What you describe below is not the same thing as I was suggesting. I
was suggesting having a static, never-changing "seed" of a nominal
sample of typical spam messages and (perhaps faked) legitimate messages
that every user could start with to jumpstart their analysis. Everyone
starts on the same footing, because they need somewhere to go.
Thereafter, they build up their own private good and bad corpora
independently of the initial seed and all other users.

Then this raises issue of who decides what goes into the spam corpus.
If that's decided by third parties, then someone has the potential of
reading private mail. And it still comes down to a matter of
individualty: _Both_ the corpora need to vary with my own personal
taste, or otherwise it's not going to accurately reflect what _I_ as an
individual want to see. Someone who gets a lot of (legitimate)
commercial email may get a lot of false positives and have difficulty
doing anything about it, since he can't control the spam corpus, only
his (private) non-spam corpus.

The client/server model also brings up another obvious issue: Ask you
what your roommates think about the potentiality for you to be able to
read all of their email.
