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?

Loops back to myself
by David Krantz Jan. 12, 2024

Jan. 12, 2024

Hi, I have a problem with my Mailman 3-setup. The symptom is that postfix rejects non-existing addresses for my list domains with <adr(a)example.com>: mail for example.com loops back to myself What I guess happens happens is that postfix for some reason accepts the mail as it is for a relay domain and finds that it is not deliverable locally as the address does not exist locally and then tries to relay it on to the appropriate MX server, which is itself and then fails and generates a bounce message. This is a bit annoying as I have set up postfix to only accept valid addresses. I have set the transport_maps, local_recipient_maps and relay_domains to the files generated by MM3. I run an older version of MM3 (3.0) but prefer to fix this without upgrading as upgrading is a relatively big undertaking. This is mostly a backscatter problem for spam I guess. Any ideas of very simple and easy to forget things that I've probably missed? Cheers // David

Apache Conf
by Guiseppin Thomas July 26, 2022

July 26, 2022

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.

[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

Mailman 3.2.0 Hyperkitty fulltext index error
by Marvin Gülker July 31, 2020

July 31, 2020

Hi, I've just upgraded to Mailman 3.2.0 (finally everything Python 3 now, thanks!) and it appears to work. However, there's a repeating error message in mailman-suite's logfile for Hyperkitty that looks like this: ERROR 2018-07-12 14:28:33,895 2742 hyperkitty.lib.utils Failed to update the fulltext index: ord() expected a character, but string of length 0 found Traceback (most recent call last): File "/home/mailman/env3/lib/python3.5/site-packages/hyperkitty/lib/utils.py", line 179, in run_with_lock fn(*args, **kwargs) File "/home/mailman/env3/lib/python3.5/site-packages/hyperkitty/search_indexes.py", line 115, in update_index update_cmd.update_backend("hyperkitty", "default") File "/home/mailman/env3/lib/python3.5/site-packages/haystack/management/commands/update_index.py", line 276, in update_backend last_max_pk=max_pk) File "/home/mailman/env3/lib/python3.5/site-packages/haystack/management/commands/update_index.py", line 97, in do_update backend.update(index, current_qs, commit=commit) File "/home/mailman/env3/lib/python3.5/site-packages/haystack/backends/whoosh_backend.py", line 178, in update self.setup() File "/home/mailman/env3/lib/python3.5/site-packages/haystack/backends/whoosh_backend.py", line 126, in setup self.index = self.storage.open_index(schema=self.schema) File "/home/mailman/env3/lib/python3.5/site-packages/whoosh/filedb/filestore.py", line 176, in open_index return indexclass(self, schema=schema, indexname=indexname) File "/home/mailman/env3/lib/python3.5/site-packages/whoosh/index.py", line 421, in __init__ TOC.read(self.storage, self.indexname, schema=self._schema) File "/home/mailman/env3/lib/python3.5/site-packages/whoosh/index.py", line 632, in read check_size("int", _INT_SIZE) File "/home/mailman/env3/lib/python3.5/site-packages/whoosh/index.py", line 626, in check_size sz = stream.read_varint() File "/home/mailman/env3/lib/python3.5/site-packages/whoosh/filedb/structfile.py", line 191, in read_varint return read_varint(self.read) File "/home/mailman/env3/lib/python3.5/site-packages/whoosh/util/varints.py", line 102, in read_varint b = ord(readfn(1)) TypeError: ord() expected a character, but string of length 0 found The error repeats every minute, so I suppose it comes from the minutely cronjob.

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.

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?

