Exceeded storage allocation. The server response was: 4.3.1 Message size exceeds fixed maximum message size

错误:

System.Net.Mail.SmtpException: Exceeded storage allocation. The server response was: 4.3.1 Message size exceeds fixed maximum message size
   at System.Net.Mail.DataStopCommand.CheckResponse(SmtpStatusCode statusCode, String serverResponse)
   at System.Net.Mail.SmtpConnection.OnClose(Object sender, EventArgs args)
   at System.Net.ClosableStream.Close()
   at System.Net.Mail.MailWriter.Close()
   at System.Net.Mail.SmtpClient.Send(MailMessage message)

 

Google翻译后是：超出存储分配。服务器响应为：4.3.1消息大小固定的最大邮件大小超过

 

措施：这是邮件带的附件太大造成超过IIS Smtp最大限制，默认是2048k。

         压缩邮件附件应该是正确的选择。
