Performance issues with Mailman 3
by Wong, Wesley Oct. 8, 2022

Oct. 8, 2022

Hi, I am having some performance problems with Mailman 3 (version 3.3.5) when it sends out a lot of messages to people. We recently migrated from our old Mailman 2.1.x system to Mailman 3.x about 3 months ago. We host about 350 lists with membership counts varying between 10 to 1500 members on some of the lists. I noticed that outbound messages from Mailman to our outbound SMTP are getting delayed up to an hour when Mailman is processing a lot of messages going to lists. I was wondering if there are good performance tuning tips to be considered for Mailman 3 (i.e. OS, database and/os Mailman Core). I am running the setup on a VM. Here is my configuration for VM and OS: VM config: ESX 6.7 (CPU: Intel(R) Xeon(R) Gold 6242) 4 CPU 8 GB SLES 15 SP3 Python 3.9.10 MariaDB 10.5.17 Mailman 3.3.5 Thanks. wesley Wesley Wong Senior Systems Engineer Anderson Computing & Information Services | ACIS 310-206-2571 [ucla-logo---new_smaller] ___________________________________________ Mailman's content filtering has removed the following MIME parts from this message.

Mailman2 CLI commands for Mailman3
by Dave Hall Oct. 5, 2022

Oct. 5, 2022

Hello. Sorry if this is an old topic. I'm in the process of migrating from 2.1 to 3.2. In my use case one of the advantages of Mailman 2.1 vs services like Google Groups has been the ability to manage lists from the command line. Things like using sync_members to update the list for a committee when the membership of the committee is updated one a year, or like using find_members and remove_members to remove a user from all mailing lists when they leave the organization. Even the ability to script mailing list creation. So far I haven't found these commands in Mailman3. I hope there is a plan to add these soon. Thanks. -Dave -- Dave Hall Binghamton University kdhall(a)binghamton.edu

Django site - how to create programmatically - new install
by daniel.botting＠codethink.co.uk Oct. 3, 2022

Oct. 3, 2022

Hi all, I've mainly setup mailman3 to replace our mailman 2.1 install using Ansible, a point I could do with some assistance on is setting the fqdn used programmatically. I've been doing alot of reading before creating this thread. To create a domain I currently navigate to: https://serverfqdn.com/postorius/domains/ and click 'Add Domain'. I believe this is setting the name of the Django site, please accept my apologies if I'm wrong and the SITE_ID=1 is then used, I am only planning to use one domain only. I'm using Postgres and when I check the contents of the Django_mailman3_maildomain table as below afterwards: mailman3web=# TABLE django_mailman3_maildomain; id | mail_domain | site_id ----+--------------------------------------+--------- 1 | mailman3-test2.guest.codethink.co.uk | 1 Many thanks Daniel

Upgrade Mailmam Core from
by sascha.rissel＠gmail.com Oct. 3, 2022

Oct. 3, 2022

Hello, I have newly set up Mailman 3 on Ubuntu 20.04. Sending and receiving mails between list members does work, but I am currently experiencing two issues: 1) a lists non-members who send mails to the list don't get notified about the message being held for moderation. Moderation itself doesn't seem to work. The moderation list is always empty. 2) Archiving is activated within list settings, but there isn't any archive created. I found this thread, where the first of these issues is also described: https://lists.mailman3.org/archives/list/mailman-users@mailman3.org/thread/… Here there is an incompatibility between Mailmain 3 and Python depicted, which also seems to affect me. I am running Mailman 3.2.2 on Python 3 .8.10. So I need to either upgrade Mailman Core or downgrade Python. I already did > apt-get upgrade > apt-get update Unfortunately this didn't upgrade Mailman Core's version. Which steps do I have to undertake to upgrade Mailman Core? Regards, Sascha.

All addresses in a bounced list posting seem to be considered as bouncing
by Andy Smith Oct. 1, 2022

Oct. 1, 2022

Hi, I noticed this happened (bounce.log): Jul 09 12:46:51 2022 (71506) Member xxxxx(a)xxxxx.force9.co.uk already scored a bounce on list users.mailman.bitfolk.com today. Jul 09 12:46:51 2022 (71506) Bounce message for a non subscriber: Email users-leave(a)mailman.bitfolk.com is not a subcriber of users.mailman.bitfolk.com Jul 09 12:46:51 2022 (71506) Member andy(a)bitfolk.com on list users.mailman.bitfolk.com, bounce score = 1. Jul 09 12:46:51 2022 (71506) Bounce message for a non subscriber: Email users(a)mailman.bitfolk.com is not a subcriber of users.mailman.bitfolk.com What happened here is that a reply to one of my posts was rejected by subscriber xxxxx(a)xxxxx.force9.co.uk at smtp time (Exim mainlog): 2022-07-09 12:46:13 1oA9qc-007qOx-0T ** xxxxx(a)xxxxx.force9.co.uk R=dnslookup T=remote_smtp H=mx.avasin.plus.net [212.159.8.200] X=TLS1.2:ECDHE_X25519__RSA_PSS_RSAE_SHA256__AES_256_GCM:256 CV=yes DN="businessCategory=Private Organization,jurisdictionOfIncorporationCountryName=GB,serialNumber=03279013,C=GB,L=Sheffield,O=Plusnet plc,CN=mx.avasin.plus.net": SMTP error from remote mail server after end of data: 552 Spam Message Rejected The message contained my email address (andy(a)bitfolk.com) in quoted text, since it was a reply to a message of mine, and also contained addresses from the list's footer, which accounts for the log messages about users-leave(a)mailman.bitfolk.com and users(a)mailman.bitfolk.com. I'm concerned that Mailman seems to have scored my address as bouncing even though it isn't, merely because it appears inside a message that was rejected. Is that expected? Is there any way to avoid it? I see that Mailman has a bunch of heuristics to parse bounce messages. In this case though, there shouldn't have been a bounce message received to users-bounces@, as this was an SMTP-time rejection. Mailman seems to have parsed addresses out of the actual mail it was sending, rather than only scoring the subscriber address it was trying to send a list posting to. Cheers, Andy

