The Disk Space page is used for configuring SecurityGateway to monitor your free disk space. It contains options that can be used to send a warning message to the administrators and/or stop receiving messages if the disk space is low.
Enable disk space checking engine
When this option is enabled, SecurityGateway will monitor the free disk space available on all volumes referenced on the Directories page. This option is enabled by default.
Send warning to global administrators if free disk space falls below [xx] MB
When this option is enabled, a warning message will be sent to the global administrators when the disk space falls below the designated value in megabytes (MB). The default value is 1000 MB, and the option is enabled by default.
Disable the SMTP engine if free disk space falls below [xx] MB
With this option, when the disk space falls below the value designated, SecurityGateway will disable the SMTP engine and therefore no longer accept any messages. The default value is 100 megabytes, and the option is enabled by default.
