What is Sender Policy Framework?
SPF (Sender Policy Framework) is an email validation system that helps prevent email spoofing.
By using DNS records, it allows the email system to check if the incoming mail comes from a domain that's authorized by that domain's administrators.
Exim is a widely used mail transfer agent (MTA) that manages the sending and receiving of emails on a server.
