OT: using bogofilter as gateway to Exchange server

[David N Murray]

Yes.  I have done this successfully, using the following environment.
 - Linux
 - QMail + some patches
 - Bogofilter

You just setup qmail to relay everything to the exchange server.  One
database for the site (I created it in /var/qmail/bogofilter).  Works like
a champ.
