title: Amazon SES: email address cannot be found
body: <p>I am trying to send an email via Amazon SES.</p>
  
  <p>I have <code>MX</code> record for <code>mydomain.com</code> as shown below:</p>
  
  <pre><code>$ dig mx mydomain.com +noall +answer +nocomments
  
  ; &lt;&lt;&gt;&gt; DiG 9.10.3-P4-Ubuntu &lt;&lt;&gt;&gt; mx mydomain.com +noall +answer +nocomments
  ;; global options: +cmd
  mydomain.com.       2719    IN  MX  10 inbound-smtp.eu-west-1.amazonaws.com.
  </code></pre>
  
  <p>However, when sending to e.g. <code>someone@mydomain.com</code>, I get:</p>
  
  <blockquote>
    <p>The email address you entered couldn't be found. Please check the recipient's email address and try to resend the message. If the problem continues, please contact your helpdesk.</p>
  </blockquote>
  
  <p>I also have a hosted zone for <code>mydomain.com</code> </p>
  
  <p>What should I  do for troubleshooting this?</p>
