Check Point Harmony Email (Avanan) SPF Setup

SPF (Sender Policy Framework) is an email authentication method that helps prevent unauthorized servers from sending emails on behalf of your domain. By specifying which servers are allowed to send for your domain, SPF reduces the risk of spoofing and improves email deliverability.

This guide explains how to set up SPF for Check Point Harmony Email & Collaboration. To ensure proper authentication, you’ll need to add Check Point’s authorized sending servers to your domain’s SPF record.
