Filtering signed mails
by Rainer Herbst Nov. 12, 2021

Nov. 12, 2021

Dear all, today I recived a user complain that his messages were rejected with error "The message's content type was not explicitly allowed" I checked the list and indeed, it was configured to filter content and to allow only a very limited number of content types, namely application/pdf and image/jpeg. After some experiments, the problems seems to be the s/mime signature. The messages contain a signature: <snip> Content-Type: application/x-pkcs7-signature; name="smime.p7s" Content-Transfer-Encoding: base64 Content-Disposition: attachment; filename="smime.p7s" <snap> I added this type to the allowed MIME content type, but signed messages are still rejected. What do I miss?

Moderation Action Changed After Import
by Brian Carpenter Nov. 12, 2021

Nov. 12, 2021

I migrated a Mailman 2 list using import21 and the list's config.pck into a Mailman 3 list. The list owner reported back that about 98% of the list members had their moderation setting changed to Reject (with notification). He said the previous moderation was the list's default which was hold for moderation. Is such a thing possible with an import job? Is this perhaps a bug that has been reported previously? -- Brian Carpenter Harmonylists.com Emwd.com

Issues with cross posted emails after upgrading to mailman 3.3.6
by Simon Coggins Nov. 10, 2021

Nov. 10, 2021

Since upgrading from 3.3.4 to 3.3.6 we are seeing a high instance of emails that are sent to 2 lists (EG 2 campuses). One campus will get the email and the other campus will get an email that just contains "The content of this message was lost. It was probably cross-posted to multiple lists and previously handled on another list.” Is this something new in 3.3.6? I’m trying to work out what’s going on and why it would be lost. Both lists need the email as the membership list is different so the people on the second list get a useless email. -Simon --- [https://www.cqu.edu.au/] Mr Simon Coggins Principal Systems Engineer | Digital Services Directorate CQUniversity Australia, Level 6.14, 160 Ann Street, Brisbane, QLD 4000 P +61 7 3295 1182 | X 51182 | M +61 408 115 861 | E s.coggins(a)cqu.edu.au<mailto:s.coggins@cqu.edu.au> [https://www.cqu.edu.au/social-media] I respectfully acknowledge the Traditional Owners of the land on which we work and learn, and pay respect to the First Nations Peoples and their Elders, past, present and future.

outgoing.py mailman@example.com issue

I deployed Mailman3 last night and today we've had some "bounced" messages with headers referencing mailman(a)example.com. This has only happened with a few lists. Any ideas what causes this? We are using an SMTP relay server for incoming and outgoing messages in front of the Mailman3 service. Thanks!

Mailman Suite installation on CentOS 7
by Kimmo L Nov. 8, 2021

Nov. 8, 2021

Hello! I want to install fresh Mailman, which is combined with hyperkitty+postorius. After checking documentation i found, that Mailman Suite is perfect for me. But i have some misunderstandings about installation. I only found this part in documentation, which explains how to clone and start using Mailman Suite (https://docs.mailman3.org/en/latest/devsetup.html#run-the-mailman-suite-com…) But am i correct, that before doing so, i need to install mailman core, mailman client, django-mailman3 ? Or what would be the correct steps to build up my first Mailman Suite on CentOS? Br, Kimmo

Showing sender as ... via ... list
by Wolfgang Bock Nov. 8, 2021

Nov. 8, 2021

Hello, after correcting little discrepancies within the mm3 configuration proposals in the debian buster package and the help of Mark I am very pleased with it now. BTW: There is a very helpfull instruction for installing other mail components like dovecot/postfix/etc on https://workaround.org/ispmail/buster/ actually not yet for bullseye, but my experience is: it will come soon. So I dont understand the discussions like: "hands off debian mm3 packages". Here is my question: What do I have to configure to get my lists to show the sender like in this list: Wolfgang Bock via Mailman-users mailman-users(a)mailman3.org <mailto:mailman-users@mailman3.org> I tried several combinations but failed upto now. Can someone help?? Regards Wolfgang

