从ASP.NET发送邮件

问题描述

亲爱的所有人，

我尝试了许多排列和组合来从ASP发送邮件.

但是结果仍然是负面的.没有错误，但是收件箱中没有邮件.

代码如下.

Dear All,

I tried many permutations and combinations for sending a mail from ASP.

But the result is still negative. There is no error but there is no mail in the inbox.

code is as follows.

protected void Button1_Click(object sender, EventArgs e)
    {
        MailMessage message = new MailMessage();
        SmtpClient smtpClient = new SmtpClient();

        smtpClient.DeliveryMethod = SmtpDeliveryMethod.PickupDirectoryFromIis;

        try
        {
            MailAddress fromAddress = new MailAddress(Textbox2.Text, TextBox1.Text);


            //Default port will be 25

            smtpClient.Port = 25;
            message.From = fromAddress;




            message.To.Add("[email protected]");

            message.IsBodyHtml = false;
            message.Body = TextBox3.Text;
            message.Subject = "test";

            smtpClient.Send(message);



            Label3.Text = "Email Sent";


        }
        catch(Exception ex)

        {
            Label3.Text = "Sending Failed" + ex.Message;


        }


    }

我在web.config中进行了以下更改.

I have made the following changes in web.config.

<system.net>
    <mailSettings>

        <network host="192.168.1.33" port="25" userName="username" password="password" defaultCredentials="true" />

    </mailSettings>

有人可以在这里让我知道主机或SMTP服务器的确切含义吗，它是"smtp.gmail.com"，"localhost"或我的IP地址".

我想我没有正确指定此参数，这就是我面临的问题.

我也想知道是否应提供该用户名和密码????

请协助.

提前致谢.

        <network

          host="localhost"

          port="25"

          defaultCredentials="true"

        />

如果您想通过Gmail实际发送电子邮件，那么我相信您可以将smpt.gmail.com指定为服务器(端口应保持25)，但是您需要提供gmail用户名和密码，而不要使用DefaultCredentials

If you want to actually send your email through Gmail then I believe you can specify smpt.gmail.com as the server (the port should stay on 25) but you''d then need to give your gmail username and password and not use DefaultCredentials