Help addressing some issues with mailman 3 docker images
by Clark Boylan Oct. 1, 2022

Oct. 1, 2022

Hello, Some of us at opendev.org are looking to migrate to mailman 3 for our list servers. We've got about 98% of things sorted out using maxking's docker images (thank you for publishing those along with excellent documentation). There are however a small number of things that we've run into that we'd like to address before we take this to production. * Mailman 3 relies on lynx to convert html email to txt email. Lynx isn't currently installed in the docker images, but I've pushed a PR to add it to the images. https://github.com/maxking/docker-mailman/pull/552 * There are some user and group inconsistencies between the images. Not a deal breaker, but would be good to understand if these are intentional or if they can be changed without massively impacting people. https://github.com/maxking/docker-mailman/issues/550 * Issues with ALLOWED_HOSTS settings making assumptions about the environment and its inputs. We've worked around these by bind mounting in our own settings.py with these problems addressed, but it would be good to address them in case anyone else has run into this too. Details in these github issues: https://github.com/maxking/docker-mailman/issues/548 https://github.com/maxking/docker-mailman/issues/549 Ideally we'd avoid forking the images downstream and modifying them ourselves, but it seems the docker image repo is not getting a ton of attention recently. Totally understand that this may not be the biggest priority. We're happy to help address these by writing fixes and sending pull requests, but guidance would be appreciated before we head too far down that road. Once again thank you for the great documentation and images. They have already gotten us most of the way to production and the issues we've found are relatively minor. Clark

serving /static-content within /mailman3-web-Folder - change in recent mm release
by Stefan Bauer Sept. 30, 2022

Sept. 30, 2022

Hi Folks, during our migration to latest MM we noticed, that nowadays, the static content is not served from within mailmans base directory, but from outside. old MM3: domain.tld/mailman3/static/django-mailman3/js/main.js new MM3: domain.tld/static/django-mailman3/js/main.js Is there a chance to change it to the old behavior? We are running an additional nginx-proxy in front of mailman-server and dont want to forward /static, but only /mailman3. Thank you.

Sept. 29, 2022

Greetings, We will be (temporarily) splitting our single postfix instance and running two separate instances on our email server. Can we configure mailman to listen to one of them and send to the other? If so, please do direct us towards how we would go about configuring mailman to do this. versions: mailman: 2.1.15-30.el7_9.2 postfix: 2.10.1-9.el7 (both via rh/centos repo(s)) thanks so very much for any assistance/direction you're able to provide, ~c -- Charlie Derr Director of Instructional Technology Bard College at Simon's Rock https://simons-rock.edu Encryption key: http://hope.simons-rock.edu/~cderr/ 413-528-7344 Pronouns: he/him/his

HI folks, latest mm3, when starting a new thread via mm3-webinterface -> Archives -> select List -> Start a new thread. It creates the thread with _my own_ personal address. How can i set the "sender" address as the list-address? IIRC with an older mm version, it had a different behavior. Any help is greatly appreciated. thank you. Stefan

what process creates webui tables (mailmanweb db)?
by tflatley＠gmail.com Sept. 27, 2022

Sept. 27, 2022

hello again, running a venv installation i think the tables in 2 databases (mailman/mailmanweb) were initially created by running mailman-web migrate - this wrapper is not available in a package install - so i think i need to run something like this after editing my settings.py file python3 manage.py migrate Operations to perform: Apply all migrations: account, admin, auth, contenttypes, django_mailman3, django_q, hyperkitty, postorius, sessions, sites, socialaccount Running migrations: No migrations to apply. Your models have changes that are not yet reflected in a migration, and so won't be applied. Run 'manage.py makemigrations' to make new migrations, and then re-run 'manage.py migrate' to apply them. i do see tables in the mailman db but mailmanweb is empty - is there a different flag i need to run to seed the mailmanweb db? Thanks

Hi, I am running Mailman3 on Debian 11 with Apache and MariaDB. Single installation. When I edit a footer from the WebUI templates, it doesn't show in the messages. Could it be an issue with the related DB? If so - what do I need to change? Many thanks in advance for any leads! Chris

invalid parameter response of the rest-api
by Jacob Sievert Sept. 22, 2022

Sept. 22, 2022

Hello, Since a few days we get an error response from our automated membership script. We use the following code to control the membership for some lists: ``` def mailinglist_manage(list_address, members): """ make sure all 'members' are present on the list and no remove everyone else list_address : mail address of mailing list to manage addresses : mail address that are supposed to be on the list """ print("[*] update subscriptions for {}".format(list_address)) ml = mmc.get_list(list_address) # make sure we dont spam users ml.settings['send_welcome_message'] = False ml.settings.save() addresses = set(members.keys()) ml_members = ml.members ml_addresses = set((x.address.__str__() for x in ml_members)) for addr in ml_addresses - addresses: print("unsubscribe {} from {}".format(addr, list_address)) ml.unsubscribe(addr) for addr in addresses - ml_addresses: print("subscribe {} to {}".format(addr, list_address)) ml.subscribe(addr, members[addr], pre_verified=True, pre_confirmed=True, pre_approved=True) ``` Since Tuesday without any update performed by us we get the following error from the script when it's running: ``` Traceback (most recent call last): File "./mail_user_control.py", line 423, in <module> mailinglist_manage("XXX(a)EXAMPLE.COM", members) File "./mail_user_control.py", line 412, in mailinglist_manage pre_verified=True, pre_confirmed=True, pre_approved=True) File "/root/.local/lib/python3.6/site-packages/mailmanclient/restobjects/mailinglist.py", line 339, in subscribe response, content = self._connection.call('members', data) File "/root/.local/lib/python3.6/site-packages/mailmanclient/restbase/connection.py", line 112, in call error_msg, response, None) urllib.error.HTTPError: HTTP Error 400: Invalid Parameter "subscriber": . ``` If you have an idea why that code now returns this. I would be thankful. regards Jacob Sievert

Help understanding why some users don't receive emails
by Stephen Daniel Sept. 22, 2022

