Removing the footer from mailing list messages
by MegaBrutal Dec. 7, 2025

Dec. 7, 2025

Hello, I'm replacing a Postfix virtual_alias_maps distribution list with a GNU Mailman mailing list because there were many bounced messages, as Postfix doesn't care about properly resending e-mails. I want to kind of restoring the same functionality with Mailman, i.e. to be it as transparent as it can be, neither non-members, nor members should see how the list is implemented by Mailman. Therefore, I want to remove the „XX mailing list ...; To unsubscribe send an e-mail to ...” message from the footer of the e-mails. The problem with this is that list members sometimes reply to e-mails from non-members, and might potentially leave the footer in the quote. What I already tried: define a custom template for list:member:regular:footer. The result was that the mailing list stopped operating altogether, no messages passed through until I deleted this template. After I deleted it, all delayed e-mails were forwarded at once. What would be the right way to remove the footer? Best regards, MegaBrutal

One-click unsubscribe?
by Jered Floyd Dec. 7, 2025

Dec. 7, 2025

I'm having a lot of problems with GMail delivery due to lack of "one-click unsubscribe" -- however that is quantified, which is not clear. In particular, there is an issue with the fact that Google ignores dots in email addresses. So I have many (MANY!) subscribers who try to use the List-Unsubscribe header target, but because they are subscribed as "idiotsubscriber(a)gmail.com" rather than "idiot.subscriber(a)gmail.com" (which they have since changed their sender to) they get a reject that they are not subscribed. These people are also far too unobservant to read the footer of every message that reads "You are subscribed as idiotsubscriber(a)gmail.com". Is there any way to provide personalized List-Unsubscribe header links, or have Mailman ignore dots in gmail.com addresses... or... anything? I'm finding reported spam percentages in the Google Postmaster Dashboard exceeding 0.1%, which causes massive delivery blocking to GMail-based subscribers. While I would gladly ban everyone who uses gmail, that sadly accounts for about half of the Internet today and would be incredibly unproductive. Thanks, --Jered

Hyperkitty: Determine the size of an archive
by Frank Richter Dec. 6, 2025

Dec. 6, 2025

Hi, we’d like to inform our list owners of archive enabled lists about the (approximate) size of their archive. In Mailman 2 we used the size of the mbox file. Now how can I determine the size of the archived e-mails of a list in Mailman3 with Hyperkitty? Any ideas? Thanks, Frank -- Frank Richter, Chemnitz University of Technology, Germany

Too Many From Headers
by dap1＠bellsouth.net Dec. 2, 2025

Dec. 2, 2025

I am getting mail bounced from yahoo and gmail smtp servers with this message: 554: Message not accepted due to failed RFC compliance. Too many From headers. See https://senders.yahooinc.com/smtp-error-codes#rfc-compliance-failures What would cause mailman to build too many from headers when distributing email? It appears the from address is repeated 5 times in the from field. I'm guessing it is something in my configuration but what and where?

Finding all held messages
by Peter Chubb Nov. 29, 2025

Nov. 29, 2025

Hi Folks, Is there a way from the Web UI to find all lists with held messages? I'm site owner and admin for a domain; I'd like to see all the held messages for all the lists in that domain, so I can gently encourage moderators to do their jobs .. and to stand in when they're away or otherwise cannot release held messages in a timely manner. To do this I want to see all held messages, and the lists they are meant for. Right now, to see which lists have held messages means clicking on each list name n turn. which can take a long time, even for the couple of dozen lists we have. Peter C

Use own mail server
by johannes.wolf＠kaaw.de Nov. 28, 2025

Nov. 28, 2025

Hi there, we just installed mailman in our internal environment and want to use our own mailserver for sending the mails. Can someone explain which configuration i have to make in my mailman.cfg? I just set smtp_host and smtp_port which seems to work as the mailman server connects to my mailserver but it generates e-mails with blank recipients and headers. Maybe someone can give me a hint? Thanks and regards

How to disable the password reset email, from being sent to an address not in our database?
by mrl＠psfc.mit.edu Nov. 26, 2025

Nov. 26, 2025

Hi - Someone just requested a password reset, for an email address not in the mailman database. Mailman sent a message to them, but the email was invalid. I would like to disable an email from being sent to a user not in the mailman database. How to do this? Thanks. - Mark -------------------------------------------------------------------------------------------- Hello from MIT PSFC Mailing Lists! You are receiving this e-mail because you or someone else has requested a password for your user account. However, we do not have any record of a user with email hwbaCXa(a)zTi.com in our database. This mail can be safely ignored if you did not request a password reset.

