Need advice on server/computer for scanning emails as they come in before they are delivered.

[Winchester]

What is the best way to setup a email scanner that just scans for viruses and spam before it hits the exchange server?
Also what specs on a server/computer would be needed to handle email for a non-profit org, about 100 people, so lots of emails.

OS: Doesnt matter Linux or Windows

ex. WWW<->Router<->Scanner<->Switch<->Exchange Server
