Using the CLI to Manage Message Filters. The CLI accepts commands for 
working with message filters. For example, you might want to display,

Message Filter Examples. This section contains some real world examples 
of filters with a brief discussion of each. For more information, see

Message filters allow you to create special rules describing how to handle 
messages as they are received. A message filter is comprised of message filter 
rules and message filter actions. 

Message filter rules determine the messages that a filter will act on. Rules may be 
combined using the logical connectors AND, OR, and NOT to create more 
complex tests. Rule expressions may also be grouped using parentheses. 

The purpose of message filters is to perform actions on selected messages. 

The two types of actions are:

Final actions — such as 

deliver

, 

drop

, and 

bounce

 — end the processing of 

a message, and permit no further processing through subsequent filters.

Non-final actions perform an action which permits the message to be 
processed further.
