+How to use the Cloud to Send Emails
+===================================
+
+Requirements for sending emails from a production system differ from your
+development setup as you don't want to be limited in the number of emails,
+the sending rate or the sender address. Thus,
+:doc:`using Gmail </cookbook/email/gmail>`_ or similar services is not an
+option. If setting up and maintaining your own reliable mail server causes
+you a headache there's a simple solution: Leverage the cloud to send your
+emails.
+
+This cookbook shows how easy it is to integrate
+`Amazon's Simple Email Service (SES)`_ into Symfony.
+
+.. note::
+
+    You can use the same technique for other mail services, as most of the
+    time there is nothing more to it than configuring an SMTP endpoint for
+    Swift Mailer.
+
+In the Symfony configuration, change the Swift Mailer settings ``transport``,
+``host``, ``port`` and ``encryption`` according to the information provided in
+the `SES console`_. Create your individual SMTP credentials in the SES console
+and complete the configuration with the provided ``username`` and ``password``:
+
+.. configuration-block::
+
+    .. code-block:: yaml
+
+        # app/config/config.yml
+        swiftmailer:
+            transport:  smtp
+            host:       email-smtp.us-east-1.amazonaws.com
+            port:       465 # different ports are available, see SES console
+            encryption: tls # TLS encryption is required
+            username:   AWS_ACCESS_KEY  # to be created in the SES console
+            password:   AWS_SECRET_KEY  # to be created in the SES console
+
+    .. code-block:: xml
+
+        <!-- app/config/config.xml -->
+        <?xml version="1.0" encoding="UTF-8" ?>
+        <container xmlns="http://symfony.com/schema/dic/services"

+
+            <!-- ... -->
+            <swiftmailer:config
+                transport="smtp"
+                host="email-smtp.us-east-1.amazonaws.com"
+                port="465"
+                encryption="tls"
+                username="AWS_ACCESS_KEY"
+                password="AWS_SECRET_KEY"
+            />
+        </container>
+
+    .. code-block:: php
+
+        // app/config/config.php
+        $container->loadFromExtension('swiftmailer', array(
+            'transport'  => 'smtp',
+            'host'       => 'email-smtp.us-east-1.amazonaws.com',
+            'port'       => 465,
+            'encryption' => 'tls',
+            'username'   => 'AWS_ACCESS_KEY',
+            'password'   => 'AWS_SECRET_KEY',
+        ));
+
+The ``port`` and ``encryption`` keys are not present in the Symfony Standard
+Edition configuration by default, but you can simply add them as needed.
+
+And that's it, you're ready to start sending emails through the cloud!
+
+.. tip::
+
+    If you are using the Symfony Standard Edition, configure the parameters in
+    ``parameters.yml`` and use them in your configuration files. This allows
+    for different Swift Mailer configurations for each installation of your
+    application. For instance, use Gmail during development and the cloud in
+    production.
+
+    .. code-block:: yaml
+
+        # app/config/parameters.yml
+        parameters:
+            # ...
+            mailer_transport:  smtp
+            mailer_host:       email-smtp.us-east-1.amazonaws.com
+            mailer_port:       465 # different ports are available, see SES console
+            mailer_encryption: tls # TLS encryption is required
+            mailer_user:       AWS_ACCESS_KEY # to be created in the SES console
+            mailer_password:   AWS_SECRET_KEY # to be created in the SES console
+
+.. note::
+
+    If you intend to use Amazon SES, please note the following:
+
+        * You have to sign up to `Amazon Web Services (AWS)`_;
+
+        * Every sender address used in the ``From`` or ``Return-Path`` (bounce
+          address) header needs to be confirmed by the owner. You can also
+          confirm an entire domain;
+
+        * Initially you are in a restricted sandbox mode. You need to request
+          production access before being allowed to send to arbitrary
+          recipients;
+
+        * SES may be subject to a charge.