Re: mailman3 postorius cannot retrieve template
by Wolfgang Bock Nov. 5, 2021

Nov. 5, 2021

Dear Mark, you wrote: "When you create a template in Postorius, that uri becomes something like `https://example.com/mailman3/api/templates/list/<list_id>/<template_name>` which basically says get the template from Postorius, and the template if any in var/templates is ignored." In my case that is not true. I get an db-entry in the mailman3 table template which doesnt lead to a suitable link: https://localhost/postorius/api/templates/list/testliste01.mydomain.de/list: member:regular:footer In the next stept it leads to a flood of entries in my syslog because django is asking for a certificate match for "localhost": Nov 2 11:47:49 myserver mailman3[175334]: Nov 02 11:47:49 2021 (175334) Certificate did not match expected hostname: localhost. Certificate: ... Letsencrypt cannot deliver this match for "localhost", it is impossible to configurate letsencrypt to do so. The running script must create a postgres INSERT database command which includes the correct domain-name including the correct path .../mailman3/api/templates .... and not ... postorius/api/.... I dont know, where is the place to correct this. - in mailman-web.py ?? ... ALLOWED_HOSTS ... '*' or MAILMAN_REST_API_URL = 'http://localhost:8001' or POSTORIUS_TEMPLATE_BASE_URL = 'https://localhost/mailman3/' - in mailman.cfg ?? the [paths.debian] section the [webservice] section - or elsewhere Thanks in advance for your reply.

By default Mailman searches for templates first in the var/templates directory and then in the templates directory in the Mailman installation. The details are described at https://gitlab.com/mailman/mailman/-/blob/master/src/mailman/utilities/i18n. py#L44. However, the default search is only applied if there is matching entry for the template name and context in the `templates` table in the database or if the uri in the entry is a `mailman://` uri. When you create a template in Postorius, that uri becomes something like `https://example.com/mailman3/api/templates/list/<list_id>/<template_name>` which basically says get the template from Postorius, and the template if any in var/templates is ignored. > In the sys.log I found the following error message: > Oct 29 11:28:04 myserver mailman3[33015]: Message: 'Cannot retrieve > template at > http://localhost/postorius/api/templates/list/testliste01.mydomain.de/ > list:m ember:regular:footer (<no authorization>)' So Mailman is trying to get the Postorius template.

mailman3 admin from mailman2 & File location questions
by bob B Nov. 4, 2021

Nov. 4, 2021

Question1 We use help users with list settings, so we would log into mailman2 with the master password. So what is the best way to duplicate this for mailman3. I assume I can just use the admin account and share that password with my other admins. But I see the domain owners, but is that working? I added someone as a domain owner, and they do not see private email lists and it looks like that can not edit any list settings? There was a post that this had not yet been implemented? Any other options? Question2 Where are all the emails/archives stored? are they in /opt/mailman/...., or are they in the database? For mailman2 we had mailman located on a large volume to handle archives, just trying to see if that is the same for mailman3 or if all the data is now in the database (which will be external for our installation)?

Current status and issue deleting Archives in Mailman3
by bob B Nov. 3, 2021

Nov. 3, 2021

So just want to make sure I have the latest information after searching this list and googling or have I missed something? It appears there is no way in mailman3 to delete archives. There has been discussion on implementing this, but it has not been developed? is that correct? I saw references to: >>> from hyperkitty.models import MailingList >>> ml = MailingList.objects.get(name="test2(a)freeculture.org") >>> ml.delete() But how do I run this? I believe it is run in mailman-core (I am in a docker environment but that should not matter). I can get into the mailman shell, but that command does not work I did the following: bash-5.0# mailman shell Welcome to the GNU Mailman shell Use commit() to commit changes. Use abort() to discard changes since the last commit. Exit with ctrl+D does an implicit commit() but exit() does not. >>> from hyperkitty.models import MailingList Traceback (most recent call last): File "<console>", line 1, in <module> ModuleNotFoundError: No module named 'hyperkitty' >>> What am I missing? ************** Question 2 What about pruning archives? I use to run a script for mailman2 to prune archives of messages older than X days for a list, Is that possible in mailman3

Mailman notify generating emails for request that aren't visible.
by Simon Coggins Nov. 2, 2021

Nov. 2, 2021

Hi, We’re running mailman 3.3.4 (about to upgrade to 3.3.5 this week). I enabled mailman notify cron a few weeks ago to email out any pending requests for admins. I’ve now got multiple lists that keep emailing out the same outstanding holds but they can’t visible in the GUI. The requests are all duplicates as well. This is a redacted example email: -----Original Message----- From: mailman-alerts(a)example.com<mailto:mailman-alerts@example.com> Sent: Monday, 1 November 2021 8:10 AM To: somelist-owner(a)lists.example.com<mailto:somelist-owner@lists.example.com> Subject: The somelist(a)lists.example.com<mailto:somelist@lists.example.com> list has 4 moderation requests waiting.
