Convert MSG File to EML and Preserve RTF Content

This code demonstrates how to load a MSG file, convert it to EML format, and preserve RTF content.

   var loadOptions = new MsgLoadOptions
   {
       PreserveRtfContent = true
   };

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

   var conversionOptions = new MailConversionOptions
   {
       PreserveRtfContent = true

This code demonstrates how to retrieve messages asynchronously from an IMAP server using Aspose.Email.

   List<MailMessage> mailMessages = new List<MailMessage>();

   // create mail messages
   for (int i = 0; i < 100; i++)
       mailMessages.Add(new MailMessage(senderEmail, receiverEmail, $"Message #{i}", "Text"));

   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.");
           }
           catch (Exception ex)
