To maintain secure communication within school systems, properly managing inbound email gateways is crucial. Enabling an inbound gateway allows email to be filtered by a trusted third-party security tool before entering Gmail, helping prevent spam, phishing, and malware from reaching end users. This setting is especially beneficial if the school is leveraging an external provider for email threat detection.

However, if such a service is no longer in use, retaining the gateway may introduce unnecessary complexity or even risk. School IT administrators should regularly audit the IP addresses associated with the gateway to ensure they are valid and trusted. An outdated or incorrect gateway configuration could disrupt mail flow or inadvertently allow unverified emails through.

By keeping your inbound gateway settings aligned with your actual infrastructure, you can ensure email routing remains secure and reliable.
