Chapter 9      Using Message Filters to Enforce Email Policies
  Message Filter Actions
Drop Action
The 
drop
 action discards a message without any delivery. The message is not returned to the sender, not 
sent to the intended recipient, nor processed further in any way.
The following filter first notifies 
george@whitehouse.gov
 and then discards any message where the 
subject begins with 
SPAM
.
Bounce Action
The 
bounce
 action sends the message back to the sender (Envelope Sender) without further processing.
The following filter returns (bounces) any message from an email address that ends in 
@yahoo\\.com
.
Encrypt Action
The encrypt action uses the configured encryption profile to deliver encrypted messages to email 
recipients. 
   {
        notify('customercare@example.com');
 skip-filters();
   }
spamFilter:
   if(subject == '^SPAM.*')
   {
        notify('george@whitehouse.gov');
        drop();
   }
yahooFilter:
   if(mail-from == '@yahoo\\.com$')
   {
        bounce();
