filtering new vbs.freelink worm

I have the following recipe for filtering a new worm that has been found
called vbs.freelink - similar to melissa.  Just seeking input to see if it
looks correct

  * Have fun with these links
  * ^Content-.*: .*\.vbs
  |formail -A "X-Spam-Reject: rc.viruses - vbs.freelink"
} 

anything with a X-Spam-Reject header gets filtered to a special mail
account for later review.

Info on the worm can be found here:
