Update a member's display_name
by Nick Wynja July 8, 2020

July 8, 2020

Hi all, I want to update some list member's display_name either with mailman shell or mailmanclient. These mostly aren't users in Postorius so I only want to operate on the subscribed list member. I've tried everything I can find in the docs and am stuck. I've tried using `user_manager.get_user()` and then updating `user.display_name` followed by a `commit()` but it doesn't seem to persist the change. The `absorb_existing` flag for mailmanclient's `User.add_address()` looks promising but the docs read "It will import the existing user into the current one, not overwriting any previously set value." which in some cases, the member already has a display_name set. I haven't tried this yet. I'd appreciate any help pointing in the right direction. Thanks, Nick

Bounce handling after upgrade
by David Krantz July 8, 2020

July 8, 2020

Hi, I am in the process of configuring a new mailman3 server based on my old one. This includes upgrading to the latest version of mailman and installing a database upgrade. To my surprise mailman core started by sending tens of mails and blocking the corresponding users for very old bounces. What is worse is that this happens every time I start mailman core. Now I have blocked (almost) all outgoing mail in postfix using a transport map which discards it but this is a temporary testing measure of course. When I deploy this server into production, I do not want these recipients to be blocked as the old problems have been solved since very long. My plan is to reload the database from a newer backup anyway... Would it be enough to empty the bounce table (bounceevent) or is there anything else driving this behaviour? Or is there a better way to do this via the mailman shell? For me a "delete from bounceevent" seems a lot simpler than anything via the shell but there may be dependencies in the database. Cheers // David

Importing list archives
by Mark Dadgar July 7, 2020

July 7, 2020

So I got a shiny new instance of Mailman3 installed (thanks Brian!). I recreated my lists and I am now importing large historical list archives from an mbox file (24GB). It takes a couple of hours to run this import, so I killed the import task after about 20 minutes so I could restart it in a screen session. Now when I restart the import, it finishes almost immediately: (venv) mailman@mail:/opt/mailman/mm$ /opt/mailman/mm/bin/django-admin hyperkitty_import -l trackjunkies(a)pdc-racing.net trackjunkies.mbox Importing from mbox file trackjunkies.mbox to trackjunkies(a)pdc-racing.net Computing thread structure Synchronizing properties with Mailman Warming up cache The full-text search index is not updated for this list. It will not be updated by the 'minutely' incremental update job. To update the index for this list, run the Django admin command with arguments 'update_index_one_list trackjunkies(a)pdc-racing.xn--net-to0a. (venv) mailman@mail:/opt/mailman/mm$ Which is clearly not correct. Anyone have an idea on how to restart this import? THanks! - Mark ----- mark(a)pdc-racing.net | 408-348-2878

Error after HyperKitty 1.3.x upgrade
by Florian Schulze July 6, 2020

July 6, 2020

Hi! After upgrading to HyperKitty 1.3.x I get the following error for qcluster: File ".../lib/python3.7/site-packages/django_q/cluster.py", line 300, in pusher task = SignedPackage.loads(task[1]) File ".../lib/python3.7/site-packages/django_q/signing.py", line 31, in loads serializer=PickleSerializer) File ".../lib/python3.7/site-packages/django_q/core_signing.py", line 38, in loads return serializer().loads(data) File ".../lib/python3.7/site-packages/django_q/signing.py", line 44, in loads return pickle.loads(data) AttributeError: Can't get attribute 'process_task_result' on <module 'hyperkitty.tasks' from '.../lib/python3.7/site-packages/hyperkitty/tasks.py'> How do I recover from that? It seems like there are still persisted tasks in the qcluster queue using the old code from 1.2.x with the old locking implementation. Regards, Florian Schulze

Using external services for deliverability?
by tom＠gather.coop July 4, 2020

July 4, 2020

I have a Mailman 3 server up and running but I'm terrified to migrate to it from my existing Mailman 2 provider for fear that services like Gmail will randomly start blacklisting my IP with little I can do about it. I have SPF records set up so I'm hoping I'll be Ok but I'd like to have a backup plan. Has anyone ever tried using an external service like Mailgun or Sendgrid as a relay? I tried both but couldn't get either to work due to their sender authentication mechanism. They want all 'From:' headers to be from domains that are pre-authenticated as senders. But Mailman keeps the 'From' header from the original sender so it won't match any authenticated domains. Right? Is there anything to be done here or do I just have to migrate and pray?

Example Logrotate files for Mailman3
by Andrew Hodgson July 3, 2020

July 3, 2020

Hi, Does anyone have any usable Logrotate files for Mailman3 (especially for the web stuff)? Will look to create my own if no one comes forward but if anyone has anything they are willing to share it would be fab. Thanks. Andrew.

hidden list is hidden even to the owner
by Mohsen Masoudfar July 2, 2020

July 2, 2020

Hi, I am not sure, if it is designed this way, or I am doing something wrong. I created a list in MM3 as a hidden list, meaning: Show list on index page: NO and assigned the owner. When I login as Postorius web admin, I see the list on the list page which is listed as: (unadvertised*). This is fine. But when the owner or moderator login to Postorius they don't see the list at all. Of course if they add the list name at the end of the URL, they get to the list and as the owner can manage it too. My question is: I am just not sure, if I am missing something or this is how it is supposed to work? You could expect, that the owner or the moderator should see the list as (unadvertised*) too.
