Change the default value for the General Archive Policy
Dear list,
currently, when I create a new mailing list with MM3 the value for "Archive policy" is always set to "Public archives". I'd like to change the default value for "Archive policy" to "Do not archive this list". How can I do this? In Debian 12 I find in </usr/lib/python3/dist-packages/postorius/forms/list_forms.py>:
mlist_properties = ['archivers']
archive_policy_choices = (
('public', _('Public archives')),
('private', _('Private archives')),
('never', _('Do not archive this list')),
)
archive_rendering_mode_choices = (
('text', _('Plain text')),
('markdown', _('Markdown text')),
)
archive_policy = forms.ChoiceField(
choices=archive_policy_choices,
widget=forms.RadioSelect,
label=_('Archive policy'),
help_text=_('Policy for archiving messages for this list'),
)but have no idea how to change the settings here. Your help is very appreciated.
Best regards, Markus Grandpré

Dear Mr Sapiro, many thanks for your reply. When I create a mailing list without an archive, I’ve noticed that the default value under "Settings > Archiving > Archive policy" is always set to "Public archives". I was wondering if it's possible to change the default to "Do not archive this list" instead. Additionally, in an earlier email, you mentioned that a more convenient way to set default values would be introduced in an upcoming version. Could you please let me know the current status of that development? Many thanks in advance. Best regards, Markus Am 6/23/25 um 19:53 schrieb Mark Sapiro:

I don't understand. What do you mean by create a mailing list without an archive?
Do you mean that your mailman.cfg does not enable any archivers or something else?

You cannot do that in Postorius. All of the "style" options provide for an archive. "Ordinary discussion" and "announce" have public archives, and the last option is "discussion with private archives". How are you doing this?
"Settings > Archiving > Archive policy" is always set to "Public archives". I was wondering if it's possible to change the default to "Do not archive this list" instead.
The choices for setting are defined at line 386 (or so) of postorius/forms/list_forms.py:
archive_policy_choices = (
('public', _('Public archives')),
('private', _('Private archives')),
('never', _('Do not archive this list')),
)This is implemented as a line of radio buttons. There is no default for a *new* list, it's implied by the style choice. For an existing list you are shown the current setting -- there's no default to change to, you have to click on a button. If by "default" you mean "first in the list", you can patch the form in Postorius, but we're not going to change the order, since our primary audience is public discussion lists.
In theory we could provide a mechanism to configure the order, but I think that's very unlikely to happen -- Mailman isn't and doesn't want to be Emacs.

Dear Mr Hochstein,
Thank you very much for providing the link. I'm afraid the same misunderstanding as with Marc Sapiro has occurred here. I'm aware that there are three different styles to choose from when creating a mailing list. However, the setting "Settings > Archiving > Archive policy" can be configured independently of the list creation process.
Still, it would be beneficial if the default value after creating a list without an archive were not "Public archive", but rather "Do not archive this list". This would help prevent list administrators from being tempted to immediately enable a public archive when setting up an archive later—especially in cases where the list is intended to be private.
Kind regards, Markus Grandpré
