    Also for *nix systems, qmail ( www.qmail.org ) and Clam Anti-virus (
    www.clamav.net ), coupled with qmail-scanner is also a great solution,
    and *all* is open source.. (it can take a lot of time to set up right
    tho, and the learning curve is probably steeper than
    postfix/amavisd-new.. Makes a great content filtering box for protecting
    Exchange servers as well...