can templates be html formatted?
by John Harrison Nov. 26, 2025

Nov. 26, 2025

My goal here is to have as little friction as possible for nontechies to join and participate in an email discussion list. So that means - HTML formatted hyperlinks in all emails including the welcome email to subscribe, unsubscribe, see the archives, etc. - no need for a password ever for anything they'd want to do. - A simple click to subscribe, unsubscribe, see the archives. All hyperlinks. I've been playing with the welcome template and it seems maybe this can't do what I am looking for (html formatting). I'm wondering also why it's doing some sort of soft wrap with line breaks which is breaking longer urls in the template.

Bounce processing HTML
by pashdown＠xmission.com Nov. 25, 2025

Nov. 25, 2025

I'm getting a load of bounce processing for HTML tags. Is there a setting to filter messages through lynx or something to strip out HTML? I'm not sure why a bounce message would be HTML formatted, but ours is not to reason why. Bounce message for a non subscriber: Email b is not a subcriber of (redacted) Bounce message for a non subscriber: Email o:shapedefaults v:ext="edit" spidmax="1026" / is not a subcriber of (redacted) Bounce message for a non subscriber: Email br is not a subcriber of (redacted) Bounce message for a non subscriber: Email i is not a subcriber of (redacted) Bounce message for a non subscriber: Email o:shapelayout v:ext="edit" is not a subcriber of (redacted) Bounce message for a non subscriber: Email mailto:redacted@redacted.com is not a subcriber of (redacted) Bounce message for a non subscriber: Email /xml is not a subcriber of (redacted) Bounce message for a non subscriber: Email head is not a subcriber of (redacted) Bounce message for a non subscriber: Email /title is not a subcriber of (redacted)

Internal Server Error: /mailman3/accounts/fedora/login/
by Alain D D Williams Nov. 20, 2025

Nov. 20, 2025

Twice today I have received many (50+) emails like the one below. Many at about 1pm, then it stopped now I am getting them again. An Internet search does not bring up anything useful. The domain at the start of 'Request URL' varies as does the name of the list (in this example 'announce(a)leavesden.org') The domain of the list is not necessarily the same as the domain at the start of the URL. I can receive several in a minute.

Add an extra option for "Delivery status" for users?
by Thomas Ward Nov. 20, 2025

Nov. 20, 2025

Hello! We have a unique case where we have a user we want to disable for mail receiving, etc. for the reason "Disabled by IT Security Team" but I don't even know if it's possible to add a delivery status that is that custom. I know we have "Disabled" and "Disabled by Owner" but would we be able to add/modify the list to add that option (so that list owners can mark it)? (I say List owners because the ITSec team at a client has 'owner' status by default, without an extra group, but we want to have a dedicated dropdown selection for the ITSec team, even if we just have to duplicate "Disabled by Owner") Thomas

Block members from sending cc's and bcc's
by Cathryn McGuire Nov. 15, 2025

Nov. 15, 2025

Hi everyone, Using Mailman 3 with Affinity web interface and we want to stop our members from sending to cc: or bcc: We've found the Header Filter and cc and bcc appear in it. Tried to configure it to "hold for moderation," but it hasn't worked. Partly because we don't understand what to put in the Pattern input box. I put in cc: because it requires something. Can anyone advise? Cheers, Cathryn

Postfix Hooks and Fetchmail
by dap1＠bellsouth.net Nov. 14, 2025

Nov. 14, 2025

I'm using fetchmail to feed mailman3 and am having a problem with the postfix hooks. My list name is llllllllll(a)ddddddddd.net. However, fetchmail passes the email to lllllllllll@localhost. So I am getting this error in the mail log: Out: 550 5.1.1 <llllllllll@localhost>: Recipient address rejected: User unknown in local recipient table Is there something I need to add to mailman's recipient table, fetchmail or an alias in postfix?

mailman-web migrate error

My django container keeps getting shutdown by oom-killer
by Hirayama, Pat Nov. 13, 2025

