This is pretty standard - the main two questions are:
1. What do you want listening on port 25 of the machine
that mail arrives at? Exim/Postfix/Something else.
2. How will the mail get form the filter to the exchange
server (via exim/smtp/something else?)
I recommended qpsmtpd to several people, with good success. It
is a perl script which will listen upon port 25, run incoming mail
through plugins (so you can do virus scanning,etc) and then passes
the mail on for delivery through exim4.
In terms of configuration there are two parts - installing qpsmtpd
to make it listen on port 25. THen configuring a local copy of exim4
to listen on a non-standard port and deliver the mail to the exchange
server when it arrives via qpsmtpd.
The latter step can be done easily in a stock debian configuration
by editing the file (creating if necessary) ./etc/exim4/hubbed_hosts.
qpsmtpd is easy to get started with but this guide might help:

I offer such a service commercially (mail-scanning.com) and it
is used by many people with Debian Etch & Lenny. Still I understand
many people like to keep email in-house ;)
