使用{ System.Net.Mail }发送邮件

Question

        SmtpClient client = new SmtpClient();
        client.Port = 587;
        client.Host = "smtp.gmail.com";
        client.EnableSsl = true;
        client.Timeout = 10000;
        client.DeliveryMethod = SmtpDeliveryMethod.Network;
        client.UseDefaultCredentials = false;
        client.Credentials = new System.Net.NetworkCredential("*********@gmail.com", "***********");

        MailMessage mm = new MailMessage("*********@gmail.com", "******@gmail.com", "delivery.", "tttt");
        mm.BodyEncoding = UTF8Encoding.UTF8;
        mm.DeliveryNotificationOptions = DeliveryNotificationOptions.OnFailure;

            Attachment fMailAttachment;
            fMailAttachment = new Attachment(FilePath);
            mm.Attachments.Add(fMailAttachment);

            client.Send(mm);
            mm.Attachments.Dispose();

我试图用这段代码发送一封电子邮件。它运行良好，但只有当我登录我的邮件，让它打开，当我关闭邮件，它不发送任何邮件。

那个代码有什么问题？

在我编辑了client.Timeout = 10000；client.Timeout =100000之后，它工作得很好；