Sept. 22, 2022

Mailman3 people --- I'm a novice at running mailman, so any advice would be appreciated. I manage a few small lists using a mailman3 server. A few of my users complain they do not receive emails. Looking at one user in particular, I see in /var/log/syslog that postfix is sending the email. There is nothing in bounce.log. They are the only user who uses that particular email domain (embarqmail.com ). Is there anything I can do to debug why they do not get the emails? Or is this up to them and their email provider? Thanks! -- Steve Daniel

Hyperkitty displaying example.com

Sept. 22, 2022

Hi On a new installation I'm seeing "example.com" displayed at the top of the HyperKitty pages. I was expecting to see "lists.mydomainname.com", so I think I've missed something somewhere. Also, when a user signs up, the confirmation email reads as: ////////////////////////// SUBJECT: [example.com] Please Confirm Your E-mail Address FROM: postorius(a)lists.mydomainname.com BODY: Hello from example.com! You're receiving this e-mail because user yogibear has given your e- mail address to register an account on example.com. To confirm this is correct, go to https://lists.mydomainname.com/mailman3/accounts/confirm-email/NQ:1obAI3:Yw… Thank you for using example.com! example.com ////////////////////////// Any clues greatly appreciated.

How to delete non-users
by Allan Hansen Sept. 17, 2022

Sept. 17, 2022

Hi all, This is a bit of an emergency: I am getting a bunch of complaints from potential list members of my lists that they can't subscribe and they don't get messages. Apparently, the issue is that they are non-members. I have never created any non-members but looking at the docs it seems that if someone sends a message to the list, they automatically become non-members. For individuals I have been able to delete their non-membership and they then could subscribe properly. I have looked at some of my most popular lists and they have hundreds of non-members! It will take me an awful amount of time to remove each one manually, and not doing it - handling each as they complain - is also a lot of waste of time and cause of frustration for all involved. I have tried scripting it with delmember, but it does not take the '-r nonmember' option ('findmember' does!). Can anyone help me find out how to a. delete all non-members of all my lists b. prevent MM3 from creating new non-members in the future (so I don't have to keep removing them) Any help with this is appreciated. Yours, Allan I'm still at Mailman Core Version GNU Mailman 3.3.3 (Tom Sawyer) Mailman Core API Version 3.1 Mailman Core Python Version 3.7.3 (default, Jan 22 2021, 20:04:44) [GCC 8.3.0] My system used to be kept up to date by EMWD, but since Brian died have not been able to get it updated, and I'm too scared (from my attempts at installing MM3) to attempt it myself. If the above can only be solved via an update, I'd appreciate a referral.

Hi all, Not sure why, but messages set to be held for moderation are appearing to be discarded. I've tried creating a new test list, adjusting settings at the user and list level, but when a user sends a message that should be held for moderation, nothing happens. smtp.log shows the message is going through but it doesn't get to the moderation queue.

Message-Footer after migrating to Mailman3
by christopher.claus＠tgcamberg1848.de Sept. 13, 2022

Sept. 13, 2022

Hello together, I migrated a number of lists from mailman2 to mailman3 using the import functionality. Everthing works fine and the new lists are in use. Currently I´m using the maxking-docker-images with postorius: Mailman Core Version GNU Mailman 3.3.3 (Tom Sawyer) Mailman Core API Version 3.1 Mailman Core Python Version 3.8.5 (default, Feb 19 2021, 09:27:16) [GCC 9.3.0] After this migration I started a refactoring with the list-styles specially with message-footers. Already the old lists in mailman2 were confused in some configuration details an I was clear to import this "misconfiguration" and clean it up afterwards. But this was much more difficult than expected: some lists are using a footer (from the mailman2-config) and there is no record in the template-section visible. Further I found no configuration item which points to this "old" footer. I found the file [code] /usr/lib/python3.8/site-packages/mailman/templates/de/list:member:generic:footer.txt [/code] which includes the old footer: [code] _______________________________________________ $display_name Mailingliste -- $listname Zur Abmeldung von dieser Mailingliste senden Sie eine Nachricht an ${short_listname}-leave@${domain} [/code] but no configuration item to disable this behaviour. I created a new template list:member:regular:footer for the list to override the footer. But the old footer is still used - in detail: the resulting message sent to all subcribers of the list contains only the footer and the content sent to the list is an attachement of that "footer-message". This is the basic reason why I want to change it. In the logfiles I found an error and a warning: [code] ERROR 2021-05-24 16:22:22,895 1648 django.security.DisallowedHost Invalid HTTP_HOST header: 'tgc_mailman_web:8000'. The domain name provided is not valid according to RFC 1034/1035. WARNING 2021-05-24 16:22:22,896 1648 django.request Bad Request: /postorius/api/templates/list/homepage.gruppe.tgcamberg1848.de/list:member:regular:footer [/code] Obviously I have a problem with the hostname. I set [code] POSTORIUS_TEMPLATE_BASE_URL=http://tgc_mailman_web:8000 [/code] where tgc_mailman_web is my container name. This URL ist stored in the DB-table "template" for the name=list:member:regular:footer. A call to my fqdn or to localhost [code] wget http://localhost:8000/postorius/api/templates/list/homepage.gruppe.tgcamber… [/code] will return the footer itself - this works fine. Therefore, should i set POSTORIUS_TEMPLATE_BASE_URL to http://localhost:8000? I think, resolving this issue will use the newly configured footer. But I started with the intention to remove alle footers due to the attachement situation described above. Does anybody have an idea how to change the configuration of my list? Are these problems probably related to the import? Currently we are using more then 25 lists with a lot of users. Manually recreating all lists is not possible an could only be a test for a single list. Best regards, chrclaus

