There are external factors that can cause the operating system to generate email messages without property information. Addressing these external factors can reduce or eliminate this situation.

  • Use the Exchange Best Practices Analysis report and fix items related to old network card drivers, name resolution (DNS) problems, misconfiguraiton of SMTP connectors.
  • Issues relating to networking duplex settings may cause the operating system to generate this situation as well.
  • Upgrading to Symantec Mail Security Version 6.0.10 or later should correct this issue. Please upgrade to the latest version

Technical Information
The SMSMSE event sink component used for SMTP scanning, receives a NULL value for "IMailMsgProperties" argument (number 3 in the following declaration).

    HRESULT ISmtpInCommandSink::OnSmtpInCommand(
    [in] IUnknown *pServer,
    [in] IUnknown *pSession,
    [in] IMailMsgProperties *pMsg,
    [in] ISmtpInCommandContext *pContext);

IMailMsgProperties *pMsg is a reference to the MailMsg object housing the current message content and properties. SMSMSE crashes when it tries to call SMTP using pMsg (which could be NULL in this case).
