$Date

 message filter action variable.

The 

header()

 rule checks the message headers for a specific header, which must 

be specified quoted in parentheses (“header name”). This rule may be compared 
to a regular expression, much like the 

subject

and “false” if it is not found. For example, the following example checks to see if 
the header 

X-Sample

sample text

If a match is made, the message is bounced.

FooHeaderFilter:

   if (header('X-Sample') == 'sample text')
