Question

我正在尝试制作一个电子邮件页面部分，我在这个论坛中找到了一篇文章和一个答案，我在下面的代码中使用但是仍然说发送邮件失败，我几乎找不到原因？我需要协助找到解决方法，为什么我的代码无法发送电子邮件。这里我的代码在下面供您参考。请指教......谢谢。

protected void Button1_Click(object sender, EventArgs e)
{

SmtpClient client = new SmtpClient();

        client.Host = "smtp.live.com"; //Im not sure about this,I just copy it from the article
        client.Port = 4548; //This is my ASP.Net Development Server Port,Im not sure also if this is correct.

        client.Credentials = new System.Net.NetworkCredential(
            @"email_account",
            @"email_password"); //Im not sure about this code if this correct, I just copy it


        client.EnableSsl = true;

        // create message
        MailMessage message = new MailMessage();
        message.From = new MailAddress(TextBox4.Text, "Mackmellow"); //Textbox4 is my email address
        message.To.Add(new MailAddress(TextBox1.Text, "Mackmellow")); // Textbox1 is the email add I want to send
        message.Subject = TextBox2.Text; //Textbox2 is my subject
        message.Body = TextBox3.Text; // Textbox3 is my message
        message.BodyEncoding = System.Text.Encoding.UTF8;
        message.IsBodyHtml = true;

        message.SubjectEncoding = System.Text.Encoding.UTF8;


        // send message
        try
        {
            client.Send(message);


        }
        catch (SmtpException ex)
        {

            Response.Write(ex.Message);
        }
        finally
        {
            // Clean up.
            message.Dispose();
        }

请纠正我的密码并告诉我我错过了什么？提前谢谢......

Answer 1

要发送邮件，您无法使用开发服务器端口。

您必须使用邮件服务器的smtp服务器端口。

对于smtp.live.com，您应该使用端口25或587

对于以下代码，请指定VALID登录详细信息（电子邮件/密码）

  client.Credentials = new System.Net.NetworkCredential(
            @"email_account",
            @"email_password");

Answer 2

仅提供G-mail帐户ID。然后检查它。我认为SmtpClient不接受任何其他域名邮件地址。所以你只能放gmail地址，然后检查它。

Answer 3

试试这个。

SmtpClient SmtpServer = new SmtpClient("smtp.live.com");
    var mail = new MailMessage();
    mail.From = new MailAddress("email@hotmail.com");
    mail.To.Add("ToGmail.com");
    mail.Subject = "Your Sub";
    mail.IsBodyHtml = true;
    string htmlBody;
    htmlBody = "HTML code";
    mail.Body = htmlBody;
    SmtpServer.Port = 587;
    SmtpServer.UseDefaultCredentials = false;
    SmtpServer.Credentials = new System.Net.NetworkCredential("email@hotmail.com", "YourPassword");
    SmtpServer.EnableSsl = true;
    SmtpServer.Send(mail);

邮件发送失败
