Bandwidth Throttling makes it possible for you to police the consumption of bandwidth used by SecurityGateway, both globally and for individual domains. Using Bandwidth Throttling you can control the rate at which each inbound and outbound SMTP session progresses. Further, you can exclude allowlisted senders, authenticated sessions, and your domain email servers from these restrictions. The Bandwidth Throttling system is calibrated in kilobytes (KB) per second, with default values of 10 for both inbound and outbound SMTP sessions (although both options are disabled by default).
|
Up to 8 KB of data can be sent/received before Bandwidth Throttling takes effect. Therefore this could exceed your limits, depending upon the amounts you have designated below. |
