Question

我正在编写脚本，以将电子邮件从一个帐户迁移到另一个帐户。我有两个问题。

消息正在移动，但是邮件客户端显示了它们收到的日期作为移动的日期/时间（在消息列表中）视图），而不是邮件标题中显示的日期/时间。我是猜猜是否不保留文件日期？

未复制消息标志。如留言已被读取。我希望看到所有标记都通过了...基本上，我需要移动上一个帐户中存在的消息。

protected void CopyBtn_Click(object sender, EventArgs e)
{
    try
    {
        ImapClient Client = new ImapClient();
        ImapClient Client2 = new ImapClient();
        Client.Connect(SourceHostBox.Text.Trim(), 993, SecureSocketOptions.SslOnConnect);
        Client.Authenticate(SourceUsernameBox.Text.Trim(), SourcePasswordBox.Text.Trim());
        Client.Inbox.Open(FolderAccess.ReadWrite);
        Client2.Connect(DestinationHostBox.Text.Trim(), 993, SecureSocketOptions.SslOnConnect);
        Client2.Authenticate(DestinationUsernameBox.Text.Trim(), DestinationPasswordBox.Text.Trim());
        Client2.Inbox.Open(FolderAccess.ReadWrite);

        var folders = Client.GetFolders(Client.PersonalNamespaces[0]);

        //move all messages in folders & create folders if necessary
        foreach (var folder in folders)
        {
            folder.Open(FolderAccess.ReadWrite);
            var uids = folder.Search(SearchQuery.All);

            foreach (var uid in uids)
            {
                var folders2 = Client2.GetFolders(Client2.PersonalNamespaces[0]);
                var message = folder.GetMessage(uid);
                string currentFolder = folder.ToString().Replace("INBOX.", ""); //Remove the 'INBOX.' text that's getting prepended by cPanel/Dovecot

                var toplevel = Client2.GetFolder(Client2.PersonalNamespaces[0]);
                var folderExists = FindFolder(toplevel, currentFolder);
                if (folderExists == null)
                    toplevel.Create(currentFolder, true);
                Client2.GetFolder(currentFolder).Append(message);
            }
        }

        //move inbox messages
        Client.Inbox.Open(FolderAccess.ReadWrite);
        Client2.Inbox.Open(FolderAccess.ReadWrite);
        var inboxuids = Client.Inbox.Search(SearchQuery.All);
        foreach (var uid in inboxuids)
        {
            var message = Client.Inbox.GetMessage(uid);
            Client2.Inbox.Append(message);
        }

        label1.Text = "Finished Successfully.";
        label1.ForeColor = System.Drawing.Color.Green;

    }
    catch (Exception ex)
    {
        label1.Text = ex.Message;
        label1.ForeColor = System.Drawing.Color.Red;
    }
}

您需要使用其他Append()方法之一，该方法需要一个MessageFlags参数和一个DateTimeOffset参数来指定消息到达的时间戳。

但是为了获取该信息，您还需要Fetch()的每条消息的元数据。

这是我要更改循环的方式：

var inboxuids = Client.Inbox.Search(SearchQuery.All);
foreach (var uid in inboxuids)
{
    var message = Client.Inbox.GetMessage(uid);
    Client2.Inbox.Append(message);
}

已修复：

var uids = Client.Inbox.Search (SearchQuery.All);
var items = Client.Inbox.Fetch (uids, MessageSummaryItems.InternalDate | MessageSummaryItems.Flags);
foreach (var item in items)
{
    var message = Client.Inbox.GetMessage (item.UniqueId);

    Client2.Inbox.Append (message, item.Flags.Value, item.InternalDate.Value);
}

MailKit：邮件客户端显示的是移动时收到的消息，并且不保留原始标志
