I would only agree on the assumption that you are using a single DB for
your entire userbase.  I love getting 'Spam Alerts' from AOL that contain
things like wedding invitations and email that has some word or phrase
that obviously offended the user.

If he is using SpamAssassin on a per-user basis, then that elimitates the
people who think 'Spam' = "Mail I don't want" from tainting other's
opinions.  It also allows people to accept or deny bulk mail based on
their own preferences.  IMHO, it changes the entire concept of
'Spam-detection' into 'types of mail *I* don't like-detection'.  It's up
to you whether or not that's the way you want to go.  

Personally, I have had better luck with per-user training than one common
database.
