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?

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

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

How to get Mailman core to provide more debug info in a running environment
by Henrik Rasmussen Jan. 3, 2019

Jan. 3, 2019

Docker-mailman 0.1.1 I am using Mailman 3.1 in production and I am trying to debug a problem[1] so I tried to setting Mailman to provide more debug info in the smtp.log file[2]. I might have been doing it wrong, but in the mailman-extra.cfg I set [logging.smtp-failure] path: smtp.log and restarted Mailman, which stopped incoming mails until removing the added section. What is the correct way to get Mailman to provide more debug info in the smtp.log 1) https://lists.mailman3.org/archives/list/mailman-users@mailman3.org/thread/… 2) http://mailman.readthedocs.io/en/latest/src/mailman/config/docs/config.html… Henrik Rasmussen

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
