title: Creating appspotmail address to receive eMail in GAE
body: <p>I set up an application in GAE and I want to be able to receive eMails.</p>
  
  <p>The documentation says that:</p>
  
  <blockquote>
    <p>You can set up your app to receive incoming email at
    string@appid.appspotmail.com addresses
    <a href="https://cloud.google.com/appengine/docs/java/mail/#Java_Receiving_mail_in_Java" rel="nofollow">GAE documentation</a></p>
  </blockquote>
  
  <p>I did not found any possibility to create a mail in this form (e.g. <em>service@appid.appspotmail.com</em>) in the application.</p>
  
  <p>Can somebody help me how to set up an appspot mail address and to assign it to the application? (I do not know if I need to assign the address inside the permissions settings of the app or if it is sufficient to only put in the <em>web.xml</em> of the application)</p>
  
  <p>Thank you!</p>
