Filtering based on body only

Hello,

Read the FAQ's, read the manuals, can't catch a clue anywhere...

The first recipe here works fine, catches anything addressed to 
addreses(_at_)austin(_dot_)rr(_dot_)com
The second, however, isn't catching squat. What I'm trying to do is search 
the body of the message. If the IP's in the list below are in the body, 
then sort to the sw-austin folder.
I've tried various combinations (removing \ characters, parens, etc).

I also tried the following, but it didn't work:

:0: austin-lock
* B ?? (24\.27\.[0-63]\.|24\.93\.[32-63]\.|24\.28\.[64-95]\.)
sw-austin

Any ideas? Everything is falling to default.. :(

Mark
