A simple solution to the Nabble problem is to filter on the "Message-ID" 
and "References" header.  If either of them contains the string 
"nabble.com", then the message was either posted from Nabble or is a 
reply to a message that was posted from Nabble. Delete both types, and 
Nabble ceases to be a problem.
