top-down fashion.

Given the following Incoming Mail Email Security Policy table shown in 

, incoming messages will match different policies. 

A message from sender 

bill@lawfirm.com

 sent to recipient 

jim@example.com

 

will match policy #2, because the user description that matches the sender 
(

@lawfirm.com

) appears sooner in the table than the user description that matches 

the recipient (

jim@

). 

Sender 

joe@yahoo.com

 sends an incoming message with three recipients: 

john@example.com

, 

jane@newdomain.com

, and 

bill@example.com

. The message 

for recipient 

jane@newdomain.com

 will receive the anti-spam, anti-virus, virus 

outbreak filters, and content filters defined in policy #3, while the message for 
recipient 

john@example.com

 will receive the settings defined in policy #5.

bill@example.com
