Find a smtp server to send out emails
by Leon March 12, 2025

March 12, 2025

Hi, This problem is not caused by mailman, but I still want to give it a shot here. I'm hosting a mailing list on top of mailman3. Emails are supposed to be sent out by AWS ses. However, ses requires that sender address must be verified, which leads to a problem that emails sent by subscribers to mailing list cannot be sent to other subcirbers, since their addresses are not verified. And it is impossible to verified every subscriber. Are there smtp service providers allowing unverified email address to send out emails, or do I have other solutions? Thanks. -- Best wishes, Leon

[MM3-users]Is it possible to grant all users the ability to Create List
by Carrie Knox July 13, 2021

July 13, 2021

Hello, Our company is evaluating mailman3 as an option for company internal list serving. One of the requirements is that anyone with access to the list server be allowed to create and manage lists. Is this possible? If so, how? Is there a "create list" role that can be added for all registered users? Thanks

MM3 shunting mails
by Anders Nilsson Jan. 3, 2020

Jan. 3, 2020

I'm running a Mailman 3.1.0 installation on a CentOS 7 machine. Using RPMs from https://repos.fedorapeople.org/repos/abompard/hyperkitty/el-7/x86_64/ I do have problems with some lists occasionally going into some kind of shunt mode, where alla mails sent to them gets shunted. In the Mailman log I get entries for each shunted email: Mar 17 11:54:11 2017 (6217) Uncaught runner exception: Multiple rows were found for one_or_none() Mar 17 11:54:11 2017 (6217) Traceback (most recent call last): File "/usr/lib/python3.4/site-packages/mailman/core/runner.py", line 171, in _one_iteration self._process_one_file(msg, msgdata) File "/usr/lib/python3.4/site-packages/mailman/core/runner.py", line 264, in _process_one_file keepqueued = self._dispose(mlist, msg, msgdata) File "/usr/lib/python3.4/site-packages/mailman/runners/pipeline.py", line 37, in _dispose process(mlist, msg, msgdata, pipeline) File "/usr/lib/python3.4/site-packages/mailman/core/pipelines.py", line 53, in process handler.process(mlist, msg, msgdata) File "/usr/lib/python3.4/site-packages/mailman/handlers/rfc_2369.py", line 121, in process process(mlist, msg, msgdata) File "/usr/lib/python3.4/site-packages/mailman/handlers/rfc_2369.py", line 70, in process archiver_set = IListArchiverSet(mlist) File "/usr/lib/python3.4/site-packages/zope/component/hookable.py", line 33, in __call__ return self.__implementation(*args, **kw) File "/usr/lib/python3.4/site-packages/zope/component/_api.py", line 156, in adapter_hook return sitemanager.queryAdapter(object, interface, name, default) File "/usr/lib64/python3.4/site-packages/zope/interface/registry.py", line 348, in queryAdapter return self.adapters.queryAdapter(object, interface, name, default) File "/usr/lib/python3.4/site-packages/mailman/database/transaction.py", line 85, in wrapper return function(args[0], config.db.store, *args[1:], **kws) File "/usr/lib/python3.4/site-packages/mailman/model/mailinglist.py", line 607, in __init__ ListArchiver.name == archiver_name).one_or_none() File "/usr/lib64/python3.4/site-packages/sqlalchemy/orm/query.py", line 2733, in one_or_none "Multiple rows were found for one_or_none()") sqlalchemy.orm.exc.MultipleResultsFound: Multiple rows were found for one_or_none() Mar 17 11:54:11 2017 (6217) SHUNTING: 1489748051.1949184+7a59df19c81493cb419306d620376efc0e381819 And so far my Google-fu hasn't been good enough to give me any useful answers to why this happens. If I dump one of the pickles using qfile I cannot see any complaints. Most of the times, if I remove and recreate a failing list and run unshunt the shunted emails get processed and sent. Anyone seen something similar?

