Mail No Longer Working


Recommended Posts



For months I have had a page on my website that has a contact form. When you submit it, it emails me the message to my yahoo account. As of today however, I get a

Mail delivery failed: returning message to sender


message in my helio email acount. It states this:


If you received this error message, your message was not delivered because Yahoo was unable to verify that it came from a legitimate email sender. Yahoo uses three industry-wide authentication checks to verify that that emails are truly from the domains they claim to come from, and your email failed one or more of them:

  • 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 they have been adopted by all major email providers and many technology companies.



I have no idea what this means, or how to fix it... All I know is NOTHING HAS CHANGED at least on my end... Can anyone help shed some light on this for me (in non texhnical terms, this is my first webste, and I barely know much at all.)


Thanks everyone!


p.s. I dont know how to subscribe to this thread, so could you please email me @ shane@wheresshane.com please!



Thanks guys!!

You will probably find this is an issue with Yahoo accounts as they changed their mail policies regarding email. Information on this is below




Is this happening for all emails that are sent or only for people using a @yahoo.com email address?



I would take a guess and say that the issue would be a from address on the email is taken from the email address entered into the form and then sent via phpmail though the system accounts which causes the security checks to fail and the email is rejected and the above failure notice generated.



As I understood this would only effect emails that had a from address of a Yahoo account but this may not be the case. Which would mean any emails sent to a Yahoo account that fails a check would be rejected however this will need testing to confirm.


@Staff an announcement regarding Yahoos new policies may be helpful if the above is confirmed to be the case.
