Procmail and formail


I am using the following script to filter dangerous email attachments. However when i send an internal email with an exe attached it is not picked up (i.e. not flagged up in the subject of the message when within mutt). I believe the problem lies with formail but am not sure. I use mutt to read my mail. Please help. Thanks in advance
