 var loadOptions = new MsgLoadOptions
 {
 PreserveRtfContent = true
 };

 var eml = MailMessage.Load("my.msg", loadOptions);

 using (ImapClient client = new ImapClient(host, 993, senderEmail, password, SecurityOptions.SSLImplicit))
 {
 CancellationTokenSource cancellationTokenSource = new CancellationTokenSource();
 AutoResetEvent autoResetEvent = new AutoResetEvent(false);
 Exception exception = null;

 ThreadPool.QueueUserWorkItem(delegate
 {
 try
 {
 // start uploading the messages
 var task = client.AppendMessagesAsync(mailMessages, cancellationTokenSource.Token);
 AppendMessagesResult appendMessagesResult = task.GetAwaiter().GetResult();
 Console.WriteLine("All messages have been appended.");
