What is the difference between Mime Digest and Summary Digest in Mailman 3.2.0?
by Henrik Rasmussen Dec. 5, 2018

Dec. 5, 2018

Having tried both Outlook and Gmail, there doesn't seem to be any visible difference between Mime Digest and Summary Digest. Of cause Gmail shows both index and all posts inline while Outlook shows both index and all posts as attachments, but overall the two digest types doesn't seem different from each other. Is that corrent or did I miss something? /Henrik Rasmussen

Mysql issue in django migrations
by Peter Sørensen Dec. 5, 2018

Dec. 5, 2018

Hi, I have seen others having below problem: File "/usr/local/lib/python3.6/dist-packages/django/db/migrations/recorder.py", line 57, in ensure_schema raise MigrationSchemaMissing("Unable to create the django_migrations table (%s)" % exc) django.db.migrations.exceptions.MigrationSchemaMissing: Unable to create the django_migrations table ((1064, "You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '(6) NOT NULL)' at line 1")) But haven’t been able to find a proper solution. It’s not a syntax problem. Can anyone help ? Best regards Peter Sørensen/University of Southern Denmark

HyperKitty/Mailman3 issues
by Florian Schulze Dec. 4, 2018

Dec. 4, 2018

Hi! I tried setting up Scheduled Tasks as described in <http://docs.mailman3.org/en/latest/config-web.html#scheduled-tasks-required> but the "runjobs" command can't be found. I see the hyperkitty and mailman commands when using "help". The "qcluster" service is working. Using Django 2.1.1 and HyperKitty 1.2.1. Maybe related to that, I have two issues with archives. 1. Changing the archiving setting in the Web-UI to something else than public seems to have no effect. The already archived messages are still accessible in public. 2. Related to 1., how can I remove a list archive without affecting other lists? Regards, Florian Schulze

Dear list, I'd like to change the sending address of a mailinglist, but when I try to set it via mmclient with ./manage.py mmclient lists=client.lists l=lists[listnumber] l.settings['posting_address']='new name' I get `ValueError: value is read-only`. Is it possible to change this value, or should I use another setting for this objective? Best regards, Johannes Winter

Setup Mailman3 on shared webhost
by Keyra Nov. 8, 2018

Nov. 8, 2018

Iam trying to setup mailman3 on a shared webhost (with ssh access). I could use pip3.6 install mailman --user and also mailman info But when I try to start mailman using mailman start I will first get the error message TypeError: expected str, bytes or os.PathLike object, not NoneType and when I try it a second (and third etc.) time, it throws Starting Mailman's master runner /usr/bin/python3.6: can't open file '/usr/bin/master': [Errno 2] No such file or directory I didn't get any error messages during installation, so I guess whatever mailman is looking for in /user/bin/master is available in my /home/user/ folder, but I have no idea where and how to tell mailman to look there. For more infos, this is the output of `mailman info` GNU Mailman 3.2.0 (La Villa Strangiato) Python 3.6.5 (default, Apr 10 2018, 17:08:37) [GCC 4.8.5 20150623 (Red Hat 4.8.5-16)] config file: /var/www/virtual/user/html/var/etc/mailman.cfg db url: sqlite:////var/www/virtual/user/html/var/data/mailman.db devmode: DISABLED REST root url: http://localhost:8001/3.1/ REST credentials: restadmin:XXXX

Mailman 3 on RHEL 7 help
by A Almeda Nov. 3, 2018

Nov. 3, 2018

Hi. I am trying to install mailman 3 on RHEL7. Docker install is not a possibility. I am trying to install it using a bundler by following https://media.readthedocs.org/pdf/mailman-bundler/stable/mailman-bundler.pdf, but after logging in as mailman, I can't do virtualenv venv. It works if I login as root, but still fails during buildout. In short, I need help. Has anyone of you guys installed mailman 3 on RHEL 7 or CEntOS 7? If so would you share me detailed instructions? Thank you in advance.

