 The spam detection agent on the Cloudron requires training to identify spam. To do this, simply move your junk mails
 to a pre-created folder named `Spam`. Most mail clients have a Junk or Spam button which does this automatically.

+## Mail relay
+
+By default, Cloudron's built-in email server sends out email directly to recipients. You can instead configure
+the Cloudron to hand all outgoing emails to a 'mail relay' and have the relay deliver it to recipients. Such a
+setup is useful when the Cloudron server does not have a good IP reputation for mail delivery or if server service provider does not allow sending email via port 25 (which is the case with Google Cloud and Amazon EC2).
+
+Cloudron can be configured to send all outbound email via Amazon SES, Google, Mailgun, Postmark,
+Sendgrid or any other external SMTP server. To setup a relay, enter the relay credentials in the Email section. Cloudron only supports relaying via the STARTTLS mechanism (usually port 587).
