Front desk:"Ticket failed DMARC verification, moved to spam queue."

I'm investigating why we're receiving less requests via email from Russia and I was checking the spam queue.

I found some legit emails going there because of failed DMARC verification (example: rambler.ru).

Is it possible to check if emails to frontdesk@tpo are getting rejected or bounced because of DMARC verification or other reason?