Hi, I am running a static website with jekyll and I want to integrate a form that executes a subription rest api call to mailman. From my first investigation this seems to be a bad idea from a security perspective (rest api needs managaer access). Is there a secure way to do this? Any other ideas? Regards Hagen

autoresponse not sent
by shadiakiki1986＠gmail.com Oct. 22, 2018

Oct. 22, 2018

Hello. Newbie to mailman here. I tried out mailman3 today. My setup is - mailman3 suite using the docker-compose file from asynchronous.io - exim4 on the local machine and configuring it as smarthost using mailgun smtp server The emails to the mailing list are received by the subscribers, but the autoresponse is not being received by the sender (who is not from the subscribers list). I'm not sure if the problem is from mailman-core, settings from mailman-web, or from exim. The setting for autoresponse to posters is set to yes, with some text to be sent in the autoresponse message. The autoresponse grace period is set to "0d60.0s" (I was unable to set to "0" or "negative" due to error saying something like "could not update parameter") The "Acknowledge posts" in the "global mailman settings" is set to "yes". The "Acknowledge posts" in the list-based preferences is also "yes". Here are the exim logs after I send the email from the non-subscriber to the mailing list ``` 2018-10-19 15:13:32 1gDWSy-0004n7-VR DKIM: d=gmail.com s=20161025 c=relaxed/relaxed a=rsa-sha256 b=2048 [verification succeeded] 2018-10-19 15:13:32 1gDWSy-0004n7-VR <= shadiakiki1986(a)gmail.com H=mail-vk1-f171.google.com [209.85.221.171] P=esmtp K S=2416 id=CACk+RNtq_hu+M_ufoCJQFCtOWOD_DX0omdVJbKfva0w=n4Qhuw(a)mail.gmail.com 2018-10-19 15:13:33 1gDWSy-0004n7-VR => quotations(a)mailman3.akikieng.com R=mailman3_router T=mailman3_transport H=172.19.199.2 [172.19.199.2] C="250 Ok" 2018-10-19 15:13:33 1gDWSy-0004n7-VR Completed 2018-10-19 15:13:35 1gDWT1-0004nC-1I DKIM: d=gmail.com s=20161025 c=relaxed/relaxed a=rsa-sha256 b=2048 [verification failed - signature did not verify (headers probably modified in transit)] 2018-10-19 15:13:35 1gDWT1-0004nC-1I <= quotations-bounces(a)mailman3.akikieng.com H=ip-172-19-199-2.us-west-2.compute.internal [172.19.199.2] P=esmtp S=3847 id=CACk+RNtq_hu+M_ufoCJQFCtOWOD_DX0omdVJbKfva0w=n4Qhuw(a)mail.gmail.com 2018-10-19 15:13:35 1gDWT1-0004nC-1I => shadi(a)akikieng.com R=smarthost T=remote_smtp_smarthost H=smtp.mailgun.org [35.161.201.187] X=TLS1.2:ECDHE_RSA_AES_256_GCM_SHA384:256 CV=yes DN="C=US,ST=California,L=San Francisco,O=MAILGUN TECHNOLOGIES\, INC,OU=MAILGUN TECHNOLOGIES\, INC,CN=*.mailgun.org" A=plain C="250 Great success" 2018-10-19 15:13:35 1gDWT1-0004nC-1I Completed ``` 1. Is the signature verification failure due to mailman-core trying to send the autoresponse outgoing message?

MM3 vs. Sympa
by Tom Browder Oct. 21, 2018

Oct. 21, 2018

I still haven’t gotten around to getting a new MM3 service up and running, and now I’m looking at Sympa. I’ve seen a few comparisons of the two systems on the net, but the ones I’ve seen are for announcement lists only. I did see one university that did a study of list managers to replace Listproc and chose Sympa. I must admit my short-lived MM2 experience (used for my social sites for my high school and college classmates) seven years ago wasn’t the best was for two reasons: (1) no duplication of list names even for different domains and (2) it’s written in Python (instead of Perl). But, thanks to much help from Mark, I did get it runnng. I think it would be running today but it failed after about a year when Gmail (whose sntp server I was using) stopped allowing that, and I just didn’t know enough to get around the situation and had too much else to do. I waited expectantly for MM3 to come out and was ready to try again, but the separation of a formerly-integrated system into several systems was a bit daunting. Now I’m considering using Sympa: it’s coded in Perl, it’s monolithic, and it can support identical list names for different domains, so I am leaning in that direction. Before I go, I would appreciate anyone giving me a good reason to stay with MM (besides excellent support and a welcoming community—one which is a member of an unfortunately small group of such communities). Thanks so much. Best regards, -Tom

Difficulties setting up MM3 with Postfix MTA in Docker Environment: Invalid EHLO domain name & Authentification as lists.local
by Niklas Frühauf Oct. 21, 2018

