This article explains how to configure SecurityGateway to utilize bandwidth-throttling, which limits the connection speed of incoming and outgoing connections to conserve bandwidth.
From the Dashboard, after logging in:
- Click on Security in the lower-left corner
- Locate the Anti-Abuse section
- Click on Bandwidth Throttling
You may then configure the following options:
-
Limit inbound SMTP connections to xx KiB per second
Incoming sessions will be limited to this many kilobytes per second. By default, this is disabled.
-
Limit outbound SMTP connections to xx KiB per second
Outgoing sessions will be limited to this many kilobytes per second. By default, this is disabled.
-
Exclude messages from domain email server
SecurityGateway will not limit the speed of connections made from any domain email servers that you have configured. By default, this is disabled.
-
Exclude messages from authenticated sessions
If the incoming session authenticates with a username and password on the server, SecurityGateway will not limit its connection speed. By default, this is disabled.
-
Exclude messages from whitelisted senders
If the incoming session is from a host, or IP address, that you have set in SecurityGateway's whitelist, it will not limit the speed of the connection. By default, this is disabled.
