What is SPF (Sender Policy Framework)?

An email authentication method that specifies which mail servers are authorized to send email on behalf of your domain.

Detailed Explanation

Sender Policy Framework (SPF) is a DNS record that helps prevent email spoofing. It contains a list of IP addresses and domains that you approve to send emails using your domain name. When an email arrives, the receiving server checks your SPF record. If the email originates from an unauthorized server, it may be marked as spam or rejected. Properly configuring your SPF record is crucial for high email deliverability.