Oct. 21, 2018

Hi everyone, I managed to setup mailman using the maxking/mailman-* docker containers, connected to a postfix/dovecot mailserver and a mysql database. The mail domain is @mail.local, mailman is reachable at lists.local. I can see the mailman UI fine, its connection to the database is working as well, the only things that’s not working is the initial login: When I try to login with the correct credentials of the superuser I added, I get An error occurred while processing your request. To me it seems like mailman is trying to authenticate as “lists.local” or “mail.local” or “localhost” to postfix (which of course isn’t working), then issues a EHLO/HELO to postfix which is not a FQDN. So I guess the latter issue could be resolved by providing a FQDN by mailman. These are the logfiles from the period: mail | Oct 21 11:15:07 mail postfix/postscreen[1862]: CONNECT from [172.18.18.8]:49288 to [172.18.18.254]:25 ldap_1 | 5bcc5fc1 conn=1000 fd=12 ACCEPT from IP=172.18.19.8:49252 (IP=0.0.0.0:389) ldap_1 | 5bcc5fc1 conn=1000 op=0 BIND dn="cn=admin,dc=..." method=128 ldap_1 | 5bcc5fc1 conn=1000 op=0 BIND dn="cn=admin,dc=..." mech=SIMPLE ssf=0 ldap_1 | 5bcc5fc1 conn=1000 op=0 RESULT tag=97 err=0 text= ldap_1 | 5bcc5fc1 conn=1000 op=1 SRCH base="ou=users,dc=..." scope=2 deref=0 filter="(mail=lists.local)" ldap_1 | 5bcc5fc1 conn=1000 op=1 SRCH attr=mail ldap_1 | 5bcc5fc1 conn=1000 op=1 SEARCH RESULT tag=101 err=0 nentries=0 text= ldap_1 | 5bcc5fc1 conn=1000 op=2 SRCH base="ou=users,dc=..." scope=2 deref=0 filter="(?mailGroupMember=lists.local)" ldap_1 | 5bcc5fc1 conn=1000 op=2 SRCH attr=mail ldap_1 | 5bcc5fc1 conn=1000 op=2 SEARCH RESULT tag=101 err=0 nentries=0 text= ldap_1 | 5bcc5fc1 conn=1000 op=3 SRCH base="ou=users,dc=..." scope=2 deref=0 filter="(|(mail=*@lists.local)(mailalias=*@lists.local))" ldap_1 | 5bcc5fc1 conn=1000 op=3 SRCH attr=mail ldap_1 | 5bcc5fc1 <= mdb_substring_candidates: (mail) not indexed ldap_1 | 5bcc5fc1 <= mdb_substring_candidates: (mailalias) not indexed ldap_1 | 5bcc5fc1 conn=1000 op=3 SEARCH RESULT tag=101 err=0 nentries=0 text= ldap_1 | 5bcc5fc1 conn=1000 op=4 SRCH base="ou=users,dc=..." scope=2 deref=0 filter="(mail=mail.local)" ldap_1 | 5bcc5fc1 conn=1000 op=4 SRCH attr=mail ldap_1 | 5bcc5fc1 conn=1000 op=4 SEARCH RESULT tag=101 err=0 nentries=0 text= ldap_1 | 5bcc5fc1 conn=1000 op=5 SRCH base="ou=users,dc=..." scope=2 deref=0 filter="(?mailGroupMember=mail.local)" ldap_1 | 5bcc5fc1 conn=1000 op=5 SRCH attr=mail ldap_1 | 5bcc5fc1 conn=1000 op=5 SEARCH RESULT tag=101 err=0 nentries=0 text= ldap_1 | 5bcc5fc1 conn=1000 op=6 SRCH base="ou=users,dc=..." scope=2 deref=0 filter="(|(mail=*@mail.local)(mailalias=*@mail.local))" ldap_1 | 5bcc5fc1 conn=1000 op=6 SRCH attr=mail ldap_1 | 5bcc5fc1 <= mdb_substring_candidates: (mail) not indexed ldap_1 | 5bcc5fc1 <= mdb_substring_candidates: (mailalias) not indexed ldap_1 | 5bcc5fc1 conn=1000 op=6 SEARCH RESULT tag=101 err=0 nentries=0 text= ldap_1 | 5bcc5fc1 conn=1000 op=7 SRCH base="ou=users,dc=..." scope=2 deref=0 filter="(mail=lists.local)" ldap_1 | 5bcc5fc1 conn=1000 op=7 SRCH attr=mail ldap_1 | 5bcc5fc1 conn=1000 op=7 SEARCH RESULT tag=101 err=0 nentries=0 text= ldap_1 | 5bcc5fc1 conn=1000 op=8 SRCH base="ou=users,dc=..." scope=2 deref=0 filter="(?mailGroupMember=lists.local)" ldap_1 | 5bcc5fc1 conn=1000 op=8 SRCH attr=mail ldap_1 | 5bcc5fc1 conn=1000 op=8 SEARCH RESULT tag=101 err=0 nentries=0 text= ldap_1 | 5bcc5fc1 conn=1000 op=9 SRCH base="ou=users,dc=..." scope=2 deref=0 filter="(|(mail=*@lists.local)(mailalias=*@lists.local))" ldap_1 | 5bcc5fc1 conn=1000 op=9 SRCH attr=mail ldap_1 | 5bcc5fc1 <= mdb_substring_candidates: (mail) not indexed ldap_1 | 5bcc5fc1 <= mdb_substring_candidates: (mailalias) not indexed ldap_1 | 5bcc5fc1 conn=1000 op=9 SEARCH RESULT tag=101 err=0 nentries=0 text= mail | Oct 21 11:15:13 mail postfix/postscreen[1862]: PASS OLD [172.18.18.8]:49288 mail | Oct 21 11:15:13 mail postfix/smtpd[1873]: connect from srv-docker_mailman-web_1.srv-docker_frontend[172.18.18.8] mail | Oct 21 11:15:17 mail postfix/postscreen[1862]: warning: dnsblog reply timeout 10s for list.dnswl.org mail | Oct 21 11:15:27 mail postfix/dnsblog[1866]: warning: dnsblog_query: lookup error for DNS query 8.18.18.172.list.dnswl.org: Host or domain name not found.