Auth question
by David Krantz Jan. 8, 2019

Jan. 8, 2019

Hi, I have of course activated password login as it was not possible to get the provider based logins to work (might be but not worth the time for me right now). Is there any way for an user to request a new password when it is forgotten? I presume that the Persona login is removed now. I cannot hide it in my version or at least I do not know how. cheers // David

Any good ideas on how to troubleshoot django allauth
by David Krantz April 27, 2017

April 27, 2017

Hi again. Allauth works for me... sometimes... For google logins it works most of the time. For facebook it almost never works. When it does not work, I get an error page with the error "An error occurred while attempting to login via your social network account." (or the equivalent in my locale). If I then reload the page, I get logged in! In some cases I get the error and the little green popup saying that I am logged in at the same time. Strange. So... If there is any documentation for how to set up or how to troubleshoot django allauth I am all ears (eyes, really). I have tested the "missing howto..." and updated version of that without enough success. Cheers // David The only thing I find is in the Apache log: (I have removed all cryptovalues and other things that should be uninteresting to others) [LOCAL_IP] - - [19/Apr/2017:00:00:39 +0000] "GET /accounts/facebook/login/?process=login&next=%2Farchives%2F HTTP/1.1" 302 706 "https://lists.example.com/accounts/login/?next=/archives/" "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/52.0.2743.116 Safari/537.36 Edge/15.15063" [LOCAL_IP] - - [19/Apr/2017:00:00:53 +0000] "GET /accounts/facebook/login/callback/?code=[LONG CRYPTO-LOOKING STRING] HTTP/1.1" 200 2129 "https://www.facebook.com/login/reauth.php?app_id=[MY_APP_ID_I_THINK]&signed…" "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/52.0.2743.116 Safari/537.36 Edge/15.15063"

Patch/kludge suggestion and a question on adding accepted addresses
by David Krantz April 25, 2017

April 25, 2017

Hi. I found out that I had a broken email in one of my held messages queues). That gave a HTTP 500 error although that should be fixed . After some digging I found out that where the error occured. I'd suggest adding a catch for AttributeError similar to the one for KeyError in _HeldMessageBase in rest/post_moderation.py. It solved my immediate problem at least. I run the version from git with the tag 263711b3b7988c7c474e3b8952dc7e0f02f04fa2 The message causing this was probably one where I had sent a minimal email via telnet to the SMTP port and forgot the MessageID-header or something similarily silly. But it prevented me from seeing the held messages-list in postorius. I have another question: In the old mailman you could add accepted senders without adding them to the list. Is that possible in Mailman 3/Postorius? cheers. // David

Fwd: Incoming command emails (i.e. listname-leave) routed to list itself
by Abhilash Raj April 22, 2017

April 22, 2017

The updated documentation[1] should fix your problem. The basic gist of the problem is that the exim configuration on the older documentation is missing a critical part. Exim4 by default strips off any prefixes/suffixes when delivering mail to the mailman, which causes mailman to post all the messages to mailing list instead of processing them as commands. `rcpt_include_affixes = true` Adding the above line to the transport fixes that problem.

Incoming command emails (i.e. listname-leave) routed to list itself
by Mark Lindsay April 21, 2017

