Thank you both for the help. I have SPF and reverse DNS setup. But I thought DKIM is no help because Mailman rewrites the email headers?

mailman3 does not send to the members of the lists
by maszap＠tin.it 12 Jul '20

12 Jul '20

Goodmorning everyone, I'm setting up a mail server to manage a mailinglist. I installed mailman3-full and configured everything. I can create a list, add members to the list, but when I create a new thread, I only get it on the email from the same domain as the list. While all the other members of the list, they do not receive the thread. I tried to check the logs, but I don't see anything significant. What can I check? Thank you in advance Max

Mail control not given from Mailman 3 to postfix
by Shashikanth Komandoor 12 Jul '20

12 Jul '20

Hi Team, I am currently running Mailman 3 with version 3.3.1 and in built postfix version 2.10.1-6 on RHEL 7.5 in production environment from the past 2 months almost. Recently I observed a peculiar case. There is a list say testlist(a)lists.testdom.com has a non member say testuser(a)testdom.com whose Moderation attribute is set to "Accept immediately (bypass all other rules). This testuser(a)testdom.com has sent a mail to testlist(a)lists.testdom.com and postfix of my Maliman 3 received the request and handed over to Mailman at 0.0.0.0:8024 socket running on the same machine and the same is logged in /var/log/maillog. Since the user has the moderation attribute set to Accept, the /var/lib/mailman/mailman/var/logs/vette.log also displayed "ACCEPT" on searching with the same message id. At this point, to my expectations, there should be 2 entries for this message id in smtp.log one for smtp and one for post. But I don't find any log records with this message id in smtp.log and of course the mail is not delivered even. Could you please help me out if I have missed any point or improperly understood the mail flow while using the mailman 3? Please also let me know if I need to see any more log files for tracing the issue. -- Thanks & Regards, Shashi Kanth.K 9052671936 <https://www.avast.com/sig-email?utm_medium=email&utm_source=link&utm_campai…> Virus-free. www.avast.com <https://www.avast.com/sig-email?utm_medium=email&utm_source=link&utm_campai…> <#DAB4FAD8-2DD7-40BB-A1B8-4E2AA1F9FDF2>

ARC
by David Krantz 11 Jul '20

11 Jul '20

Hi, A completely different question: Is there anyone that has a working non-naive setup for ARC signing of mail list mail in mailman? I've tried both the built-in version but it was not usable in the version I tried for the case where there are several domains with different selectors and keys and where the outgoing mail also is DKIM-signed. This might be that the documentation is lacking but a very shallow look in the source gave me the impression that the implementation is limited to one domain which is not enough for my use case as I have lists in several domains. I use DKIM on outgoing mail with a setup where each domain has its own keys and selectors. As discussed here earlier, the DKIM signature should be added before the ARC signature. I have tried to use rspamd after a tip here for this but without luck so far, but this is somewhat off topic for mailman although related of course. rspamd seems very good for other purposes and solves my other problems with greylisting, DKIM-signing and spam filtering. That said, ARC seems difficult to get to work for forwarded mails there also... cheers // David

Update a member's display_name
by Nick Wynja 08 Jul '20

08 Jul '20

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 08 Jul '20

08 Jul '20

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 07 Jul '20

07 Jul '20

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 06 Jul '20

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 04 Jul '20

04 Jul '20

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?
