hi there I would categorize Exchange 2016 as "groupware" rather than SMTP server per say, because you sent lots of stuff out of Exchange. so to compare Exchange with postfix, exim would not be a proper comparison. For Linux based groupware that i know is completely free is Kolab (https://www.kolab.org/). its fairly easy to setup. Not sure about Zimbra is its Still free as of now. If you are to use postfix, exim or sendmail you would need to setup a webmail for that and use something like SquirrelMail or Dovecot of which that more a bit complex than just setting up Kolab. So in Short if you ware looking for Exchange equivalent in linux try Kolab or Zimbra. don't look at postfix or exim.
