How to view blocked mail's header?
Groups.io says Yahoo has blocked mails from other groups.io users:
"mx-eu.mail.am0.yahoodns.net: 554 Message not allowed - [PH01] Email not accepted for policy reasons. Please visit https://senders.yahooinc.com/error-codes "
Yahoo continues:
"To check if your email was sent using DMARC, you'll need to view the raw message."
How I can see the blocked message's header when Yahoo has blocked it? Cannot I say all mail from groups.io is ok?
Another thing I live outside US. but use English Windows and English Firefox. While visiting page:

Yahoo threw on my screen something that was not english, it was on the lanuage the natives speak here. There was no option to select language
