Question

我想在点击提交按钮时发送邮件通知。单击按钮时，标签显示your message has been sent。但是当我检查我的邮件时，我没有收到那封邮件。

这是我的代码：

  protected void btnSubmit_Click(object sender, EventArgs e)
    {
        try
        {
            //Create the msg object to be sent
            MailMessage msg = new MailMessage();
            //Add your email address to the recipients
            msg.To.Add("sathishsatu222@gmail.com");
            //Configure the address we are sending the mail from **- NOT SURE IF I NEED THIS OR NOT?**
            MailAddress address = new MailAddress("satheezkumar93@gmail.com");
            msg.From = address;
            //Append their name in the beginning of the subject
            msg.Subject = "hy";
            msg.Body = "hy hw ru?";
            SmtpClient client = new SmtpClient("smtp-mail.gmail.com", 25);
            NetworkCredential credentials = new NetworkCredential("satheezkumar93@gmail.com", "mypassword here");
            client.Credentials = credentials;
            client.Host = "smtp-mail.gmail.com";
            client.Port = 25;
            client.EnableSsl = true;
            //Configure an SmtpClient to send the mail.


            //Display some feedback to the user to let them know it was sent
            lblResult.Text = "Your message was sent!";


        }
        catch
        {
            //If the message failed at some point, let the user know
            lblResult.Text = "Your message failed to send, please try again.";
        }
    }

Answer 1

您需要实际发送消息：

client.Send(msg);

作为旁注，似乎您将SmtpClient配置为端口25并使用SSL，尽管可能（不使用gmail），但这并不常见。

由于您使用的是gmail，因此您应该启用ssl（您已经这样做了），并使用端口587，而不是25（执行client.Port = 587;，或删除该行并更改25 in 587）的构造函数。

另外，我认为Gmail主机是smtp.gmail.com，而不是smtp-mail.gmail.com

最简单的邮件方法

protected void btnEmail_Click(object sender, EventArgs e)
    { 
        vr txtmsg = "hello";
        var ToMail ="someone@some.com";

        using (MailMessage mm = new MailMessage(txtmsg , ToMail ))
        {
            mm.Subject ="Comments";
            mm.Body = "body text";

            mm.IsBodyHtml = false;
            SmtpClient smtp = new SmtpClient();
            smtp.Host = "yourhost";
            smtp.EnableSsl = true;
            //Provide those
            NetworkCredential NetworkCred = new NetworkCredential("username","pass");
            smtp.UseDefaultCredentials = true;
            smtp.Credentials = NetworkCred;
            smtp.Port = 587;
            smtp.Send(mm);
            Response.Write("<script>alert('Mail Sent')</script>");
        }
    }

Gmail不允许未经授权的登录发送邮件。

请检查OAuth以发送邮件。
