GoDaddy has discontinued their “free” email service and is moving to Microsoft 365. I am moving my email to Zoho but the fields to change items related to the email server are greyed out.
I don’t know much about the smtp settings other than that’s where you can set them.
Did you also try changing your Site Email and Vendor Email settings?
The link to your settings that you included only leads to your Backlight login page. Can you post screen shots of your settings?
