i've been investigating the dkim/dmarc settings for our mailman3
instance and have finally figured out that in order to stop breaking the
original dkim signatures, we'll need to stop adding the list footer to
mails and remove the [listname] prefix from the subject.
i'm trying that out here on the meta list and we'll see how that works
anyone have any strong feelings one way or the other?
it should be pretty trivial to add mailing list filtering to your
header List-Id contains <listname>.lists.tildeverse.org
to/cc contains <listname>@lists.tildeverse.org
holler if you have any thoughts
