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

Does Mailman 3 have something similar to https://www.msapiro.net/scripts/last_post.py displaying the last post time for a list or all lists?

[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

Default values for new lists
by Sten Aus Jan. 11, 2020

Jan. 11, 2020

Hi I haven't found out where I could choose or edit default list values (when creating new list). For example I would like that all new lists would be with *private archive* (and change this when it is needed). This is great that I can choose not to advertise list in Index (which I can choose from list creation interface) but I would like to choose other options too. Right now only solution is to create list and then choose Archiving and then select "private archives". Another thing is that I would like to choose default subscription policy to "Moderate". If anyone has encountered this problem, let me know! All the best Sten

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?

bounces with empty message-id
by Peter Münster Dec. 12, 2019

Dec. 12, 2019

Hi, It seems, that mailman bounces the bounces, so that the list-owner never sees them: --8<---------------cut here---------------start------------->8--- postfix/smtpd[12002]: connect from out04.smtpout.orange.fr[193.252.22.213] postfix/smtpd[12002]: 879D6F12E8: client=out04.smtpout.orange.fr[193.252.22.213] postfix/cleanup[11841]: 879D6F12E8: message-id=<> postfix/qmgr[10092]: 879D6F12E8: from=<>, size=4048, nrcpt=1 (queue active) postfix/smtpd[12002]: disconnect from out04.smtpout.orange.fr[193.252.22.213] ehlo=1 mail=1 rcpt=1 data=1 quit=1 commands=5 postfix/lmtp[11846]: 879D6F12E8: to=<test-bounces(a)my-domain.org>, relay=127.0.0.1[127.0.0.1]:8024, delay=0.05, delays=0.04/0/0/0.01, dsn=5.0.0, status=bounced (host 127.0.0.1[127.0.0.1] said: 550 No Message-ID header provided (in reply to end of DATA command)) postfix/qmgr[10092]: 879D6F12E8: removed --8<---------------cut here---------------end--------------->8--- What could I do please, to get the bounces? I would like to use VERP to identify wrong addresses... TIA for any hints, -- Peter

confirm mail rejected
by Marc Sluiter Sept. 29, 2019

Sept. 29, 2019

Hi, im trying to setup mailman and have an issue: first my environment: - I’m running postfix etc with "mailcow-dockerized": https://mailcow.github.io/mailcow-dockerized-docs/ - I’m running mailman with "docker-mailman": https://asynchronous.in/docker-mailman/ I got almost everything working (with some configuration modifications, see other mail). The only thing which doesn’t work is conformation mails, they are rejected: In the logs I see that postfix is trying both "liste-confirm+extension@domain" and "liste-confirm@domain" for another lookup map of type mysql (so "recipient_delimiter" is working), but not for the mailman map of type regexp. Just a wild guess, I didn't find anything about it: can it be that “recipient_delimiter" doesn't work for “regexp" maps? For now I worked around this issue by manually modifying the confirm regex in "postfix_lmtp” to /^liste-confirm\+.*(a)domain\.tld$/ Does anyone have an idea why the regexp map isn’t working for me and at least 1 other user (see https://gitlab.com/mailman/mailman/issues/401)? Would my workaround be a long term solution which could be implemented in mailman? That would mean that mailman could work independent of the “recipient_delimiter” setting (or do I oversee something?) Thanks and greetings, Marc

Mailman 3 Installation Assistance
by brian＠emwd.com July 26, 2019

July 26, 2019

I am making a serious attempt at installing Mailman 3 using docker. I have a CentOS 7 server setup via Linode. I am using the following documentation to setup a Mailman 3 server: https://xiaoxing.us/2018/01/02/Deploy-Mailman-3-on-AWS-using-Docker/ I have Docker, Postfix, and Nginx installed and working fine. The installation of the Mailman 3 container went fine. However I am getting the following error when I go to test Posterius via shell: curl http://172.19.199.3:8000/postorius/lists/ curl: (7) Failed connect to 172.19.199.3:8000; Connection refused I assume this has something to do with uwsgi which I have no experience with. Appreciate any assistance with getting Mailman 3 up and running. Thanks! Brian Carpenter

Flushing/syncing hyperkitty with mailman
by Eric Abrahamsen June 20, 2019

June 20, 2019

I've got mailman running on Ubuntu 14.04, with systemd service files to govern the mailman and hyperkitty qcluster processes. I notice in the systemctl status call for the qcluster command that there are a bunch of errors like: [Q] ERROR Failed [rebuild_thread_cache_votes] - Thread matching query does not exist. [Q] INFO Process-1:1 processing [rebuild_email_cache_votes] [Q] ERROR Failed [rebuild_email_cache_votes] - Email matching query does not exist. [Q] INFO Process-1:2 processing [rebuild_thread_cache_votes] [Q] ERROR Failed [rebuild_thread_cache_votes] - Thread matching query does not exist. [Q] INFO Process-1:3 processing [rebuild_email_cache_votes] [Q] ERROR Failed [rebuild_email_cache_votes] - Email matching query does not exist. [Q] INFO Process-1:4 processing [rebuild_thread_cache_votes] [Q] ERROR Failed [rebuild_thread_cache_votes] - Thread matching query does not exist. Is there something more I should be doing to sync hyperkitty's database with mailman? I've got the crontab file in place, and that appears to be running without error. Anything else? Thanks, Eric

GDPR - save subscriptions confirmation emails
by contact＠maadix.net May 1, 2019

May 1, 2019

Hi, I am new in the list. I have been looking for this topic in the archives in order to avoid duplicate, but I could not find any thread. According to the new GDPR rules, lists owners need to have a confirmation from subscribers, and this is easy to do with Mailman 3. What I can't figure out is how to save all the confirmation emails received from users. I only see the confirmations commands emails in the logs, Is there another place/way to store them? For GDPR compliance it is important to be able to demonstrate that you received the confirmation, in case you may need it in the future.
