I have set up spf, dmarc, and dkim for my email domain. It *seems* to
work well. I tested it by sending an email to my GMail account. When I
look at the headers of the email, GMail says that it passes all three
tests:
> ARC-Authentication-Results: i=1;
mx.google.com;
> dkim=pass header.i=(a)camerontech.com header.s=default
> header.b=My0caSvG;
> spf=pass (
google.com: best guess record for domain of
> thomas.cameron(a)camerontech.com designates 3.138.45.83 as permitted
> sender) smtp.mailfrom=thomas.cameron(a)camerontech.com;
> dmarc=pass (p=NONE sp=NONE dis=NONE)
header.from=camerontech.com
>
But then, when I do something like send email to this list, I suddenly
get a TON of error messages saying that the email failed spf tests
because it's coming from the server of the mailing list instead of my
email server. Is that normal? It's kind of frustrating. I added the ip
address of the Fedora list server to my spf record, but that seems
really hackish.
What do folks do to set up email with dmarc, spf, and so on?

I have spf, dmarc, etc., set up. I don't recall what happens when I post
to the list, so I'll reply now and see. I'll follow up here if I also
get failure notifications. It doesn't sound familiar.
