title: Send mail using Redemption (RDO)
body: <p>I am using Redemption (<code>RDO</code>) to send an e-mail. The mailing works just fine, but when in Outlook the mail is received, the yellow envelope keeps closed. Normally you click on an unopened e-mail and then the icon change from a yellow closed envelope to a white opened envelope. When I send an e-mail using <code>RDO</code> the envelope stays yellow and closed.</p>
  
  <p>How can I suppress that the envelope goes open?</p>
  
  <p>Here is my code:</p>
  
  <pre><code>RDOSessionClass rdoSession = new RDOSessionClass();
  rdoSession.LogonExchangeMailbox("username", "server");
  
  // Create mail object and send mail
  RDOMailClass m = (RDOMailClass)rdoSession.GetSharedDefaultFolder("user", rdoDefaultFolders.olFolderInbox).Items.Add("IPM.Mail");
  m.Recipients.Add(_mail.Recipient);
  m.Recipients.ResolveAll(null, null);
  m.Subject = _mail.Subject;
  m.Body = _mail.Body;
  m.SenderEmailAddress = "email@address.domain";
  m.Send();
  </code></pre>
