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

[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. 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
