Disabling Mass operations
by iMark Jan. 24, 2026

Jan. 24, 2026

Hi All, Can anyone give me a pointer on disabling "Mass operations" (subscribe/removal) in Postorius. Just removing the menu link from the list-owners administration pages would be a good start. On "list-by-list" would be brilliant, but even server-wide would do the job. Cheers, Mark

Internal Server Errors in mailmanweb.log

How do I manually change a member's address? I can't find any way to do that from the mailman-web pages. Do I need to do it within MySQL somewhere? TIA.

Any known cases of "non-members" who aren't explicitly allowed to send to the list with a default rule of "discard" on a list getting through?
by Thomas Ward Jan. 10, 2026

Jan. 10, 2026

We just noticed an oddness in a client's system. Someone sent to a members-only list and it 'got past' moderation controls. The list is set to not allow non-members to send to the list, but somehow it got through the default rule of "discard (no notification)" for a non-member and got to the list. The only oddness I can tell is that there was an emoji (unicode) in the subject line but as I understand how Mailman works, this should NOT have impacted anything, as the sender filter bits happen earlier in message processing. Has *anyone* seen any cases like this before? If this is repeatable or a known issue, it deserves a CVE security bug because this is a **severe** problem.

Unadvertised lists accessible even if not signed in
by Peter Chubb Jan. 5, 2026

Jan. 5, 2026

Hi folks, I'm running Mailman3 3.3.10, with postorius and hyperkitty. I want unadvertised lists to be visible only to the people who are subscribed to them and to site administrators. Right now, anyone who has the name of a list can construct a URL to the signup page, even for unadvertised lists. So, I can go to: https://site.name/postorius/lists/test.site.name/ and get to the test list, even if it is unadvertised. I see people scanning URLs like this in the NGINX logs, looking for lists. How can I prevent anyone not logged in, and not a member of an unadvertised list, from seeing it? Peter C

Getting original message headers
by Peter Chubb Jan. 5, 2026

Jan. 5, 2026

We've been seeing some particularly pernicious spammers recently. They're using gmail accounts; I'd like to report them to Google. To do that I need to find the original message headers. By the time the message gets to the archive, or to the mailing list recipients, all the Received: headers seem to have been deleted, leaving only the ones from my list server outwards. Is there a way to access the original incoming emai, before DMARC mitigation etc., has changed the headers? Peter C

Confirmation Email Not Sent
by dap1＠bellsouth.net Dec. 31, 2025

Dec. 31, 2025

While waiting for the Django problem to be resolved, I am able to make it accept a specific host login to get around the CSRF error. So I am now trying to add a member to my list using the ...join address. I get back a message saying the request is pending. I can also see it on the pending user confirmation page. However, there is nothing showing up on the pending approval page nor is there anything in the mail.log showing an outgoing confirmation email or email to the list admin about a pending approval. There is nothing in the mailq either, Looking through the logs I see nothing helpful. Where is the confirmation email?

Cannot Run Web Frontend
by dap1＠bellsouth.net Dec. 27, 2025

Dec. 27, 2025

I'm having trouble getting my web frontend working. When I try to access http://localhost/mailman3 I get a 503 error and the following in the apache2 error.log: [Tue Dec 23 13:08:41.584412 2025] [proxy:error] [pid 132768] (111)Connection refused: AH00957: http: attempt to connect to 127.0.0.1:8000 (127.0.0.1:8000) failed [Tue Dec 23 13:08:41.584578 2025] [proxy_http:error] [pid 132768] [client 2600:1700:5cac:4600:fc36:9a27:6e66:44b:49658] AH01114: HTTP: failed to make connection to backend: 127.0.0.1 This is the relevant part of apache2's 000-default.conf: <IfModule mod_proxy.c> ProxyPreserveHost On ProxyPass "/mailman3" "http://127.0.0.1:8000/mailman3" ProxyPass "/archives" "http://127.0.0.1:8000/archives" ProxyPass "/accounts" "http://127.0.0.1:8000/accounts" ProxyPass "/admin" "http://127.0.0.1:8000/admin" ProxyPass "/user-profile" "http://127.0.0.1:8000/user-profile" </IfModule> What is a bit confusing but probably unrelated is this is in the virtual section for port 80 rather than port 443.

Upgrading dockerized Mailman3 from 0.4 to 0.5.1
by jesper.holck＠ibsgaarden.dk Dec. 27, 2025

Dec. 27, 2025

I am a happy user running Mailman 3, dockerized, in combination with Mailcow. After a few initial problems, everything is running smoothly. Now I'm considering upgrading from 0.4 to 0.5.1, but I'm not sure about the right procedure. Is it something like this? * Stop Containers: # docker compose down * Change the two occurrences of "0.4" to "0.5.1" in my docker-compose.yaml file * Pull New Images: # docker compose pull * Restart: # docker compose up -d Will there be any need for database migrations? Thanks for all the work many of you has put into this.