"The content of this message was lost."
by skenny＠scss.tcd.ie Sept. 12, 2022

Sept. 12, 2022

I see that this issue has been discussed in a few other postings - it seems to be affecting us here at the moment. We're running Mailman 3.3.5 inside maxking's mailman-core/mailman-web Docker containers (version 0.4.3). This morning I composed a mail message and included two of our mailing lists in the To: field. On the first list I'm a member with address of the form my_addr_1(a)this.com. On the second I'm on it with a different address, my_addr_2(a)that.com. In the case of each list, Mailman held the message for moderation. As administrator, I accepted both. I then got the full message in my inbox at my_addr_1(a)this.com, but in my other inbox at my_addr_2(a)that.com, the body of the message was not present. Instead it read The content of this message was lost. It was probably cross-posted to multiple lists and previously handled on another list. I'm wondering what's the best thing to do here. Should I maybe downgrade to an earlier version of Mailman (i.e. an earlier version of maxking's Docker containers), pending resolution of this issue ...? Thanks for any advice. Stephen PS: The Mailman web interface "System Information" link reports: Mailman Core Version GNU Mailman 3.3.5 (Tom Sawyer) Mailman Core API Version 3.1 Mailman Core Python Version 3.8.10 (default, May 6 2021, 06:30:44) [GCC 9.3.0]

How to set uWSGI buffer size in mailman3 with Dcoker
by bob B Sept. 8, 2022

Sept. 8, 2022

Running into an issue where users are getting a 502 bade gateway and we traced it down to the headers that are getting sent when they request web pages. This looks like our issue ********************* By default, uWSGI allocates a very small buffer (4096 bytes) for the headers of each request. If you start receiving “invalid request block size” in your logs, it could mean you need a bigger buffer. Increase it (up to 65535) with the buffer-size option. ********* So any idea on how to set this in mailman3 running in the maxking docker environment?

mailman3 not working for mailman21 lists
by blup＠fortytwo.ch Sept. 6, 2022

Sept. 6, 2022

I installed mailman3 on a server where mailman21 was installed before. Newly created mailinglists work fine. But if I create mailinglists with a name that was previously used on mailman21 nothing works (same behaviour with and without import of old configs and archives; no logs). I purged all old mailman21 config and data and also old postfix aliases (or at least I do think so). If I send a mail to old list list1(a)a.b and new list list2(a)a.b I get the following logs /var/log/mail.log Aug 21 22:17:40 basilisgg postfix/lmtp[1728]: ED2171120BF: to=<list2(a)c.a.b>, orig_to=<list2(a)a.b>, relay=127.0.0.1[127.0.0.1]:8024, delay=0.31, delays=0.17/0.01/0/0.13, dsn=2.0.0, status=sent (250 Ok) Aug 21 22:17:40 basilisgg postfix/lmtp[1728]: ED2171120BF: to=<list1(a)c.a.b>, orig_to=<list1(a)a.b>, relay=127.0.0.1[127.0.0.1]:8024, delay=0.31, delays=0.17/0.01/0/0.13, dsn=2.0.0, status=sent (250 Ok) /var/log/mailman3/smtp.log ug 21 22:17:40 2022 (934) Available AUTH mechanisms: LOGIN(builtin) PLAIN(builtin) Aug 21 22:17:40 2022 (934) Peer: ('127.0.0.1', 44746) Aug 21 22:17:40 2022 (934) ('127.0.0.1', 44746) handling connection Aug 21 22:17:40 2022 (934) ('127.0.0.1', 44746) Data: b'LHLO c.a.b' Aug 21 22:17:40 2022 (934) ('127.0.0.1', 44746) Data: b'MAIL FROM:<....>' Aug 21 22:17:40 2022 (934) ('127.0.0.1', 44746) sender: ....

FYI: Django security releases issued: 4.0.6 and 3.2.14
by Guillermo Hernandez (Oldno7) Aug. 29, 2022

Aug. 29, 2022

https://www.djangoproject.com/weblog/2022/jul/04/security-releases/ Django security releases issued: 4.0.6 and 3.2.14 Posted by *Mariusz Felisiak* on Julio 4, 2022 In accordance with our security release policy <https://docs.djangoproject.com/en/dev/internals/security/>, the Django team is issuing Django 4.0.6 <https://docs.djangoproject.com/en/dev/releases/4.0.6/> and Django 3.2.14 <https://docs.djangoproject.com/en/dev/releases/3.2.14/>. These release addresses the security issue detailed below. We encourage all users of Django to upgrade as soon as possible. CVE-2022-34265: Potential SQL injection via Trunc(kind) and Extract(lookup_name) arguments Trunc() and Extract() database functions were subject to SQL injection if untrusted data was used as a kind/lookup_name value. Applications that constrain the lookup name and kind choice to a known safe list are unaffected. This security release mitigates the issue, but we have identified improvements to the Database API methods related to date extract and truncate that would be beneficial to add to Django 4.1 before it's final release. This will impact 3rd party database backends using Django 4.1 release candidate 1 or newer, until they are able to update to the API changes. We apologize for the inconvenience. Thanks Takuto Yoshikai (Aeye Security Lab) for the report. This issue has severity "high" according to the Django security policy. -- ___________________________________________ Mailman's content filtering has removed the following MIME parts from this message.

Migrated from MM2 to MM3, all is well except *one* list
by Scott Courtney Aug. 28, 2022

