migrate MM3 list from an old server to a new one
by noc＠iem.at Aug. 8, 2024

Aug. 8, 2024

hi all, i have an old mailman3 instance (3.2.1), and would like to migrate it's lists and archives to a new instance (3.3.8) on a different host. for various reasons, i don't think i am able to upgrade the old instance in-place. unfortunately, i haven't found any documentation on how to proceed. there *is* documentation about migrating MM2 to MM3; and my understanding is that `mailman-web migrate` can be used to upgrade a given MM3 instance to a new version. but how can i export an entire MM3 list (including 20 years of archives) to some serialization format, and import it again in another instance? thanks for your help. gamsr4e IOhannes PS: (again) I'm resending this message, as the one i sent yesterday seems to have vanished (i *did* check the archvies). i have no clue why this happens, as i can post via the webinterface just fine (only when using my trusted MUA they just vanish).

Header settings and Gmail
by erik＠dante.de Aug. 7, 2024

Aug. 7, 2024

Hi, We operate a mailing list on which many members use their Gmail address. In the default settings, this results in a warning and delayed delivery (and maybe marking as spam): status=deferred (host gmail-smtp-in.l.google.com[74.125.128.27] said: 421-4.7.28 Gmail has detected an unusual rate of unsolicited mail. To protect 421-4.7.28 our users from spam, mail has been temporarily rate limited. For 421-4.7.28 more information, go to 421-4.7.28 https://support.google.com/mail/?p=UnsolicitedRateLimitError to 421 4.7.28 review our Bulk Email Senders Guidelines. As a preventive measure, it helps to use DMARC mitigation action with “Replace From: with list address” and “ DMARC Mitigate unconditionally ”. But now some users are unhappy with the From header " Username via Test-liste <test(a)test-liste.org>". They would rather have their email address in it. Is there a solution with which Google delivers the mailing list messages without complaining, but the sender email address is also in the “From:”? Thanks Erik

Only Recent archive tab works after mailman upgrade
by zoltan＠circle-interactive.co.uk Aug. 6, 2024

Aug. 6, 2024

Hi, since I upgraded mailman to 3.3.9 (python 3.11.2) I have an odd issue on lists' archive page. Apparently only the Recent tab works. If I switch to Active or Popular I see the change in the url but page content does not refresh. I can not see any errors in browser console and in logs so I am quite clueless how to debug further :( Thanks for the ideas.

Where to put static files referred to from list Info page?
by Greg Newby Aug. 6, 2024

Aug. 6, 2024

Hi friends. Some of my version 2.1 lists had some static files that were referenced from the list's HTML pages. I'd like to do the same for the lists now that they're ported to MM3. My question: Is there a place I can put these files within the Mailman directory hierarchy so they can be linked from the list Info page? I.e., under "Settings / List info / Long description" I'd like to include a <a href=...> to a file that's somewhere in a persistent location in the same directory tree as the Mailman web. I tried putting it under mm/var/lists/listname/ (where 'listname' exists, and is where templates go. This yielded a '404.' I confirmed I can add an href to the Long description, but don't know where in the Mailman3 directory hierarchy I can put the files. Thanks! Greg Newby

External MTA incoming mail: configuration
by Roland Giesler Aug. 6, 2024

Aug. 6, 2024

I have mailman set up to send mail via an external MTA, which is supported by mailman and described in the documentation here: https://docs.mailman3.org/projects/mailman/en/latest/src/mailman/docs/mta.h…. Specifically it says: |lmtp_host|and|lmtp_port|are parameters which are used by Mailman, but also will be passed to the MTA to identify the Mailman host. The “same host” case is special; some MTAs (including Postfix) do not recognize “localhost”, and need the numerical IP address. If they are on different hosts,|lmtp_host|should be set to the domain name or IP address of the Mailman host.|lmtp_port|is fairly arbitrary (there is no standard port for LMTP). Use any port convenient for your site. “8024” is as good as any, unless another service is using it. However, there is a practical problem with LMTP (to receive incoming email) which is as follows: The setup in mailman.cfg: lmtp_host: lists.fast.za.net lmtp_port: 8024 Now, lists.fast.za.net is the mailman server. The docs say that mailman passes these on to the MTA. However, the MTA (postfix) on box2.gtahardware.co.za has the following setting in it main.cf: virtual_transport=lmtp:[127.0.0.1]:10025 If I reply to a signup confirmation email for example, the mail is received and processed by box2.gtahardware.co.za, and it is not passed on to the mailman server. So what is meant by "but also will be passed to the MTA to identify the Mailman host" in the docs? If I change the config of the MTA (postfix) to be "virtual_transport=lmtp:[lists.fast.za.net]:8024", I assume the incoming mail will be forwarded, but how does postfix know that only the mailman emails should be forwarded and not all the other mail that the server at box2.gtahardware.co.za receives? This is quite fuzzt to me at this stage. Could someone help me with some clarity please?

Create a mailman-web admin user
by Roland Giesler July 30, 2024

July 30, 2024

I having a hard time understanding how to create an admin user for postorius (mailman-web). The docs say at https://docs.mailman3.org/en/latest/config-web.html Setting up Admin Account <https://docs.mailman3.org/en/latest/config-web.html#setting-up-admin-account> To create a superuser account in Django, run the following interactive command as|mailman|user: (venv)$ mailman-web createsuperuser However, which user in the mailman user mentioned? I tried to do this as root, but login in as an admin doesn't give me any option to create new lists in postorius. What am I missing / doing wrong? regards Roland

using SSH/TLS with external MTA
by Roland Giesler July 30, 2024

July 30, 2024

I have managed thus far to get things working on my new install, but I need to use a secure logon to send mail from an external MTA. I have set up: /etc/mailman/mailman.cfg: smtp_host: box2.gtahardware.co.za smtp_port: 465 smtp_user: roland(a)giesler.za.net smtp_pass: <hidden> smtp_secure_mode: smtps smtp_verify_cert: no smtp_verify_hostname: no I'll get a cert installed later, for now just want to get it going. This error occurs when I try to create a new user in postorius.

xapian db corruption - xapian.DatabaseCorruptError: Couldn't read enough (EOF) ??

Today, my hourly cron job has generated an error and continues to do so every hour: ``` Subject: Cron <mailman@gw> /opt/mailman/mm/bin/django-admin runjobs hourly ``` Not sure what caused this.

Internal Server Error, Need 2 values to unpack in for loop; got 1
by Elias Rudberg July 29, 2024

July 29, 2024

Hello! I am using mailman3 (version 3.3.8) and it mostly works fine, but sometimes (usually several times every day) the error below appears. Any suggestions for what could be done about this? Should it be considered a bug in Django, so not a mailman3 problem, or does it indicate something wrong with mailman3 itself? Best regards, Elias Here is what the error message looks like: ------------------------------------------- [Django] ERROR (EXTERNAL IP): Internal Server Error: /mailman3/postorius/lists/ Internal Server Error: /mailman3/postorius/lists/ ValueError at /postorius/lists/ Need 2 values to unpack in for loop; got 1.

MM3 generates long lines?
by peter＠chubb.wattle.id.au July 28, 2024

July 28, 2024

I'm seeing emails being dropped when mm3 talks to the local smtp server, with log errors like: 2021-06-23 15:42:24 1lvvea-007r8u-VN H=localhost (<FQDN>) [::1] F=<announce-bounces@<FQDN>> rejected after DATA: maximum allowed line length is 998 octets, got 1036 The email itself did not have such long lines AFAICT. I can disable line length checking on the mailserver, but that sounds like a recipe for the next one along to drop the email. Peter C
