Spambox for individual mail accounts

hello, im looking for some assistance on this, i get 3 or 4 pieces of spam in my inbox each day, i have set spam assassin to prepend "Spam: " to the subject of all emails that it deems to be spam, this helps alot when checking my emails because they stand out a bit, anyways, what i would like help with is setting up spamassassin or procmail or postfix (which ever this applies to) to send the spam mail into a junk folder in the user account instead of just laying it into the inbox. any help with this would be greatly appreciated.

OK, problem solved, thanks for the none to little help on this problem.