Aug. 28, 2022

Hello, all I have migrated a multi-list server from MM2 to MM3, on Debian 11, and migrated about half a dozen lists with fairly large archives. Absolutely everything has been working for a couple of months, but I am still unable to get one specific list to send mail to its subscribers. Of course, the first place I started was the logs, but that's the problem -- even with logging turned up, it appears to be failing silently as it connects to the MTA. Here's a summary of the environment: OS: Debian Linux 11, 64-bit, on a virtual machine MTA: Exim 4.94.2 List server: Mailman 3.3.3 (installed from Debian repo) Database: MariaDB 10.5.15 All daemons are running on the same host, and communication is either UNIX socket or loopback network interface, for security. Web server: Apache 2.4.53, with proxy to WSGI per the MM3 setup guide Symptom: There are six lists on the server. All six can accept inbound traffic and will post the messages to the (always private, in this environment) archives. The web interface is working perfectly. Five of the lists also can send out messages to subscribers, but the sixth list cannot send traffic to the MTA, or is not attempting to do so. Tests run so far (all resulting in successful posting to archives, but no outbound mail): * Originate mail from inbound SMTP to the list address. * Originate mail from the web UI as a member/moderator. * Originate mail from the web UI as the site admin (also the list owner). * Originate mail from both inbound SMTP and web UI by multiple users. Log data for the inbound traffic (typical test message, some data redacted): 2022-08-27 15:11:57 1oS1Dn-003AWH-Hz <= REDACTED H=REDACTED:25 P=esmtps X=TLS1.3:ECDHE_X25519__RSA_PSS_RSAE_SHA256__AES_128_GCM:128 CV=no K S=2552 DKIM=REDACTED id=REDACTED T="TEST 8.27.001" 2022-08-27 15:11:57 1oS1Dn-003AWH-Hz => MY_LIST(a)lists.MY_DOMAIN R=mailman_main_director T=mailman3_transport H=127.0.0.1 [127.0.0.1] I=[127.0.0.1] C="250 Ok" 2022-08-27 15:11:57 1oS1Dn-003AWH-Hz Completed Log data for MM3 smtp.log (again, partially redacted): Aug 27 15:11:57 2022 (690182) Available AUTH mechanisms: LOGIN(builtin) PLAIN(builtin) Aug 27 15:11:57 2022 (690182) Peer: ('127.0.0.1', 48170) Aug 27 15:11:57 2022 (690182) ('127.0.0.1', 48170) handling connection Aug 27 15:11:57 2022 (690182) ('127.0.0.1', 48170) Data: b'LHLO REDACTED' Aug 27 15:11:57 2022 (690182) ('127.0.0.1', 48170) Data: b'MAIL FROM:<REDACTED>' Aug 27 15:11:57 2022 (690182) ('127.0.0.1', 48170) sender: REDACTED Aug 27 15:11:57 2022 (690182) ('127.0.0.1', 48170) Data: b'RCPT TO:<erevnite(a)lists.4th.com>' Aug 27 15:11:57 2022 (690182) ('127.0.0.1', 48170) recip: MY_LIST(a)lists.MY_DOMAIN Aug 27 15:11:57 2022 (690182) ('127.0.0.1', 48170) Data: b'DATA' Aug 27 15:11:57 2022 (690182) ('127.0.0.1', 48170) Data: b'QUIT' Aug 27 15:11:57 2022 (690182) ('127.0.0.1', 48170) connection lost Aug 27 15:11:57 2022 (690182) Connection lost during _handle_client() Originally I thought the "connection lost" indicated a failure, but that is happening for all the lists, and also on successful traffic. Since it occurs after the QUIT command in the SMTP session, and based on some online searching, my current understanding is that this is harmless and simply indicates the MTA closed the socket after the QUIT.

I know Exim and Mailman are communicating because all the lists use the same SMTP configuration for Exim and Mailman (i.e., the non-working list is not in any way exceptional). I've done a lot of searching online to find a solution, and I did see that a couple of others had asked about this type of problem, but the only one I found that got a response had an issue that didn't apply in my small environment. Absent any other ideas, I'm going to try inserting some trace logging into the Python code, but I can't figure out what's wrong here. I've even gone to the point of looking at the SQL rows to verify this list is exactly parallel to another working list, except its name and integer ID numbers for various unique auto-increment keys. Any suggestions are appreciated. Thanks!

Using REST with CLI using curl .... help needed
by Krešimir Mihalj Aug. 27, 2022

Aug. 27, 2022

Hi ! I need simple add/delete member to list using rest ..... but all documentation is for python and not helpfull for me, .... and I need these in CLI using curl command .... To add member using CLI i tried this command: curl -d "{'list_id' : 'list.domain.com', 'subscriber' : 'user(a)email.com'}" -H 'Content-Type: application/json' --user restadmin:restpass http://localhost:8001/3.0/members and I got this response: Missing parameters: list_id, subscriber What is wrong in above command here ? ..... I need to add user: user(a)email.com to list: list(a)domain.com Also, if someone is willing to give example: delete user: user(a)email.com from list: list(a)domain.com I actually create PHP application .... but CLI example is easy to reproduce in PHP function AddUserToList($user,$lista) { $url = 'http://llocalhost:8001/3.0'; $request_url = $url . '/members'; $data = array("list_id" => $lista,"subscriber" => $user ); $postdata = json_encode($data); $ch = curl_init($request_url); curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); curl_setopt($ch, CURLOPT_USERPWD, "restadmin:restpass"); curl_setopt($ch, CURLOPT_POST, 1); curl_setopt($ch, CURLOPT_POSTFIELDS, $postdata); curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1); curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/json')); $result = curl_exec($ch); curl_close($ch); print_r ($result); } AddUserToList('user(a)email.com','list.domain.com');

DKIM header not added to subscribe/unsubscribe notification email
by Philip Colmer Aug. 24, 2022

Aug. 24, 2022

I have a Mailman 3 server set up with OpenDKIM and Postfix. Each of the lists has been configured so that the DMARC mitigation is "Replace From: with list address" and DMARC Mitigate unconditionally is selected. Everything seems to be working fine *except* when the system sends a notification email to the list owners of someone subscribing or unsubscribing. *Those* emails do not have the DKIM header added and are getting trapped by anti-spam systems as a result. Any suggestions as to why this might be, please? I cannot see anything in the configuration for OpenDKIM or Postfix that might allow just those messages to go out unsigned. In case it is relevant/important, this system is running: mailman 3.3.5 mailman-hyperkitty 1.2.0 mailman-web 0.0.5 mailmanclient 3.3.3 Thank you. Regards Philip

