推荐答案

您错过了一个重要属性.

只需在下面添加行

You missed one important property.

Just add the line below

client.UseDefaultCredentials = false;

之前

before

client.Credentials = new System.Net.NetworkCredential("[e-mail]", 

这样的代码看起来就像是

So the code will look like,

client.UseDefaultCredentials = false;
client.Credentials = new System.Net.NetworkCredential("[e-mail]", 
....

让我知道它是否可以解决您的目的.

欢呼

Let me know if it solves your purpose.

您没有显示发生的错误

You are not displaying the error that happens

try
        {
            client.Send(mail);
            lblmsg.Text = "Email Sent Successfully...";
        }
        catch
        {

        }

做这个

do this

try
        {
            client.Send(mail);
            lblmsg.Text = "Email Sent Successfully...";
        }
        catch(Exception ex)
        {
            string str_ex = ex.Message;
            lblmsg.Text = str_ex;
        }

我在这里猜测，但我敢打赌，您的问题是生产服务器上的防火墙.它可能不允许通过端口587进行通信

I''m taking a guess here but I bet your problem is your firewall on your production server. It is probably not allowing communication through on port 587

在您的服务器中启动了smtp吗?

In your server have you start the smtp ?
