title: sendmail: how to configure sendmail on ubuntu?
body: <p>When I searched for configuring sendmail on ubuntu I din't get any clear answer, each of them assume I know what they are talking about,</p>
  
  <p>I just want basic configuration to enable email sending, basically I will use it with google app engine to enable mail sending from dev server.</p>
  
  <p>I already did this:</p>
  
  <pre><code>sudo apt-get install sendmail
  </code></pre>
  
  <p>then </p>
  
  <pre><code>sudo sendmailconfig
  </code></pre>
  
  <p>but I don't know what the last one actually did.</p>