MM3 not starting
by max.diener＠hpi.de Aug. 22, 2022

Aug. 22, 2022

Hi, i am trying to install MM3 and had a few issues with it. First i was trying the Mailman3-full package for Debian which didnt work good for me. There was missing paths and files, after some research i found out it may not be well maintained right now. I was working to fix the issue i come up with but had no luck with it. After that i was trying this Howto: https://wiki.list.org/DOC/Howto_Install_Mailman3_On_Debian10 the Installation worked in some aspect. i had a running mailman3 service but the webinterfaces was not working. After some searching i found a issue that was stating that the current release had a bug in it wich made it not working. For instance was the config file different for "systemctl start mailman3" then when i was checking it "mailman info" and some paths was not like in the instructions again, this time i added the folders and put the files needed for it in to it but could not make it work. i kept digging and find out for prod it is best practice to install in a virtual environment so i waited for the bug to fix and took this Installation Instructions: https://docs.list.org/en/latest/install/virtualenv.html#virtualenv-install i was a little bit confused that there seems to be two spots from the official site where you can find Installation Instructions: https://wiki.list.org/DOC/ and https://docs.list.org/ since the last one made it seem like it was newer i choose the venv installation instructions. From the install instructions at https://docs.list.org/en/latest/install/virtualenv.html#virtualenv-install i was seeing that there is also some folders not showing up like mentioned in the howto: /op/mailman/mm was not there. In the part where you configure mailman core it says you need to add the /etc/mailman/mailman.cfg file it shows that the path is used for the hyperkitty config as well as it is the path vor the "var_dir: /opt/mailman/mm/var". i added the paths and at the point in the install instructions here https://docs.list.org/en/latest/install/virtualenv.html#starting-mailman-au… i checked if i can start mailman3 now but still fail to do so. when i check "journalctl -xe" i find the following information but cant get more information on how to fix it in the net with it: Aug 22 09:54:05

Gunicorn problem?

Cannot connect to SMTP server
by mkummini＠cmi.ac.in Aug. 14, 2022

Aug. 14, 2022

Hello. I am setting up a new mailman3 server (debian 11). `mailman3-full` is installed on the same server as postfix (our MTA). There is just one test mailing list now. When I send a message to it (I am a subscriber), mailman3 accepts the message through LMTP. Both the postfix log and mailman.log confirm this. Postfix log: Aug 14 03:21:25 mail postfix/lmtp[4097036]: 44E49272437D: to=<testlist(a)cmi.ac.in>, relay=127.0.0.1[127.0.0.1]:8024, delay=0.15, delays=0.02/0.03/0.01/0.09, dsn=2.0.0, status=sent (250 Ok) mailman.log: Aug 14 03:21:26 2022 (4096856) ACCEPT: <Yvgc3WsoFlpZbypw(a)cmi.ac.in> (The digest.mmdf file shows the test message I sent. Hence mailman3 has received the message from postfix.) However, after this, the postfix log does not show any attempt by mailman3 to send the message to the list members. The following runners have started (after the most recent mailman3 restart) Aug 14 03:19:53 2022 (4096853) archive runner started. Aug 14 03:19:53 2022 (4096863) retry runner started.

RE in Ban List
by Peter Chubb Aug. 12, 2022

Aug. 12, 2022

Hi I tried to add the regular expression sales@.* to the ban list for one of my lists and got: An error occurred: Invalid Parameter "email": Expected a valid email address or regular expression, got sales@.*. Now, 'sales@.*' _is_ a valid regular expression --- so why did it fail? (I wanted to ban that set of addresses, because we get an awful lot of chinese spam from sales@some-company-name where the company name is variable) Peter C

MM3 not processing some mails from specific user
by Stefan Bauer Aug. 12, 2022

Aug. 12, 2022

Hi, we are running MM3¹ and from time to time, a mail to a mailing list is not processed by MM. MM sees the mail but still does nothing with it. If another user is sending _same_ mail, it is processed. Any idea what that could be? Here are some logs: Apr 27 13:02:13 2022 (1919) ('127.0.0.1', 44800) handling connection Apr 27 13:02:13 2022 (1919) ('127.0.0.1', 44800) Data: b'LHLO mal01.mydomain.tld' Apr 27 13:02:13 2022 (1919) ('127.0.0.1', 44800) Data: b'MAIL FROM:<john.doe(a)mydomain.tld>' Apr 27 13:02:13 2022 (1919) ('127.0.0.1', 44800) sender: john.doe(a)mydomain.tld Apr 27 13:02:13 2022 (1919) ('127.0.0.1', 44800) Data: b'RCPT TO:<ssa(a)mydomain.tld>' Apr 27 13:02:13 2022 (1919) ('127.0.0.1', 44800) recip: ssa(a)mydomain.tld Apr 27 13:02:13 2022 (1919) ('127.0.0.1', 44800) Data: b'DATA' Apr 27 13:02:13 2022 (1919) ('127.0.0.1', 44800) Data: b'QUIT' Apr 27 13:02:13 2022 (1919) ('127.0.0.1', 44800) connection lost Here is a snipped from same user, but different mail that is also not processed by MM: Subject: =?iso-8859-1?Q?Kleine_=C4nderung?= From: john.doe(a)mydomain.tld To: =?us-ascii?Q?ssa=40mydomain=2Etld?= <ssa(a)mydomain.tld> Date: Wed, 10 Aug 2022 12:33:36 +0000 Mime-Version: 1.0 Content-Type: multipart/alternative; boundary="=_m+9Z-w1zPVUy50id4xiOsxEs50Bl3xTDSq7AWqqonRf21H5c" Thread-Index: AdistWce8WLKbSqIReeBnR+y5yR5Mw== Message-Id: <kcEE.3C4Toxi/SomLpNH7qUNdhg.gBB2y7Ws2AE(a)mx1.mydomain.tld> This is a multi-part message in MIME format.

