title: What does MailMessage.IsBodyHtml do?
body: <p>I'm testing sending out some emails via C#, but I can't tell what effect setting <code>IsBodyHtml</code> to <code>true</code> has.  Regardless of the value, whatever I send in my Body shows up with a content type of "text/plain", and my HTML shows up tags and all in my email client (gmail).  What is that flag actually supposed to do?</p>
  
  <p>NOTE: I can send an HTML email just fine by creating an <code>AlternateView</code> with a content type of "text/html", I just want to understand how setting the body is supposed to work.</p>
