[qmailadmin] Spam filtering and forwarding - simpler question

[Soutien technique / Technical Support]

Reading the thread on spam filtering and forwarding, I've come up with a 
simpler question that would help in my situation.  Currently, when both 
the spam filter and a forwarding address are specified, the spam filter 
comes after the forward in the .qmail file.  My spam filter uses an 
exitcode to specify whether the forward should take place.  The spam 
filter does not do the delivery itself.  Because of this, I would like 
to have it add the local delivery line when the spam filter is 
selected.  The spam filter would also have to appear as the first 
element in the .qmail file.  Could anyone help me by pointing out an 
approximate location on the source to start looking into making these 
changes for myself, or indicate if these additions have already been 
done by someone else in a similar situation?  Thank you
