Question about trusted networks

[Kshatriya]

Hey,

I've just read 127.* is now always trusted in the new release of 
SpamAssassin.

However, i have some mailinglists which are being handled with SmartList 
(which runs on top of procmail). So, when a spammail hits this list, it 
gets marked as spam (hopefully), but then it will be processed by 
smartlist and sent to multiple (local) addresses. As a result, it passes 
my local mailserver again, gets scanned again, but now it's in the trusted 
zone (since it's being sent from my own mailserver), so it doesn't get 
marked as spam anymore.

Is there a way to tell SpamAssassin not to "remark" this score (i.e., if 
it's spam, leave it being marked as spam, even if it gets forwarded by a 
local rule?)

Thanks!