Internal server error instead of web interface
by Christian H. Kuhn Dec. 18, 2025

Dec. 18, 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

migrating mm21 to mm3 with different domain
by Thomas Krichel Dec. 17, 2025

Dec. 17, 2025

Hi gang, I want to migrate mm21 to mm3, by changing the domain of the list, thus LIST@OLD_dom to LIST@NEW_DOM. I run on debian, with the debian testing version of mm3 installed. Is there an obvious way to do that? Right now I think 0. create new list 1. read mm21 pickle to change the domains in it, write to temporary pickle 2. run mailman import with that pickle 3. read the archive mailbox and change the domain in all the headers 4. change the domainname in bodies and attachments (?) 5. run hyperkitty import This may be the project of a madman... any advice? -- Written by Thomas Krichel http://openlib.org/home/krichel on his 22110th day.

One-click unsubscribe?
by Jered Floyd Dec. 16, 2025

Dec. 16, 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

Postorius permissions granularity
by Liam Reilly Dec. 16, 2025

Dec. 16, 2025

Hi, Is there a way to have more granular permissions in Postorius than either User or Superuser? The user permissions that are configurable under /admin/auth/user/ do not seem to have any effect. We have a helpdesk team that would benefit from being able to access all list pages in the same way as a Superuser, but without the ability to accidentally delete the mail domain for example.

Reject email based on message size.
by Hitashi mancho Dec. 16, 2025

Dec. 16, 2025

Dear all, We have a few mailing lists with a message size limit of 512K. At the same time, these mailing lists are moderated by designated moderators. As configured, posts with a message size greater than 512K are held for moderation. However, even after multiple reminders, some moderators accept these postings. Is there a way to automatically reject all such messages with an appropriate rejection reason? Can we implement a custom rule or a plugin that will help in this case? Regards, Hitachi.

Strange bug I can't reproduce
by MegaBrutal Dec. 15, 2025

Dec. 15, 2025

Hello, I have an application that populates the Reply-To header and sends the e-mail to the list. Under very specific conditions, Mailman may malform this Reply-To header. What I found out is that the second address must match the pattern "Some Name" <a.b0(a)example.com>. The e-mail is properly formatted when it gets into Mailman, but when it is sent out to list members, it gets malformed to Some(a)serverhostname.example.com. Some more info: the first address name is UTF-8 encoded and then "Some Name" wraps into the other line at the middle. I tried to reproduce it like this: Reply-To: =?utf-8?b?QUFBQUFBQUFBQUFBQUFBQUFBQUFBQUFBQUFBQUFBQUFBQUFBQQo=?= < list(a)example.org>, "Some Name" <a.b0(a)example.com> But the problem is not triggered. The problem seems to only present when I send the mail from the application, and so it would be easy to blame the app, but again when I check the queue files, it seems to send the e-mail correctly. It really seems to be a problem with Mailman, I just can't find the exact conditions to trigger it. For privacy reasons I can not share the exact copy of the e-mails on the list, but would it be possible to send it privately so devs could find out where might be the problem? Best regards, MegaBrutal

Hyperkitty attachments

Hi, Hyperkitty provides the possibility to store attachments on the disk by the config parameter HYPERKITTY_ATTACHMENT_FOLDER. Is it possible to export attachments to disk if they are stored in the DB, and have them linked into the archived mail? Is it possible to decide per mailinglist if attachments should be stored in DB or on disk? If not, I would like to request this feature. Thanks, Eric

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

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?

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

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?

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
by Andrew Bernard Nov. 11, 2025

Nov. 11, 2025

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

mailman-web Cleaning Up a Few Issues

Nov. 6, 2025

I seems to be having a problem with some cronjobs not running; I'm getting the following email errors/warnings: Subject: Cron <www-data@dap002> [ -f /usr/bin/django-admin ] && flock -n /var/run/mailman3-web/cron.minutely /usr/share/mailman3-web/manage.py runjobs minutely Body: flock: cannot open lock file /var/run/mailman3-web/cron.minutely: No such file or directory Obviously there is a path specified wrong but I can't find where that is. Subject: Cron <mailman@dap002> /opt/mailman/venv/bin/mailman-web runjobs minutely Body: System check identified some issues: WARNINGS: ?: settings.ACCOUNT_AUTHENTICATION_METHOD is deprecated, use: settings.ACCOUNT_LOGIN_METHODS = {'username', 'email'} ?: settings.ACCOUNT_EMAIL_REQUIRED is deprecated, use: settings.ACCOUNT_SIGNUP_FIELDS = ['email*', 'username*', 'password1*', 'password2*'] Again I could probably fix these if I knew where to look.

"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?

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.

Disable automatic bouncing globally?

Is there a way to disabled the automatic bouncing globally on all lists or do I have to do that on each individual list?

Password reset/confirm email page formatting

Hi, Does anyone else experience this where the pages for password reset/verify email lack formatting. Not sure what the cause might be as all other pages are fine. Please see attached images. 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?

I am about to migrate from mailma2 on CentOS to mailman3 on Ubuntu. Are there any special gotchas of which I need to be aware? TIA.
