Ensure automatic forwarding options are disabled (Manual)

Description

You should disable automatic forwarding to prevent users from auto-forwarding mail.

Rationale

In the event that an attacker gains control of an end-user account they could create rules to ex-filtrate data from your environment.

Impact

Care should be taken before implementation to ensure there is no business need for case-by-case auto-forwarding. Disabling auto-forwarding to remote domains will affect all users and in an organization.
