Safelist internal domains for sending inbound emails

The default Spoofing rule in GravityZone Security for Email automatically quarantines any inbound emails sent between internal domains (e.g., [email protected] to [email protected]) as spam.

There are legitimate cases where third-party external servers send inbound emails that appear to originate from your internal domain. Determine whether such scenarios apply to your organization, and if they do, add the sending server IP addresses to the GravityZone Security for Email global safelist.
