I do not recommend the use of procmail for this purpose because your 
mail delivery will get very CPU and memory expensive and so, in most 
cases, very slow.
As explained by Craig it's up to the MTA to scan for spam.
Personally, i prefer Postfix-Amavis-Cyrus: Postfix gives the received 
mail to Amavis which starts (in my case) at first a virus-scanner and 
then spamassassin. If a virus was found the mail delivery is stopped. If 
it is spam a Header-Tag will be added (X-Spam-Level). Amavis gives the 
mail back to Posfix that will deliver local mail to Cyrus. Sieve is now 
started and checks whether the mail has a Header-Tag named X-Spam-Level 
and if true the message will be put in the INBOX.Junk folder.
