[Mimedefang] Filter attachments?

[Paul Jahnz]

Several of my users have been receiving what look like variants of the klez 
virus.  The "attachments" are stripped out at our firewall, however the user 
still receives the email from the original "bad" sender with an attachment 
saying "Content type "audio/x-midi" denied by SMTP proxy" or "Content type 
"audio/x-wav" denied by SMTP proxy  Is there a way to filter these messages 
based on the text string above and redirect them to another mailbox?
