發送郵件失敗：{「遠程名稱無法解析：'smtp.live.com'}}

我得到」遠程名稱無法解析：'smtp.live.com'「異常不斷從過去2小時試圖發送簡單的郵件。這裏是我的代碼：發送郵件失敗：{「遠程名稱無法解析：'smtp.live.com'}}

  MailMessage mailMessage = new MailMessage(); 
      mailMessage.From = new MailAddress("[email protected]", "Some Name"); 
      mailMessage.To.Add(new MailAddress("[email protected]")); 
      mailMessage.IsBodyHtml = true; 
      mailMessage.Body = "<b>This is a check email</b>"; 
      mailMessage.Subject = "Test subject"; 

      SmtpClient smtpClient = new SmtpClient(); 
      smtpClient.Port = 587; //also tried 25 and 465 
      smtpClient.Host = "smtp.live.com"; //also tried smtp-mail.outlook.com 
      smtpClient.EnableSsl = true; 
      smtpClient.UseDefaultCredentials = false; //also tried removing the credentials and setting this to true 
      smtpClient.Credentials = new NetworkCredential("[email protected]", "its password"); 

      smtpClient.Send(mailMessage); 

      Console.WriteLine("Success");

只是出於好奇，我曾嘗試加入smtp.gmail.com到主機並輸入我的Gmail憑證爲好，但也不能工作。這裏的痕跡：

這裏是NSLOOKUP顯示我要smtp.live.com：

我的Internet連接使用代理地址和端口8080，是什麼問題？請爲我的具體問題提供解決方案，我已經嘗試了所有可用的互聯網通用解決方案。

您是否也使用smtp代理？ –

您的郵件憑據是否有效？ –

好吧，它甚至沒有嘗試建立連接，但它沒有解決IP - 所以顯然它花了太長的時間來解決..如果你有一個http代理，你可能/幾乎肯定會遇到防火牆問題，機會端口是不是打開你的機器直接通話 – BugFinder

看起來您的網絡設置存在問題，或者防火牆阻止了郵件服務器。代碼看起來很好。

嘗試用跟蹤ping主機名並查看是否有效

是的，我向我的網絡管理員詢問了這個問題，他向我保證，其他smtp不能從我們的網絡訪問。他們被阻止 –

請將此標記爲答案，以便這可能有助於任何未來有同樣問題的人。謝謝 –

正確檢查互聯網連接，然後重試。這對我有效。

問題中的詳細信息表明這不是互聯網連接問題 – EvilGeniusJamie
