Ben just fixed this one. Mailman search was case sensitive and my mails 
contained headers like:

    X-Spam-Status: No, score=-2.9 required=7.0 tests=ALL_TRUSTED,BAYES_00
     autolearn=ham autolearn_force=no version=3.4.1

X-Spam-Status: Yes

case insensitively matches 

X-Spam-Status:.*BAYES_00

Ben added a "^" in front of the "Yes" so it needs to stand at the beginning of 
the field content – so this rule shouldn´t match anymore.

Thanks,
