title: sent folder empty using mailkit
body: <p>I am trying to get the sent folders to display but it shows that the folder has no children in it. All folders are empty except inbox. I am using the following code.</p>
  
  <pre><code>using (var client = new ImapClient())
  {
     client.Connect(credentials.incoming_host, (int)credentials.incoming_port, credentials.incoming_ssl); //for SSL
     client.Authenticate(credentials.email, credentials.password);
     client.Inbox.Open(FolderAccess.ReadOnly);
  
     var sentFolder= client.GetFolder(MailKit.SpecialFolder.Sent);
     var Folders = client.GetFolders(client.PersonalNamespaces[0]);
  
     client.Disconnect(true);
  }
  </code></pre>
  
  <p>I tried sending an email using the same folder, and then append it like:</p>
  
  <pre><code>var sentFolder = imapclient.GetFolder(SpecialFolder.Sent);
  sentFolder.Append(message);
  </code></pre>
  
  <p>My outlook did detect it and added into the sent folder.</p>