dkim failing
by Abhijith PA Oct. 16, 2018

Oct. 16, 2018

Hello. I am seeing dkim fail in mail that people send to lists /dkim=fail reason="signature verification failed"/ but it is not happening when the list solely sending mail to subscribers (like digest, or subscribe/unsubscribe messages etc). I recently added a new domain to the mailman3. After this I started noticing this issue. Any help ?

Change digest frequency and default threshold
by Henrik Rasmussen Oct. 12, 2018

Oct. 12, 2018

When creating a new list in Mailman 3, the Digest Size Threshold is set to 30KB, which is not much in my opnion. 1) How do I set another default for Digest Size Threshold for new lists. 2) How do I change the default for existing lists When Digest Size Threshold is not reached, mails seems to be sent according to digest_volume_frequency': which is set to 'monthly'. The web interface doesn't seem to have a setting for this. How do I change this setting, both on a single list and the default for new lists? Henrik Rasmussen

Can't remove footer(s)
by Henrik Rasmussen Oct. 11, 2018

Oct. 11, 2018

I have a problem removing the footer(s) from a list imported from MM2.1. I have been testing by entering my message in Hyperkitty (the list forum). I an aware about the double footer issue[1], and I am aware that footers are cached, but I have removed the footer files according to [2], run Mailman shell according to [3], restarted the Mailman (Mailman core, Mailan web, Postgres database and postfix). Did I miss something in order to remove the footers?

Proper permissions for mailman installation under home directory, with layout: local
by Eric Abrahamsen Oct. 3, 2018

Oct. 3, 2018

I recently upgraded my server from Ubuntu 16.04 to 18.04, and have hit some snags in the process. I've had my mailman3 installation under my home directory, running as my own user, without too many problems. var_dir was set to something in my home directory. Recently, while tracking down some weird behavior, I realized that with this sort of setup I'm supposed to use "layout: local", and that previously I'd had a sort of weird half-way installation where some things were kept in my /home/<me>/sites/mailman directory, and other bits (pids and whatnot) were scattered around the filesystem. Now that I'm using "layout: local", mailman really is trying to keep everything under that main directory, and now everything's breaking. The hyperkitty search indexer is saying it has no permissions to write into that directory, postfix won't deliver mail, saying the mailbox is unavailable, and in the web UI postorius shows no configured list domains (though hyperkitty still displays the archives correctly). So obviously I've got quite a big problem with permissions, but I don't know how to resolve it. My webserver is nginx, running as www-data. I'm starting mailman in a systemd script, with User and Group set to my user -- though maybe that should be set to root? I guess postfix runs as root, I'm not sure, but obviously it's not able to read the files in var/data/*, which appear all correct to me. What's the recommended solution here? I'd still like to keep this whole directory under my home directory, if possible... Thanks, Eric

