title: Catchall Router on Exim does not work
body: <p>I have setup a catchall router on exim (used as last router):</p>
  
  <pre><code>catchall:
    driver = redirect
    domains = +local_domains
    data = ${lookup{*@$domain}lsearch{/etc/aliases}}
    retry_use_local_part
  </code></pre>
  
  <p>This works perfectly when sending emails locally. However, if I login to my GMail account and send an email to whatever@mydomain.com, then I get an "Unrouteable Address".</p>
  
  <p>Thank you for any hints to solve this issue.</p>
