For optimal performance, it is important that you configure your Secure Email Gateway.
Setting up SEG timeout
When attachments/URLs need to run through a full sandbox scan, emails sent to Intelligent Sandbox could take several minutes for analysis.
Setting the right timeout on your SEG is important, so that it waits until the Intelligent Sandbox scan is complete. A suitable value for timeout depends on the settings for the analyzer profile configured for your Email Connector.
Setting Intelligent Sandbox as a permitted host in your SEG
Depending on your SEG and its configuration, you might be required to include the IP address of the Intelligent Sandbox appliance to your SEG. This allows Intelligent Sandbox to deliver the scanned messages to your SEG.
Setting up SEG functions
Your SEG is expected to perform all anti-spam, anti-virus, or other blocking and filtering functions. Intelligent Sandbox does not perform any of these SEG functions. Messages to Intelligent Sandbox must be redirected only when the SEG:
is not sure about the content of the email
requires an Intelligent Sandbox verdict to enforce a policy accordingly.