Hyperkitty splitting threads?
by Marvin Gülker Sept. 30, 2018

Sept. 30, 2018

Hi, I'm experiencing a problem with regard to how Hyperkitty decides how to group messages into a thread. It appearently randomly splits a thread and creates a new one from the replies, even though the replies have the proper In-Reply-To: header set. As of now, the front page for our mailing list[1] illustrates the issue nicely: the "TSC Boost Build Issues" topic has been split over three threads for no appearent reason, and the "Providing an APT repository" one in two. Sometimes replies are collected into the proper thread, though (see the latter thread). Exact links follow as the front page can change later on: * The "Boost Build Issues" topic (these should all be in one thread page): * https://lists.secretchronicles.org/hyperkitty/list/tsc-devel@lists.secretch… * https://lists.secretchronicles.org/hyperkitty/list/tsc-devel@lists.secretch… * https://lists.secretchronicles.org/hyperkitty/list/tsc-devel@lists.secretch… * The "APT repository" topic (these should all be in one thread page as well): * https://lists.secretchronicles.org/hyperkitty/list/tsc-devel@lists.secretch… * https://lists.secretchronicles.org/hyperkitty/list/tsc-devel@lists.secretch… This is Mailman 3.2.0 with Hyperkitty 1.2.0. We will shortly upgrade Hyperkitty to the current version, but since I didn't find something related in the release notes for newer versions, I thought I'd ask here if the problem is known. Also, is there a way to rebuild the thread structure so that the existing errorneous splits can be corrected?

Docker-mailman: Performance issue
by Henrik Rasmussen Sept. 28, 2018

Sept. 28, 2018

I am using Docker-mailman (currently Mailman version 3.2.0a1). I have a list with 38513 subscribers and when I operate on a very large number of them (for example click Unsubscribe all), the web interface times out. The same happens if I use the REST API, one member at the time, but run from a python script i've made). The Docker containers for both Mailman core (mostly) and mailman web (sometimes) are using 100% CPU (quart of the server's amount of CPUs). By doubleing the CPU shares that the two docker containers can use (using RHEL Cockpit) from 1024 to 2048 for each, Mailman-core had a max usage of 190% and Mailman-web about 101%. Still, mass unsubscribing the members by clicking Unsubscribe all made theinterface time out. Using the REST API succeeded unsubscribing all, but still made the Mailman web interface inaccessible. How can I make Docker-mailman perform better, to avoid these timeouts. -- Henrik Rasmussen University of Copenhagen

Dump/restore users (with passwords) via API

List description as sender
by Henrik Rasmussen Sept. 26, 2018

Sept. 26, 2018

When receiving a mail from Mailman 3, the From: User name is the description of the list, like From: Long desription of the list for all members of certain project <project(a)lists.example.com>. Starting to get old, I recall something about a discussion we once had on http://mail.python.org/pipermail/mailman-users/, but I don't recall the reason for this and I can't find the discussion, so it might be something I dreamed. What was the reason for implementing this? And could it be a selectable choise in Mailman 3?

Text encoding problem, preapproved header
by Thor Atle Rustad Sept. 20, 2018

Sept. 20, 2018

Mailman 3.2. I send a message to the list with some national characters (æøå ÆØÅ), and everything shows up fine. Then I send the same message using pseudo-header approved: with the list password. This messes up the character encoding, so that instead I get (=C3=A6=C3=B8=C3=A5 =C3= =86=C3=98=C3=85) I experience the problem when I send or receive with Gmail web client, however, when using the Claws-mail (an ordinary mail client) to pick up from my gmail account, the contents is shown correctly. Any suggestions?

Rejection based on total message size including attachments
by leith＠khimaira.com Sept. 20, 2018

Sept. 20, 2018

As a web hosting provider I have searched and searched for a way to limit the total size of messages posted to all lists. We have moderators who just can't get it through their heads to limit the size of attachments. One list today distributed a 6 mb pdf to over 700 recipients. I have found information on creating a custom handler and some old and brief logic on limiting max_message_size from Mr. Sapiro. Would anyone who has developed a custom handler to reject messages based on total size, mind sharing the full file? If so, could you also state where the handler was positioned in the chain of handlers. Thank you for your time.