Mailman recovery test did not go as planned
by bob B Aug. 9, 2022

Aug. 9, 2022

I have a test Mailman 3 environment. We are using docker, and we are running the database outside of docker in mysql. I need to perform a DR recovery test. I shut down Mailman in docker (mailman-core & mailman-web, the only docker images I have running for Mailman). While Mailman was stopped, I had our database team take a backup dump of the database. I then restarted Mailman in docker. I threw some more messages at a test list. I validated that the new messages were delivered, and showed up in the archive. I shut down Mailman again. I had the database team restore the Mailman database from the backup. I started Mailman I logged into Mailman I was expecting to see the messages in the archive prior to the backup and all the messages after the backup would be gone. When went into the list archive, I get a spinning icon and no messages showed up. I quit, restarted my browser, and logged in again, and the same thing. I then sent a test message to the list and the message was delivered to the list. Then when I went to check the archive, the spinning icon was gone and that test message was there along with all the messages before the backup was taken. Is this normal? After a restore did the new message cause a refresh of archived messages etc? Is there a way to do this without sending a message to a list after a restoration of the database? Are there better steps I should take when restoring the database? Thanks

Detectors and Bounces
by summersan＠nclack.k12.or.us Aug. 5, 2022

Aug. 5, 2022

Hello All, I've recently upgraded a Mailman 3 server from Debian 10.12 to Debian 11.4 [1]. In that process, I've also upgraded Mailman 3 from version 3.3.4 to version 3.3.5. I think the following guide was originally used when setting up Mailman 3 on the present server: https://wiki.list.org/DOC/Howto_Install_Mailman3_On_Debian10 . After that upgrade process, I've noticed that at least one `mailman` process and one `postgres` process were at something like 40 %CPU or higher for extended periods of time (seen using `top` command). Upon further inspection, and through some research online, it seemed like the issue might have to do with bounces (maybe not processing or something) [2][3][4][5][6][7][8]. In my logcheck logs, I was seeing this message multiple times a second: `Running detector: <class 'flufl.bounce._detectors.dsn.DSN'>` I ended up trying to clear out the `/opt/mailman/mm/var/queue/bounces` and `/opt/mailman/mm/var/locks` directories to see if that would help. There seemed to be some sort of positive change, because the log message "spamming" seemed to decrease. The high %CPU for the `mailman` and `postgres` processes in question also seemed to go down over time. But the related `mailman` process would still run at a high %CPU from time to time. I tried checking the `mailman` process using `strace` at some point, but I didn't see an easily evident cause for what was going on—from what I remember, there was something about a "POLLIN" or something that kept looping. When I go to check the same `mailman` process with `strace` today, I just see occasional messages like this: `select(0, NULL, NULL, NULL, {tv_sec=45, tv_usec=43171}) = 0 (Timeout)` My Questions: Is it normal to see large amounts of `Running detector: <class 'flufl.bounce._detectors.dsn.DSN'>` lines in logs? Should there normally be other detectors listed in the logs beyond the `DSN` one? If so, is there a setting I can change somewhere to make this happen? For reference, I can only find one other logcheck log that shows a `Running detector: <class 'flufl.bounce._detectors.dsn.DSN'>` line from before the recent Mailman 3 upgrade. In that past logcheck log, there are other detectors listed as well, which makes me wonder if something is still stuck with the new Mailman 3 install (or if maybe something needs to be changed in a setting file somewhere): Here is an example of previous log lines: Running detector: <class 'flufl.bounce._detectors.sina.Sina'> Running detector: <class 'flufl.bounce._detectors.llnl.LLNL'> Running detector: <class 'flufl.bounce._detectors.exim.Exim'> Running detector: <class 'flufl.bounce._detectors.qmail.Qmail'> Running detector: <class 'flufl.bounce._detectors.exchange.Exchange'> Running detector: <class 'flufl.bounce._detectors.netscape.Netscape'> Running detector: <class 'flufl.bounce._detectors.dsn.DSN'> Running detector: <class 'flufl.bounce._detectors.caiwireless.Caiwireless'> Running detector: <class 'flufl.bounce._detectors.aol.AOL'> Running detector: <class 'flufl.bounce._detectors.yale.Yale'> Running detector: <class 'flufl.bounce._detectors.smtp32.SMTP32'> Running detector: <class 'flufl.bounce._detectors.groupwise.GroupWise'> Running detector: <class 'flufl.bounce._detectors.simplewarning.SimpleWarning'> Running detector: <class 'flufl.bounce._detectors.microsoft.Microsoft'> Running detector: <class 'flufl.bounce._detectors.postfix.Postfix'> Running detector: <class 'flufl.bounce._detectors.simplematch.SimpleMatch'> Running detector: <class 'flufl.bounce._detectors.yahoo.Yahoo'> Thank you for your time, Andy ----- Web References: [1] https://www.debian.org/News/2022/2022032602 [2] https://mail.python.org/archives/list/mailman-developers@python.org/thread/… [3] https://phabricator.wikimedia.org/T282348 [4] https://mail.python.org/archives/list/mailman-users@python.org/thread/MISUM… [5] https://lists.mailman3.org/archives/list/mailman-users@mailman3.org/thread/… [6] https://lists.mailman3.org/archives/list/mailman-users@mailman3.org/message… [7] https://lists.mailman3.org/archives/list/mailman-users@mailman3.org/thread/… [8] https://lists.mailman3.org/archives/list/mailman-users@mailman3.org/thread/…

Rpsamd greylist configuration for Mailman3

Hello, I'm in the process of configuring Rspamd with the Mailman3 server. If Rspamd flags a message under 'greylist' and accepts it after the temporary rejection, is there any way mailman can move that message to the moderator's queue? if it is possible, can someone send me the instructions, please? Kind regards, Prasanth Nair

Mailman 3 questions (purge archives, list metrics, and auto discard held messages)
by bob B Aug. 2, 2022

Aug. 2, 2022

Some quick mailman3 questions --Just wanted to check that there is still no way for mailman3 to automatically purge archived emails after a set amount of time? it looks like you have to export the database, purge the messages, then re-import, is this still the only/best way to purge old archived messages? --I noticed on the list info page you have metrics, which is straightforward except for "volume" My volume number is not increasing? What is that counting exactly? --Is there any way to auto discard held messages after x amount of time? I assume not but had a user ask if that was an option. Thanks for the assistance in advance.

