Issue Mail sent from my new email server won't reach Yahoo…?

carlsson

Basic Pleskian
Mail sent from my new email server (Plesk) won't reach any Yahoo accounts. (And also Telia.se – A Swedish ISP and also the old national phone company)

I have tried to send from some different domains, and all reach Gmail, iCloud, Outlook, etc. But not Yahoo mail. After a couple of days I get a delivery failure from Yahoo saying "temporarily deferred due to unexpected volume or user complaints".

• I have checked the server on all blacklists, no hits.

• The failure mail says something interesting: "Authentication-Results: mail.mydomain.se; dmarc=fail (p=QUARANTINE sp=NONE) smtp.from= header.from=mail.mydomain.se" (mydomain is something else)
Ie "dmarc=fail" but according to different test sites I have visited it is setup correct. My knowledge here is not 100% so this may actually mean something.

• The DMARC, DKIM and SPF records are all copied from the Plesk DNS, but inserted at my domain provider who also have the nameservers (of course I have changed the corresponding domains).

• Researching at Yahoo gives nothing.

Any ideas on where to go next?
 
Thanks Peter, I atually used mail-tester a couple of years ago but have forgotten about it.
I definitely see some issues that I can improve. (5.2/10 is not the best score.)
 
It's better now, but Yahoo still complain...
Does anybody know if there's any way to initiate a ticket with Yahoo?
