You need to be really careful about this.  It turns out that getting a *clean* 
spam feed is quite challenging.  You want to make sure it's:

* Verbatim spam (not forwarded, classified, or otherwise messed with)
* 100% spam, in other words you want to be absolutely certain that 
a "legitimate" email didn't slip in, for instance, you want to make sure 
people aren't able to taint it by redirecting real email from their 
mother-in-law
* An accurate representation of the sort of spam you're interested in.  For 
instance, do you care about things that postfix could drop by checking the 
hostname given with HELO?  Are you interested in spam resulting from usenet 
posts, web spiders, or something else?

I have a spam sink--currently turned off--that I can re-enable for you if you 
aren't too picky about the last point.  Better, I think, would be for you to 
seed your own spam sink, but that takes time and maybe you can't wait.
