Safelist internal domains for sending inbound emails

The default Spoofing rule within GravityZone Security for Email ensures that any inbound emails received from internal domains will be quarantined ([email protected] > [email protected]) as spam.

Legitimate scenarios exist where third party external servers send inbound mail from addresses that purport to be from your internal domain. Identify whether such scenarios exist within your organization and if so it, add the sending server IP addresses to the GravityZone Security for Email global safelist.
