What is SPF and why is it needed?

SPF (Sender Policy Framework) is an email authentication standard designed to prevent sender forgery.

Sender verification

SPF allows verification that an email was sent from an authorized server on behalf of the domain

Protection against spoofing

Prevents sending emails from your domain from unauthorized servers

Improved deliverability

A properly configured SPF increases domain reputation and deliverability of legitimate emails

Flexible policies

Different qualifiers allow flexible configuration of email handling policies

Brand reputation protection

Prevents phishing attacks that can damage your company's reputation

Integration with DMARC

SPF is the foundation for DMARC, which provides more comprehensive protection

How does SPF work?

When a mail server receives an email, it checks the sender's domain SPF record. The SPF record contains a list of IP addresses and mechanisms authorized to send emails on behalf of that domain. If the sender's IP address is not found in the SPF record, the email may be rejected or marked as suspicious depending on the configured policies.