Nov. 13, 2025

Greetings, Ok, I just updated the docker containers that are running my Mailman 3 installation over the weekend. mailman-core is now 3.3.10, with mailman-ngnix at 1.28.0, mailman-postfix at 3.10.5-r0 and mailman-django-uwsgi at "latest". I think I have got everything working normally — messages seem to be processed correctly, and I can access the web pages on the web interface. And I have updated various scripts to use --run-as-root until I can get around to reconfiguring mailman-core to use a non-root user. Anyway, since that time, the EC2 instance that the containers are running on becomes "unreachable", to use AWS's parlance. I can restore functionality by rebooting the instance. According to AWS, this is an application or operating system issue, not their instance. Which means auto-recovery doesn't get activated. This always happens overnight, usually after midnight, though one time it was around 10:40. I don't see any crontab entries that correlate. And the after midnight issues don't always happen at the same time, so it seemed unlikely that it was a crontab job that was causing it I finally looked at the host (rather than the logs of each container) and realized that the oom-killer was killing django-admin. As a temporary workaround, I've limited memory on the mailman-django-uwsgi container to 4 GiB (though, since I just did that this morning, I won't know until after midnight (presumably) if it worked or not), and set the RestartPolicy to always. I'm thinking that this points to a memory leak or some kind? I did have to add a bunch of packages to my Dockerfile when I rebuilt the container, since the last build was like 5 years ago, so I suppose it could be that django is just using more memory than it used to, though at the moment, I see that it is around 1 GiB: FROM python:3.12-alpine3.22 RUN apk update && apk add --no-cache --virtual build-deps \ cargo gcc libffi-dev musl-dev && \ apk add --no-cache gettext postgresql-dev sassc build-base pcre-dev python3-dev libc-dev linux-headers && \ pip install --upgrade pip setuptools wheel && \ pip --no-cache-dir install django-haystack==3.3.0 hyperkitty==1.3.12 \ postorius==1.3.13 psycopg2 uwsgi==2.0.25 whoosh && \ apk update && apk del --no-cache build-deps WORKDIR /opt/mailman/mailman-suite/mailman-suite_project USER mail EXPOSE 8000 CMD ["uwsgi", "--ini", "uwsgi.ini"] Any insights, ideas or assistance would be appreciated.

Xapian alternatives

Are there alternative search engines to Xapian that can be used for Mailman 3? I have come to understand that Xapian development stalled in the v2.0 attempt.

custom css?
by jamie＠mayfirst.org Nov. 9, 2025

Nov. 9, 2025

I've installed the mailman3, mailman3-full, mailman3-web, and python3-django-mailman3 packages on Debian trixie. Everything is working - thank you developers! However, I would like to modify how the web pages look (both postorius and hyperkitty). I noticed that the web interface on this server (lists.mailman3.org) looks much nicer than the one showing on my server. For one, on my installed instance, the left and right margins are not set, so content is flush with the edge of the screen. What is the easiest/most maintainable way to add my own css code and/or files to adjust how the web interface is displayed? Is that possible? Thank you! jamie

Cannot issue commands through email
by stonehold＠thedagora.social Nov. 9, 2025

Nov. 9, 2025

Greetings! I've recently deployed mailman3 for my community but have run into a snag -- none of the emails that issue commands (eg., list1-<join>@domain.com, list2-<unsubscribe>@domain.com, etc. etc.) are going through. They keep bouncing back with an undeliverable message. I can create lists and interact with them otherwise just fine. When I join from the web UI I can post and receive to that list. I've been able to troubleshoot the rest so far on my own, but this has me stymied, so any guidance would be greatly appreciated. Thanks in advance! ~Ken

Internal server error instead of web interface
by Christian H. Kuhn Nov. 5, 2025

Nov. 5, 2025

Hi all, https://lists.qno.de/mailman3 shows an internal server error. I followed https://docs.mailman3.org/en/latest/install/virtualenv.html with MariaDB instead of PostgreSQL. Python 3.13.0 pip 25.3 mailman 3.3.11b mailman-web 0.0.10.dev14?g0997bd postorius 1.3.13 Services mailman3, mailmanweb, apache2, uwsgi up and running. uwsgi listens on [::1]:8000, apache2 is configured accordingly. Ports show up in netstat. No errors show in logs. If /mailman3 was a directory, i would have thought of user permission problems. But not with TCP ports. As :8000 is available, i would have thought that there is a problem with uwsgi. Requests arrive there and are processed: [pid: 3185672|app: 0|req: 10/17] ::1 () {28 vars in 409 bytes} [Mon Nov 3 13:24:05 2025] GET /mailman3/ => generated 5038 bytes in 28 msecs (HTTP/1.0 200) 8 headers in 261 bytes (1 switches on core 0) So uwsgi gets the request and delivers data. The problem seems that apache2 does not get the result, and i cannot find any reason. Any help? TIA QNo

"Something went wrong | Mailman REST API not available. Please restart Mailman core.
by Hirayama, Pat Oct. 31, 2025

