Goal

Create a signal when Google Workspace detects a user setting up mail forwarding to a non-Google Workspace domain.

Monitor Google Workspace logs to detect when email_forwarding_out_of_domain events.

Determine if the email address defined in @event.parameters.email_forwarding_destination_address is legitimate.
If the forwarding destination address is not legitimate, review all activity for {{@usr.email}} and all activity around the following IP: {{@network.client.ip}}.