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

delete examples.com site
by enrique.terrazas＠utsa.edu July 9, 2019

July 9, 2019

Hello, I've been working on setting up Mailman3 on a RHEL 7.5 vm using the guides and documentation found here: http://docs.mailman3.org/en/latest/index.html https://mailman.readthedocs.io/en/latest/README.html http://docs.mailman3.org/projects/postorius/en/latest/index.html http://docs.mailman3.org/projects/mailmanclient/en/latest/README.html https://hyperkitty.readthedocs.io/en/latest/index.html https://gitlab.com/mailman/mailman-hyperkitty nginx is serving the Django applications via uwsgi. I was able to get mailman, postorius + hyperkitty, running and test sending out email verifications. In an attempt to set the default domain to something other than example.com I deleted the site: example.com, I did have another site. Unfortunately, this seems to have broken the Django applications. At the moment I am preparing to delete the virtual environment and set things up again. Unless there is something that can be done in the current virtual environment to "reset" things back to start. I was also running into an issue where the verification emails were successfully sent out. The url to verify the email looks like this: http://my.domain.com:8000/accounts/confirm-email/xxxxxxxxxxxx/ Replacing my.domain.com with the domain I added. How can I get the outgoing verification emails to not reference port 8000? If I take that same link and remove the port, I get the desired page. Port 8000 is blocked at our sites permitter firewall, I don't necessarily want to open it. I'd rather the URL just obfuscate the port and send it to https... Thank you in advance for your attention and assistance. Best regards, Enrique J. Terrazas

Hyperkitty Archives - Sidebar years/months
by Enrique Terrazas June 20, 2019

June 20, 2019

Hello, I’m going through importing archives from mm2 to mm3. One of the lists I’ve imported has messages going back to 11/2013. I was able to successfully import the lists settings using: mailman import21 lists(a)domain.com<mailto:lists@domain.com> /path/to/list/config.pck This successfully imported lists owners, moderators, subscribers, & settings. I then imported the messages with the following command: python /path/to/manage.py hyperkitty_import -l list(a)domain.com<mailto:list@domain.com> /path/to/list.mbox —since 10/01/2013 I used that date because it is older than the first message sent to the list: 11/13/2013 And followed that up with the update index command: python /path/to/manage.py update_index_one_list list(a)domain.com<mailto:list@domain.com> This successfully imported all the messages from 11/13/2013 through 09/30/2018. Here is where I’m facing two issues: * Messages from October 2018 were not imported * The sidebar only shows the year 2018. Fdasfds If I modify the URL to go to https://my.domain.org/hyperkitty/list/list@domain.com/2013/11 the archived emails show up fine. October 2018 shows two test messages I’ve sent but not any of the messages from October 2018 that should have been imported. Is there something additional that needs to be done to show the previous years and months in the sidebar? Thanks, Enrique

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-1:4 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.

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

Templates
by David Krantz Dec. 19, 2018

Dec. 19, 2018

Hi. How do I set a template for one specific list? I want one list to have a special footer template. I have tried updating the database (template table) without effect so apparently the database is not used for templates or some kind of fallback is used to set it to the generic footer. Of course I also tried to restart mailman after that operation to try to rule out any caching-related problem. I want to use a file://-path as that is the least painful way of doing it. I also would like a solution to place a file in a special location. My current templates are in a .../var/templates/site/en/ structure with names like list:member:generic:footer.txt Cheers // David

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? At first, I thought that the DKIM signature verification caused Exim to be dropping the autoresponse. So I set `DISABLE_DKIM_VERIFY=true` in exim, but still no autoresponse. Here are the exim logs after the sender sends the email ``` ^[[A2018-10-19 14:58:40 1gDWEa-0004Ww-QF <= shadiakiki1986(a)gmail.com H=mail-vs1-f53.google.com [209.85.217.53] P=esmtp K S=2410 id=CACk+RNvnfS+e+Uh-OSKjPB8oe+b1=efAJ6BSrc51jz_h9sVoFQ(a)mail.gmail.com 2018-10-19 14:58:40 1gDWEa-0004Ww-QF => 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 14:58:40 1gDWEa-0004Ww-QF Completed 2018-10-19 14:58:42 1gDWEc-0004Wz-R1 <= quotations-bounces(a)mailman3.akikieng.com H=ip-172-19-199-2.us-west-2.compute.internal [172.19.199.2] P=esmtp S=3841 id=CACk+RNvnfS+e+Uh-OSKjPB8oe+b1=efAJ6BSrc51jz_h9sVoFQ(a)mail.gmail.com 2018-10-19 14:58:42 1gDWEc-0004Wz-R1 => shadi(a)akikieng.com R=smarthost T=remote_smtp_smarthost H=smtp.mailgun.org [54.69.10.167] 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 14:58:42 1gDWEc-0004Wz-R1 Completed ``` 2. is my understanding correct in reading these logs that there is nothing here about an autoresponse?
