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.
