I've been using PHP to send mail to my gmail account from my website for years. This very recently stopped working and the reason given by godaddy representative was "declined due to DMARC policy."
After a little bit of reading, it seems I need to add this to my DNS but before I can, I also have to add SPF & DKIM 48 hours prior to adding DMARC?
I'm really at a loss here. This is levels beyond my experience. A search led me to Google Workspace Admin (but I don't have a Google Workspace Admin account so none of the instructions seem possible)
I'm guessing it's just the lack of ANY dmarc policy on my domain's dns, but I'm finding it very very difficult to find help or instructions that aren't specific to some 3rd party email company's service.
Any help or direction will be very appreciated. Thank you.
