In one, I see:
dkim=fail reason="signature verification failed" (2048-bit key)
In another, I see the line:
Authentication-Results: luna.archlinux.org; dkim=none

I did try that, by saving the email(s) from Thunderbird. It matches what
I'd expect from the Authentication-Results header.

Correlation does not imply causation. On the other hand, I know very
little about mail protocols so I am just floating suggestions and hoping
someone who knows more than I can find the answer. :)
I did not check every email.

I noticed that. It is slightly frustrating since most things seem to
come from the mailing list rather than the original sender...

"Why is this message in Spam? It's similar to messages that were
detected by our spam filters. Learn more"
So, no. :(
Pastebins of the two emails I have referenced here:

Well, none of them have had the From address changed (although there are
some which do not get changed which were not sent to Spam, so I don't
know if that means anything).
And some users have sent emails that go to Spam as well as emails that
do not go to Spam.
Two users whose email went to spam use gmail.com addresses.
