I am running Discourse and sending verification email, but the emails have my gmail address as sender and they go to spam folder and Google throws a warning that this may be phishing.
Do I need to buy an email through GoDaddy and send through that account? I am sorry, if this is not clear, I am confused about how emails works. Is this related to SPF?
EDIT
I was advised to "...use a domain that you are authorized for, and then create a SPF record with the IP of your forum in that domain." Can you explain what this means?
