    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.

    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.
