Then open the ``.env`` file to setup the mail server. Modify the ``ROOT`` setting
Important configuration variables
to match your setup directory if different from ``/mailu``.
---------------------------------
Modify the ``VERSION`` configuration in the ``.env`` file to reflect the version you picked.
Open the ``.env`` file and review the following variable settings:
Set the common configuration values
- Change ``ROOT`` if you have your setup directory in a different location then ``/mailu``.
-----------------------------------
- Check ``VERSION`` to reflect the version you picked. (``master`` or ``1.5``).
Open the ``.env`` file and set configuration settings after reading the configuration

documentation. Some settings are specific to the Docker Compose setup.
Modify ``BIND_ADDRESS4`` to match the public IP address assigned to your server.
TLS certificates
This address should be configured on one of the network interfaces of the server.
````````````````
If the address is not configured directly (NAT) on any of the network interfaces or if
you would simply like the server to listen on all interfaces, use ``0.0.0.0``.
Modify ``BIND_ADDRESS6`` to match the public IPv6 address assigned to your server.
The behavior is identical to ``BIND_ADDRESS4``.
Set the ``TLS_FLAVOR`` to one of the following
Set the ``TLS_FLAVOR`` to one of the following
values:

- ``cert`` is the default and requires certificates to be setup manually;

When using *Letsencrypt!* you have to make sure that the DNS ``A`` and ``AAAA`` records for the
all hostnames mentioned in the ``HOSTNAMES`` variable match with the ip adresses of you server.
Or else certificate generation will fail! See also: :ref:`dns_setup`.
Bind address
````````````
Modify ``BIND_ADDRESS4`` and ``BIND_ADDRESS6`` to match the public IP addresses assigned to your server. For IPv6 you will need the ``<global>`` scope address.
You can find those addresses by running the following:
..code-block:: bash
[root@mailu ~]$ ifconfig eth0
eth0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
If the address is not configured directly (NAT) on any of the network interfaces or if
you would simply like the server to listen on all interfaces, use ``0.0.0.0`` and ``::``. Note that running is this mode is not supported and can lead to `issues`_.
