Not receiving emails

[Gerald Johnson]

I have set-up Autocrat to send emails when a form is completed. I am not receiving emails to the .yahoo and .gmail addresses. 

I've gotten these messages but have no idea what they mean. I need this issue resolved because I am planning a family reunion and I need the email function to work properly in order for the process to proceed smoothly.

The response from the remote server was:

554 5.7.9 This mail has been blocked because it failed authentication checks against the sending domains DMARC policy. See https://senders.yahooinc.com/smtp-error-codes#dmarc-fail for more information.

The response was:

550 5.7.26 Unauthenticated email from yahoo.com is not accepted due to domain's DMARC policy. Please contact the administrator of yahoo.com domain if this was a legitimate mail.
