Mailman 3 Privacy Policies, GDPR, etc and social logins
by Jered Floyd 05 Oct '23

05 Oct '23

Greetings, I host a variety of lists for social, community, and software projects, and updated my infrastructure from Mailman 2 to Mailman 3 last year. As part of this, I enabled Django allauth modules to simplify login and management for subscribers. Recently, Facebook notified me that they would be disabling the "application" because it failed to provide a sufficient Privacy Policy. Previously I had linked the app to [ https://www.gnu.org/software/mailman/privacy.html, | https://www.gnu.org/software/mailman/privacy.html, ] but they have said: Platform Terms 4.b: Your privacy policy must comply with applicable law and regulations and must accurately and clearly explain what data you are Processing, how you are Processing it, the purposes for which you are Processing it, and how Users may request deletion of that data. During testing, we found that your privacy policy doesn’t explain how users can request data deletion. Update your privacy policy to include this information before you submit an appeal. This is a bit of a headache. Do we have a draft of a community Privacy Policy for a vanilla Mailman 3 install that meets Facebook's requirements? Is this going to be a constantly unraveling thread of future GDPR and Right to Be Forgotten troubles, since there doesn't seem to be an easy way to scrub a subscriber from Hyperkitty archives if they request so? How have others addressed this situation? Regards, --Jered

All list messages shunted due to mailman core database lock
by Ryan Curtin 04 Oct '23

04 Oct '23

Hi there, I have been trying to debug a git commit development list for a project I maintain: http://lists.mlpack.org/mailman3/hyperkitty/list/mlpack-git@lists.mlpack.or… The list is run on mailman3 as provided by Debian. Messages are successfully received---you can see all the test messages in the archives I just linked to if you want to click on it. However, no messages are actually relayed to subscribers. I spent a while digging into logs and found that every message sent to the list results in an error like this in /var/log/mailman3/mailman.log: ``` Oct 02 17:01:26 2023 (2957556) Uncaught runner exception: (raised as a result of Query-invoked autoflush; consider using a session.no_autoflush block if this flush is occurring prematurely) (sqlite3.OperationalError) database is locked [SQL: UPDATE mailinglist SET last_post_at=?, post_id=?

Most threads I have read appear to be related to the Django interface encountering a locked database, but this looks different---it seems mailman core is having the problem, not anything having to do with mailman3-web or Django. Does anyone have any thoughts on things I can do to fix this error? I am not a mailman3 expert (and to be perfectly honest I don't want to be one, I just want to post things to the list :)). One extra caveat: rebooting the machine I am using is not a realistic option. Thanks in advance for any help. Ryan -- Ryan Curtin | "Not like this... not like this." ryan(a)ratml.org | - Switch

parallel processing of out queue messages
by Dan Caballero 04 Oct '23

04 Oct '23

Hello, I have tried increasing the number of runners to alleviate a backlog of messages in the "out" queue. I increased the out runners to from 32 to 64. However, I'm not seeing a significant increase in the processing of "out" messages. I've seen at most 12 ".bak" files in the out queue after increasing the runner instances. Is there another configuration needed beyond the number of runner instances to get more messages processed at once? Thanks as always for your help! -- Dan

Postorius is not working (throws "Error 500" suddenly after changing POSTORIUS_TEMPLATE_BASE_URL and changing back)
