title: How to exit from linux sendmail on centos 6
body: <p>I was looking up something here on stack overflow and the answer told me to enter </p>
  
  <pre><code>sendmail -bt
  </code></pre>
  
  <p>in the shell. I was able to do what the question said but now I'm unable to exit the sendmail program. <code>CTRL+c, CTRL+x, q, exit, bye, quit</code> does not seem to work. How do you exit the sendmail program once your in without terminating my ssh connection?</p>
