Chapter 9      Using Message Filters to Enforce Email Policies
  Message Filter Actions
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 
.) If the message is 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
:
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:

Bypass Anti-Virus System Action
The 
skip-viruscheck
 action instructs the system to allow the message to bypass any virus protection 
system configured on the system. This action does nothing to the message if there is no anti-virus system 
configured, or if the message was never flagged to be scanned for viruses in the first place.
