I'd guess that you can use $entity argument (which is of type 
MIME::Entity, see documentation for details) to access body of the 
message (or just a particular part) in filter, filter_multipart, and 
filter_end functions.  Then, just do substr or regex match on it.  The 
advantage of doing it in filter would be that than you can program it to 
search only text/plain and text/html parts, and skip large binary 
attachments and such.