Oct. 31, 2025

Greetings, Some of my lists have started displaying this behavior — when you try to access the list page(s), you get a page with this message: Something went wrong Mailman REST API not available. Please restart Mailman core. My mailman-core docker container is running, as are mailman-django-uwsgi, mailman-nginx and mailman-postfix. Restarting the containers doesn't change this behavior. Google suggests restarting mailman core. Or that we might not be using the correct account name, password or port. The weird thing is that it is not all lists. Most of them seem to be fine. Which suggests to me that the issue is with a few lists, but not systemwide, so I think my settings in mailman.cfg, settings.py, settings_local.py are likely correct. For the problem lists, I see this in the log: ERROR 2025-10-29 18:38:56,784 7 postorius Mailman REST API not available ERROR 2025-10-29 18:38:56,790 7 django.request Service Unavailable: /postorius/lists/obfuscated.name.lists.fhcrc.org/ ERROR 2025-10-29 18:38:56,790 7 django.request Service Unavailable: /postorius/lists/obfuscated.name.lists.fhcrc.org/ So, Postorius can't communicate with the API, I guess? I look at settings_local.py: MAILMAN_REST_API_URL = 'http://mailman-core:8001' I believe 8001 is the default, and since I haven't specified one in the [webservice] section of mailman.cfg, I'm assuming 8001 is correct (plus, it works for other lists). There are a few messages waiting for moderator approval — otherwise, I'd probably try just deleting the list and recreating it. Anyone have any suggestions on what else I should look at? Thanks! -p Pat Hirayama Pronouns: he/him/his Systems Engineer IT | Systems Engineering - Infrastructure Fred Hutch Cancer Center O 206.667.4856 phirayam(a)fredhutch.org<mailto:phirayam@fredhutch.org>

Mailman 3 MFA with django-allauth[mfa]
by Liam Reilly Oct. 29, 2025

Oct. 29, 2025

Has anyone successfully got MFA working in Mailman 3 with django-allauth[mfa]? I'm struggling to get it working with the limited documentation I could find. (https://docs.allauth.org/en/dev/mfa/index.html) If signed in as a user, I can browse to /accounts/2fa/ to activate MFA, but I was hoping to make it a mandatory part of the Sign Up process. Is there something that needs to be done with the URLs somewhere? This list site is an example of how I'd like it to work: https://mailing-lists.imperial.ac.uk/ Here is what I added to settings.py: #---------------------------------------- INSTALLED_APPS= ['hyperkitty', 'postorius', 'django_mailman3', 'django.contrib.admin', 'django.contrib.auth', 'django.contrib.contenttypes', 'django.contrib.sessions', 'django.contrib.sites', 'django.contrib.messages', 'django.contrib.staticfiles', 'django.contrib.humanize', 'rest_framework', 'django_gravatar', 'compressor', 'haystack', 'django_extensions', 'django_q', 'allauth', 'allauth.account', 'allauth.mfa', 'allauth.socialaccount'] # Specifies the adapter class to use, allowing you to alter certain default behaviour. MFA_ADAPTER = "allauth.mfa.adapter.DefaultMFAAdapter" # Used to override forms. Defaults to: MFA_FORMS = { 'authenticate': 'allauth.mfa.forms.AuthenticateForm', 'reauthenticate': 'allauth.mfa.forms.AuthenticateForm', 'activate_totp': 'allauth.mfa.forms.ActivateTOTPForm', 'deactivate_totp': 'allauth.mfa.forms.DeactivateTOTPForm', } MFA_RECOVERY_CODE_COUNT = 10 MFA_TOTP_PERIOD = 30 MFA_TOTP_DIGITS = 6 #---------------------------------------- Thanks.

Configuring Web Front End
by Dennis Putnam Oct. 21, 2025

Oct. 21, 2025

The next layer of the onion is configuring the web front end. Specifically setting up Django. The documentation seems to make a lot of assumptions about what I know about Django (which is nothing). I cannot find anything about what 'settings.py' should look like for mailman3. It is not even clear where it should go (/opt/mailman/var/etc?). The Django setup documentation is of no help for mailman3. Am I missing something in the wiki?