April 21, 2017

Hi mailman-users, I'm new to Mailman 3 and Mailman in general, but I've got it up and running, and my external app is communicating quite well with the administrative REST API. Here's the only problem I haven't been able to figure out: Say I have a list called "potato." List members can post to the list by emailing potato(a)lists.mydomain.org. This works fine. However, incoming mail for command addresses (e.g. potato-leave(a)lists.mydomain.org) is routed to the list too. The command email gets sent out to all members, as if the user who wanted to unsubscribe had just written to potato(a)lists.mydomain.org. This is also the case with the potato-request(a)lists.mydomain.org address. I am using exim4 on Ubuntu. I followed the instructions here: http://mailman.readthedocs.io/en/release-3.0/src/mailman/docs/MTA.html. The only change I had to make to the exim4 config files in the readthedocs instructions was in this line: MM3_LISTCHK=MM3_HOME/lists/${local_part}@${domain} I had to change it to: MM3_LISTCHK=MM3_HOME/lists/${local_part}.${domain} That is how the subdirectories are named in my lists directory. e.g. potato.lists.mydomain.org. If I use the exact MM3_LISTCHK value from readthedocs, I get 550 Unrouteable bounces. Here are some baffling lines from /var/log/exim4/mainlog from the incoming potato-leave(a)lists.mydomain.org email: 2017-04-21 00:25:03 1d1MNj-0007OQ-5r DKIM: d=nervous-org.20150623. gappssmtp.com s=20150623 c=relaxed/relaxed a=rsa-sha256 [verification succeeded] 2017-04-21 00:25:03 1d1MNj-0007OQ-5r <= redacted(a)nervous.org H= mail-qk0-f170.google.com [209.85.220.170] P=esmtp S=2466 id= CABPy5zyQtJHXtCgrN37GHCUOjuo3J=DO_j0ZD03zm8gk+4shww(a)mail.gmail.com 2017-04-21 00:25:03 1d1MNj-0007OQ-5r => potato(a)lists.mydomain.org < potato-leave(a)lists.mydomain.org> R=mailman3_router T=mailman3_transport H=localhost [127.0.0.1] C="250 Ok" 2017-04-21 00:25:03 1d1MNj-0007OQ-5r Completed Why does it say `potato(a)lists.mydomain.org <potato-leave(a)lists.mydomain.org >`? I think this is actually an exim4 problem, so if the solution is to just switch to postfix, then I will definitely do that. But I'm just asking in case someone had a similar issue with exim4 and was able to work through it. Thanks a lot, Mark

Memory footprint
by David Krantz April 19, 2017

April 19, 2017

Hi. Now running mailman 3 I am a bit surprised that the memory footprint is so large. I count to 13 processes with each a virtual space of 160-250MB and a reserved space of about 50MB each. Not much, but quite much to run on smaller cloud instances which generally have limited memory. This is (a lot) more than the corresponding postgres installation uses, Is this normal? regards // David

Installing MM3 requires Django<1.11
by Henrik Rasmussen April 12, 2017

April 12, 2017

Two questions regarding Mailman 3 installation: 1) The Mail server setup at http://docs.mailman3.org/en/latest/devsetup.html#set-up-a-mail-server isn't described yet. Instead it refers to https://docs.djangoproject.com/en/1.10/topics/email/#topic-email-backends, but it doesn't say which file I have to change. According to https://www.webforefront.com/django/setupdjangoemail.html the file is called settings.py, but the only settings.py I can find at this stage is the /opt/mailman/postorius/example_project/settings.py file. According to http://docs.mailman3.org/en/latest/devsetup.html#set-up-and-run-postorius, "Postorius and HyperKitty both come with example_project directories with basic configuration so you can try them out. For this tutorial, however, we'll be using a project that combines both instead.". In what file should I change the mail settings then? 2) While installing Hyperkitty*) I got the error message "Django 1.11rc1 is installed but Django<1.11 is required by {'django-haystack'}". As I have slavishly followed the installation guide including http://docs.mailman3.org/en/latest/devsetup.html#set-up-django-mailman3, I wonder why a non-supported Django version was installed. *) http://docs.mailman3.org/en/latest/devsetup.html#set-up-and-run-hyperkitty Regards Henrik

Deploying mailman3 using containers
by Abhilash April 10, 2017

April 10, 2017

Hi All, I have been working for the past two weeks on trying to create a solution to easily deploy Mailman 3 in production. For those interested, you can find the instructions about how to use my work at http://asynchronous.in/docker-mailman/. I have tried to document the process as much as possible. This is still a work in progress, but I have a working deployment[1] using these containers. I try to keep the deployment updated with the github repo, but there is no automated deploy happening there so sometimes it gets out of sync. While this is aimed to finally become a production ready method to deploy mailman 3, it is still not there. All I can say at this point is that it works. I have tried my best to document everything and I keep updating the documentation whenever I feel anything needs more clarity. I would love some feedback to improve the process or documentation. You can open issues on the github repo[2]. Currently, container images are built from the master branch of the gitlab repos and are thus not branded as stable. I am waiting for 3.1 release to add a stable tag to the images. [1]: https://mail.araj.me/ [2]: https://github.com/maxking/mailman -- thanks, Abhilash Raj
