If you want to suppress the sending of e-mail messages (SMTP) to clients from SonicWALL 
GAV when a virus is detected in an e-mail or attachment, check the Disable SMTP Responses 
box.
Configuring HTTP Clientless Notification
The HTTP Clientless Notification feature notifies users when GAV detects an incoming threat 
from an HTTP server. To configure this feature, check the Enable HTTP Clientless Notification 
Alerts box and enter a message in the Message to Display when Blocking field, as shown 
below.
With this option disabled, when GAV detects an incoming threat from an HTTP server, GAV 
blocks the threat and the user receives a blank HTTP page. Typically, users will attempt to 
reload the page because they are not aware of the threat. The HTTP Clientless Notification 
feature informs the user that GAV detected a threat from the HTTP server.
Tip
The HTTP Clientless Notification feature is also available for SonicWALL Anti-Spyware.
