Checking of emails to Razor server

This may seem like a dumb queston, but I have successfully setup
razor2 spam checking, and so far its captured 6 spam emails, so all
good.

Question is, are the contents of my emails sent to the razor server
for check, or is it just an analasys thats sent? i.e. some of the
emails I received are NOT allowed to leave the netowrk for security
reasons.

Thanks.

Paul.
