Subject: Blocking messages without the list address in To: or CC:

Much/most spam is sent out in bulk such that the recipient addresses aren't 
put in the To: header - as if they'd been BCC'd on the mail.

Is there a way to write a taboo_header rule so that it will match messages 
which do _not_ have a To: mylist@mydomain.com or CC: mylist@mydomain.com 
header?

Alternately, is there an good way to write something to do the job?  Maybe 
another thing like resend, for this specific task?

(I know the usual solution is to restrict_post, but this technique would be 
a good 90% solution for those of us who want/need to keep our lists open).
