An SPF (Sender Policy Framework) record can improve email security by specifying which IP addresses or domains are authorized to send emails on behalf of a specific domain. This means that any email coming from an unauthorized IP address or domain will be marked as spam or rejected altogether.
SPF records prevent email spoofing, which is when an attacker sends an email that appears to come from someone else’s email address. This is a common tactic used in phishing attacks or to spread malware. By establishing an SPF record, email receivers can verify the authenticity of the sending domain and prevent such attacks from happening.
Overall, SPF records provide an additional layer of protection against email-based threats and can help prevent the spread of spam, phishing, and malware.