Set domain inactive / archive import from other domain.
by Johannes Winter Sept. 19, 2018

Sept. 19, 2018

Dear list, we've migrated a list from another domain and would like to keep the archives. Hyperkitty doesn't recognize the emails in the mbox archive during import due to the other domain name. As a workaround we thought of creating a placeholder list with the original and than import the mbox. But actually I don't like to have dysfunctional lists in the domain list. Is it possible to set domains invisible? Or is there a switch to import a list from another domain? Best regards, Johannes Winter

Counter-intuitive header filter processing
by Jonas Meurer Sept. 18, 2018

Sept. 18, 2018

Hello, it seems like the way mailman3 processes header filters is a bit counter-intuitive. With a header filter (HeaderMatch) like the following: header => from pattern => .*(a)freesources.org chain => accept I expect mails from *(a)freesources.org to be accepted regardless of the default message acceptance settings. Apparently, that's not the case. If the default message acceptance setting for members is set to "reject", then mails from *(a)freesources.org get rejected even though the header filter says "accept". In other words, the default message acceptance action seems to overrule any header filters. Is this expected behaviour? Kind regards jonas

Using as a forum
by tokyoprogressive＠mailbox.org Sept. 18, 2018

Sept. 18, 2018

Our group of 30 plus people have the perennial problem in MM II of not checking previous messages before replying. A second problem is starting a new topic rather than responding to a message in the same topic, which makes searching even harder. I previously suggested a forum or something like Stack or Flock. People had no interest in a Word Press forum yet moan about the inefficiency of a list, also it is something new and involves leaving email. Stack and Flock make it hard to require all to be a member of all topics in their free versions. Then it occurred to me, the threaded view in Mailman III looks good and could help us nudge people back on topic. Am I being too optimistic. It is a closed group only open to people we approve. I would like to migrate to MM III but lack the technical skills to fo this? Anyone who could do this for a fee? We probably do not need to bring in the old topics. (I guess there us no way like a forum to limit the topics but at least we could keep things on track). Thanks Paul Arenson Japan Association for Language Teaching Sent from my iPhone

How to connect mailman into existing postfix server
by Hagen Bauer Sept. 16, 2018

Sept. 16, 2018

Hi to all, I am trying to setup mailman3 with the Docker Image. Everythings works relative nicely but I am blocked by the Postfix integration part. I have a small postfix server that is delivering mails to known domains and an alias map. The standard use case assumes that the external postfix is only routing mails to the mailman lmtp. If I do this all my old users are recected. I am looking for an example(s) to integrate mailman into a Postfix configuration as an additional target for postfix. Any hints Regards Hagen

Stability issues
by schultmc＠cinlug.org Sept. 14, 2018

Sept. 14, 2018

We're currently piloting Mailman3 to replace a failing Ecartis installation. We've had to push back our go live date several times due to stability issues with our Mailman 3 installation. We currently have Mailman core 3.2.0 running on Red Hat Enterprise Linux 7.5 with 2 vCPUs, 8GB RAM and 25GB swap space. Occasionally, we see mailman become unresponsive both via the REST API and the web UI. We haven't seen anything glaring in the logs but would be happy to check further. I know Mailman 3 powers many large lists and would appreciate any performance, stability and tuning information that can be provided.

Did I do something wrong here? Is there probably a bug in my python environment? Are there any config options that I should set to avoid this huge memory footprint?

