發送郵件失敗

Question

我正在嘗試創建一個電子郵件頁面部分，並且我在下面的代碼中找到了一篇文章和其中一個答案，但仍然說發送郵件失敗，我幾乎找不到原因？。我需要幫助才能找到補救措施，以解釋爲什麼我的代碼無法發送電子郵件。在這裏我的代碼供您參考。請指教......謝謝。

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(); 
     } 

請糾正我的代碼並告訴我我失蹤了什麼？在此先感謝...

Answer 1

對於發送郵件，您不能使用您的開發服務器端口。

您必須使用郵件服務器的smtp服務器端口。

爲smtp.live.com你應該使用端口25或587

對於下面這段代碼，指定有效的登錄信息（電子郵件/密碼）

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

Answer 2

試試這個。

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); 

Answer 3

只提供G-mail帳號標識然後檢查它。我認爲SmtpClient不接受任何其他域名郵件地址。所以你可以只輸入gmail地址然後檢查它。
