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.