Here is the mailman.log: Sep 07 15:25:39 2018 (32) REST request handler error: Traceback (most recent call last): File "/usr/local/lib/python3.6/wsgiref/handlers.py", line 137, in run self.result = application(self.environ, self.start_response) File "/usr/local/lib/python3.6/site-packages/mailman/database/transaction.py", line 50, in wrapper rtn = function(*args, **kws) File "/usr/local/lib/python3.6/site-packages/mailman/rest/wsgiapp.py", line 214, in __call__ return super().__call__(environ, start_response) File "/usr/local/lib/python3.6/site-packages/falcon/api.py", line 244, in __call__ responder(req, resp, **params) File "/usr/local/lib/python3.6/site-packages/mailman/rest/post_moderation.py", line 160, in on_get resource = self._make_collection(request) File "/usr/local/lib/python3.6/site-packages/mailman/rest/helpers.py", line 159, in _make_collection for resource in collection] File "/usr/local/lib/python3.6/site-packages/mailman/rest/helpers.py", line 159, in <listcomp> for resource in collection] File "/usr/local/lib/python3.6/site-packages/mailman/rest/post_moderation.py", line 150, in _resource_as_dict resource = self._make_resource(request.id) File "/usr/local/lib/python3.6/site-packages/mailman/rest/post_moderation.py", line 77, in _make_resource resource['msg'] = msg.as_string() File "/usr/local/lib/python3.6/site-packages/mailman/email/message.py", line 54, in as_string value = email.message.Message.as_string(self) File "/usr/local/lib/python3.6/email/message.py", line 158, in as_string g.flatten(self, unixfrom=unixfrom) File "/usr/local/lib/python3.6/email/generator.py", line 116, in flatten self._write(msg) File "/usr/local/lib/python3.6/email/generator.py", line 181, in _write self._dispatch(msg) File "/usr/local/lib/python3.6/email/generator.py", line 214, in _dispatch meth(msg) File "/usr/local/lib/python3.6/email/generator.py", line 243, in _handle_text msg.set_payload(payload, charset) File "/usr/local/lib/python3.6/email/message.py", line 315, in set_payload payload = payload.encode(charset.output_charset) LookupError: unknown encoding: _iso-2022-jp$esc

confusing contents of database (data corruption?)
by Dmitry Makovey Sept. 7, 2018

Sept. 7, 2018

I'm troubleshooting slowness and issues in our mailman (container-based) setup. (See also "ORM exceptions" thread) And I've come across really odd contents of DB: mailmandb=# select * from address, (select email, count(email) as instances from address group by email) as emails where emails.instances>1 and emails.email=address.email ; -[ RECORD 1 ]--+---------------------------------------------- id | 1001 email | some_person(a)some.org _original | Some_Person(a)some.org display_name | Some Person verified_on | registered_on | 2018-07-02 03:23:18.761679 user_id | 22543 preferences_id | 146541 email | some_person(a)some.org instances | 2 -[ RECORD 2 ]--+---------------------------------------------- id | 1002 email | some_person(a)some.org _original | display_name | verified_on | registered_on | 2018-07-02 03:23:19.036667 user_id | preferences_id | 146543 email | some_person(a)some.org instances | 2 mailmandb=# select * from member where address_id in (1002,1001); -[ RECORD 1 ]-----+------------------------------------- id | 73682 _member_id | f4cdxxxx-5c64-xxxx-9ac8-1f5xxxxa0f1c role | 4 list_id | mylist.lists.here.stanford.edu moderation_action | address_id | 1002 preferences_id | 146544 user_id | so: 1. address for the same email gets created twice 2. membership references "empty" address 3. membership does not reference proper user 4. preferences_id in all 3 records are different is there a documentation on the DB contents someplace? I feel like our mailman instance slowness is related to DB content but cleaning up that content seems to be risky at best. -- Sr System and DevOps Engineer SoM IRT

message file gone, but exists in database?
by Thor Atle Rustad Sept. 6, 2018

Sept. 6, 2018

I'm investigating some problems, and in the process I want to delete some messages. First, listing all messages: >>> messages = list(message_store.messages) Traceback (most recent call last): File "<console>", line 1, in <module> File "/usr/local/lib/python3.6/site-packages/mailman/model/messagestore.py", line 117, in messages yield self._get_message(row) File "/usr/local/lib/python3.6/site-packages/mailman/model/messagestore.py", line 95, in _get_message with open(path, 'rb') as fp: FileNotFoundError: [Errno 2] No such file or directory: '/opt/mailman/var/messages/5X/7W/5X7WMWNORTGVNB6KVWTHHOI2VF2BEQ7K' Since this message should not exist in database, I try to delete it: >>> message_store.delete_message('5X7WMWNORTGVNB6KVWTHHOI2VF2BEQ7K') >>> commit() >>> messages = list(message_store.messages) Traceback (most recent call last): File "<console>", line 1, in <module> File "/usr/local/lib/python3.6/site-packages/mailman/model/messagestore.py", line 117, in messages yield self._get_message(row) File "/usr/local/lib/python3.6/site-packages/mailman/model/messagestore.py", line 95, in _get_message with open(path, 'rb') as fp: FileNotFoundError: [Errno 2] No such file or directory: '/opt/mailman/var/messages/5X/7W/5X7WMWNORTGVNB6KVWTHHOI2VF2BEQ7K' However, it continues to exist in mailman's mind I also cannot delete messages that actually exist. For instance, I find a message in Postorius that I want to delete. I look at the headers and then run >>> message_store.delete_message('6XFISRRFY74NJEE4FTRNWOA2KGKDBZ3T') >>> commit() After that, the message continues to live, both in postorius and as a file: bash-4.3# ls 6XFISRRFY74NJEE4FTRNWOA2KGKDBZ3T What is wrong?

