I'm going to recommend going with a hosted solution if possible like google or office365. Assuming you have to host it I recommend Zimbra for a good Linux solution that is very much like exchange. Zimbra collaboration suite server can even act like an exchange server to android/ios devices and outlook for the paid for version. It is about as easy to setup/configure and maintain as exchange is. Note: I have maintained a 600 user Zimbra server for almost 10 years now. I have maintained postfix, sendmail, devcot, spam assassin, etc in the past too so I kinda.. kinda know a little bit about this stuff. Rolling your own now days is not worth it in most cases.
