Traffic shaping options

Administrator Help | Forcepoint Email Security | Version 8.4.x

The Settings > Inbound/Outbound > Traffic Shaping screen lets you determine the rate of traffic delivery for a specified source or destination group based on domain group or user directory settings. For example, these settings allow you to send large volumes of email at a rate that prevents possible blacklisting of the domain.

Change the order of a traffic shaping group by marking its associated check box and using the Move Up and Move Down buttons. Copy an existing traffic shaping group by marking its associated check box and clicking Copy. You can delete a traffic shaping group by marking its associated check box and clicking Delete.

In addition to specifying source and destination user groups, the following message delivery settings may be modified as part of traffic shaping:

Maximum number of concurrent connections

Maximum number of messages per connection within a designated time period

Maximum number of recipients per message

Use of the SMTP session cache, for which the maximum number of messages per session and the session duration are specified

The default traffic shaping group contains no traffic source or destination user groups.

Click Add and use the following steps to establish message traffic shaping controls in your system:

Name your traffic shaping group.

Specify the location in which you want this group to appear in the traffic shaping group list by selecting it in the Order drop-down list.