Unprocessed Bounce Mails from user with e-mailadresse with a "-" in it
by Wikinaut Oct. 14, 2025

Oct. 14, 2025

The recipient address abc-given.name(a)online.de (member of list mylist(a)myserver.de) has currently an out of office responder and mails are returning to my mailman3 system as unrecognized bounce messages. I suspect the "-" in his address to be in conflict with the bounce address hyphen: <mylist-bounces+abc-given.name=online.de(a)myserver.de> Can any of you experts try on their systems, whether this a bug of mailman3 due to the "-" in the address?

default processing
by Sam Darwin Oct. 13, 2025

Oct. 13, 2025

Notice the repeated use of the word "default" (which is a great word, by the way). This creates confusion: Default action to take when this member posts to the list. List default -- follow the list's default member action. Default Processing -- run additional checks and accept the message. Due to backwards compatibility it may be difficult to change. But if it could be modified, how about: Action to take when this member posts to the list. List default -- follow the list's default member action. Standard Processing -- run additional checks and accept the message. In other words, in the context of message acceptance, the word "default" should have a certain selected meaning. Then make extra effort to choose other words for other actions, as proposed here, "Standard Processing", or something similar.

Can't subscribe on new site/domain

REST API: create list: list styles
by Peter Knowles Oct. 7, 2025

Oct. 7, 2025

I've read that List Styles are essentially python plugins and/or hard coded into the source... Ugh. I was wondering, instead of hacking together some Python code, as I'm a humble PHP dev... Is it possible... 1. To pass all "style" values to the REST API upon creating a list "manually"? Essentially setting all the options on creation. 2. Where can I find a full list of options that can be set on a list, and their accepted values (boolean, string, etc) Thanks in advance!

Oct. 6, 2025

Hi. I am temporarily using Sendgrid now on my Mailman instance. Initial observations have been positive. A list with 100 users is racking up email delivers though, I am on the basic paid account which gives me 50k emails per month. I was hoping to use a cheaper provider and pay overage costs per email on the assumption that I'm seeing a spike in traffic today because people have started getting the messages again. Sendgrid is maintaining the Message-Id header which is good for archiving. It is re-writing the Return-Path header though which means that bounce handling in Mailman won't work, but I think all the services do this in some way so I am happy to live with that for the moment. Hope this helps. Andrew.

Mailman3 equivalent of list_owners binary
by l.reilly＠ucl.ac.uk Oct. 3, 2025

Oct. 3, 2025

Hi, In our Mailman 2 environment we have a script that uses the binaries 'mailman/bin/list_owners' and 'mailman/bin/sync_members' to keep a list of owners up to date. This is handy for sending out service notifications to all list owners. Unfortunately, there doesn't seem to be an exact equivalent in Mailman 3 for list_owners. I've tried using the command 'mailman members --role administrator LISTSPEC' whilst looping through each list from the output of 'mailman lists'. It almost does the job, but in cases where an owner has a display name set the sync fails as it cannot parse these lines. e.g. Cannot parse as valid email address (skipping): Smith, John <john.smith(a)example.com> I can probably try to clean the output of "mailman members" before doing 'mailman syncmembers'. I just wondered if anybody is doing something similar and has a better approach I'm missing? Thanks

deleting a list of spammers from non-member list
by Philip Bondi Oct. 2, 2025

Oct. 2, 2025

Hello to all: I've studied the following: https://docs.mailman3.org/projects/mailman/en/latest/src/mailman/commands/d… ```bash mailman shell -l mmlist.domain.ca << EOF | tr , '\012' > nonmember.txt list(m.nonmembers.members) EOF ``` I was able to produce a clean list of 50 non-member email addresses that are spammers. How would I take this list of non-members and delete them? I was unable to use mailman delmembers

Login confusion
by Markus Grandpré Oct. 2, 2025

Oct. 2, 2025

Dear list, We've encountered an issue with Postorius after migrating from Mailman 2.1. It appears that Postorius is treating email addresses with differing capitalization as distinct user accounts. For example, <markus.grandpre(a)uni-konstanz.de> and <Markus.Grandpre(a)uni-konstanz.de> are being recognized as separate identities. This is causing significant confusion. Users registered with one capitalization pattern are not seeing the list subscriptions and settings that were previously associated with their account (imported from Mailman v2.1) which used a different capitalization. Is there a known configuration option or method within Postorius (or Mailman 3 itself) to normalize or unify account identification, effectively treating email addresses as case-insensitive for account matching? We need a solution that ensures users see their correct list memberships regardless of the capitalization they use when logging in or that was used during the original Mailman 2.1 import. Thank you in advance Markus -- Markus Ludwig Grandpré Universität Konstanz Kommunikations-, Informations-, Medienzentrum (KIM) Abteilung IT-Dienste Forschung und Lehre, B803, Tel: ++49 7531 88 4342

