Non-ASCII Character Sets and Message Filter Action Variables
The system supports the expansion of action variables that contain ISO-2022 style 
character codings (the style of encoding used in header values) and also supports 
international text in the notification. These will be merged together to generate a 
notification that will then be sent as a UTF-8, quoted printable message. 
Matched Content Visibility
When you configure a quarantine action for messages that match Attachment 
Content conditions, Message Body or Attachment conditions, Message body 
conditions, or the Attachment content conditions, you can view the matched 
content in the quarantined message. When you display the message body, the 
matched content is highlighted in yellow. You can also use the $MatchedContent 
action variable to include the matched content in the message subject.
When you view messages in the local quarantine that have triggered message or 
content filter rules, the GUI may display content that did not actually trigger the 
filter action (along with content that triggered the filter action). The GUI display 
should be used as a guideline for locating content matches, but does not 
necessarily reflect an exact list of content matches. This occurs because the GUI 
uses less strict content matching logic than is used in the filters. This issue applies 
only to the highlighting in the message body.  The table that lists the matched 
strings in each part of the message along with the associated filter rule is correct.
