Broadcom policy regarding root-level access and modifications on Symantec Messaging Gateway (SMG) appliances.
Root access to Messaging Gateway (SMG) systems is disallowed by Broadcom Policy. Root access is not supported and also not recommended. Any non-admin level access or modifications, if not performed by Symantec support to resolve technical problems, take the appliance out of full support. If an appliance is not under full support, Messaging Gateway Support can require a customer to restore the appliance to its unmodified state before providing any additional support.
