Filters and Spam

I'm to do a small anti-spam filter by only accepting email sent to my
new email address (tc@tc.dk - which gets redirected to my tc@login.dknet.dk
address).

So what I want is a filter that deletes (or moves) all email that dosent
contain tc@tc.dk in the to: line. This gives me two/three problems:

How to do a "Not" filter. How to do it if I get another email address -
I will get yet another redirected email address (tc@magna.dk) real soon
now. So what I want is a "(NOT tc@tc.dk) OR (NOT tc@magna.dk) in to: -> Null"
filter.

And how to ensure that my mailinglist filters are done before this filter.

(I get all my spam at the address in the from line and all my personal
email to the address in the reply-to line - good thing that people
writing spam programs are alot stupier than people writing email readers
are :-)

My anti-spam bit:
Please reply to the address in the reply-to: (tc@tc.dk) - anything
sent to the address in the from: line goes to the trashcan.
