Mailu comes with multiple base features, including a specific admin interface, Web email clients (webmails), antispam, antivirus, etc. If you wish to disable some of these features, you are free to do so.
The admin interface is the main Mailu-specific bit, it provides tools to manage your email domains, users, etc.
Emails will be available through IMAP and POP3. You may also enable a Web email client. These do add some complexity but provide an easier way of accessing messages for beginner users.
Email filtering is a really important features. You can still disable it, which will prevent Mailu from doing spam filtering, virus filtering, and from applying white and blacklists that you may configure in the admin interface. You may also disable the antivirus if required (it does use aroung 1GB of ram).
