Although I could specify the IP address in my SPF records directly (as you suggested), I do hope that my understanding of DNS records laid out above is not entirely misguided. My current setup does work as expected for eden.one, after all.
As I said at < https://lists.mailman3.org/archives/list/mailman-users@mailman3.org/message/...
I was misreading your DNS and now I am as puzzled as you about the failure.
It gets even more mysterious. I tried sending messages from both lists.eden.one and janeden.net (my other domain) to a gmail account and to another mail provider. Both messages passed the SPF checks on both services (s. the relevant headers quoted below). Now because I send those messages via my SMTP user (smtpuser@eden.one) and use SRS, the SPF check operates (and succeeds) on e.g.
srs0=jdm+=5c=lists.eden.one=testlist-bounces+gmailuser=googlemail.com@eden.one (and not on somethingsomething@lists.eden.one or somethingsomething@janeden.net). Could this be the reason for the failed SPF checks in Yahoo's and Google's DMARC reports?

Might you be willing to use proven tools instead of trying so hard to understand the myth?
I use https://easydmarc.com/tools#spf-tools It allows me to generate, lookup, test SPF, DKIM, DMARC, etc.
