    I used for my personal mail server e nextcloud.

    Moreover I used it with BgLUG (http://bglug.it/scuole) in our project "Linux in the schools" as Primary Domain Controller on the servers of the IT Lab of the schools.

    Very nice distribution: efficient and easy to use.

    Most users think ClearOS is a great alternative to Zentyal.

    The web interface is more intuitive and easier. and it has more features. Although it has not the option as Exchange server. But that is to me a minor thing. You can add that separately afterwards.
