Sender Policy Framework (SPF) is a protocol that allows the owner of a domain to specify which mail servers are authorized to send emails on behalf of that domain. This helps to prevent spoofing and phishing attacks by verifying the sender's identity. By configuring SPF for your Oracle Fusion Cloud Procurement application, you can enable the options for the from and reply to email addresses for supplier onboarding and profile management notifications. This will help your suppliers to trust the notifications and avoid them being marked as spam.