Auto discard after max_days_to_hold not working.
by Hitashi mancho Sept. 30, 2025

Sept. 30, 2025

Dear all, I have migrated around 300 mailing lists from Mailman 2 to Mailman 3. In most of the mailing lists we have configured "max_days_to_hold" to 2. It was working fine in Mailman 2. However, it is not working in Mailman 3. Mailman version: GNU Mailman 3.3.10 (Tom Sawyer) Python 3.11.9 Rocky Linux 9.5 Crontab: @daily /opt/mailman/venv/bin/mailman digests --periodic 00 08 * * * /opt/mailman/venv/bin/mailman notify * * * * * /opt/mailman/venv/bin/mailman-web runjobs minutely 0,15,30,45 * * * * /opt/mailman/venv/bin/mailman-web runjobs quarter_hourly @hourly /opt/mailman/venv/bin/mailman-web runjobs hourly @daily /opt/mailman/venv/bin/mailman-web runjobs daily @weekly /opt/mailman/venv/bin/mailman-web runjobs weekly @monthly /opt/mailman/venv/bin/mailman-web runjobs monthly @yearly /opt/mailman/venv/bin/mailman-web runjobs yearly Please guide me in this regard.

Managing mailman3 via curl (using bash-scripts or perl-scripts)
by Christian Schneider Sept. 30, 2025

Sept. 30, 2025

Hello Mark, hello Stephen, sorry for bothering again...but the amount of documentation is overwhelming... Some info about my setup: I run mailman3 in an virtual environment with postgresql-Server (all in recent versions) - operating system Ubuntu 24.04-LTS. My aim is to provide one high-level script for the daily task of list creation. - list creation via command-line script with two/three parameters like: ./create-list --listname myfirst.list(a)lists.example.org --admin-email admin-user(a)example.org [--admin-name "Peter Rabbit"] The create-list script itself should be a bash- or perl-script (I am not very familiar with python - SORRY ;-) ) I would like the scripts to trigger some curl-calls on the mailman server (from outside the mailman shell and even from outside the virtual environment) Reading the RestAPI documentation here: https://docs.mailman3.org/projects/mailman/en/latest/src/mailman/rest/docs/… several questions arise: 1) Can I succeed with this plan? (Are curl-calls sufficient? Is it possible from outside the virtual environment?) 2) Is this a viable curl-call to create a user?: curl -X POST -u 'admin-user:<password>' -H "Content-Type: application/json" -d '{ "email": "peter.rabbit(a)example.org", "display_name": "Peter Rabbit", "password": "secret" }' http://localhost:8001/3.1/users 3) and in a second step can I assign this user to a list as owner with a curl-call like this?: curl -X POST -u 'admin-user:<password>' -H "Content-Type: application/json" -d '{ "list_id": "newsletter.lists.example.org", "subscriber": "peter.rabbit(a)example.org", "role": "owner" }' http://localhost:8001/3.1/members 4) What about the commits that are used while operating in mailman shell? (Do I have to trigger commits while operating via curl-calls? And how can I trigger commits via curl?) 5) In the unlikely event that I change from the dark side to the good side i.e. "python programming" ;-) is there a "to-the-point" reference for IListManager, IUserManager etc. giving available functions (with parameters) in a kind of list way? (the example kind of documentation referenced above is good, but where can I find a list of all functions?) 6) I think the starting point for managing lists with python is here: https://docs.mailman3.org/projects/mailman/en/latest/src/mailman/commands/d… right? 7) Going the python way will require to enter the virtual environment, right? (otherwise the libraries, environment variables etc. are not available...I think) Thank you for some guidance here... :-) Kind regards Chris

How well does DMARC mitigation work nowadays?
by tom＠tomsmyth.ca Sept. 28, 2025

Sept. 28, 2025

Specifically the kind where all list emails come from the the same address, with the sender in Reply-To? It seems like this /should/ be the way it works. Isn't that what Reply-To is for? Do some email clients still mess it up? If they do, wouldn't it make sense to just send them a bounce notice and tell them to clean up their act? Context: considering moving to a paid email service like Mailgun or Twilio and having random unverified email addresses in the From: header seems to be a nonstarter for them, which makes sense.

CSV Export in Postorius only export email addresses but no names
by Flo Sept. 28, 2025

Sept. 28, 2025

Hi, I want to export the addresses of a mailing list in Postorius. At the List Members section I found 'CSV Export'. However it only exports the email addresses without the names. Is there a trick to make this happen? Thank you. Flo
