Some of Mailu features are not used by every user and are thus not enabled in a
default configuration.
A Webmail is a Web interface exposing an email client. Mailu webmails are
bound to the internal IMAP and SMTP server for users to access their mailbox through
the Web. By exposing a complex application such as a Webmail, you should be aware of
the security implications caused by such an increase of attack surface. The ``WEBMAIL``
configuration option must be one of the following:
- ``none`` is the default value, no Webmail service will be exposed;
- ``roundcube`` will run the popular Roundcube Webmail;
- ``rainloop`` will run the popular Rainloop Webmail.
The administration interface is not exposed on the public address by default,
you will need to set the ``ADMIN`` variable accordingly:
- ``true`` will expose the admin interface in ``/admin``;
- ``false`` (or any other value) will disable this behaviour.
A Webdav server exposes a Dav interface over HTTP so that clients can store
contacts or calendars using the mail account. This can be enabled using the `WEBDAV`
setting. The configuration option must be one of the following:
- ``none`` is the default value, no webdav service will be exposed;
- ``radicale`` exposes the radicale Webdav service.
An antivirus server helps fighting large scale virus spreading campaigns
that leverage e-mail for initial infection. This can be setup using the ``ANTIVIRUS``
setting. The configuration option must be one of the following:
- ``none`` disables antivirus checks;
- ``clamav`` is the default values, the popular ClamAV antivirus is enabled.
Make sure that you have at least 1GB of memory for ClamAV to load its signature
database.
If you run Mailu behind a reverse proxy you can use ``REAL_IP_HEADER`` and
``REAL_IP_FROM`` to set the values of respective the Nginx directives
``real_ip_header`` and ``set_real_ip_from``. The ``REAL_IP_FROM`` configuration
option is a comma-separated list of IPs (or CIDRs) of which for each a
``set_real_ip_from`` directive is added in the Nginx configuration file.
After downloading the files, open ``mailu.env`` and review the variable settings.
