ASP.NET交換服務器發送電子郵件C＃

好的，只要我輸入這個，我注意到可能涵蓋相同問題的變體主題。我拜訪了他們中的大多數，發現與我所要求的沒有直接關係，所以我要求耐心。ASP.NET交換服務器發送電子郵件C＃

無論如何，我正在使用VS2010創建一個ASP.NET Web應用程序。我想使用的代碼通過SMTP發送電子郵件：

 MailMessage mailMsg = new MailMessage(); 

     mailMsg.From = new MailAddress(fromEmail); 
     mailMsg.To.Add(toEmail); 
     mailMsg.Subject = emailSubj.ToString().Trim(); 
     mailMsg.Body = msgBody.ToString().Trim(); 
     SmtpClient smtpClient = new SmtpClient(); 
     smtpClient.Send(mailMsg);

但每次我得到下面的異常（SMTPException和的InnerException說{"Unable to connect to the remote server"}

我也定義在web.config如下：

<system.net> 
    <mailSettings> 
    <smtp> 
     <network host="company.com"/> 
    </smtp> 
    </mailSettings> 
</system.net>

我想要做的是發送一封電子郵件，一旦提交表單與請求ID，以便它可以通過其他頁面訪問（除郵件以外的所有作品）在我們使用的公司交換服務器，當我去我的合作ntact屬性我得到smtp:[email protected]

那麼這裏要做什麼？我檢查Web Services ExchangeServiceBinding但不能真正直接找東西幫我（所以任何鏈接讚賞）

非常感謝，並期待着閱讀您的答覆:)

談談您的系統管理員，並得到您需要配置的Exchange Server的名稱。

OK當我這樣做時，如何配置任何示例代碼？ –

您應該檢查這些設置併爲主機名提供正確的值 - –

我實際上在源代碼中找到所有設置。（但（）（（（（（ –

有時smtp服務器是不同的，你正在看。爲如：我的電子郵件是[email protected]，我的實際SMTP服務器 server1.mail.mycompany.com，server2.mail.mycompany.com 你要問您的管理該服務器名稱

之後，要求你的用戶是否在AD上定義，是否需要驗證每個smtp發送？

您的交換主機是否使用基於TLS的SMTP？ AFAIK某些交換管理員使用SMTP over SSL或TLS聲明。您可以通過爲其電子郵件獲取當前交換/窗口證書來查看有關通過SSL或TLS使用SMTP發送的MSDN文檔。

試過了上面的解決方案，但它沒有編譯一些尷尬的錯誤......我剛剛收到我們的源代碼的訪問權限，所以我會去那裏查看詳細信息關於交換服務器 –

試試這個獨立的C＃應用程序，看看主機名是否工作。否則，您需要聯繫管理員以獲取正確的地址。

 string _SMTP = WebConfigurationManager.AppSettings["SMTP"]; 
     Int32 _Port = Convert.ToInt16(WebConfigurationManager.AppSettings["Port"]); 
     string _SMTPCredentialName = WebConfigurationManager.AppSettings["SMTPCredentialName"]; 
     string _SMTPCredentialPassword = WebConfigurationManager.AppSettings["SMTPCredentialPassword"]; 
     string _Body = null; 

     System.Net.Mail.MailMessage _MailMessage = new System.Net.Mail.MailMessage(); 
     try 
     { 
      _MailMessage.To.Add(_RegUserEmail); 
      _MailMessage.From = new System.Net.Mail.MailAddress(_FromEmail, _FromName); 
      _MailMessage.Subject = _Subject; 
      _Body = ReadTemplateRegistration(_RegisterName, _RegUserName, _RegUserEmail, _Pass, _Path); 
      _MailMessage.BodyEncoding = System.Text.Encoding.GetEncoding("utf-8"); 

      AlternateView plainView = AlternateView.CreateAlternateViewFromString(System.Text.RegularExpressions.Regex.Replace(_Body, "<(.|\\n)*?>", string.Empty), null, "text/plain"); 
      AlternateView htmlView = AlternateView.CreateAlternateViewFromString(_Body, null, "text/html"); 

      _MailMessage.AlternateViews.Add(plainView); 
      _MailMessage.AlternateViews.Add(htmlView); 

      System.Net.Mail.SmtpClient mailClient = new System.Net.Mail.SmtpClient(_SMTP, _Port); 

      System.Net.NetworkCredential basicAuthenticationInfo = new System.Net.NetworkCredential(_SMTPCredentialName, _SMTPCredentialPassword); 

      mailClient.UseDefaultCredentials = false; 

      mailClient.Credentials = basicAuthenticationInfo; 

      _MailMessage.IsBodyHtml = true; 

      mailClient.Send(_MailMessage); 
     } 
     catch (Exception ex) 
     { 

      return "ERROR" + ex.ToString(); 
     }

這是使用C＃發送郵件的最佳方法，您可以使用此方法的所有要去的電子郵件系統，包括交換服務器，POP3，SMTP，Gmail時，Hotmail的雅虎等
