c# - 由于 IMAP 实现中出现意外的数据包格式，握手失败

Question

我试图通过 c# 代码阅读我的邮件收件箱，但它给出了一个错误“由于意外的数据包格式，握手失败”。

这是我的代码，

   using AE.Net.Mail;
   using System;
   using System.Collections.Generic;
   using System.IO;
   using System.Linq;
   using System.Text;
   using System.Threading.Tasks;

   namespace MailApp
   {
   class Program
   {
     static void Main(string[] args)
     {

         try
         {
             ImapClient ic = new ImapClient("mail.topformtechnologies.com", "username@topformtechnologies.com", "password", AuthMethods.Login, 143, true);

            // Select a mailbox. Case-insensitive
            ic.SelectMailbox("INBOX");
            Console.WriteLine(ic.GetMessageCount());
            Console.ReadLine();
            // Get the first *11* messages. 0 is the first message;
            // and it also includes the 10th message, which is really the eleventh ;)
            // MailMessage represents, well, a message in your mailbox
            MailMessage[] mm = ic.GetMessages(0, 10);
            foreach (MailMessage m in mm)
            {
                Console.WriteLine(m.Body);
                Console.ReadLine();

            }
                ////            SmtpServer.Send(mail);
        }
        catch (Exception e)
        {
            Console.WriteLine(e);
            Console.ReadLine();
        }
    }
}

}

这是详细的错误：

System.IO.IOException：由于意外的数据包格式，握手失败。在 System.Net.Security.SslState.StartReadFrame(Byte[] buffer, Int32 readBytes, AsyncProtocolRequest asyncRequest) 在 System.Net.Security.SslState.StartReceiveBlob(Byte[] buffer, AsyncProtocolRequest asyncRequest) 在 System.Net.Security.SslState。 CheckCompletionBeforeNextReceive(ProtocolToken message, AsyncProtocolRequest asyncRequest) at System.Net.Security.SslState.StartSendBlob(Byte[] incoming, Int32 count, AsyncProtocolRequest asyncRequest) at System.Net.Security.SslState.ForceAuthentication(Boolean receiveFirst, Byte[] buffer, AsyncProtocolRequest asyncRequest) 在 System.Net.Security.SslState.ProcessAuthentication(LazyAsyncResultlazyResult) 在 System.Net.Security.SslStream.AuthenticateAsClient(String targetHost,

请有人指导我解决这个问题。

提前致谢。
