You test the policies you have created using the

trace

command with an arbitrary SBRS. See

Debugging

Mail Flow Using Test Messages: Trace, page -446

. The

trace

command is available in the CLI as well

as the GUI.

Note

In the $THROTTLED policy, the maximum recipients per hour from the remote host is set to 20 recipient
per hour, by default. Note that this setting controls the maximum throttling available. You can increase
the number of recipients to receive per hour if this parameter is too aggressive. For more information on
Default Host Access policies, see

Accessing Predefined Mail Flow Policies for Public Listeners,
