{% call macros.panel("info", "Step 4 - expose Mailu to the world") %}
|
|
<p>A mail server must be exposed to the world to receive emails, send emails,
|
|
and let users access their mailboxes. Mailu has some flexibility in the way
|
|
you expose it to the world.</p>
|
|
|
|
<p>Among Mailu services, the <em>front</em> server is the one accepting connections,
|
|
be it directly from the outside world, through a reverse proxy or in any
|
|
complex configuration that you might want to setup. It needs to listen on some
|
|
IP addresses in order to expose its public services. You must at least setup
|
|
an IPv4 or an IPv6 address if you wish to access Mailu.</p>
|
|
|
|
<p><span class="label label-warning">Warning</span> You must use specific addresses, please
|
|
avoid generic all-interfaces addresses like <code>0.0.0.0</code> or <code>::</code>.