ORM exceptions

I'm tracing slowness of mailman in our infrastructure, and came across ORM exception: Traceback (most recent call last): File "/usr/local/lib/python3.6/site-packages/sqlalchemy/orm/query.py", line 2837, in one ret = self.one_or_none() File "/usr/local/lib/python3.6/site-packages/sqlalchemy/orm/query.py", line 2816, in one_or_none "Multiple rows were found for one_or_none()") sqlalchemy.orm.exc.MultipleResultsFound: Multiple rows were found for one_or_none() During handling of the above exception, another exception occurred: Traceback (most recent call last): File "/usr/local/lib/python3.6/wsgiref/handlers.py", line 137, in run self.result = application(self.environ, self.start_response) File "/usr/local/lib/python3.6/site-packages/mailman/database/transaction.py", line 50, in wrapper rtn = function(*args, **kws) File "/usr/local/lib/python3.6/site-packages/mailman/rest/wsgiapp.py", line 214, in __call__ return super().__call__(environ, start_response) File "/usr/local/lib/python3.6/site-packages/falcon/api.py", line 244, in __call__ responder(req, resp, **params) File "/usr/local/lib/python3.6/site-packages/mailman/rest/members.py", line 365, in on_post return self._find(request, response) File "/usr/local/lib/python3.6/site-packages/mailman/rest/members.py", line 389, in _find okay(response, etag(resource._make_collection(request))) File "/usr/local/lib/python3.6/site-packages/mailman/rest/helpers.py", line 159, in _make_collection for resource in collection] File "/usr/local/lib/python3.6/site-packages/mailman/rest/helpers.py", line 159, in <listcomp> for resource in collection] File "/usr/local/lib/python3.6/site-packages/mailman/rest/members.py", line 72, in _resource_as_dict user = member.user File "/usr/local/lib/python3.6/site-packages/mailman/model/member.py", line 128, in user else getUtility(IUserManager).get_user(self._address.email)) File "/usr/local/lib/python3.6/site-packages/mailman/database/transaction.py", line 85, in wrapper return function(args[0], config.db.store, *args[1:], **kws) File "/usr/local/lib/python3.6/site-packages/mailman/model/usermanager.py", line 88, in get_user return addresses.one().user File "/usr/local/lib/python3.6/site-packages/sqlalchemy/orm/query.py", line 2840, in one "Multiple rows were found for one()") sqlalchemy.orm.exc.MultipleResultsFound: Multiple rows were found for one() is this a known thing and what's the best path for fixing it? -- Sr System and DevOps Engineer SoM IRT

log rotation
by Dmitry Makovey Sept. 6, 2018

Sept. 6, 2018

I've been looking for a while and cannot find any information regarding log rotation for Mailman3. We're running containerized deployment which complicates the matter slightly, but having "some" approach for log rotation would be helpful. So before I dig into the code looking for SIGUSR1 or SIGHUP handlers can someone point me to a proper documentation for log management with MM3 ? -- Sr System and DevOps Engineer SoM IRT

ARC
by David Krantz Aug. 30, 2018

Aug. 30, 2018

Hi, I just found out that gmail uses ARC (sometimes, at least). Is there support for that in Mailman 3? Without having had the time (yet) to read about in depth it it seems as if ARC is intended to solve at least some of the problems that mail lists have with DKIM. Probably causes others... It might be that no support really is needed in mailman so that just milters in sendmail, postfix etc. might do the trick. regards // David

Migration advice
by Quanah Gibson-Mount Aug. 29, 2018

Aug. 29, 2018

Hi, I'm looking at migrating from an old server running mailman 2.1.15 (Debian wheezy) to a new Ubuntu 18.04 LTS system. I'd like to upgrade to mailman3 as a part of this migration. I was reading the migration docs (<http://docs.mailman3.org/en/latest/migration.html>), which seem to require both mailman2 and mailman3 be installed concurrently on the same system. Is that correct, or can I rsync the mailman2 list information onto the new server without mailman2 itself being present, and import from there? Thanks!