A customer we support wants to migrate a substantial Mailman 2 installation to Mailman 3. We have a team that can handle much, even perhaps most of this, but it’s an important project and we’d prefer to have a deep expert on the team for help/advice and the heavy lifting. Can anyone here recommend and engineer, perhaps even you, who could get involved with us commercially to help make a Mailman 2 to 3 migration successful? Thank you all, and I hope I’ve not violated any list guidelines by asking… You can contact me off-list if you prefer - I’m quite easy to find… Best regards to all, Mark Mark Taylor, Chief Executive Officer SiriUS: Infrastructure for Entrepreneurs® https://www.siriusopensource.com t: +001 509 254 5005

Programmatic Creation of Users
by jciesla＠techsupportme.com July 30, 2022

July 30, 2022

I am returning to Mailman after being away for a LONG time and I need to create 40 lists with ~350 subscribers spread across those lists. After a lot of testing I am now able to create users from the Core Shell and set (most of) the necessary values. Having jumped that hurdle I have hit a roadblock and I am hoping that the list can provide some insight and/or solutions. After a lot of research I now understand that what I am doing in the Core Shell is creating a User entity which has one or more email addresses as well as one or more roles and preferences that exist at the global level. This user entity can Subscribe to zero or more lists. If I am incorrect in the summation please let me know! Assuming that the previous information is correct that brings us to my current dilemma. Specifically, the User entity can Subscribe and interact with lists using the email commands, but they can't Login using the Postorius web interface. If I understand correctly the reason that they can't login is that the underlying Django system does not recognize their account because the account that was created in Core isn't accessible by Django. Instead the user needs to create a Django-specific account at which point the information from Core becomes available in the user's web UI. If that is in fact accurate then I want to take the next logical leap: is it possible to programmatically create an account in Django that is tied to the account that was created in Core? Any information is greatly appreciated! -John

Shorted Subjects in Mailman
by Stephan Krinetzki July 27, 2022

July 27, 2022

Hello all, We have been experiencing the following problem lately: When a user sends a mail with an unusually long subject to a mailing list, this subject is shortened. Here are the two examples: Original subject: "[SAV-LINUX] Notice from Sophos Anti-Virus on lx1bcms-storage.physik.rwth-aachen.de" (82 characters long) Subject in Mailman: "[edv-support][SAV-LINUX] Notice from Sophos Anti-Virus on" (57 characters long) Is there a rule that Mailman truncates the subject or why does this happen? Is there any way to work around this? In the Mailman Topic Header, however, the full subject is always readable. Translated with www.DeepL.com/Translator (free version)

One example from today was logged as follows: [pid: 2287|app: 0|req: 116007/153551] xxx.xx.xx.xx () {72 vars in 1992 bytes} [Thu Jun 30 11:26:16 2022] POST /archives/list/listname(a)domainname.org/message/46WUOPZITVMKJN4TXR6CP3WMFUEAVJKD/reply => generated 3213 bytes in 70 msecs (HTTP/1.1 200) 6 headers in 188 bytes (3 switches on core 0) A couple of basic questions: 1) when a users replies in this manner, does their response go to the list or to the subscriber to whom they are replying? 2) what log files could I check to see what — if anything — happens to these emails? 3) Are there any settings that need to be set to make this work? Thanks much. Any help will be appreciated. Jeff

I'm trying to move my mailman3 web interface from example.com/mailman3 to just lists.example.com like this site. I am not having luck with the apache configuration. I've tried below but I just get a 403: <VirtualHost *:80> ServerAdmin admin(a)example.com ServerName lists.example.com ServerAlias www.lists.example.com <Directory "/var/lib/mailman3/web/static"> Require all granted </Directory> <IfModule mod_proxy_uwsgi.c> ProxyPass /favicon.ico ! ProxyPass /static ! ProxyPass / unix:/run/mailman3-web/uwsgi.sock|uwsgi://localhost </IfModule> </VirtualHost> Alias /favicon.ico /var/lib/mailman3/web/static/postorius/img/favicon.ico Alias /static /var/lib/mailman3/web/static

Hi, Currently, I use a nginx configuration for mailman. It's work perfectly. I tried to do the same with Apache, but the statics files are not delivered (404). Basically, it's the same configuration: /server { listen 80; server_name mailing.ddd.fr; access_log /var/log/nginx/mailing.access.log; error_log /var/log/nginx/mailing.error.log; location /static/ { alias /opt/mailman/static/; expires 30d; } proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; location / { proxy_pass http://localhost:8000; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; } } <VirtualHost *:80> ServerName mailing.ddd.fr ErrorLog ${APACHE_LOG_DIR}/mailing.error.log CustomLog ${APACHE_LOG_DIR}/mailing.access.log combined <Location /static/> Alias "/opt/mailman/static/" </Location> <Location /> ProxyPass http://localhost:8000/ ProxyPassReverse http://localhost:8000/ ProxyPreserveHost On </Location> </VirtualHost>/ I missed something ? Thanks.

List and Domain listing slow
by Patrik Peng July 25, 2022

July 25, 2022

Hi there Recently we migrated 4000+ lists from Mailman 2 to 3 and noticed a drastic slowdown of response time (30+ secs) when listing lists or domains while logged in as any user. Affected are the following paths: * https://mm3.com/mailman3/lists/ * https://mm3.com/mailman3/domains/ When visiting one of the affected pages, a lot of API requests are visible in `mailman.log`: [25/Jul/2022:11:02:02 +0200] "GET /3.1/domains/domain1.com HTTP/1.1" 200 202 "-" "GNU Mailman REST client v3.3.3" [25/Jul/2022:11:02:02 +0200] "GET /3.1/domains/domain2.com HTTP/1.1" 200 188 "-" "GNU Mailman REST client v3.3.3" [25/Jul/2022:11:02:02 +0200] "GET /3.1/domains/domain3.com HTTP/1.1" 200 200 "-" "GNU Mailman REST client v3.3.3" [25/Jul/2022:11:02:02 +0200] "GET /3.1/domains/domain4.com HTTP/1.1" 200 218 "-" "GNU Mailman REST client v3.3.3" I'm suspecting an n+1 issue where a request is made for every list entry and even if the API response times are quick (15-20ms), this time accumulates.
