Cisco ESA--- Message Filter

I am sharing some commonly used message filter in Cisco ESA (Ironport)

Filter to Drop any message from a particular sender:

FilterName:
if (mail-from == 'xyz@abc.com')
{
drop();
}. 


Filter to notify your administrator that workqueue count in Cisco ESA reached 100:

Workqueue_Notification:
if workqueue-count == 100
{notify ("xyz@abc.com, abcd@abc.com", "Workqueue reached 100");
 } .
