----
-
-This guide is an addition to the [FreeBSD email server series][tutorial-email].
-It is not required for your email server to operate properly, but it is often
-considered a very important feature for those who want to switch from a third
-party email provider to their own solution. It does build upon the completed
-series, so be sure to work through that before starting on this.
-
-## Install required packages
-{% highlight sh %}
-pkg install py27-radicale
-{% endhighlight %}
-
-## Configure Radicale
-### /usr/local/etc/radicale/config
-Open up the `/usr/local/etc/radicale/config` file, and update each `[block]`.
-
-#### [server]
-The server is binding to `localhost` only. This way it is not accessible on
-`:5232` from outside the server. Outside access will be provided through an
-nginx reverse proxy instead.
-
-{% highlight ini %}
-hosts = 127.1:5232
-daemon = True
-
-dns_lookup = True
-
-base_prefix = /
-can_skip_base_prefix = False
-
-realm = Radicale - Password required
-{% endhighlight %}
-
-#### [encoding]
-{% highlight ini %}
-request = utf-8
-stock = utf-8
-{% endhighlight %}
-
-#### [auth]
-{% highlight ini %}
-type = IMAP
-
-imap_hostname = localhost
-imap_port = 143
-imap_ssl = False
-{% endhighlight %}
-
-#### [storage]
-{% highlight ini %}
-type = filesystem
-filesystem_folder = /usr/local/share/radicale
-{% endhighlight %}
-
-#### [logging]
-{% highlight ini %}
-config = /usr/local/etc/radicale/logging
-{% endhighlight %}
-
-### /usr/local/etc/radicale/logging
-This file is fine on the defaults in FreeBSD 11. This saves you from
-configuring a little bit.
-
-## Configure Dovecot
-### Enable imap
-This option was disabled in the [IMAP server tutorial][tutorial-email],
-however, if we want to auth using the same credentials as the mailserver, this
-option is needed again. Bind it to `localhost`, so it can only be used
-internally. In `/usr/local/etc/dovecont/conf.d/10-master.conf`, enable the
-`imap` port again:
-
-```
-...
-service imap-login {
-    inet_listener imap {
-        address = 127.1
-        port = 143
-    }
-    ...
-}
-...
-```
-
-## Configure nginx
-To make using the service easier, you can setup [nginx][nginx] to act as a
-reverse proxy. If you followed the [webserver tutorial][tutorial-webserver],
-you already have the basics for this set up. I do recommend you check this out,
-as I will only explain how to configure a virtual host to deal with the reverse
-proxy here.
-
-### Setup a reverse proxy
-Assuming you have taken the crash-course in setting up the nginx webserver, you
-can attain a reverse proxy using the following config block. Note that this block
-only does HTTPS, as I use HTTP only to redirect to HTTPS.
-
-{% highlight nginx %}
-# static HTTPS
-server {
-    # listeners
-    listen       443 ssl;
-    server_name  radicale.domain.tld;
-
-    # enable HSTS
-    add_header  Strict-Transport-Security "max-age=31536000; includeSubdomains; preload";
-
-    # keys
-    ssl_certificate      /usr/local/etc/letsencrypt/live/domain.tld/fullchain.pem;
-    ssl_certificate_key  /usr/local/etc/letsencrypt/live/domain.tld/privkey.pem;
-
-    # / handler
-    location / {
-        proxy_set_header Host $host;
-        proxy_set_header X-Real-IP $remote_addr;
-        proxy_pass http://127.1:5232;
-    }
-}
-{% endhighlight %}
-
-## Enable the service at startup
-{% highlight sh %}
-echo 'radicale_enable="YES"' >> /etc/rc.conf.local
-{% endhighlight %}
-
-## Start the server
-{% highlight sh %}
-service radicale start
-{% endhighlight %}
