--- Comment #12 from Thomas Dukleth <td-koha-bugs at agogme.com> ---
We should change the other BibLibre managed mailing lists to support DMARC by
changing the following two configurations to match the changes for Koha-Devel
before February 2024.  An additional DNS change for Katipo is noted further
below.

In the Mailman web administration interface, change the following two settings.

In the general list personality section change:

from_is_list set to "Munge From"

In the subscription rules section change:

dmarc_moderation_action set to "Munge From".

Alternatively, in etc/mailman/mm_cfg.py the same changes are:

# 1 -> Rewrite the From: header of posts replacing the posters address with
#      that of the list.
DEFAULT_FROM_IS_LIST = 1

# 1 = Munge From
DEFAULT_DMARC_MODERATION_ACTION = 1

After the change, Mailman needs a restart which might be automatic when making
the change via the web interface.

Simon Blake or whoever has access and appropriate knowledge for Katipo also
needs to add a line to the DNS for lists.katipo.co.nz with the leading
underscore as formatted in BIND or in some web interface if one is used for
managing DNS for Katipo.

_dmarc.lists.katipo.co.nz. IN TXT "v=DMARC1; p=none"

While we are working on the potentially large task of setting up, configuring,
and testing Discourse we should minimise people missing mail in their spam box
on Gmail etc. with changes to Gmail, etc. mail delivery policy coming in
February 2024.  Even without migration of archives or list members the task for
Discourse is not trivial, while DMARC compatibility for the mailing lists
sufficient to pass Gmail in my recent testing is trivial with just two or three
settings.
