there are some online spam archives that you can download and feed, and
while it may take you a little time to write a script to push the archives
at your spam filter (and if you push the archive at the filter multiple
times, it may learn faster), you will have written a portable tool that
you can use again and again, and will have tailored your email filters 
the way you want, rather than the way someone else wanted.  teaching your
users to foward spam to spam at yourdomain.com will also speed that process

i am no longer associated with them, but usa.net has some good stuff too,
and while i would, for financial reasons, prefer to roll my own, 
outsourcing can be an effective way to manage your email, but it comes
down to a cost/benefit analysis.

brightmail is quite good

i agree - like i said above, you can tailor it to suit your needs.  one
size does not necessarily fit all
