Question

在我的项目中，我实施了Forgot password功能，用户输入他/她的Email-Id ID并提交按钮。然后，他将在已注册的电子邮件ID上收到他的ID和密码详细信息。

这一切功能在我的本地服务器上正常运行。但是当我将它集成到服务器时，它会给我带来错误

连接尝试失败，因为连接方在一段时间或建立的连接后没有正确响应失败，因为已连接的主机无法响应74.125.68.109:587

我也试过这个link，但它没有帮助我，并且得到了同样的错误。

这是我的Send Mail代码： -

protected void btnSubmit_Click(object sender, EventArgs e)
    {
        DataSet ds = new DataSet();
        using (SqlConnection conn = new SqlConnection(System.Configuration.ConfigurationManager.ConnectionStrings["DefaultCSRConnection"].ConnectionString))
        {
            conn.Open();
            SqlCommand cmd = new SqlCommand("SELECT username,password FROM tbl_User Where email= '" + txtEmail.Text.Trim() + "'", conn);
            SqlDataAdapter da = new SqlDataAdapter(cmd);
            da.Fill(ds);
            conn.Close();
            if (ds.Tables[0].Rows.Count > 0)
            {
                MailMessage Msg = new MailMessage();
                // Sender e-mail address.
                Msg.From = new MailAddress(txtEmail.Text);
                // Recipient e-mail address.
                Msg.To.Add(txtEmail.Text);
                Msg.Subject = "Password Details";
                Msg.Body = "Hi, <br/>Your login details are<br/><br/>Your Username is: " + ds.Tables[0].Rows[0]["username"] + "<br/><br/>Your Password is: " + Decrypt(ds.Tables[0].Rows[0]["password"].ToString()) + "<br/><br/>";
                Msg.IsBodyHtml = true;
                // your remote SMTP server IP.
                SmtpClient smtp = new SmtpClient();
                smtp.Host = "smtp.gmail.com";
                smtp.Port = 587;
                smtp.Credentials = new System.Net.NetworkCredential("mygmailid", "**********");
                smtp.EnableSsl = true;
                smtp.Send(Msg);
                Msg = null;
                //lbltxt.Text = "Your Password Details Sent to your mail";
                ScriptManager.RegisterStartupScript(this, this.GetType(), "alert", "alert('Your Password Details Sent to your mail');window.location ='Login.aspx';", true);
                // Clear the textbox valuess
                txtEmail.Text = "";
            }
            else
            {
                Response.Write("<script>alert('Email Id you entered does not exist');</script>");
            }
        }
    }

请提出可能存在的问题。
