3.9.2 Python Path: ['.', '', '/etc/mailman3', '/usr/lib/python39.zip', '/usr/lib/ python3.9', '/usr/lib/python3.9/lib-dynload', '/opt/mailman/venv/lib/ python3.9/site-packages'] Server time: Thu, 09 Mar 2023 13:09:34 +0100 So it seems there were attempts to register new users but this caused this internal error. Where can I send the complete error message?

Permissions issue after upgrade of virtualenv
by Odhiambo Washington March 9, 2023

March 9, 2023

Ola, So I installed a new virtualenv using Python3.11, kept all settings intact, copied /opt/mailman/mmvar from the old virtualenv to the new one. Trying to access Postorius, I am greeted with this error: Thu Mar 09 22:17:59.313459 2023] [core:error] [pid 15655] (13)Permission denied: [client 197.232.xx.xx:26574] AH00035: access to / denied (filesystem path '/opt/mailman/mm') because search permissions are missing on a component of the path, referer: https://mm3-lists.kictanet.or.ke/ I did not change Apache config and I made sure that /opt/mailman is all owned by mailman:mailman. What am I missing? -- Best regards, Odhiambo WASHINGTON, Nairobi,KE +254 7 3200 0004/+254 7 2274 3223 "Oh, the cruft.", egrep -v '^$|^.*#' ¯\_(ツ)_/¯ :-)

I however looking to figure out how can I control or change settings for this particular mechanism. Please advise me. emailname(a)example.it's subscription has been disabled on listname(a)domain.eu due to their bounce score exceeding the mailing list's bounce_score_threshold. Regards, Tibor
