+==========================================
+Create Project's Tasks from an Email Alias
+==========================================
+
+When you already have an email address that customers know from the top of their heads, changing
+it is the last thing you want to do. Instead, link that address to your project and transform
+those conversations into structured work. It automatically creates a task in the first stage
+of a project.
+
+Set up an incoming email server
+===============================
+
+| On the *Settings* application, enable *External Email Servers* and define the incoming email
+  alias you would like to use.
+| **For more information**: :doc:`../../discuss/email_servers`
+
+Configure the email alias in your project
+-----------------------------------------
+
+| Now that you have the incoming email server set up, go to
+  :menuselection:`Project --> Configuration --> Projects --> Edit`. Under the *Emails* tab, define
+  the wanted email alias and choose the policy to receive a message.
+| In addition, you can now directly set it when creating a new project.
