As far as I can see, lists.linux.org.au has no SPF (or TXT for SPF)
records, so spam detection software should see that as a neutral result

On some lists I am responsible for, I have turned on the Mailman
feature that will put a wrapper around any email from a site that
publishes a strict DMARC policy.  It basically turns such emails into a
single mail digest.
