    i looked at the sortmonster site and it sounds interesting - anyway, i
    have a strict open source policy (when it comes to our mailserver
    environment) in my company...also i think that tweaking software is
    essential in a *nix ISP environment so im not a big fan of
    out-of-the-box ("you can call the support - but we dont know what all
    this funky binaries do") solutions.
