Steps to enable Throttling (flow control) in the Email Security

What is throttling (flow control): Throttling is a method of ensuring that a device, will limit ("throttle") the quantity of data it transmits and/or accepts within a specified period of time.

Procedure: 

To enable throttling (flow control) in the Email Security,

Step 1: Please log in to the user interface as an admin user.

Step 2: Navigate to Manage | Security Services | Connection Management | Quality of Service

Step 3: click the checkbox which says “Enable Throttling”.

Throttling can be triggered based on number of connections, messages or recipient commands received from any given IP address in a single day. We can defer future connections from the same IP address for different time intervals (1 hour to 1 year), block future connections from the same IP address or limit future connections from that IP address based on different time durations.

Please click Apply changes after you enable throttling (flow control) in the email security.

NOTE: Please don’t turn on throttling if you are not running email security as a first touch server.
