title: Installing and configuring a barebones email server on Ubuntu
body: <p>I've got an unmanaged Linux VPS running ubuntu that I'm using for the web server for a personal website.  I'd like to get a barebones email server up and running.  All the installation guides I've found so far are for a full-fledged email server with a webmail interface and everything.  That's a lot more than I need.  There's only two things I need:</p>
  
  <ul>
  <li>My web application needs to be able to send email.  Specifically, it'll be emailing me when an exception occurs.</li>
  <li>I want all email sent to [anything]@domain.com forwarded to my personal gmail account.  The server doesn't even need to retain the email or anything.</li>
  </ul>
  
  <p>I want to reserve resources for the actual web app, so I don't want to install anything I won't need for this.</p>
