+FIRST APPROACH: Separated config block, getting it as a parameter
+----------------------------------------------------------------
+
+With an extension (more on extensions here) you can keep this easily "separated" into different blocks in the config.yml and then inject that as a parameter gettable from the controller.
+
+Inside your Extension class inside the DependencyInjection directory write this:
+```
+class MyNiceProjectExtension extends Extension
+{
+    public function load( array $configs, ContainerBuilder $container )
+    {
+        // The next 2 lines are pretty common to all Extension templates.
+        $configuration = new Configuration();
+        $processedConfig = $this->processConfiguration( $configuration, $configs );
+
+        // This is the KEY TO YOUR ANSWER
+        $container->setParameter( 'my_nice_project.contact_email', $processedConfig[ 'contact_email' ];
+
+        // Other stuff like loading services.yml
+    }
+```
+
+Then in your config.yml, config_dev.yml and so you can set
+
+```
+my_nice_project:
+    contact_email: [email protected]
+```
+
+To be able to process that config.yml inside your MyNiceBundleExtension you'll also need a Configuration class in the same namespace:
+
+```
+class Configuration implements ConfigurationInterface
+{
+    public function getConfigTreeBuilder()
+    {
+        $treeBuilder = new TreeBuilder();
+        $rootNode = $treeBuilder->root( 'my_nice_project' );
+
+        $rootNode->children()->scalarNode( 'contact_email' )->end();
+
+        return $treeBuilder;
+    }
+}
+```
+
+Then you can get the config from your controller, as you desired in your original question, but keeping the parameters.yml clean, and setting it in the config.yml in separated sections:
+
+```
+$recipient = $this->container->getParameter( 'my_nice_project.contact_email' );
+```
+
+SECOND APPROACH: Separated config block, injecting the config into a service
+-----------------------------------------------------------------------------
+
+For readers looking for something similar but for getting the config from a service, there is even a nicer way that never clutters the "paramaters" common space and does even not need the container to be passed to the service (passing the whole container is practice to avoid).
+
+This trick above still "injects" into the parameters space your config.
+
+Nevertheless, after loading your definition of the service, you could add a method-call like for example setConfig() that injects that block only to the service.
+
+For example, in the Extension class:
+```
+class MyNiceProjectExtension extends Extension
+{
+    public function load( array $configs, ContainerBuilder $container )
+    {
+        $configuration = new Configuration();
+        $processedConfig = $this->processConfiguration( $configuration, $configs );
+
+        // Do not add a paramater now, just continue reading the services.
+        $loader = new YamlFileLoader( $container, new FileLocator( __DIR__ . '/../Resources/config' ) );
+        $loader->load( 'services.yml' );
+
+        // Once the services definition are read, get your service and add a method call to setConfig()
+        $sillyServiceDefintion = $container->getDefinition( 'my.niceproject.sillymanager' );
+        $sillyServiceDefintion->addMethodCall( 'setConfig', array( $processedConfig[ 'contact_email' ] ) );
+    }
+}
+```
+
+Then in your services.yml you define your service as usual, without any absolute change:
+
+```
+services:
+    my.niceproject.sillymanager:
+        class: My\NiceProjectBundle\Model\SillyManager
+        arguments: []
+```
+
+And then in your SillyManager class, just add the method:
+```
+class SillyManager
+{
+    private $contact_email;
+
+    public function setConfig( $newConfigContactEmail )
+    {
+        $this->contact_email = $newConfigContactEmail;
+    }
+}
+```
+
+Note that this also works for arrays instead of scalar values! Imagine that you configure a rabbit queue and need host, user and password:
+```
+my_nice_project:
+    amqp:
+        host: 192.168.33.55
+        user: guest
+        password: guest
+```
+
+Of course you need to change your Tree, but then you can do:
+```
+$sillyServiceDefintion->addMethodCall( 'setConfig', array( $processedConfig[ 'amqp' ] ) );
+```
+and then in the service do:
+```
+class SillyManager
+{
+    private $host;
+    private $user;
+    private $password;
+
+    public function setConfig( $config )
+    {
+        $this->host = $config[ 'host' ];
+        $this->user = $config[ 'user' ];
+        $this->password = $config[ 'password' ];
+    }
+}
+```
+
+Hope this helps!
