You should also consider that DSPAM, fully trained, can grow very 
large.  I use a single username for a dozen email boxes, and the 
database is 3.5GB.  Though you can trim it by dropping tokens that 
aren't as accurate, or aren't as frequently used, it could still become 
big, especially with a lot of users.
