[Spambayes] Does spambayes work with Exchange?

[Roger]

We've been using spambayes as Outlook plugin, and the results are great. 
However, when we use webmail, we still see all spam mail. Is it possible 
to use spambayes in front of our Exchange server, so we can filter out 
spam before it gets into the user's mailbox? We use Exchange Server 2000 
on Windows 2000.

Is there a manual on how to configure this?

Thanks!

Roger
