Description

Hi OpenSUSE Admins,

Recently we at KDE were doing some maintenance on our mail servers and
observed that a significant amount of email had been held by the opendmarc
filter which had originated from OpenSUSE mailing lists.

In particular, this email appears to originate specifically from the SUSE
Bugzilla, as suse.com publishes a DMARC policy of quarantine, and
OpenSUSE's Mailman setup breaks the DKIM signatures attached to the emails.

You may wish to investigate adjusting the configuration of your Mailman
installation to minimize the DMARC compliance issues that it generates.
Specifically this involves not modifying subjects or message bodies
(footers/headers/html stripping/etc).

Please let me know if you need any assistance with this (we did those
adjustments site wide at KDE some years ago - with them being very
successful by and large)

Cheers,
Ben Cooksley
KDE Sysadmin
