spamc/qmail-queue problem

[josh abbott <ja...@load.com>]

right now my setup is spamc | qmail-queue. however, i'd like to be able 
to check the header that spamc includes in its stdout that tells if the 
mail is spam or not. if it is spam, i'd like to send it to some 
quarantine directory, if it isn't i'd like to send it to qmail-queue. 
my problem is that if i check the stdout for a header, i can't use that 
as the stdin for qmail-queue, unless i save it as a file first. any 
suggestions?
