title: Resolving 'The specified string is not in the form required for a subject.'
body: <p>I have a class that sends an Email (MailMessage) but I get the following error:</p>
  
  <blockquote>
    <p>"The specified string is not in the form required for a subject."</p>
  </blockquote>
  
  <p>Is there a handy dandy method to sanitize the strings or do I have to write my own?</p>
