Email marketer from StackExchange responds that a strict DMARC policy on the sender's (Yahoo) domain, combined with incorrect SPF or DKIM settings on the recipient's side (GSuite/Zendesk), can cause email delivery failures. They recommend verifying SPF and DKIM records and ensuring they align with Yahoo's requirements.
