[J1nx]

Describe the bug
I implement the migration mail function by Mailkit,when I calculate the mail count, I find the mail count is error, some mail lossed,but I use the other ImapClient like foxmail, it can read all mails correctly.Can you offer the method of the problem solved?

Platform (please complete the following information):

• OS: Windows11
• .NET Runtime: CoreCLR
• .NET Framework: .NetCore 8.0
• MailKit Version: 4.2.0

Exception
ImapClient can not read mail correctly

// Add your code snippet here.
private static void GetMailByFolder(IMailFolder folder)
    {
        folder.Open(FolderAccess.ReadOnly);


        var uids = folder.Search(SearchQuery.Uids(new UniqueIdRange(UniqueId.MinValue, UniqueId.MaxValue)));

        foreach (var uid in uids.OrderBy(it => it.Id))
        {
            var msg = folder.GetMessage(uid);
            var fileStream = new FileStream($"{uid}.eml", FileMode.OpenOrCreate);
            msg.WriteTo(fileStream);
        }
    }

You should use folder.Search(SearchQuery.All);

Outside of that, you don't really explain the problem. If MailKit doesn't "see" it, then it's 100% guaranteed to be a server bug.
