Question

一旦我使用mandrill smtp服务器而不是 smtp.gmail.com ，系统会在第一次尝试时（随机）发送一些电子邮件并在第二次尝试时成功发送。我有一些类似的帖子，但没有解决我的问题。

这是异常跟踪跟踪（从数据库日志复制，请原谅我的跟踪格式错误）

System.Security.Authentication.AuthenticationException：对SSPI的调用失败，请参阅内部异常。 ---＆GT; System.ComponentModel.Win32Exception：指定的数据不可能解密---内部异常堆栈跟踪结束--- at System.Net.Security.SslState.StartSendAuthResetSignal（ProtocolToken 消息，AsyncProtocolRequest asyncRequest，异常异常）at System.Net.Security.SslState.CheckCompletionBeforeNextReceive（ProtocolToken 消息，AsyncProtocolRequest asyncRequest）at System.Net.Security.SslState.StartSendBlob（Byte [] incoming，Int32 count，AsyncProtocolRequest asyncRequest）at System.Net.Security.SslState.ProcessReceivedBlob（Byte []缓冲区，Int32 count，AsyncProtocolRequest asyncRequest）at System.Net.Security.SslState.StartReadFrame（Byte []缓冲区，Int32 readBytes，AsyncProtocolRequest asyncRequest）at System.Net.Security.SslState.StartReceiveBlob（Byte []缓冲区， AsyncProtocolRequest asyncRequest）at System.Net.Security.SslState.CheckCompletionBeforeNextReceive（ProtocolToken 消息，AsyncProtocolRequest asyncRequest）at System.Net.Security.SslState.StartSendBlob（Byte [] incoming，Int32 count，AsyncProtocolRequest asyncRequest）at System.Net.Security.SslState.ProcessReceivedBlob（Byte []缓冲区，Int32 count，AsyncProtocolRequest asyncRequest）at System.Net.Security.SslState.StartReadFrame（Byte []缓冲区，Int32 readBytes，AsyncProtocolRequest asyncRequest）at System.Net.Security.SslState.StartReceiveBlob（Byte []缓冲区， AsyncProtocolRequest asyncRequest）at System.Net.Security.SslState.CheckCompletionBeforeNextReceive（ProtocolToken 消息，AsyncProtocolRequest asyncRequest）at System.Net.Security.SslState.StartSendBlob（Byte [] incoming，Int32 count，AsyncProtocolRequest asyncRequest）at System.Net.Security.SslState.ProcessReceivedBlob（Byte []缓冲区，Int32 count，AsyncProtocolRequest asyncRequest）at System.Net.Security.SslState.StartReadFrame（Byte []缓冲区，Int32 readBytes，AsyncProtocolRequest asyncRequest）at System.Net.Security.SslState.StartReceiveBlob（Byte []缓冲区， AsyncProtocolRequest asyncRequest）at System.Net.Security.SslState.CheckCompletionBeforeNextReceive（ProtocolToken 消息，AsyncProtocolRequest asyncRequest）at System.Net.Security.SslState.StartSendBlob（Byte [] incoming，Int32 count，AsyncProtocolRequest asyncRequest）at System.Net.Security.SslState.ForceAuthentication（Boolean receiveFirst， Byte [] buffer，AsyncProtocolRequest asyncRequest）at System.Net.Security.SslState.ProcessAuthentication（LazyAsyncResult lazyResult）在System.Net.TlsStream.CallProcessAuthentication（Object 国家） System.Threading.ExecutionContext.RunInternal（执行上下文 executionContext，ContextCallback回调，对象状态，布尔值 preserveSyncCtx）at System.Threading.ExecutionContext.Run（执行上下文 executionContext，ContextCallback回调，对象状态，布尔值 preserveSyncCtx）at System.Threading.ExecutionContext.Run（执行上下文 executionContext，ContextCallback回调，对象状态）at System.Net.TlsStream.ProcessAuthentication（LazyAsyncResult result）at System.Net.TlsStream.Write（Byte []缓冲区，Int32偏移量，Int32大小）at System.Net.PooledStream.Write（Byte []缓冲区，Int32偏移量，Int32大小）在System.Net.Mail.SmtpConnection.Flush（）at System.Net.Mail.ReadLinesCommand.Send（SmtpConnection conn）at System.Net.Mail.EHelloCommand.Send（SmtpConnection conn，String domain）在System.Net.Mail.SmtpConnection.GetConnection（ServicePoint servicePoint）at System.Net.Mail.SmtpTransport.GetConnection（ServicePoint servicePoint）在System.Net.Mail.SmtpClient.GetConnection（）处 System.Net.Mail.SmtpClient.Send（MailMessage消息）at Nop.Services.Messages.EmailSender.SendEmail（EmailAccount emailAccount， String subject，String body，MailAddress from，MailAddress to， IEnumerable 1 bcc, IEnumerable 1 cc，String attachmentFilePath，String attachmentFileName）at Nop.Services.Messages.EmailSender.SendEmail（EmailAccount emailAccount， String subject，String body，String fromAddress，String fromName，字符串toAddress，字符串toName，IEnumerable 1 bcc, IEnumerable 1 cc， String attachmentFilePath，String attachmentFileName）at Nop.Services.Messages.QueuedMessagesSendTask.Execute（）

以下是用于发送电子邮件的代码块

 using (var smtpClient = new SmtpClient())
  {

            smtpClient.UseDefaultCredentials = emailAccount.UseDefaultCredentials;
            smtpClient.Host = emailAccount.Host;
            smtpClient.Port = emailAccount.Port;
            smtpClient.EnableSsl = emailAccount.EnableSsl;
            if (emailAccount.UseDefaultCredentials)
                smtpClient.Credentials = CredentialCache.DefaultNetworkCredentials;
            else
                smtpClient.Credentials = new NetworkCredential(emailAccount.Username, emailAccount.Password);
            smtpClient.Send(message);
   }

对SSPI的调用失败，请参阅内部异常。 ---＆GT; System.ComponentModel.Win32Exception：无法解密指定的数据
