通过云

Question

我已将我的网站部署到azure云，我正在尝试向客户端发送电子邮件。当我在本地主机上测试它时，它可以正常工作，但在移动到云时，它会显示有时出现的几个错误：

- ＆GT;连接超时，我已将超时声明为150000

- ＆gt; SMTP服务器需要安全连接，或者客户端未经过身份验证。服务器响应为：5.5.1需要身份验证。 （我已将不太安全的应用程序允许邮寄帐户）

这里我附上了我的代码。请查看它并建议解决方法。 提前谢谢大家。

protected void Button2_Click(object sender, EventArgs e)
{

    MailMessage msg = new MailMessage();
    MailAddress from = new MailAddress("bvpcsccloud@gmail.com");
    MailAddress to = new MailAddress(Label7.Text);
    string subjectText = "E-appointment request";
    string bodyText = @"Hi, This mail is for the request of e-appointment from our patient:"+TextBox4.Text.ToString()+"<br />"+ "The patient has age:";
    bodyText +=  TextBox5.Text.ToString()+"<br /> Disease symbols are"+TextBox2.Text.ToString()+"<br /> Disease name:"+ TextBox3.Text.ToString();
    bodyText += "<br />Patient address is" + TextBox1.Text.ToString();
    bodyText += "<br /> preffered date choosen by patient is" + DropDownList1.SelectedItem.Text + "-" + DropDownList2.SelectedItem.ToString() + "-" + DropDownList3.SelectedItem.Text;
    msg.To.Add(to);
    msg.From = from;
    msg.Subject = subjectText;
    msg.Body = bodyText;
    msg.IsBodyHtml = true;
    SmtpClient smtp = new SmtpClient();
    smtp.Host = "smtp.gmail.com";
    smtp.Port = 587;



   //smtp.DeliveryMethod = SmtpDeliveryMethod.Network;
    smtp.Credentials = new System.Net.NetworkCredential("bvpcsccloud@gmail.com", "password");

    //smtp.UseDefaultCredentials = false;
    try
    {
        smtp.EnableSsl = true;
        smtp.Timeout = 150000;
        smtp.Send(msg);

        smtp.Dispose();
        Response.Redirect("~/appointment_booked.aspx");
    }
    catch (Exception ex)
    {
        throw ex;

    }
}
