Hyperkitty Text/Markdown/HTML
by Sam Darwin Sept. 9, 2025

Sept. 9, 2025

How about a feature to include "HTML" in the current Hyperkitty choices of (Text or Markdown) rendering? A sanitizer must be used to prevent malicious attacks. https://github.com/messense/nh3 . lxml is another package that processes html. A sanitizer would be helpful for more aspects. Permit a limited set of markdown so that messages still appear professional. Gitlab/Github don't allow arbitrary fonts or font sizes, right? Mostly remove these tags. A way that code blocks could be presented: determine an established list of known codeblock styles. Configure the sanitizer to permit this range of fonts or styling elements. By allowing them through the filter, a code styling is rendered. (It is permitted/allowed to be rendered.) Even better, when the sanitizer recognizes the fonts, it replaces them with an "official" set of codeblock fonts. Otherwise, if other font tags are entirely removed, if they are missing, the email client or web ui will decide the font selection, and it will appear "standard". In order for both email clients and Hyperkitty to view the same result, the sanitizer should ideally be applied to outgoing emails as well as rendering in the UI. That means this feature would affect more than just Hyperkitty. (i.e. mailman-core). Although, that could be implemented as a separate step, until which time emails would get a full range of HTML, without sanitizing. In this scheme, ensure outgoing emails are multi-part MIME with plain text and html versions. Some of our users are really in favor of more formatting. Others prefer plain text. Those who prefer plain text have various arguments that HTML messages will be rendered badly, and won't be legible. Questions: 1. Would "multi-part MIME with plain text and html versions both" solve the problem for users who prefer plain text? 2. What percentage of email clients that support HTML formatting when sending will also include a plain text rendering of the same content in the outgoing message? 3. Is it usually the responsibility of a receiving mail client to be able to convert HTML to plain text if the user requests it? 4. When mailman-core receives and then sends out a message, can it receive HTML, generate a plain-text version, and then send both? Thoughts?

after last upgrade I've got a CSRF failed verification
by Guillermo Hernandez (Oldno7) Sept. 5, 2025

Sept. 5, 2025

I did upgrade one of my mailman3 server after Abhilasj announcement: "I am pleased to announce several new releases for GNU Mailman project. 1. Mailman Core 3.3.6 1 <https://docs.mailman3.org/projects/mailman/en/latest/src/mailman/docs/NEWS.…> 2. Postorius 1.3.7 2 <https://docs.mailman3.org/projects/postorius/en/latest/news.html#section-2> 3. Hyperkitty 1.3.6 [3] 4. Mailmanclient 3.3.4 [4] 5. Django-mailman3 1.3.8 [5]" I did it via pip and all seems to be working, but when I try to discard or accept any message via postorius it shows a Forbidden 403 error CSRF verification failed. In my settings.py I have commented out these variables: # Other security settings # SECURE_SSL_REDIRECT = True # If you set SECURE_SSL_REDIRECT to True, make sure the SECURE_REDIRECT_EXEMPT # contains at least this line: # SECURE_REDIRECT_EXEMPT = [ # "archives/api/mailman/.*", # Request from Mailman. # ] # SESSION_COOKIE_SECURE = True # SECURE_CONTENT_TYPE_NOSNIFF = True # SECURE_BROWSER_XSS_FILTER = True # CSRF_COOKIE_SECURE = True # CSRF_COOKIE_HTTPONLY = True # X_FRAME_OPTIONS = 'DENY' I've been messing with them whith no results. It's like it lacked some value in some template... Can someone, please, point me in the right direction? Thanks in advance -- ___________________________________________ Mailman's content filtering has removed the following MIME parts from this message.

I'm unsure if i should recover from snapshot or keep it going? Could this be some duplicate users with same mail-address? I have at least spotted one user and delete him. thank you. Stefan

Hi all, i tried to install Mailman3 according to https://docs.mailman3.org/en/latest/install/virtualenv.html#virtualenv-inst….

Question: as Admin, I disabled the self-registration via settings.py. What is the correct method to register a few new users now?
by Wikinaut Sept. 2, 2025

Sept. 2, 2025

Disabled by line ACCOUNT_ADAPTER = 'django_mailman3.views.user_adapter.DisableSignupAdapter' (via https://gitlab.com/mailman/django-mailman3/-/merge_requests/129 ) When I want to register a few new users, I need to comment this line and restart mailmanweb. Question: is there a better method for admins to register a few new persons to Hyperkitty/Postorius so that they can act as owners and moderators of some of the lists?
