Use the "header" filter instead (this is in my .tmda/filters/incoming 
file):

headers '^X-BeenThere: [email protected]' ok

If you change the 'ok' to 'drop' it would blacklist all emails from this 
list :)

The basic idea is if you can find something consistent in the headers, you 
can do whatever you like with it.
