Chapter 6      Using Message Filters to Enforce Email Policies
When encountered in a message filter, the 
html-convert()
 filter action only tags 
the message to be processed but does not immediately make a change to the 
message structure. The changes to the message only take effect after all 
processing is complete. This allows the other filter actions to process the original 
message body prior to modification.
Bounce Profile Action
The 
bounce-profile
 action assigns a previously-configured bounce profile to the 
message. (See 
undeliverable, the bounce options configured via the bounce profile are used. 
Using this feature overrides the bounce profile assigned to the message from the 
listener’s configuration (if one is assigned).
The following filter example assigns the bounce profile “fastbounce” to all email 
sent with the header 
X-Bounce-Profile: fastbounce
:
fastbounce:
   if (header ('X-Bounce-Profile') == 'fastbounce') {
        bounce-profile ('fastbounce');
   }
Bypass Anti-Spam System Action
The 
skip-spamcheck
 action instructs the system to allow the message to bypass 
any content-based anti-spam filtering configured on the system. This action does 
nothing to the message if no content-based anti-spam filtering is configured, or if 
the message was never flagged to be scanned for spam in the first place.
The following example allows messages that have a high SenderBase Reputation 
Score to bypass the content-based anti-spam filtering feature:
whitelist_on_reputation:
   if (reputation > 7.5) 
   {
