title: Redirect mail with AWS route 53 mx records
body: <p>I have two domains:</p>
  <ol>
  <li><p>mydomain.fi using AWS Route 53 DNS</p>
  </li>
  <li><p>mydomain.com hosted on hostmonster</p>
  </li>
  </ol>
  <p>I am trying to set up an email address for mydomain.fi. Instead of installing a email server on EC2 or purchasing a Google Apps account my idea was to redirect mail to mydomain.fi to my other domain on hostmonster.</p>
  <p>From hostmonster's DNS zone edit I found the records:</p>
  <blockquote>
  <p><strong>MX:</strong></p>
  <p><em>0 @   mail.mydomain.com   14400</em></p>
  <p><strong>TXT:</strong></p>
  <p><em>@ v=spf1 a mx ptr include:hostmonster.com ?all    14400</em></p>
  </blockquote>
  <p>I added these to the Route 53 records of mydomain.fi</p>
  <p>When testing by sending an email,  myname@mydomain.com gets delivered but</p>
  <p>myname@mydomain.fi generates the error:</p>
  <blockquote>
  <p><em>Technical details of permanent failure: Google tried to deliver your
  message, but it was rejected by the server for the recipient domain
  mydomain.fi by mail.mydomain.com. [xx.xx.xx.xx].</em></p>
  <p><em>The error that the other server returned was: 550 No Such User Here</em></p>
  </blockquote>
  <p>I tried changing MX settings from Local to Remote in Hostmonster's setting but this had no effect.</p>
  <p>What additional settings are needed in Route 53 / Hostmonster to complete the task?</p>
