IMAP S22.IMAP在服务器之间复制邮件

Question

我正在使用一种工具来迁移服务器之间的协议。

我正在使用S22.IMAP dll，但是当我调用Client.CopyMessages（mailIDs，Client2.DefaultMailbox）时，它

在初始帐户中创建邮件（复制邮件而不复制到其他帐户服务器）..

任何人都可以帮助我吗？谢谢 这是我的代码：

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using S22.Imap;
using System.Net.Mail;

namespace ImapPrueba1
{
    public partial class Form1 : Form
    {
        private static IEnumerable<MailMessage> messages;
        private static ImapClient imapClient = null;
        private static IEnumerable<string> mailboxes, mailboxes2;
        private static IEnumerable<uint> mailIDs;
        private static MailMessage mailMessage;

        public Form1()
        {
            InitializeComponent();
        }

        private void Form1_Load(object sender, EventArgs e)
        {

            using (ImapClient Client = new ImapClient("correo.correo.com", 993,
             "correo@correo.es", "xxxxxx", AuthMethod.Login, true))
            {
                ImapClient Client2 = new ImapClient("correonuevo.correonuevo.com", 993,
                    "correo@correo.es", "xxxxxx", AuthMethod.Login, true);
                mailboxes = Client.ListMailboxes();
                string mailbox, mailbox2;
                for (int i = 0; i <  mailboxes.Count(); i++) {
                    mailbox = mailboxes.ElementAt(i);
                    Client.DefaultMailbox = mailbox;
                    mailIDs = Client.Search(SearchCondition.All());
                    messages = Client.GetMessages(mailIDs);
                    //check the folder isn't in the destiny
                    mailboxes2 = Client2.ListMailboxes();
                    IEnumerable<string> items = mailboxes2.Where(p => p.Equals(mailbox));
                    int total = items.Count();
                    if (total == 0)
                    {
                        // set the folder in the destiny
                        Client2.CreateMailbox(mailbox);
                    }

                    Client2.DefaultMailbox = mailbox;
                    if (mailIDs.Count() > 0)
                    {
                        //copy to the destiny
                        Client.CopyMessages(mailIDs, Client2.DefaultMailbox);
                    }


                }

                label1.Text = "cambio";
            }

        }



    }
