title: How to set delivery format while using SMTP client?
body: <p>I am trying to access the <strong>DeliveryFormat</strong> property of the SMPTPClient object while programatically sending email. However, it is not recognized. I checked the MSDN documentation, which do not indicate that it has been deprecated.</p>
  
  <pre><code>SmtpClient smtpClient = new SmtpClient();
  smtpClient.DeliveryFormat = SmtpDeliveryFormat.International; //DeliveryFormat property is not recognised
  </code></pre>
  
  <p>Is there a new way to set the delivery format property?</p>
