I manage a few Exchange boxes, and once you figure out stupid it is fairly painless (forgive me) and it works well (forgive me again)! (I will flog myself for hours after this message for forgiveness). Downside to Exchange is the cost. You will need a 64 bit box with tough hardware, seperate box for the AD (although you can get this to work on the same box, it is not really supported), and lets not forget the fancy CAL's. Cha-ching, Cha-Ching!!! I can't speak for Zimbra as I have never touched it, but the other solutions mentioned already are all excellent. One thing I can speak from experience is the Full blown Courier-MTA. I know the Courier Imap is popular, but the entire Courier system is pretty nice. I have set this up for a few companies in the past, and all were happy. There is a 3rd party outlook plugin available for it as well to support the groupware features. It has a fairly basic web based config admin, webmail, and just about everything you might want. I just thought I'd mention it. Good Luck Brother! Viva la Slackware!!!
