Hello HelioHost Support Team,
I am experiencing an issue where emails sent from my domain (redactu.com) are being blocked by Gmail with the following error message:
550-5.7.26 Your email has been blocked because the sender is unauthenticated. 550-5.7.26 Gmail requires all senders to authenticate with either SPF or DKIM.
It appears that SPF and DMARC records are not correctly configured for my domain. My domain details are as follows:
Domain Name: redactu.com
Thank you for your support!
