If your emails aren't being received by Yahoo Mail accounts, here's information that should help you understand why this is happening.
Why am I seeing this error?
Your message wasn't delivered because Yahoo was unable to verify that it came from a legitimate email sender.
Your email failed one or more of the following industry-wide authentication checks that Yahoo uses to verify emails are truly sent from the domains they claim to originate from. Click an authentication method's link below to learn more.
- DKIM (Domain-Keys Identified Mail)
- SPF (Sender Policy Framework)
- DMARC (Domain-based Message Authentication, Reporting and Conformance)
These standards are designed to eliminate an email user’s exposure to potentially fraudulent and harmful messages and have been adopted by all major email providers and many technology companies.
Yahoo recently changed our DMARC policy This was done to proactively protect our users from increasing email forgery spam.
