title: exim configuration - accept all mail
body: <p>I've just set up exim on my ubuntu computer. At the moment it will only accept email for accounts that exist on that computer but I would like it to accept all email (just because I'm interested). Unfortunately there seem to be a million exim related config files, and I'm not having much success finding anything on google.</p>
  
  <p>Is there an introduction to exim for complete beginners?</p>
  
  <p>Thanks.</p>
